Hi,

I need to resize (in fact scale) a 2D sprite. I know there's a way to do it by using the Sprite3D functions but using 3d functions causes a big slowdown (at least on my computer) so i want to know if anyone has come up with a way that uses only 2D commands ?

thanks in advance,

Hi,

I'm converting some C++ code to PB and, even though i have a little knowledge of C/C++, i have a doubt on the following lines :

Stack[StackTop++]=PrevPixel;

Thanks, that dit it

hDC = GetDC_(sprite_id)
color = GetPixel_(hDC,50,30)

Does someone ...

Greetings everyone,

My problem is as follows : i'm trying to convert a word variable to its big endian / Motorola value. I've been using this function (found on this forum :wink: ) :

Greetings,

floorTile.w[10000]
EndStructure


If I only ...
