I need to draw some 2D objects on a canvas in java (rectangles, windows like)
The main goal will be to map 2D coordinates to objects, e.g. to recognize which object was clicked.
Question:
What is the usual way to maintain 2D Object’s size / position. (which datastructures etc.)
There should be an effective way to say, which object is at coordinates x,y
What i was looking for – was a Quadtree
For less complicated structures an Array would do.
