I'm in an intro game programming class, and I decided to make a game based off a popular game called Geometry Wars in Java2D (professor decided to use it). I'm at a point where I've created a decent game, but with very simple graphics (simple circles, rectangles, solid colors, etc). I have about 0 experience in graphics programming (although quite a bit in other kinds of programming), but I want my game to have a "polished" look.
Specifically I would like to know:
- How to create a glow effect
- Give moving shapes/lines a "trail"
- Do them efficiently
I'm getting a lot of inspiration from this game: http://www.youtube.com/watch?v=y-_qlaywKBs
I especially like the explosions and I've implemented a similar effect in my game which basically paints a bunch of white spheres. So for instance, how could I paint them (as efficiently as possible without too much trouble) to both glow and have the cool trail? Of course I would extend the technique to other things in my game.
And thanks for help in advance. Sorry I'm such a newbie, but I'm really enjoying what I've been learning so far.
