2020-03-30 18:22:57 +02:00
ParticlesMaterial defines particle properties and behavior. It is used in the [code]process_material[/code] of [GPUParticles3D] and [GPUParticles2D] emitter nodes.
2017-10-03 21:30:32 +02:00
Some of this material's properties are applied to each particle when emitted, while others can have a [CurveTexture] applied to vary values over the lifetime of the particle.
2021-11-30 22:32:23 +01:00
Particle animation is available only in [GPUParticles2D]. To use it, attach a [CanvasItemMaterial], with [member CanvasItemMaterial.particles_animation] enabled, to the particles node.

With animation speed greater than [code]1[/code], remember to enable [member CanvasItemMaterial.particles_anim_loop] property if you want the animation to repeat.

Particle lifetime randomness ratio. The lifetime will be multiplied by a value interpolated between [code]1.0[/code] and a random number less than one. For example a random ratio of [code]0.4[/code] would scale the original lifetime between [code]0.4-1.0[/code] of its original value.
