ParticleSystem

A ParticleSystem can be used to create particle effects like fire or smoke.

The particle system has to be created using love.graphics.newParticleSystem. Just like any other Drawable it can be drawn to the screen using love.graphics.draw. You also have to update it in the update callback to see any changes in the particles emitted.

The particle system won't create any particles unless you call setParticleLifetime and setEmissionRate.

Constructors

love.graphics.newParticleSystem Creates a new ParticleSystem.
