Collision Between Two Squares

• Much less math here.
• We can make a geometrical argument
  • Is any corner of one square "inside" the other square.
    • If so, we have a collision.
  • But this is not quite enough
    • We have the condition where two squares form a + sign.
    • Then we need to check if the top or bottom edges of first square is between the top and bottom edges of the second square
    • AND if the left or right edges of the second square are between the left and right edges of the first square.
• For a collision test, I just built a bounding box around the circle.
