Buggy collision 2D platform game

Buggy collision 2D platform game - java

I'm building my first big project and I'm having trouble with the collision.
At first I used a println command in the collision detection and it worked great,so the problem is not with the detection itself I think.
This the movement code:
public void update() {
// Moves Character or Scrolls Background accordingly.
if (speedX > 0 && centerX <= 400){
centerX += speedX;
}
if (speedX < 0 && centerX >= 400){
centerX += speedX;
}
if (speedX > 0 && centerX >= 400){
bg1.setSpeedX(-MOVESPEED);
bg2.setSpeedX(-MOVESPEED);
}
if (speedX < 0 && centerX <= 400){
bg1.setSpeedX(MOVESPEED);
bg2.setSpeedX(MOVESPEED);
}
if (speedX == 0){
bg1.setSpeedX(0);
bg2.setSpeedX(0);
}
if(movingRight == true && movingLeft == true ){
bg1.setSpeedX(0);
bg2.setSpeedX(0);
}
// Handles Jumping
if (jumped == true) {
speedY += 1;
}
// Prevents going beyond X coordinate of 0
if (centerX + speedX <= 60) {
centerX = 61;
}
rect.setRect(centerX - 47, centerY - 65, 32, 87);
centerY += speedY;
}
public void moveRight() {
speedX = MOVESPEED;
}
public void moveLeft() {
speedX = -MOVESPEED;
}
public void stopRight() {
movingRight = false;
stop();
}
public void stopLeft() {
movingLeft = false;
stop();
}
private void stop() {
if (movingRight == false && movingLeft == false) {
speedX = 0;
}
if (movingRight == false && movingLeft == true) {
moveLeft();
}
if (movingRight == true && movingLeft == false) {
moveRight();
}
}
public void jump() {
if (jumped == false) {
speedY = JUMPSPEED;
jumped = true;
}
}
and this is the collision code:
public void checkCollision(Rectangle rect){
if (rect.intersects(r)){
if(Player.movingRight){
Player.centerX = tileX + 11;
Player.speedX =0;
}
if(Player.movingLeft){
Player.centerX = tileX + 89;
Player.speedX = 0;
}
if(Player.speedY > 0){
Player.centerY = tileY - 25;
Player.speedY = 0;
Player.jumped = false;
}
}
}
The problem is that it is very buggy, sometimes the player "teleports" and even falls threw the wall.

Ball going through paddle when increasing velocity

I am trying to create a Pong game and so far I have everything working for me other than the ball. At first I had the ball's x and y axis move up by one space each time. It was working fine until i decided to increase it to 2. I cant figure out what is wrong with my code and I need help.

Since you are moving by 2 every time, it may "skip" over some coordinates. Thus when you say
if (y == getHeight()-border){
balldown = false;
}
y might go from getHeight()-border + 1 to getHeight()-border - 1 and never meet this condition. Thus, change it to a range or a less than. Your new code should be
if (y <= getHeight()-border +1){
balldown = false; //change the +1 and -1 to have difference at least speed number
}
Note that you must do the same for the other ifs with ==, change
if (x == getWidth()-border){
ballright = false;
}
if (y == 0){
balldown = true;
}
if (x == 0){
ballright = true;
}
to
if (x <= getWidth()-border +1){
ballright = false;
}
if (y <= 1){
balldown = true;
}
if (x <= 1){
ballright = true;
}
Note that you can resolve the problem also by saying if the position is eer exactly one away from the border, temporarily decrement position by 1 instead of 2.

You are using if (x == 75) to detect collision with the left paddle. But if speed is 2 than the ball's x is always even and never equals 75. For a quick fix, check x against a range: if (x > 60 && x < 75)

Unusual bad program performance in Java

I'm a novice programmer, I'm make my first game in Java, and I just implemented a target AI, and now whenever I run it, always lags at start, I would like a explanation on why please or a way to do this better, Thank you in advance.

for(int i = 0; i < entity.size(); i++){
EntityObject tempObject = entity.get(i);
tempObject.render(g);
}
Your code includes several loops that look like this, and each take quadratic time, because they're running over LinkedList, which requires O(n) time for get. You should almost certainly be using an ArrayList, or at minimum, using a for-each loop, e.g.
for (EntityObject tempObject : entity) {
tempObject.render(g);
}

right now I am developing a chess game in java and have been writing the whole game in one java file without doing subclasses and I was hoping I could get some help with that
I want to separate the moves of all the pieces into a new file
can someone show me how to do that
This is the whole file below it is called ChessFrame,
I need help putting all the piece moves in a separate file called ChessMovement.java
I have tryed just taken out the movement but then that breaks everything I could really do with someone showing me

Any help would be great the code currently has no errors but I dont want to go any further til I have it separated out
thanks for any help

You need to create a Piece class, which has subclasses for all the piece types. Then create a FactoryPieceFactory.getPiece(pieceName, x pos, y pos, chessboard) to get those pieces, and implement a move() method on it which takes your new position, and does all the validation. This leaves your UI logic for rendering the moves here, but pushes the move logic down into the piece objects.
You will probably change this later to create a ChessBoard object, which will allow you to get a piece by it's x,y coordinates, and thus not know the piece's name. chessBoard.getPiece(x,y).move(newX, newY); That will allow you validate moves, plus deal with captures etc, calling back to the board to remove opposing pieces.

You mixed game-logic with GUI elements. You should use the concept of MVC. To refractor your program at this state is a question too unspecific.

Collision bug in a 2D platform game

I'm new to java, and game programming and I'm starting my first big project which is a 2D platform puzzle game.
This is my player movement code
if (speedX > 0 && centerX <= 400){
centerX += speedX;
}
if (speedX < 0 && centerX >= 400){
centerX += speedX;
}
if (speedX > 0 && centerX >= 400){
bg1.setSpeedX(-MOVESPEED);
bg2.setSpeedX(-MOVESPEED);
}
if (speedX < 0 && centerX <= 400){
bg1.setSpeedX(MOVESPEED);
bg2.setSpeedX(MOVESPEED);
}
if (speedX == 0){
bg1.setSpeedX(0);
bg2.setSpeedX(0);
}
if(movingRight == true && movingLeft == true ){
bg1.setSpeedX(0);
bg2.setSpeedX(0);
}
// Handles Jumping
if (jumped == true) {
speedY += 1;
}
// Prevents going beyond X coordinate of 0
if (centerX + speedX <= 60) {
centerX = 61;
}
rect.setRect(centerX - 47, centerY - 65, 32, 87);
centerY += speedY;
}
public void moveRight() {
speedX = MOVESPEED;
}
public void moveLeft() {
speedX = -MOVESPEED;
}
public void stopRight() {
movingRight = false;
stop();
}
public void stopLeft() {
movingLeft = false;
stop();
}
private void stop() {
if (movingRight == false && movingLeft == false) {
speedX = 0;
}
if (movingRight == false && movingLeft == true) {
moveLeft();
}
if (movingRight == true && movingLeft == false) {
moveRight();
}
}
public void jump() {
if (jumped == false) {
speedY = JUMPSPEED;
jumped = true;
}
}
and this is the collision code
public void checkCollision(Rectangle rect){
if (rect.intersects(r)){
if(Player.movingRight){
Player.centerX = tileX + 11;
Player.speedX =0;
}
if(Player.movingLeft){
Player.centerX = tileX + 89;
Player.speedX = 0;
}
if(Player.speedY > 0){
Player.centerY = tileY - 25;
Player.speedY = 0;
Player.jumped = false;
}
}
}
There are two problems.The first one is that if I press one of the movement keys when landing the character "teleports" to the right or left.
I know this happens because I programmed it that if the character intersects with the ground while movingRight or movingLeft are true he moves right or left.(I made it this way so the horizonal collision will work) and I cant think of any other way to do it or how to fix it.
The second problem is that if the character moves of a platfrom he does not fall down.
I tryed to fix it by adding to the collision method
else{
speedY += 1;
}
But it made the character disappear for some reason.
Thanks a lot!

This code was originally written in C++ for a 3D platformer. I rewrote it, but there might be some bugs. I can draw a picture later if it's difficult to understand.
public void checkCollision(Rectangle rect){
if(player.intersects(rect)) {
//the rectangles intersect, time to move the player out of the block
if(rect.y+rect.height >= player.y && rect.y+rect.height-0.7f < player.y) { //if the player is at most 0.7 units (you should change this!) below top side
player.y = rect.y+rect.height; //set player to stand on top
speed.y = 0f; //stop the movement
onGround = true;
} else if(rect.y+rect.height > player.y && rect.y < player.y+player.height) { //if the playeer is on the side, but not below
float xEscMinus = (float)Math.abs((rect.x+rect.width)-player.x); //find the distance to the side
float xEscPlus = (float)Math.abs(rect.x-(player.x+player.width));
if(xEscMinus<xEscPlus) {
player.x = rect.x+rect.width;
} else {
player.x = rect.x-player.width;
}
}
}
}

People can use their first person view to walk the library.It is fine in java mode,but when I put it in java script mode,the view has problem.So , which part of my code has problems so that it can not run on website?
Thank you very much.
