Setcolormask problem

SetMaskColor(255, 0, 0) 
image:Timage = LoadAnimImage("Data/player.bmp",128,128,0,31)

I have this code...
The image I load has a red background (255,0,0) but somehow when I draw it it also draws the red part...
I don't get it... Is the mask and drawing affected by some functions? (my code is preety large so something there might cause that)

Have you remembered to use SetBlend MASKBLEND before you draw the image?

SetScale 1,1
SetColor 255, 255, 255
SetAlpha 1
SetBlend MASKBLEND
SetRotation 0
DrawImage image,x,y,frame

this is the code with the drawing

In addition, you say your code is large. What happens when you run a simple program such as :

graphics 800,600
setmaskcolor 255,0,0
local image:timage=loadanimimage("data/player.bmp",128,128,0,31)
drawimage image,100,100,0
flip
waitkey()

? (obviously adjust if you're using GL driver etc)?
Also try it with graphics 800,600,32 mode plus load the image into a 32bit image viewer and check the colour. I have been caught out thinking something is 255,0,0 when it was 250,5,5 (or similar).

the color 255,0,0 indeed but... in your example it still draw the red surround.
So I guess the problem is from the image... but the bmp are not supossed to have alpha informations?
Btw If I use png... I won't have to think about mask colors as the alpha value will take care of this right? (can they be generated in 3d max?)

Nevermind... I used GlueIt to put the frames next to each other and that messed up the alpha thing... now I used game maker (the only thing its good at) to do that and it works perfectly :)

local image:timage=loadanimimage("data/player.bmp",128,128,0,31)

that command is missing the flag for the Mask

setmaskcolor 255,0,255
loadanimimage("data/player.bmp",128,128,0,31,MASKEDIMAGE)

It isn't needed.

MASKEDIMAGE is included in the default AutoImageFlags (as is FILTEREDIMAGE).

It never was for me...

I always had to run the loadimage command like that..

Never 'was'? What about now?
