|
|
2D particle emitter.
|
|
</brief_description>
|
|
<description>
|
|
2D particle node used to create a variety of particle systems and effects. [code]Particles2D[/code] features an emitter that generates some number of particles at a given rate.
|
|
Use the [code]process_material[/code] property to add a [ParticlesMaterial] to configure particle appearance and behavior. Alternatively, you can add a [ShaderMaterial] which will be applied to all particles.
