DirectX Opacity
Author
Ok i want to make a splash screen for my program. Except i dont want to design a sprite that holds all the different frames for my opacity levels
My Game is in 2D and im loading up .png files
Im using Direct3D
I want to just loop through the opacity for my splash screen
i got this from some where but i cant understand the language http://activedeveloper.dk/weblogs/mrjs/archive/2005/09/14/1995.aspx
If you can help me or post a link to another tutorial
:)
Are you using the Sprite object to do your 2D drawing?
If so, then when you draw your sprite, you can supply a color (System.Drawing.Color) as one of the parameters. There is an alpha component to the color (see the System.Drawing.Color.FromARGB() function), which you can set to a number from 0 (completely transparent) to 255 (completely opaque).
So, you can adjust that alpha number over time to fade-in and fade-out a sprite.
I hope that's helpful.

Thats for the System lib
however i just found the answer got the idea from .FromARGB() ^
Didnt realize it had it in my code all along
D3Dsprite->Draw(sprite, ∂, ¢er, &position, D3DCOLOR_ARGB(255, 255, 255, 255));
^^^^The -> D3DCOLOR_ARGB(Opacity, Red, Green, Blue);
he he :)
