Hmmm. In order for it to detect a collision or overlap i guess i would need 2 At least 2 BBox values intersecting with 2 BBox values of another Sprite.
Condition1 - Sprite1.BBoxLeft & Sprite1.BBoxTop (X and Y of Top left corner of the first sprite) < Sprite2.BBoxRight & Sprite1.BBoxBottom (Lower right corner of Sprite2) if true, that would indicate that the two Sprites BBoxes are intersecting on at least one corner?
Maybe it would be good to add a X & Y instance variable for each corner of a Sprite BBox. I guess i would get values like this for a 100pixel square box.
Then it would be pretty easy to check if there is any intersections with any other sprite.
Continuing my experimentations, think I'm getting there.
