Bases: unreal.Object

Particle Emitter

C++ Source:

  • Module: Engine

  • File: ParticleEmitter.h

Editor Properties: (see get_editor_property/set_editor_property)

  • collapsed (bool): [Read-Write] This value indicates the emitter should be drawn ‘collapsed’ in Cascade

  • detail_mode_bitmask (uint32): [Read-Write] Detail mode: Set flags reflecting which system detail mode you want the emitter to be ticked and rendered in

  • detail_mode_display (str): [Read-Only] Detail Mode Display

  • disable_when_insignficant (bool): [Read-Write] When true, emitters deemed insignificant will have their tick and render disabled Instantly. When false they will simple stop spawning new particles.

  • disabled_lo_ds_keep_emitter_alive (bool): [Read-Write] When true, if the current LOD is disabled the emitter will be kept alive. Otherwise, the emitter will be considered complete if the current LOD is disabled.

  • emitter_editor_color (Color): [Read-Write] The color of the emitter in the curve editor and debug rendering modes.

  • emitter_name (Name): [Read-Write] The name of the emitter.

  • emitter_render_mode (EmitterRenderMode): [Read-Write] How to render the emitter particles. Can be one of the following:

    ERM_Normal - As the intended sprite/mesh ERM_Point - As a 2x2 pixel block with no scaling and the color set in EmitterEditorColor ERM_Cross - As a cross of lines, scaled to the size of the particle in EmitterEditorColor ERM_None - Do not render

  • initial_allocation_count (int32): [Read-Write] Initial allocation count - overrides calculated peak count if > 0

  • quality_level_spawn_rate_scale (float): [Read-Write] Quality Level Spawn Rate Scale

  • significance_level (ParticleSignificanceLevel): [Read-Write] The significance level required of this emitter’s owner for this emitter to be active.

  • use_legacy_spawning_behavior (bool): [Read-Write] If true, maintains some legacy spawning behavior.
