emitting

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.

Instance members

var amount: Int32
Number of particles emitted in one emission cycle.
var angleCurve: Curve?
Each particle’s rotation will be animated along this Curve.
var angleMax: Double
Maximum initial rotation applied to each particle, in degrees.
var angleMin: Double
Minimum equivalent of angleMax.
var angularVelocityCurve: Curve?
Each particle’s angular velocity will vary along this Curve.
var angularVelocityMax: Double
Maximum initial angular velocity (rotation speed) applied to each particle in degrees per second.
var angularVelocityMin: Double
Minimum equivalent of angularVelocityMax.
var animOffsetCurve: Curve?
Each particle’s animation offset will vary along this Curve.
var animOffsetMax: Double
Maximum animation offset that corresponds to frame index in the texture. 0 is the first frame, 1 is the last one. See particlesAnimation.
var animOffsetMin: Double
Minimum equivalent of animOffsetMax.
var animSpeedCurve: Curve?
Each particle’s animation speed will vary along this Curve.
var animSpeedMax: Double
Maximum particle animation speed. Animation speed of 1 means that the particles will make full 0 to 1 offset cycle during lifetime, 2 means 2 cycles etc.
var animSpeedMin: Double
Minimum equivalent of animSpeedMax.
var color: Color
Each particle’s initial color. If texture is defined, it will be multiplied by this 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 Gradient (multiplied with color).
var dampingCurve: Curve?
Damping will vary along this Curve.
var dampingMax: Double
The maximum rate at which particles lose velocity. For example value of 100 means that the particle will go from 100 velocity to 0 in 1 second.
var dampingMin: Double
Minimum equivalent of dampingMax.
var direction: Vector2
Unit vector specifying the particles’ emission direction.
var drawOrder: CPUParticles2D.DrawOrder
Particle draw order. Uses DrawOrder values.
var emissionColors: PackedColorArray
Sets the Colors to modulate particles by when using .points or .directedPoints.
var emissionNormals: PackedVector2Array
Sets the direction the particles will be emitted in when using .directedPoints.
var emissionPoints: PackedVector2Array
Sets the initial positions to spawn particles when using .points or .directedPoints.
var emissionRectExtents: Vector2
The rectangle’s extents if emissionShape is set to .rectangle.
var emissionShape: CPUParticles2D.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 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 simulation of the particle system itself.
var fractDelta: Bool
If true, results in fractional delta calculation which has a smoother particles display effect.
var gravity: Vector2
Gravity applied to every particle.
var hueVariationCurve: Curve?
Each particle’s hue will vary along this Curve.
var hueVariationMax: Double
Maximum initial hue variation applied to each particle. It will shift the particle color’s hue.
var hueVariationMin: Double
Minimum equivalent of hueVariationMax.
var initialVelocityMax: Double
Maximum initial velocity magnitude for each particle. Direction comes from direction and spread.
var initialVelocityMin: Double
Minimum equivalent of initialVelocityMax.
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 applied to each particle in the direction of motion.
var linearAccelMin: Double
Minimum equivalent of linearAccelMax.
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 CPUParticles2D node (and its parents) when it is moved or rotated. If false, particles use global coordinates; they will not move or rotate along the CPUParticles2D node (and its parents) when it is moved or rotated.
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 orbital velocity applied to each particle. Makes the particles circle around origin. Specified in number of full rotations around origin per second.
var orbitVelocityMin: Double
Minimum equivalent of orbitVelocityMax.
var particleFlagAlignY: Bool
Align Y axis of particle with the direction of its velocity.
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 applied to each particle. Makes particle accelerate away from the origin or towards it if negative.
var radialAccelMin: Double
Minimum equivalent of radialAccelMax.
var randomness: Double
Emission lifetime randomness ratio.
var scaleAmountCurve: Curve?
Each particle’s scale will vary along this Curve.
var scaleAmountMax: Double
Maximum initial scale applied to each particle.
var scaleAmountMin: Double
Minimum equivalent of scaleAmountMax.

var spread: Double
Each particle’s initial direction range from +spread to -spread degrees.
var tangentialAccelCurve: Curve?
Each particle’s tangential acceleration will vary along this Curve.
var tangentialAccelMax: Double
Maximum tangential acceleration applied to each particle. Tangential acceleration is perpendicular to the particle’s velocity giving the particles a swirling motion.
var tangentialAccelMin: Double
Minimum equivalent of tangentialAccelMax.
var texture: Texture2D?
Particle texture. If null, particles will be squares.
func convertFromParticles(Node?)
Sets this node’s properties to match a given GPUParticles2D node with an assigned ParticleProcessMaterial.
