3D particle emitter. 3D particle node used to create a variety of particle systems and effects. [code]Particles[/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. Number of particles to emit. Particle draw order. Uses [code]DRAW_ORDER_*[/code] values. Default value: [code]DRAW_ORDER_INDEX[/code]. If [code]true[/code] particles are being emitted. Default value: [code]true[/code]. Time ratio between each emission. If [code]0[/code] particles are emitted continuously. If [code]1[/code] all particles are emitted simultaneously. Default value: [code]0[/code]. Amount of time each particle will exist. Default value: [code]1[/code]. If [code]true[/code] particles use the parent node's coordinate space. If [code]false[/code] they use global coordinates. Default value: [code]true[/code]. If [code]true[/code] only [code]amount[/code] particles will be emitted. Default value: [code]false[/code]. [Material] for processing particles. Can be a [ParticlesMaterial] or a [ShaderMaterial]. Emission randomness ratio. Default value: [code]0[/code]. Speed scaling ratio. Default value: [code]1[/code]. Particles are drawn in the order emitted. Particles are drawn in order of remaining lifetime. Particles are drawn in order of depth.
