Each particle’s angular velocity (rotation speed) will vary along this Curve over its lifetime.
var angularVelocityMax: Double
Maximum initial angular velocity (rotation speed) applied to each particle in degrees per second.
var angularVelocityMin: Double
Minimum initial angular velocity (rotation speed) applied to each particle in degrees per second.
var animOffsetCurve: Curve?
Each particle’s animation offset will vary along this Curve.
var animOffsetMax: Double
Maximum animation offset.
var animOffsetMin: Double
Minimum animation offset.
var animSpeedCurve: Curve?
Each particle’s animation speed will vary along this Curve.
var animSpeedMax: Double
Maximum particle animation speed.
var animSpeedMin: Double
Minimum particle animation speed.
var color: Color
Each particle’s initial color.
var colorInitialRamp: Gradient?
Each particle’s initial color will vary along this GradientTexture1D (multiplied with color).
var colorRamp: Gradient?
Each particle’s color will vary along this GradientTexture1D over its lifetime (multiplied with color).
var dampingCurve: Curve?
Damping will vary along this Curve.
var dampingMax: Double
Maximum damping.
var dampingMin: Double
Minimum damping.
var drawOrder: CPUParticles3D.DrawOrder
Particle draw order. Uses DrawOrder values.
var emissionBoxExtents: Vector3
The rectangle’s extents if emissionShape is set to .box.
var emissionColors: PackedColorArray
Sets the Colors to modulate particles by when using .points or .directedPoints.
var emissionNormals: PackedVector3Array
Sets the direction the particles will be emitted in when using .directedPoints.
var emissionPoints: PackedVector3Array
Sets the initial positions to spawn particles when using .points or .directedPoints.
var emissionRingAxis: Vector3
The axis of the ring when using the emitter .ring.
var emissionRingHeight: Double
The height of the ring when using the emitter .ring.
var emissionRingInnerRadius: Double
The inner radius of the ring when using the emitter .ring.
var emissionRingRadius: Double
The radius of the ring when using the emitter .ring.
var emissionShape: CPUParticles3D.EmissionShape
Particles will be emitted inside this region. See EmissionShape for possible values.
var emissionSphereRadius: Double
The sphere’s radius if EmissionShape is set to .sphere.
var emitting: Bool
If true, particles are being emitted. emitting can be used to start and stop particles from emitting. However, if oneShot is true setting emitting to true will not restart the emission cycle until after all active particles finish processing. You can use the [signal finished] signal to be notified once all active particles finish processing.
var explosiveness: Double
How rapidly particles in an emission cycle are emitted. If greater than 0, there will be a gap in emissions before the next cycle begins.
var finished: SimpleSignal
Emitted when all active particles have finished processing. When oneShot is disabled, particles will process continuously, so this is never emitted.
var fixedFps: Int32
The particle system’s frame rate is fixed to a value. For example, changing the value to 2 will make the particles render at 2 frames per second. Note this does not slow down the particle system itself.
var flatness: Double
Amount of spread in Y/Z plane. A value of 1 restricts particles to X/Z plane.
var fractDelta: Bool
If true, results in fractional delta calculation which has a smoother particles display effect.
var gravity: Vector3
Gravity applied to every particle.
var hueVariationCurve: Curve?
Each particle’s hue will vary along this Curve.
var hueVariationMax: Double
Maximum hue variation.
var hueVariationMin: Double
Minimum hue variation.
var initialVelocityMax: Double
Maximum value of the initial velocity.
var initialVelocityMin: Double
Minimum value of the initial velocity.
var lifetime: Double
Amount of time each particle will exist.
var lifetimeRandomness: Double
Particle lifetime randomness ratio.
var linearAccelCurve: Curve?
Each particle’s linear acceleration will vary along this Curve.
var linearAccelMax: Double
Maximum linear acceleration.
var linearAccelMin: Double
Minimum linear acceleration.
var localCoords: Bool
If true, particles use the parent node’s coordinate space (known as local coordinates). This will cause particles to move and rotate along the CPUParticles3D node (and its parents) when it is moved or rotated. If false, particles use global coordinates; they will not move or rotate along the CPUParticles3D node (and its parents) when it is moved or rotated.
var mesh: Mesh?
The Mesh used for each particle. If null, particles will be spheres.
var oneShot: Bool
If true, only one emission cycle occurs. If set true during a cycle, emission will stop at the cycle’s end.
var orbitVelocityCurve: Curve?
Each particle’s orbital velocity will vary along this Curve.
var orbitVelocityMax: Double
Maximum orbit velocity.
var orbitVelocityMin: Double
Minimum orbit velocity.
var particleFlagAlignY: Bool
Align Y axis of particle with the direction of its velocity.
var particleFlagDisableZ: Bool
If true, particles will not move on the Z axis.
var particleFlagRotateY: Bool
If true, particles rotate around Y axis by angleMin.
var preprocess: Double
Particle system starts as if it had already run for this many seconds.
var radialAccelCurve: Curve?
Each particle’s radial acceleration will vary along this Curve.
var radialAccelMax: Double
Maximum radial acceleration.
