So, first of all it is necessary to create an attribute for an emitter which will then be applied to a particle:
| Code Block | ||||||
|---|---|---|---|---|---|---|
| ||||||
# Write this part to SimulationPre
emitter = scene.getEmitter("Circle01")
emitter.createParticlesAttribute(100, PARTICLE_ATTR_TYPE_DOUBLE)
emitter.createParticlesAttribute(101, PARTICLE_ATTR_TYPE_INT)
emitter.createParticlesAttribute(102, PARTICLE_ATTR_TYPE_BOOL)
emitter.createParticlesAttribute(103, PARTICLE_ATTR_TYPE_VECTOR)
# Write this part to FramePre
emitter = scene.get_PB_Emitter("Circle01")
particleList = emitter.getParticles()
for particle in particleList:
particle.setAttribute(100, 3.14159)
particle.setAttribute(101, 5)
particle.setAttribute(102, True)
particle.setAttribute(103, Vector.new(1.0,0.0,1.0)) |
...
To request an attribute, simply use the following construction:
...
| Code Block | ||||||
|---|---|---|---|---|---|---|
| ||||||
for particle in particleList:
pi = particle.getAttribute(100)
scene.message(str(pi)) |
...
You can also remove an emitter’s ability to carry attributes with a destructor. Please note that this is not possible for single particles, but for certain attributes:
...
| Code Block | ||||||
|---|---|---|---|---|---|---|
| ||||||
frame = scene.getCurrentFrame()
if (frame == 50):
emitter.destroyParticlesAttribute(102) |
