CPUParticles2D

Inherits: Node2D < CanvasItem < Node < Object

A CPU-based 2D particle emitter.

Description

CPU-based 2D particle node used to create a variety of particle systems and effects.

See also GPUParticles2D, 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.

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_VELOCITY = 1

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

Parameter PARAM_ORBIT_VELOCITY = 2

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

Parameter PARAM_LINEAR_ACCEL = 3

Use with set_param_min, set_param_max, and set_param_curve to set linear acceleration properties.

Parameter PARAM_RADIAL_ACCEL = 4

Use with set_param_min, set_param_max, and set_param_curve to set radial acceleration properties.

Parameter PARAM_TANGENTIAL_ACCEL = 5

Use with set_param_min,
