Particle
Size Over Lifetime Module
SizeOverLifetimeModule is a subclass of ParticleGeneratorModule used to handle size changes over the lifetime of a particle system.
Properties
| Property | Description |
|---|---|
| separateAxes | Boolean value specifying whether the size changes independently for each axis |
| sizeX | ParticleCompositeCurve object representing the size change curve along the x-axis |
| sizeY | ParticleCompositeCurve object representing the size change curve along the y-axis |
| sizeZ | ParticleCompositeCurve object representing the size change curve along the z-axis |
| size | ParticleCompositeCurve object to get or set the size change curve of particles |
Polyline Editing
For the ParticleCompositeCurve object, a polyline editor is built into the editor for visual curve adjustments.
Or in code:
sizeOverLifetime.enabled = true;
sizeOverLifetime.size.mode = ParticleCurveMode.Curve;
const curve = sizeOverLifetime.size.curve;
const keys = curve.keys;
keys[0].value = 0.153;
keys[1].value = 1.0;
curve.addKey(0.057, 0.37);
curve.addKey(0.728, 0.958);
