in the screenshot, there are trails of smoke, coming from some of the projectiles. if you downöoad and try the game, wich is absolutely excellent by the way. You will see it clearer.
I want to figure out how they make those trails, particles, alpha blended comes to mind, kind of what I am doing, only, HOW do you make the particles look like that?
any ideas please?
the game is freeware so don''t worry.

You can try blending...
drawing the missle/missle smoke over and over again... with the alpha starting out at zero, and going to 100 when you reach your missle...
I think thats the technique your looking for...

They use textured strips, not particles, to create a trail.
basically, you ''drop'' points behind some object as it travels through space, then you create a tri-strip between the points of some width. Like this:
+...+...+...+ (object) traveling -->
Where the + are the points along the strip & the ''.'' are the space between the point samples.
To build a tri-strip from this:
|---|---|---|
+.\.+.\.+.\.+ (object) traveling -->
|---|---|---|
where the |,-, & \ are the lines of the tri-strip.

Sorry to *BUMP* my own message, but I just want to know if anyone can help me figure out how to do this in DirectDraw 2D
The tri strip is very clear to see when you are aware of it, and are really looking. How could I achieve it in 2D? I am quite sure there isn''t any hardware method.
Modifying a breshenham line algorithm comes to mind, but modifying it how? any help?
thanks.
