2D particle emitter. 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. Returns the amount of particles spawned at each emission Gets the amount of seconds that each particle will be visible. Returns the texture for emitted particles Returns whether this emitter is currently emitting or not Sets the amount of particles spawned at each emission If this is set to true then the particle emitter will emit particles, if its false it will not. Sets the amount of seconds that each particle will be visible. 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]. Number of horizontal frames in [code]texture[/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]. Particle texture. If [code]null[/code] particles will be squares. Number of vertical frames in [code]texture[/code]. Particles are drawn in the order emitted. Particles are drawn in order of remaining lifetime.
