Particle
Emission Module
EmissionModule is the emission module of ParticleGeneratorModule. This module is used to handle the emission behavior of the particle system, including particle emission rate, emission shape, and burst behavior.
Properties
| Property | Description |
|---|---|
| rateOverTime | This is a ParticleCompositeCurve object, representing the particle emission rate. The default value is 10. |
| rateOverDistance | This is a ParticleCompositeCurve object, representing the particle distance emission rate. The default value is 0. |
| shape | This is a BaseShape object, representing the shape of the emitter. |
Methods
| Method | Description |
|---|---|
| addBurst(burst: Burst) | Add a burst behavior |
| removeBurst(burst: Burst) | Remove a burst behavior |
| removeBurstByIndex(index: number) | Remove a burst behavior by index |
| clearBurst() | Clear all burst behaviors |
Shapes
Currently, the engine has the following built-in emitter shapes, providing corresponding shape auxiliary displays when the particle component is selected.
| Emitter Shape Type | Description |
|---|---|
| BoxShape | BaseShape object, emitter shape is a cube |
| CircleShape | BaseShape object, emitter shape is a circle |
| ConeShape | BaseShape object, emitter shape is a cone |
| HemisphereShape | BaseShape object, emitter shape is a hemisphere |
| SphereShape | BaseShape object, emitter shape is a sphere |
