Java2D Game Running 20-30 FPS
I am writing a java2D game that as of now has an almost perfect memory footprint running only at around 2% of about a 4GB usable RAM space. The problem is the game only is running at around 20-30 fps just from rendering the character and the surrounding environment. I read already something about utilizing the GraphicsConfiguration, but when I tried that my fps soared right up to 120-130 fps while my memory increased to 70-80% and the frame was frozen in one place even if i moved the character. At this point I am stuck. I assume it has something to do with how many times i call g2d.fillRect() because after removing an area that's being referenced the game seems to speed up. The game seems to run smoothly at 20-30 fps, but I need to fix this otherwise my viewable gameobject painter loop will reduce my game to nothing but lag.
Rendering Method With Clipping Areas
private void renderEnvironment(Graphics2D g2d){
for(int paint_index = 0; paint_index < paint_textures.size(); paint_index++){
TexturePaint current_paint = paint_textures.get(paint_index);
//Area a = new Area(new Rectangle(0, 0, host_frame.getWidth(), host_frame.getHeight()));
//a.intersect(new Area(AffineTransform.getTranslateInstance(CamX, CamY).createTransformedShape(paint_regions.get(current_paint))));
g2d.setPaint(new TexturePaint(current_paint.getImage(), new Rectangle(CamX, CamY, current_paint.getImage().getWidth(), current_paint.getImage().getHeight())));
g2d.setClip(AffineTransform.getTranslateInstance(CamX, CamY).createTransformedShape(paint_regions.get(current_paint)));
//g2d.fill(a);
g2d.fillRect(0, 0, host_frame.getWidth(), host_frame.getHeight());
}
for(int paint_index = 0; paint_index < animated_textures.size(); paint_index++){
TextureAnimation current_paint = animated_textures.get(paint_index);
//Area a = new Area(new Rectangle(0, 0, host_frame.getWidth(), host_frame.getHeight()));
//a.intersect(new Area(AffineTransform.getTranslateInstance(CamX, CamY).createTransformedShape(paint_regions.get(current_paint))));
g2d.setPaint(new TexturePaint(current_paint.animatedPaint().getImage(), new Rectangle(current_paint.animatedPaint().getAnchorRect().getBounds().x + CamX, current_paint.animatedPaint().getAnchorRect().getBounds().y + CamY, current_paint.animatedPaint().getImage().getWidth(), current_paint.animatedPaint().getImage().getHeight())));
g2d.setClip(AffineTransform.getTranslateInstance(CamX, CamY).createTransformedShape(paint_regions.get(current_paint)));
//map_graphics.fill(a);
g2d.fillRect(0, 0, host_frame.getWidth(), host_frame.getHeight());
}g2d.setClip(null);
g2d.drawImage(character_sprite.spriteImage(), host_frame.getWidth() / 2, host_frame.getHeight() / 2, host_frame);
for(int paint_index = 0; paint_index < global_textures.size(); paint_index++){
TextureAnimation current_paint = global_textures.get(paint_index);
g2d.setPaint(new TexturePaint(current_paint.animatedPaint().getImage(), new Rectangle(current_paint.animatedPaint().getAnchorRect().getBounds().x + CamX, current_paint.animatedPaint().getAnchorRect().getBounds().y + CamY, current_paint.animatedPaint().getImage().getWidth(), current_paint.animatedPaint().getImage().getHeight())));
//g2d.setClip(new Rectangle(0, 0, host_frame.getWidth(), host_frame.getHeight()));
g2d.fillRect(0, 0, host_frame.getWidth(), host_frame.getHeight());
}
}
EDIT : TextureAnimation.java
public class TextureAnimation implements ActionListener {
private final Action behavior;
private final BufferedImage image;
private final Component host;
private TexturePaint paint;
private final Timer t;
private final boolean isGlobal;
public int x;
public int y;
public TextureAnimation(Action a, BufferedImage i, Component c, boolean global){
isGlobal = global;
behavior = a;
image = i;
host = c;
paint = new TexturePaint(image, new Rectangle(0, 0, image.getWidth(), image.getHeight()));
t = new Timer(300, this);
t.setInitialDelay(0);
}
public void playAnimation(){
t.start();
}
public Boolean isGlobal(){
return isGlobal;
}
public void delayAnimation(int ms_delay){
t.setInitialDelay(ms_delay);
t.restart();
}
public void setIntervalDelay(int ms_delay){
t.setDelay(ms_delay);
}
public void setTilePosition(int x, int y){
paint = new TexturePaint(image, new Rectangle(Gscale.setX(x), Gscale.setY(y), Gscale.setWidth(image.getWidth()), Gscale.setHeight(image.getHeight())));
}
public TexturePaint animatedPaint(){
return paint;
}
@Override
public void actionPerformed(ActionEvent e) {
behavior.actionPerformed(new ActionEvent(this, ActionEvent.ACTION_PERFORMED, null));
//host.repaint(0,0, host.getWidth(), host.getHeight());
}
}

Java2D Performance Issues
Note : The Graphic2D parameter is taking on the graphics of the JPanel itself. So shouldn't java already create a Compatible image for me?
