java and games

Oh and another question.
Anybody got a short tutorial on alphablending with java.

Depends on the type of game.

No, no, no, no, no!!

The java.awt.Graphics object is SLOW, I mean way too slow.
Graphics2d is also way too slow.

You better write your own Graphics class, based on the java.awt.image.memoryImageSource or java.awt.image.BufferedImage class.

(however, if you just make a simple 2D game, or you wish to draw clipped concave polygons, java.awt.Graphics will do fine).

You can afphablend with Graphics2d. Use the constructor for color:
Color someAlphaColor=new Color(int red, int green, int blue, int alpha);
Graphics2d.setColor(someAlphaColor);

Koroljov: Thank you so much Koroljov. Thats what I needed to know.

Hm it doesnt seem to be working. I need somehting like a color key to make my sprites usable.

If you don''t need Graphics2D-object don''t use it, it ain''t any faster than Graphics.

Considered using OpenGL? It nicely handles things like rotation, scaling and alpha blending of your sprites.

btw. Most of the Java2D stuff is getting hardware-accelerated by the release of 1.5.

Oh and here''s a nice color tutorial:

Sure I''ve used OpenGL before. But consider my original post, I just switched to learning java. Now I didn''t know Opengl can be used with java. Nevertheless even if it can I''d prefer to do java wihout it first.
I think i''m not being clear as to what I want. I dont want blending or fading techniques. I want to be able to have sprites on a background. So basically say I have an image of a man with a white backround, then the white background has to be cut away.
With C/C++ DirectX8 I did this by using tga''s as textures and then alphablending. Earlier with DirectDraw I used ColorKeys. What I can use in java to achieve the desired effect?

Huh, seems saving the gif with transparency does it for java.
Thanks anyway for all the lins they''ll come in handy as well.
