Particle Effects

If you are a gamer and you've played the Xbox 360 you've probably played or at least heard of a game called geometry wars. That game has some insane particle effects!

More then half of the objects shown in this screenshot are particles. And it looks very cool in motion!

Well as some of you might know already, I'm working on a game called Wings of Apocalypse. A little over a month ago,Brian , one of the co-developers (3D Artist) on the project felt that the game looked too plain and we needed some particle effects. I agreed with him and a few thousand keyboard clicks later particle effects were born into my world!

Right now we're trying not to show much of what we've done just yet but heres a sneak peak at what the particle effects look like :).

And, for all the game coders out there, the following code shows how I define a particle. The code is based on Java's syntax but it shouldn't be too hard to translate it into other languages. If you're using C then you would have to convert this definition class to a 'struct', but if you're using C++ or C# you shoudn't have any trouble converting the code.
class Particle
String name;
boolean active; // Active (Yes/No)
float life; // Particle Life
float fade; // Fade Speed

float r; // Red Value
float g; // Green Value
float b; // Blue Value

float rd; // Red End Value
float gd; // Green End Value
float bd; // Blue End Value

float x; // X Position
float y; // Y Position
float z; // Z Position

float xi; // X Direction
float yi; // Y Direction
float zi; // Z Direction

float xg; // X Gravity
float yg; // Y Gravity
float zg; // Z Gravity

float slowdown=1.0f; // Slow Down Particles

float xspeed=0; // Base X Speed
float yspeed=0; // Base Y Speed

public Particle(String n)


Once you have your particle defined the only things left to do are to manipulate the variables used by the particle and then draw it. Of course its not THAT easy, but its not hard either. I'm too lazy right now to try to explain my particle system algorithms but most of it is basic physics. And, you can find algorithms all over the web lol...
