Collision detection problem

[BillLuvsU]

Ok, I am making a game and i need a function to tell if a picture in a gui is touching the color black (0xffffff). To be more descriptive i am outlining all borders of objects that cannot be walked through with black so that the picture cannot move through them. So black basically means wall.

I don't know if that's possible... I may be wrong, but what about setting limits on there X/Y coords?

There are DLL functions dealing w/ rectangle detection:

w/ the beta AutoIt you could use these functions.

ok,got it!

include<"guiconstants.au3">
global $picx = 195, $picy = 190
guicreate( "Test" , 400 ,400 )
guictrlcreatepic( "pic.bmp", $picx , $picy, 10, 20 )
guictrlcreatepic( "black.bmp", 100, 10, 10, 380 )
while 1
   ;insert functions to move pic.bmp here.
    $collision = _CollisionDetect( $picx - 1, $picy - 1, $picx +  11, $picy + 21, "0xffffff" )
wend

Func _CollisionDetect
    $pixel = PixelSearch( $picx - 1, $picy - 1, $picx +  11, $picy + 21, "0xffffff" )
    if @error then Return 0
    ElseIf $pixel[0] = $picx - 1 then return 1
    ElseIf $pixel[1] = $picy - 1 then return 2
    ElseIf $pixel[1] = $picy + 21 then return 3
    ElseIf $pixel[0] = $picx + 11 then return 4
    Endif
EndFunc;==>_CollisionDetect

Havn't tested it cause im at school but should work...
