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.
