Hello I am developing a game on my spare time with AIDE and libGDX. Though AIDE has some missing methods of the libGDX API and I had to create some workarounds to compensate for the missing methods. So my problem is that with every instance of a collision the app becomes more and more laggy. No new textures are being drawn and non go away. Just a poor implementation that is meant to push you out of said collision tile. It runs fine until you have a few collisions. My thought is that it creates a new variable with every collision and stores it into memory causing a leak. But I can't really tell if that is the case. Oh I'd like to add that I don't have access to a computer, just my phone. Here is my movement class
move.java
public class move
{
float posX;
float posY;
float touchedOnScreenX;
float touchedOnScreenY;
float centerOfScreenX;
float centerOfScreenY;
float posXSetter;
float posYSetter;
float Speed = 150;
float mapBoundsWidth;
float mapBoundsHeight;
boolean upperBounds;
boolean lowerBounds;
boolean rightBounds;
boolean leftBounds;
boolean tileCollition;
public move() {
}
public void renderMove(float delta) {
if(Gdx.input.isTouched()) {
screenAndTouchInfo();
checkBoundsBoolean();
checkForCollision();
}
}
//slows game down
private void checkForCollision()
{
if (upperBounds == false)
{
if (lowerBounds == false)
{
if (rightBounds == false)
{
if (leftBounds == false)
{
if (tileCollition == false)
{
movement();
}
else
{
collitionSide();
}
}
else
{
posX++;
}
}
else
{
posX--;
}
}
else
{
posY++;
}
}
else
{
posY --;
}
}
private void movement()
{
posYSetter = posY;
posXSetter = posX;
if (touchedOnScreenX < centerOfScreenX)
{
posX -= Gdx.graphics.getDeltaTime() * Speed;
}
else
{
posX += Gdx.graphics.getDeltaTime() * Speed;
}
if (touchedOnScreenY < centerOfScreenY)
{
posY -= Gdx.graphics.getDeltaTime() * Speed;
}
else
{
posY += Gdx.graphics.getDeltaTime() * Speed;
}
if (touchedOnScreenY < centerOfScreenY + 64 && touchedOnScreenY > centerOfScreenY - 64)
{
posY = posYSetter;
}
if (touchedOnScreenX < centerOfScreenX + 64 && touchedOnScreenX > centerOfScreenX - 64)
{
posX = posXSetter;
}
}
//buggy and slows game down. Can push you into tile if input is the opposite of the side
public void collitionSide() {
if (tileCollition == true){
if (touchedOnScreenX < centerOfScreenX)
{
posX = posX +10;
}
else
{
posX = posX - 10;
}
if (touchedOnScreenY < centerOfScreenY)
{
posY = posY +10;
}
else
{
posY = posY -10;
}
}
}
private void screenAndTouchInfo()
{
touchedOnScreenX = Gdx.input.getX();
touchedOnScreenY = (Gdx.graphics.getHeight() - Gdx.input.getY());
centerOfScreenX = Gdx.graphics.getWidth() / 2;
centerOfScreenY = Gdx.graphics.getHeight() / 2;
}
//slows game down
private void checkBoundsBoolean()
{
if (posX > mapBoundsWidth)
{
rightBounds = true;
}
else {
rightBounds = false;
}
if (posY > mapBoundsHeight)
{
upperBounds = true;
}
else {
upperBounds = false;
}
if (posX < mapBoundsWidth - mapBoundsWidth)
{
leftBounds = true;
}
else {
leftBounds = false;
}
if (posY < mapBoundsHeight - mapBoundsHeight)
{
lowerBounds = true;
}
else {
lowerBounds = false;
}
}
public void setTileCollision(boolean tileCollision) {
this.tileCollition = tileCollision;
}
public float getPosX() {
return posX;
}
public float getPosY() {
return posY;
}
public float getTouchedOnScreenX() {
return touchedOnScreenX;
}
public float getTouchedOnScreenY() {
return touchedOnScreenY;
}
public float getCenterOfScreenX() {
return centerOfScreenX;
}
public float getCenterOfScreenY() {
return centerOfScreenY;
}
public void setMapboundsWidth(float width) {
this.mapBoundsWidth = width;
}
public void setMapboundsHeight(float height) {
this.mapBoundsHeight = height;
}
}
I know that is a lot of code to comb through and I am sorry if it isn't always clear what is going on. I refactored it to where it would be a little easier to understand. Oh if anyone could tell me why AIDE is missing some methods of libGDX that would be nice too.The most notable one would be Cell.setTile(). That I know is in libGDX's API and can be found in their documentation. But when I implement it it throws a unknown method of class Cell error. I have researched on how to use the method as well with no avail. Had to create int[][] map and a for loop to draw map with another Texture[]. It works. Lol. Thank you to whomever even took the time to look at my long winded double question. Hopefully someone can tell me why this lag is created from said collisions.
I recommend moving your collision code into a separate thread. This should improve performance significantly:
Executor executor = Executors.newSingleThreadExecutor();
executor.execute(new Runnable() {
@Override
public void run() {
// Physics loop goes here
}
});
Make sure to shutdown the executor when disposing your screen.
