Notes for SimpleParticleSystem:
-
float3 pos
Origon point for your particle system. -
AtlasedTexture texture
Texture for the particles, defined in resources.tdf. -
float3 emitVector
Use DIR to have it acquire a direction, this will utilize a poly on your object that you choose as an emitter. See my notes on vectors to understand how to use the vectors of this: i.e. 0,1,0 is straight up -
CColorMap colorMap
This will give your system a range of colors spread over time, it has 4 parts: RED, GREEN, BLUE, ALPHA one note: For additive blend use values that are low like: 0.1 or 0.05 For overlay use 1.0 see notes on overlay versus additive blend. -
float3 gravity
Vector force applied to the particles every frame. -
float airdrag
Constant multiplier on the particle each frame, a value of 1.0 means the particles will keep their current momentum, a value bellow 1 and they will slow down each frame. -
float particleLife
Life of the particles in frames. -
float particleLifeSpread
Random number between 0 and particleLifeSpread added to particleLife. -
int numParticles
Number of particles that will be spawned. -
float particleSpeed
Initial speed of the particles. -
float particleSpeedSpread
Random number between 0 and particleSpeedSpread added to particleSpeed. -
float particleSize
Size of the particles. -
float particleSizeSpread
Random number between 0 and particleSizeSpread added to particleSize. -
float sizeGrowth
Size added to particles each frame. -
float sizeMod
Size frame multiplier. -
float emitRot
Rotation in degree from emitVector that particles will be spawned from, a value of 90 will emmit particles in a plane perpendicular to the emitVector. -
float emitRotSpread
Random number between 0 and emitRotSpread added to emitRot, a value of 180 will make the particles spawn in a full sphere. -
bool directional
If the particles should be oriented to point at the direction of their velocity.
Notes vectors:
- Vectors are directional systems represented by a 3d graph here: WORK IN PROGRESS!
- WORK IN PROGRESS!
