SPRCOLL does not work on PocketPC

[AndyH]

Hi, SPRCOLL does not work on Pocket PC.  Not been able to test with any other platform (eg: Mac, GP2X, Linux etc) but the following code works in Windows, but not on the Pocket PC:

Code: (glbasic) [Select]

SETSCREEN 320,240,0
LIMITFPS 60

GLOBAL mx,my,ma,mb

BLACKSCREEN
DRAWRECT 0,0,16,16, RGB(255,255,255)

GRABSPRITE 0,0,0,16,16
GRABSPRITE 1,0,0,8,8

WHILE TRUE

MOUSESTATE mx,my,ma,mb

DRAWSPRITE 0, 160,120
DRAWSPRITE 1, mx,my

IF SPRCOLL( 0,160,120, 1,mx,my )
PRINT "COLLISION!!!",0,0
ELSE
PRINT "OK",0,0
ENDIF

SHOWSCREEN
WENDMove the mouse to position the smaller square (used squares just for this example, in my code I have also tried LOADSPRITE with same results).  On Windows when any part of a pixel in sprite 1 and 2 overlap, the COLLISSION!!! message appears, otherwise OK.  On the Pocket PC COLLISION!!! will never appear.

Yikes!

It was a problem with transparency. You image was fully non-transparent. Then the colorkey color was plain white. Since your image was white only, you got no hit.
Make it green to work
Fixed in next update.

Thanks Gernot.  BTW - the mask I'd used in the PNG of my game was white too - DOH!  Good to know it will work in the next update though so I won't change to green for now.  Also, once the ANIMCOLL type command is available I won't need to use generic masks anyway
