How can I create a slider with two arrow buttons from the side? The arrows/triangle should turn white when clicked. And the slider should move each time the arrow button is clicked.
here's the link to what it should look like
and here's what I've done so far
int x=75;
void setup() {
size(600,400);
}
void draw() {
background(100);
fill (200);
rect (75, 25, 400, 50);
stroke(0);
if(mousePressed) {
if (mouseX >75 && mouseX <= 475)
{x=mouseX;}
}
fill(127,0,0);
rect (x, 20, 9, 60);
fill (255);
fill (200);
rect (10, 25, 50, 50);
{
if (mousePressed == true) {
fill(255);
} else {
fill(0);
}
triangle (50, 60, 50, 40, 15, 50);
}
fill (200);
rect (490, 25, 50, 50);
{
if (mousePressed == true) {
fill(255);
} else {
fill(0);
}
triangle (500, 60, 500, 40, 535, 50);
}
println(x);
}
When I click anywhere on the screen, my problem is that both arrows turn white. I need it to individually function. And the slider is not moving every time I click the arrow buttons
The following approach to this problem uses 4 different classes: ForwardArrow, BackArrow, Slider, and ValueField. Arrow fill color is controlled by the press() method of its respective class.
color BLUE = color(64, 124, 188);
color LTGRAY = color(185, 180, 180);
color YELLOW = color(245, 250, 13);
color RED = color(255, 0, 0);
color BLACK = color(0, 0, 0);
color WHITE = color(255, 255, 255);
color GREEN = color(32, 175, 47);
ForwardArrow _fwdArrw;
BackArrow _backArrw;
ValueField _valueFld;
Slider _slider;
final int _sliderX = 90;
final int _sliderY = 40;
final int _sliderW = 200;
final int _sliderH = 30;
final int _txtSize = 22;
final int _initValue = 40;
final int _maxValue = 200;
final int _minValue = 0;
int value = _initValue;
class ValueField {
float x, y, w, h;
String title;
color fldColor;
color txtColor;
// Constructor
ValueField(int xpos, int ypos, float wt, float ht, String valueStr, color background, color foreground) {
x = xpos;
y = ypos;
w = wt;
h = ht;
title = valueStr;
fldColor = background;
txtColor = foreground;
}
void display(int val) {
// **** Value Field **** //
fill(fldColor); // erase old value
rect(x, y, w, h);
fill(txtColor); // text color
textSize(_txtSize);
textAlign(CENTER);
text(str(val), x, y, w, h);
// **** Slider bar **** //
fill(255);
rect(_sliderX, _sliderY, _sliderW*val/_maxValue, _sliderH);
}
}
class ForwardArrow {
float x, y, w, h;
color arrwColor;
// Constructor
ForwardArrow(int xpos, int ypos, float wt, float ht, color background) {
x = xpos;
y = ypos;
w = wt;
h = ht;
arrwColor = background;
}
void display() {
fill(arrwColor); // arrow color
noStroke();
triangle(x, y, x, y + h, x + w, y + h/2 );
}
void press() {
fill(255); // arrow color
noStroke();
triangle(x, y, x, y + h, x + w, y + h/2 );
}
}

triangle(x, y + h/2, x + w, y, x + w, y + h );
}
}
class Slider {
float x, y, w, h;
color barColor;

A revision of your code follows;
int x=75;
void setup() {
size(600, 400);
}
void draw() {
background(100);
fill (200);
rect (75, 25, 400, 50); // slider bar
stroke(0);
fill(127, 0, 0);
rect (x, 20, 9, 60); // slider thumb
fill (200);
rect (10, 25, 50, 50); // back arrow
fill(0);
triangle (50, 60, 50, 40, 15, 50);
if ((mouseX >= 10) && (mouseX <= 10 + 50) && (mouseY >= 25) && (mouseY <= 25 + 50) ) {
if (mousePressed == true) {
fill(255);
triangle (50, 60, 50, 40, 15, 50);
x--;
if (x<75) {
x = 75; // minValue
}
} else {
fill(0);
triangle (50, 60, 50, 40, 15, 50);
}
}
fill (200);
rect (490, 25, 50, 50); //forward arrow
fill(0);
triangle (500, 60, 500, 40, 535, 50);
if ((mouseX >= 490) && (mouseX <= 490 + 50) && (mouseY >= 25) && (mouseY <= 25 + 50) ) {
if (mousePressed == true) {
fill(255);
triangle (500, 60, 500, 40, 535, 50);
x++;
if (x>466) {
x = 466; // maxValue
}
} else {
fill(0);
triangle (500, 60, 500, 40, 535, 50);
}
}
}
You've got part of the logic right for the slider/trackbar so it changes x only within a range. This happens horizontally only at this stage, but you can use the same logic to check horizontal limits as well. Similarly, you can check if the cursor is within the bounds of any rectangle (be it the slider or either of the buttons):
int x=75;
void setup() {
size(600, 400);
}
void draw() {
background(100);
// slider
fill (200);
rect (75, 25, 400, 50);
stroke(0);
if (mousePressed) {
if (mouseX >75 && mouseX <= 475)
{
x=mouseX;
}
}
fill(127, 0, 0);
rect (x, 20, 9, 60);
fill (255);
// left arrow button
fill (200);
rect (10, 25, 50, 50);
fill(0);
if (mousePressed == true) {
if (mouseX > 10 && mouseX <= 10 + 50 && mouseY > 25 && mouseY <= 25 + 50){
fill(255);
}
}
triangle (50, 60, 50, 40, 15, 50);
// right arrow button
fill (200);
rect (490, 25, 50, 50);
fill(0);
if (mousePressed == true) {
if (mouseX > 490 && mouseX <= 490 + 50 && mouseY > 25 && mouseY <= 25 + 50){
fill(255);
}
}
triangle (500, 60, 500, 40, 535, 50);
println(x);
}
Wouldn't it be nice if you could take that logic and instead of copy/pasting the different x,y,width,height parameters for the same 4 statements you could group that functionality in a reusable block of code ?
That what functions are for. You're already using them already (defining setup()/draw(), calling background()/fill()/etc.
The Processing Button example already provides the boolean overRect(int x, int y, int width, int height) function which is perfect for you're trying to achieve: pass in the x,y,width,height or a button and get back boolean value.
Here's your code using the overRect():
int x=75;
void setup() {
size(600, 400);
}
void draw() {
background(100);
// slider
fill (200);
rect (75, 25, 400, 50);
stroke(0);
if (mousePressed) {
if (mouseX >75 && mouseX <= 475)
{
x=mouseX;
}
}
fill(127, 0, 0);
rect (x, 20, 9, 60);
fill (255);
// left arrow button
fill (200);
rect (10, 25, 50, 50);
fill(0);
if (mousePressed && overRect(10, 25, 50, 50)) {
fill(255);
x--;
}
triangle (50, 60, 50, 40, 15, 50);
// right arrow button
fill (200);
rect (490, 25, 50, 50);
fill(0);
if (mousePressed && overRect(490, 25, 50, 50)){
fill(255);
x++;
}
triangle (500, 60, 500, 40, 535, 50);
// ensure x remains within the slide limits
x = constrain(x, 75, 475);
println(x);
}
boolean overRect(int x, int y, int width, int height) {
if (mouseX >= x && mouseX <= x+width &&
mouseY >= y && mouseY <= y+height) {
return true;
} else {
return false;
}
}
How do I create a random car barrier for my game? I have this top-down car game that I need to make. This game aims to make the car move up and down (on the y-axis) to avoid the barriers, while the barriers are moving toward the car (on the x-axis). Is it possible to create a random generation of the barriers when they spawn, making the game enjoyable? Right now, I only have a set of barriers that last for 12 seconds before I get easily through them. Can I also keep the spacing of the barriers the same? So the car can fit.
code
color green = color(0,195,0);
color red = color(195,0,0);
color grey = color(100,100,100);
color yellow = color(200,200,0);
color white = color(255,255,255);
float roadx = 70, road1y = 130;
float road2y = 230, road3y = 330;
float carY = road2y;
float carX = roadx;
float carUPspeed = 1;
float laneX = 700;
float lanes;
void lane1(float x, float y){
fill(white);
rect(x + 100, y,30,100);
rect(x + 250, y + 100,30,100);

I've modified your lane rendering and added dynamic creation of barriers. Every 150 pixels moved, the barriers are updated (leftmost barriers are removed, new ones are added at the rightmost position and the cycle starts over).
The barriers are stored as an integer between 0 and 6, as there are 7 possibilities for the barrier positions:
int | 0 1 2 3 4 5 6
------+--------------------
lane0 | # # #
lane1 | # # #
lane2 | # # #
Hope this helps.

I am working on creating a random dungeon generator for a game I am going to make. I just barely did the basics. In order to avoid having to make 20 different variables for the 20 different rectangles I drew, I used two arrays called rx and ry. However, when I went to draw the rectangles using:
rect(rx[19], rx[19], 50, 50)
It didnt put the last rectangle in the correct spot. Rather than putting it at the value that is determined by my code, it always puts rectangle 19 at 0, 0. I am not entirely sure that it is in fact rectangle 19, but I'm assuming it is. I made my two arrays using:
int[] rx = new int[20];
and
int[] ry = new int[20];
Anything helps. Here is the rest of my code just in case it will be useful, however, if you would like me to only give the important bits, tell me. Thanks!

Got it answered by #Jeremy Kahan. I just had to set i to -1 and it fixed itself!
Since this was my answer, I'm writing it as an answer. The key was to initialize int i = -1; rather than int i = 0;
It works because since the first thing you do inside your if block is i++, you were working with 1, 2, 3, ..., 18, and 19, but never with index 0. Starting at -1 fixed that so you worked with all twenty entries (whose indices are 0 to 19).
I have a game in Processing and there are two classes - main and player. I'm thinking the main class should have the setup and menu, and the player class have the controls, collision, movement etc.
I need help figuring out how to connect the two classes so the game can run. In the main class some variables and methods are not defined so I know I'm not referencing or calling them right.
I'm fairly new to classes and methods so any help would be appreciated. Thanks!

I'm getting this error: The nested type cannot hide an enclosing type. I have looked it up, and other people seem to be declaring their class twice, which I am not.
What's weird is if I copy and paste the code into a new processing document, it works with no error. But as I'm converting it to js i need it to work with no errors after saving and opening again.

Your problem is caused by the fact that you're naming your sketch the same thing as a class you're using inside your sketch. Your sketch can't be named MotorBike if you have a MotorBike class inside that sketch.
Either rename your sketch, or rename your class.
Behind the scenes, this is because Processing exports your sketch as a Java class, and any classes in your sketch become inner classes of that Java class. So your sketch becomes something like this:
class MotorBike{
void draw(){
//whatever
}
class MotorBike{
int x;
//whatever
}
}
This is illegal Java, which is what's causing your error. You can't have an inner class with the same name as a parent class. In other words, a nested type cannot hide an enclosing type.
This is also why it works okay when you copy it into a new sketch- Processing gives your sketch a random default name, so you don't have this name collision until you save your sketch as something else.
