Do you work With DirecX3D ?

How do you draw the Square?

Where do you want to have the AlphaBlend - Transperency?

[ThePentiumGuy]

Dev.RenderState.AlphaSourceBlend = Blend.SourceAlpha

Dev.RenderState.AlphaDestinationBlend = Blend.InvSourceAlpha

DEv.RenderState.AlphaBlendEnable = True

in your render sub,

 

and then when loading your texture,

 

text = new texture(yourbitmap, width,height...,transparent color [see Intellisense])

 

sorry i dont remember of the top of my head

does that help,

pent?

 

edit:

does that help?
