My problem resides in an increasingly falling performance in my program.

I'm building an environment where I use classes for animated objects. From my past experience in java I thought arrays would be the simplest way of handling the objects but it seems that the performance gets alot lower for every single addition to the size of the array... i.e. when adding just one object the performance is falling alot more than previous object.

Do you have any tips on another attack angle at this problem? I've tried playing around with framrates but as expected doesn't matter...

Edit: Changed the title to something more descriptive.

Basically I've got classes that places images at different coordinates depending on input. I think it's the way I load these images that is the flaw, I'm now trying to load them outside of classes and then use them as I initialize the instances of each class instead of loading them inside each instance of each class.

That should let me have just the one loaded image per class instead of one loaded image per instance of each class, right

(I'll see about cutting down the code size, it's fairly large with lots of comments so I'd rather not paste that in here).

These is a way to use only one global instance of an PImage in many classes. Whats slowed your app is loading the image in every draw() methode.

Code:

PImage img

void setup(){
	img=loadImage("myImage.gif");
}

void draw(){
	MyImageClass m=new MyImageClass(img);
	m.drawMe();
}

class MyImageClass{
	PImage myImage;
	
	MyImageClass(PImage i){
		myImage=i;
	}
	
	void drawMe(int x, int y){
		image(myImage, x, y);
	}
}
