panda3d.physics.ParticleSystem¶

class ParticleSystem¶

Bases: Physical

Contains and manages a particle system.

Inheritance diagram

__init__(copy: ParticleSystem) → None¶: Copy Constructor.

__init__(pool_size: int) → None¶: Default Constructor.

setPoolSize(size: int) → None¶: accessqueries

setBirthRate(new_br: float) → None¶

setSoftBirthRate(new_br: float) → None¶

setLitterSize(new_ls: int) → None¶

setLitterSpread(new_ls: int) → None¶

setLocalVelocityFlag(lv: bool) → None¶

setSystemGrowsOlderFlag(sgo: bool) → None¶

setSystemLifespan(sl: float) → None¶

setSystemAge(age: float) → None¶

setActiveSystemFlag(a: bool) → None¶

setSpawnOnDeathFlag(sod: bool) → None¶

setSpawnRenderNode(node: PandaNode) → None¶

setSpawnRenderNodePath(node: NodePath) → None¶

setTemplateSystemFlag(tsf: bool) → None¶

setRenderParent(node: NodePath) → None¶

setRenderParent(node: PandaNode) → None¶

setRenderer(r: BaseParticleRenderer) → None¶

setEmitter(e: BaseParticleEmitter) → None¶

setFactory(f: BaseParticleFactory) → None¶

setFloorZ(z: float) → None¶

clearFloorZ() → None¶

getPoolSize() → int¶

getBirthRate() → float¶

getSoftBirthRate() → float¶

getLitterSize() → int¶

getLitterSpread() → int¶

getLocalVelocityFlag() → bool¶

getSystemGrowsOlderFlag() → bool¶

getSystemLifespan() → float¶

getSystemAge() → float¶

getActiveSystemFlag() → bool¶

getSpawnOnDeathFlag() → bool¶

getSpawnRenderNode() → PandaNode¶

Return type: PandaNode

getSpawnRenderNodePath() → NodePath¶

Return type: NodePath

getIWasSpawnedFlag() → bool¶

getLivingParticles() → int¶

getRenderParent() → NodePath¶

Return type: NodePath

getRenderer() → BaseParticleRenderer¶

Return type: BaseParticleRenderer

getEmitter() → BaseParticleEmitter¶

Return type: BaseParticleEmitter

getFactory() → BaseParticleFactory¶

Return type: BaseParticleFactory

getFloorZ() → float¶

getTicsSinceBirth() → float¶

addSpawnTemplate(ps: ParticleSystem) → None¶

clearSpawnTemplates() → None¶

render() → None¶: Populates an attached GeomNode structure with the particle geometry for rendering. This is a wrapper for accessability.

induceLabor() → None¶: Forces the birth of a particle litter this frame by resetting _tics_since_birth

clearToInitial() → None¶: Resets the system to its start state by resizing to 0, then resizing back to current size.

softStop(br: float) → None¶: Causes system to use birth rate set by setSoftBirthRate()

softStart(br: float) → None¶: Causes system to use birth rate set by setBirthRate()

softStart(br: float, first_birth_delay: float) → None¶: Causes system to use birth rate set by setBirthRate(), with the system’s first birth being delayed by the value of first_birth_delay. Note that a negative delay is perfectly valid, causing the first birth to happen sooner rather than later.

update(dt: float) → None¶

writeFreeParticleFifo(out: ostream, indent: int) → None¶: Write a string representation of this instance to <out>.

writeSpawnTemplates(out: ostream, indent: int) → None¶: Write a string representation of this instance to <out>.

static getClassType() → TypeHandle¶

Return type: TypeHandle
