CPUParticles3D¶

Inherits: GeometryInstance3D < VisualInstance3D < Node3D < Node < Object

A CPU-based 3D particle emitter.

Description¶

CPU-based 3D particle node used to create a variety of particle systems and effects.

See also GPUParticles3D, which provides the same functionality with hardware acceleration, but may not run on older devices.

Signals¶

finished ( )

Emitted when all active particles have finished processing. When one_shot is disabled, particles will process continuously, so this is never emitted.

Enumerations¶

enum DrawOrder:

DrawOrder DRAW_ORDER_INDEX = 0

Particles are drawn in the order emitted.

DrawOrder DRAW_ORDER_LIFETIME = 1

Particles are drawn in order of remaining lifetime. In other words, the particle with the highest lifetime is drawn at the front.

DrawOrder DRAW_ORDER_VIEW_DEPTH = 2

Particles are drawn in order of depth.

enum Parameter:

Parameter PARAM_INITIAL_LINEAR_VELOCITY = 0

Use with set_param_min, set_param_max, and set_param_curve to set initial velocity properties.

Parameter PARAM_ANGULAR_
