I have imported a bb game into bmax and am having trouble understanding all the SetBlend/SetMaskColor/CreateImage/GrabImage command settings required to get my code to work. In B3D, I loaded a bmp and then grabbed each tile, setting the mask color each time:
Function TilesLoad()
Local Palette%
Local TileW%
Local k%
Palette%=LoadImage("Palette.tmp")
If Palette%<>0 Then
CurrentBuffer%=GraphicsBuffer()
SetBuffer ImageBuffer(Palette%)
TileW%=TileSize%-1
For k%=0 To MaxTiles%-1
Tiles%(k%+1)=CreateImage(TileW%,TileW%)
GrabImage Tiles%(k%+1),k%*TileW%,0
MaskImage Tiles%(k%+1),192,192,255
Next
SetBuffer CurrentBuffer%
FreeImage Palette%
EndIf
End Function
In bmax, I tried the following:
Function TilesLoad()
Local Palette:TImage
Local TileW%
Local k%
SetMaskColor 1,1,1 ' I seem to need this or bmax alphablends any black areas when I DrawImage to the BackBuffer despite SOLIDBLEND...
Palette=LoadImage("Palette.tmp")
If Palette<>Null Then
Cls
SetColor 255,255,255
SetBlend SOLIDBLEND
DrawImage Palette,0,0
SetBlend ALPHABLEND
TileW%=TileSize%-1
SetMaskColor 192,192,255
For k%=0 To MaxTiles%-1
Tiles:TImage[k%+1]=CreateImage(TileW%,TileW%,DYNAMICIMAGE|MASKEDIMAGE)
GrabImage Tiles[k%+1],k%*TileW%,0
Next
Palette=Null
GCCollect
EndIf
End Function
but the mask color is ignored later when I DrawImage the grabbed Tiles[]. I am evidently making a very basic error - probably due to my lack of understanding as to how all these commands integrate with each other - so if anyone can tell me what I am going wrong I would be very grateful!!
