Rectangle To Rectangle Collision Detection
There is a built in method for testing collisions between rectangles.
BOOL colide = CGRectIntersectsRect(rect1, rect2);Here is a method I wrote before I new the former had existed.
- (BOOL) rect:(CGRect) rect collisionWithRect:(CGRect) rectTwo
{
float rect_x1 = rect.origin.x;
float rect_x2 = rect_x1+rect.size.width;
float rect_y1 = rect.origin.y;
float rect_y2 = rect_y1+rect.size.height;
float rect2_x1 = rectTwo.origin.x;
float rect2_x2 = rect2_x1+rectTwo.size.width;
float rect2_y1 = rectTwo.origin.y;
float rect2_y2 = rect2_y1+rectTwo.size.height;
if((rect_x2 > rect2_x1 && rect_x1 rect2_y1 && rect_y1
