For C++, Java, or Python, what are some good game + free game engines that are easy to pick up?
Any type of game engine is okay. I just want to get started somewhere by looking into different game engines and their capabilities.

For my Computer Graphics course in College we used the open source OGRE 3D engine. Not only is this an extremely robust 3D engine but it was a blast!
Develop a medium sized game using it and you will get a good taste of many of the different game programming specialties. You'll find yourself doing 3d modeling, sound effects, physics programming, AI, the works.

Java hasn't got any love here? For 2D and 3D OpenGL on win/mac/linux/android, try libgdx. For 2D with API similar to Java2D try Slick. LWJGL for pure OpenGL bindings. Ardor3D or JMonkeyEngine for a higher level 3D library. For networking, KryoNet.

I would suggest pygame It has work well for me in the past. It is very easy to use and comes with the bonus of python :)
It has an active community and works on both Unix and Windows. (I haven't tried it on Mac)

For python game development I would look into using panda3d.

Not really the language you want but I still think it's a good engine: Löve, and it's written in Lua.

Python
I've ditched Pygame and started using Pyglet.
It is extremely easy to play around with, it is nicely complete (OpenGL, mp3 support, image formats, joystick...), and it has a nice tutorial.

If you are ready for deeper mechanics but greater freedom, have a look at Crystal Space (C++), if you want to use more already-prepared objects you can consider the Irrlicht Engine (C++ too).

I'd recommend Ogre3D as well, it's rather extensive, cross-platform and you can add functionality like physics through existing add-ons - or write your own in C++. It is however a graphics engine, rather than a dedicated game engine, but the add-ons amend that.
More importantly there are wrappers for Python (Python-Ogre), Java (ogre4j) and .Net (MOGRE).

I heard good things about Ogre, but i haven't used it myself.
In a completely different area, i think Blender has been complemented with interaction capabilities.

Many open source projects are hosted on launchpad, some are games, and some of those use a 3rd party engine. Maybe you could have a look there?

Garry's Mod was written using Half-Life 2's Source engine, presumably using the Hammer editor.
Granted, this is arguably closer to level design than game design, but might be interesting regardless.

On the Java front, check out jMonkeyEngine. It's got a lot of features including hardware acceleration using OpenGL. I haven't attempted to develop anything using it, but I've been following the community for a while; they did a demo and presentation a few JavaOnes ago.
Moving from the client to the server, if you are interested in toolkits for building MMOGs, then check out Project Darkstar. It's a server-side framework (written in Java) with client-side SDKs for Java and C. The whole project is sponsored by Sun.

If you're interested in 3D game programming, id Software of Doom and Quake fame often release the source code for their engines. You can find the source code for Quake I, II and III here and a substantial chunk of the Doom 3 code here and Quake IV here.

There is a RPG engine called VERGE if you're interested. Never tried it but I heard good things from it.
I think it's in C++.

Game Engine Remake - Trouble Choosing a Language /API(Java or Python) [closed]

The engine I've been wanting to remake is from a PlayStation 1 game called Final Fantasy Tactics, and the game is basically a 2.5D game I guess you could say. Low-resolution sprites and textures, and 3D maps for battlefields. The plan is to mainly load the graphics from a disc, or .iso (I already know the sectors the graphics need to be read from) and fill in the rest with game logic and graphics routines, and probably load other things from the disc like the map data.
I want this to be a multiplatform project, because I use Linux and would like for more people to join in on the project once I have enough done (and it's easy to get more people through platforms like Windows). I'll be making a website to host the project. Also, none of the graphics will be distributed, they'll have to be loaded from your own disc. I'd rather not have to deal with any legal issues.. At least not soon after the project is hosted on my site.
But anyway, here's my dilemma- I know quite a bit of Java, and some Python, but I'm worried about performance/feature issues if I make this engine using one of these two languages. I chose them due to familiarity and platform independence, but I haven't gotten too into graphics programming yet. I'm very much willing to learn, however, and I've done quite a bit of ASM work on the game- looking at graphics routines and whatnot. What would be the best route to take for a project like this? Oh, and keep in mind I'll eventually want to add higher-resolution textures in an .iso restructuring patch or something.
I'm assuming based on my results on Google that I could go with something like Pygame + OpenGL, JOGL, Pyglet, etc. Any suggestions on an API? Which has plenty of documentation/support for game or graphics programming? Do they have any serious performance hits?
Thank you for your time.
I'd recommend going with PySFML, and, of course, Python.
If you do your Python programming correctly , and if you really are willing to fiddle with C or ASM Python plugins for faster computations, you shouldn't really have too much performace hits.
First thing, I wouldn't worry too much about language performance at this moment. If you worry about performance unnecessarily and choose the wrong/hard platform, your project will be dead before it started..because it will take it longer for you to produce something and harder to get other people to join your project.
Since your are familiar with Java & Python, I'll suggest do your project with Jython or JRuby. That way you get to write in nice and powerful language with the benefit of Java runtime.
By choosing to run it on Java runtime you get:
Multi platforms support, so this address your concern about linux/window platform.
Latest Java runtime is very good and in most cases the JIT can perform equal or better to natively compiled program.
At the end of the day if you're passionate about the project and committed to getting the most out of the language you choose, the performance difference between java and python will be minimal if non-existent.
Personally speaking, the biggest challenge is finishing the project once it loses novelty and initial momentum. I suggest you go with whichever language you're more passionate about and are interested in plumbing the depths of, or one that could boost your resume.
Secondly, as you mention you're hoping to attract contributors, you may want to factor that into your decision. I can't comment much here, but have a look at similar projects with lots of activity.
Good luck!

I'm looking into writing my first application of Google App Engine. C# is my 'native' language, and so writing the app in Java would of course be most logical. BUT, I'm a geek and would like to take to opportunity to learn something new.
Therefore its a toss-up between Python and Go.
Do you have a strong preference based on experience (ideally in the context of writing on App Engine).
If you've come from C# (or another similar language), how was the transition?
The recently-released Go runtime for App Engine is labelled experimental for a reason: Both Go and Go-on-appengine are new and in a state of change.
If you want to experiment with Go and running Go apps in the cloud, go for it. If you want to write a production app on App Engine, use Python or Java.
This question is about as subjective as they come, but I'll bite anyway.
Python is easier to learn, has a much larger development community, is mature, and has a lot of third-party libraries available for you to integrate into your application. It's a winner for sure.
That said, Go is an extremely well-designed language. Far, far more so than Python. Go was specifically designed to allow you to catch most mistakes at compile time, while Python is almost legendary for its ability to mask your mistakes. Go code tends to be easier to maintain. Go is also dramatically more efficient than Python -- several times faster or even several orders of magnitude faster, depending on what you're doing.
Both languages are very powerful and very fast to write code in -- you can accomplish a lot in a short amount of space. But Go is unfinished and still in a state of flux, with core APIs still changing. It has a comparatively small developer base, and very few "real world" usage examples. Nonetheless, even this early in its development, it's already shown to be a compelling alternative with a clear use case.
I did a Python app for GAE recently and coming from C# I had no problems/was able to pick it up in a few days tinkering with the docs and playing with the SDK (I had some previous experience with python).
Python is pretty intuitive, it's imperative and OO, might require a slight change in thinking from C# but nothing revolutionary - using the interactive interpreter will allow you to pick it up in a day IMO.
Learning how to use the datastore and figuring out other GAE specific API's (blobstore, image, mail) will probably be more work (it's specifics like transactions/groups, consistency modes ...) but you can figure that stuff out as you go/when you need it in your app.
One thing to note - recently announced pricing scheme makes Python a bad choice on GAE ATM because it cannot handle requests currently and this leads to one "instance" per request. This is also true for Go ATM (as far as I know). JVM OTOH can handle ~20 simultaneous requests per instance if I remember the mailing list conversations correctly. And you will be paying per instance/hour. This makes JVM the most practical choice if you plan on publishing your application in the near future.
Also using JVM you could use Scala (a new/cool language) and a framework like Lift which should theoretically allow you to port your code/avoid lock-in (disclaimer : I say theoretically because I'm only starting out with Scala and have no practical experience with Lift).
So I would recommend to look around the mailing list and see what other people are saying about the recent changes.
Personally I would prefer Python because is much, much more mature than Go.
In the past, I learnt, the hard way, what are the risks of choosing a not-so-mature technology.
Warning, I am biased to recommend Python because I like it but you should also be careful because I heard many complains about how much support does Google put on Python-App-Engine. People are asking for years to upgrade Python support and nobody hears them.
These being said, probably Java would be a smarter choice, especially because you are used to C#.
Go is still experimental on the GAE - so maybe not the best platform to learn a new language. Python is definitely a good choice.
Considering a new language do not forget that by choosing Java you get the JVM which allows not only Java code but also oder languages like: Scala, Grails, Clojure, JRuby any many others.
Python is since long supported on GAE - lots of tested information, infrastructure, etc. Go is new to GAE.
I would decide more on the language level. Coming from C#, choosing Python you go a bit more "high-level", whereas choosing Go goes more into the "low-level" direction. More low-level control, but also more concern about that. Choose Python if your interest is on application development, and Go if it's more about systems development. One important aspect for me would be that Go has actor-style concurrency built in, though I don't know how well supported this on GAE will be.

Should I move from Java programming to Delphi programming? [closed]

over the years i have been employed in a permanent position with firms that did their development work in Windows SDK, VC++, and most recently Java; in my own eyes, I am language independent.
Should I move from Java to Delphi (assuming pay-scale remains unchanged)?
I'm concerned because, for the most part, the net presents a relatively bleak picture for this particular skill.
The TIOBE Index is an often cited source for estimating the popularity of programming languages. Java, C and C++ have been the top 3 for a very long time. As you can see, Delphi is a lot lower on the list (at position 10 at this moment). (Ofcourse you should not take the TIOBE Index as an absolute measure, but it does indicate something).
This can be an advantage as well as a disadvantage. There are probably a lot more Java and C++ jobs than there are Delphi jobs, but there are also a lot more Java and C++ programmers than Delphi programmers, so it's harder to stand out as a Java or C++ programmer among the masses. Having a specialism that not many people have, such as for example Delphi, may help you get a higher salary, though you'll have to search harder to find Delphi jobs.
Depends on what your goals are, but I believe that for regular apps the future bears name "GWT", i.e. Java. (I consider Delphi a history for quite a while, but that's JMO.)
It's definitely worth learning Delphi. A lot of software's still being written in it, stuff which people use and rely on. A lot of companies prefer to keep quiet about it, though, since it presents such a major competitive advantage over other, more popular languages.
For example, you ever work with VOIP on chat programs? In my experience, there are two basic categories: Skype, and The Other Stuff. Skype "just works", while the others tend to be very glitchy and unreliable. And it's no coincidence that Skype's written in Delphi while (AFAIK) none of the other chat programs are. That's just one example among many.
It never hurts to pick up another skill, but I haven't seen any Delphi job listings anywhere. I suspect you would be better suited picking up a new language/framework/platform with more "legs", such as WPF, JavaFX, Objective-C/Cocoa, ActionScript/Flex, or something of the like.
As a technical move, it's probably a good one -- Delphi is better thought out and more enjoyable to use. From a career perspective, however, you're probably right -- Delphi has been rather marginalized for some time now, and doesn't seem to be in the process of making a huge comeback.
I was using Delphi before I swtiched to C++ and then to Java. I don't think that moving from Java to Delphi is wise idea. Why so?
Java is widely used
It's easier to find Java job
More years of Java -> Better chance getting senior position job (java oriented)
Java is definitelly richer as for libraries
Java rocks in enterprise sphere, Delphi doesn't
It's easier to find resources for Java - from tutorials for beginners to manuals for professionals
Java runs on other operating systems by default, remember? (I know Lazarus, but can't compare port to nativeness)
From my exprience, more experienced programmers and software engineers kind of condemn Delphi programmers ...
Java is suitable for larger projects (means bigger money)
The only good reason for preferring Delphi over Java I can actually think of is making Windows GUI application. But since we have .NET and wonderful WPF, Delphi doesn't score even here.
You make your choice, but personally, I'd never switch back to Delphi (ok maybe if payment was too good to reject:))
The way you phrase your question makes me think you've got a job offer already for a Delphi developer position. If the language is the only thing stopping you, I say you should go for it.
It will add experience with another language to your resume besides being fun (learning something new). Just make sure you keep your skills in Java and C++ reasonably up to date when or if you need to move on.
Why limit yourself to one language?
A major problem with Delphi is that some people consider it an "easy" language. So there are Delphi programmers that can drag some controls to a form without any real coding knowledge. So if you are a good developer and skilled in Delphi, you won't have that much trouble finding a job.

I'm a beginner in programming. My experience so far is only in Actionscript 2 and 3. So I have a basic understanding of declaring variables, loops, arrays, if/then, do/while... I'm wanting to move to developing for Android phones so I'm wondering what suggestions people have for where to go next. Should I jump right to Android? Start with a 'beginning Java' approach? Or should I go some other route to beef up my knowledge of OOP concepts before launching into Android? I have my Dev environment set up and completed the Hello Android tutorial and I'm just wondering if I am going to be in over my head quickly?
I'm just wondering if I am going to be in over my head quickly?
Almost without a doubt. ^_^
My suggestion: Buy two books from Amazon.com
An Android development book. Work through every example in this book, do the problems at the ends of the chapters, take your time, understand what you're doing.
Buy an up-to-date Java book. Use it for reference when the Android book discusses something you don't understand.
This is very similar to what I did years ago to learn Obj-C and Mac development and it worked well. It will take you longer to get up to speed than diving into development and hacking something together, but at the end of the day you'll have a much better understanding of the principals and intricacies of writing code for the Android platform.
I should also mention my reasoning behind suggesting you buy books instead of using free Google results. Books are structured and highly edited. Assuming the author(s) are competent, a decent book will teach you what you need to know and leave out details that are either unimportant or more advanced that what you strictly need. It's difficult to impossible to find that level of structure in an online tutorial.
definitely nail down java syntax, so as little as possible confuses you in android development. android has some interesting objects to say the least--and their names don't hold traditional data structure names that you would be used to seeing. so, again, master the syntax, write some apps, then think about diving into android.
Yep, I'd say you need to learn java properly, and doing it exclusively through android is probably not the quickest approach. Try working your way through a recently published (it is essential that it covers generics) Java introduction book, then take on Android.
Android would be trial by fire. If you continue directly in Android, choose a few more simple hello world with bells on types of project. With ActionScript you were learning both a language and the platform, and switching to Android means learning a new language and very different platform. Most of the assumptions you acquired learning Flash will be wrong in Android.
I began learning Android with an understanding of JavaScript from front end web development. I grabbed the Wrox Android book and used the tutorials at http://java.sun.com/docs/books/tutorial/index.html to help me through the Java parts. I suggest diving head first into Android and going back to Java reference/tutorials where needed.

Game Programming as Hobby, should I use Java or C++ [closed]

Improve this question
Presently, i am learning Java from the book The Art and Science of Java and following Standford's Programming Methodology Course.
I would like to do game programming, but only as a hobby.
I was thinking, would Java be a good choice or is C++ the defacto in game programming.
Since you are learning Java i would recommend that you stick to it.
If you are only developing games for fun, it won't really matter what language you use.
That depends, do you want to learn more about C++? Do you need to know? There's still OpenGL libraries in Java that are available, and the concepts would essentially be the same regardless of what language you work in. If it's just for a hobby then I can't see anything wrong with working in Java. In terms of speed however, lower-level languages are prefered.
Either would be fine. For a hobby, they both have pretty good low-level support for graphics etc, and both also have pretty good higher-level libraries for games (jMonkey engine, SDL, SFML, Ogre and many more).
You could also consider other languages too. Python has SDL bindings called PyGame. C# has the XNA framework which has several books published for it now to help learning the framework. SFML has bindings for C++, C, D, Ruby and I think Python. All of these are then suitable for creating games in. Just pick a language and off you go.
If you ask me, neither Java or C++ are fun languages. Both of them have a number of advantages but if you're doing it for fun and don't have deadlines, I would seek out a language that's more fun. Like Python, or something similar.
If you want to make games you really need a game platform as well as a language, otherwise you will spend all your time solving basic problems like how to draw a sprite to the screen, rather than concentrating on building a fun game.
Great choices for hobby games development are:
Microft's XNA platform with C# language
Adobe's Flash with ActionScript language
Sun's JavaFX platform with JavaFX script language
Unity3D with C# language
Ogre with C++ language
You can write games using both languages but I think you should really try C++. There are far more high-level libraries and game engines written in C++ than Java so it would be easier to find one that suits your needs. Not to mention that a lot of older games have been open sourced and you can freely download them and study the code. You can guess what language they're using ;)
Also you'll find a lot more tutorials and books that teach game programming using C/C++.
No matter what you choose in the end, have fun writing your games :)
If you go with Java, I recommend Computer Graphics for Java Programmers, by Leen Ammeraal.
If you were developing commercial games you would be using libraries rather than implementing these algorithms yourself, but it's easier once you know the fundamentals, which you can learn from a book like this one.
I once wrote a software renderer for a DOOM clone in Java, and having this book for reference helped a lot.
C++ is THE defacto language not only for game development but for pretty much everything else, including the browser you are using along with the OS it runs on.
So if you are considering ever getting serious with programming C/C++ should be top at your list.
As for speed C++ IS generally fast than Java.
Why generally?Well, the truth is that C++ is faster than Java, is faster than pretty much everything else actually, but sometimes C++ code can be poorly written and Java may prevent beginners to make some mistakes resulting in many of the claims that Java is as fast as C++, there are even claims that Python/Psyco are as fast as C++ and faster than Java.
Keep in mind that no program written for a framework (Java, .NET, VB, etc) will ever run faster than a program that runs on a lower level (direct on the OS or even the hardware) like C/C++, ASM, Pascal and so on.
Take a look at this:
Poorly written C++ half the speed of Java, properly written is much faster
At the end of the day you should go with the language that you feel more comfortable with, remember that python is enterprise ready, commercial, stable, great for beginners, awesome to use on "Web 2.0" projects not to mention that is a lot of fun too.
Java - I'd recommend sticking to one and getting good at it. The ideas remain the same, and as you learn more about a single language, you'll begin to learn about the drawbacks and advantages that are prevalent in many of the programming methodologies and languages today.
Even if you never intend to get into professional game development there is one big advantage to C++, which is that you have a lot more resources available. There are more books, more tutorials online, more open source examples to look at and more people who will be able to answer your questions on sites like gamedev.net.
I have developed a couple of small games in both C++ and Java and I would select C++ everytime. It gives you the low level control which you just dont get with java. But games development is a whole different beast. So if you are looking to learn games developement start in something you are comofrtable with
If you think you may one day want to work in the industry, you should learn C++. C++ is used to make pretty much all commercial games that run on PC/xbox/ps3. I assume wii is the same but don't know 100%, I never worked on wii.
The games studio I used to work at (before it got shut down) used C++ for the game (small parts used C and assembler) and was starting to use C# for tools.
If it will only ever be a hobby, then it doesn't really matter what language you use.
I would suggest to try Haaf's Game Engine for C. It is very very simple 2D engine with good documentation, tutorials and examples, runs on Windows 98 and above and it is ABSOLUTELY free even for commercial usage!
If you're completely new to game development, it's right for you IMHO.
Only a hobby? If you're using Java then Java. But first, what are you programming, 2-D or 3-D games? Java does both, and it's my game programing language, but I'm doing only 2-D programs. C++ is the defacto standard for serious game programming, especially commercial games.
Java has a great IDE called Eclipse, which, to me, is worth doing Java all by itself...Eclipse rocks! And it's free.
C# - no. Way too Microsoft dependent.
Btw, Java will work as an applet and as an application if you plan it well, the application runnable on all three platforms...
So, think about it. Low investment, high quality tools, cross-platform. If you decide to get into C++, then that's okay too. At least you will have wet your toes for free...
;-)
Language defines target platform and public. Both Java and C++ have advantages and disadvantages. You will use same architectures and algorithms on any platform. If you know how to write a game in C++ it takes a little to write game in java (2 weeks for me http://madeinsoviets.net/).
Start learning game programming with C++ and some easy game engine (Ogre3D, irrlight) - much more information and tutorials.
Old topic but since people still read this i want to add my 2c since its unique
to this post.
Stick with java, its a great way to make games over c++ if your going to do it as a hobby
and by yourself for these 2 reasons.
10x less coding for the same results (albeit it runs about 5x
slower)
Android games, even mediocre ones will sell (a buck each) on the
marketplace. if you sell even one your going to feel huge pride!
(also java doesnt slow down over C++ on android because its JVM is
unique and runs against the API directly accessing hardware, which
is fantastic!)
If you are just doing it as a hobby, it probably doesn't matter. Just use whatever you are most comfortable so you can get into the swing of game programming. Once you get better, you might like to figure out what is the "best" language.
I would definitely suggest C++ if your intention is general game programming. Of course, if you want to develop for a mobile platform such as Nokia and Ericsson then Java might be a good idea.
But if it is for general desktop gaming then definitely C++. If you want to deploy games over the net then flash might also be a good idea.
If you're planning to enter the industry (or maybe a day start to sell your game yourself), then you have to learn C++.
Java or C# are good choice to get to the point of creating game without worrying much about the machine (memory and speed). That's recommended for beginner, but I would personally start directly with C++.
If you're looking into game programming then C++ is the way to go. Sure Java will be good for certain games, but C++ is so much faster.
I've coded in Java before, and then started coding in C++. The time I've spent coding in C++ made me understand certain things that were heavily simplified in Java.
Depending on how much experience you have programming, I'd suggest to learn the basics of Java and then move on to C++.
If you start with Java, I recommend this book Physics for Game Programmers
In general, C++ is for real games.
Java has always been slow for me, whatever platform or program I use.
C# is better than Java, but not as good as C++.
Yes, there are exceptions, but the fact that they are so notable rather proves that C++ is just the way to go unless you really know what you're doing.
