Code Snippets > Collisions and Physics ( Created 06 March 2009 | Last Edited 06 March 2009) Box/Circle collisions by Jayenkai | No Votes Really really simple bog standard collisions.. Written in Blitz Graphics 800,600,32,2 SetBuffer BackBuffer() Repeat Cls Oval MouseX()-32,MouseY()-32,65,65,0 Rect MouseX()-32,MouseY()-32,65,65,0 Color 255,255,255 If Sqr(((100-MouseX())*(100-MouseX())) +((400-MouseY())*(400-MouseY())) )<65 Then Color 255,0,0 Oval 100-32,400-32,65,65,0 Color 255,255,255 If Abs(700-MouseX())<65 And Abs(400-MouseY())<65 Then Color 0,0,255 Rect 700-32,400-32,65,65,0 Flip Until KeyDown(1) --> Just your basic bog standard collision stuff. Box vs Box = Abs(x) and Abs(y) checks. Circle vs Circle = Sqr((x*x)+(y*y)) check. (Pythagoras) Probably useful for folk! There are no comments for this entry.
