ParticleSystem

Used to create cool effects, like fire. The particle systems are created and drawn on the screen using functions in love.graphics. They also need to be updated in the update(dt) callback for you to see any changes in the particles emitted.

Constructors

love.graphics.newParticleSystem

Creates a new ParticleSystem.

Functions

Object:type	Gets the type of the object as a string.
Object:typeOf	Checks whether an object is of a certain type.
ParticleSystem:count	Gets the amount of particles that are currently in the system.
ParticleSystem:getDirection	Gets the direction of the particle emitter (in radians).
ParticleSystem:getEmissionRate	Gets the amount of particles emitted per second.
ParticleSystem:getOffsetX	Get the x coordinate of the particle rotation offset.
ParticleSystem:getOffsetY	Get the y coordinate of the particle rotation offset.
ParticleSystem:getPosition	Gets the position of the emitter.
ParticleSystem:getSpread	Gets the amount of directional spread of the particle emitter (in radians).
ParticleSystem:getX	Gets the x-coordinate of the particle emitter's position.
ParticleSystem:getY	Gets the y-coordinate of the particle emitter's position.
ParticleSystem:isActive	Checks whether the particle system is actively emitting particles.
ParticleSystem:isEmpty	Checks whether the particle system is empty of particles.
ParticleSystem:isFull	Checks whether the particle system is full of particles.
ParticleSystem:pause	Pauses the particle emitter.
ParticleSystem:reset	Resets the particle emitter, removing existing particles and resetting the lifetime counter.
ParticleSystem:setBufferSize	Sets the size of the buffer (the max allowed amount of particles in the system).
ParticleSystem:setColor	Sets the color of the image.
ParticleSystem:setDirection	Sets the direction the particles will be emitted in.
ParticleSystem:setEmissionRate	Sets the amount of particles emitted per second.
ParticleSystem:setGravity	Sets the gravity affecting the particles (acceleration along the y-axis).
ParticleSystem:setLifetime	Sets how long the particle system should emit particles (if -1 then it emits particles forever).
ParticleSystem:setOffset	Set the offset position which the particle sprite is rotated around.
ParticleSystem:setParticleLife	Sets the life of the particles.
ParticleSystem:setPosition	Sets the position of the emitter.
ParticleSystem:setRadialAcceleration	Set the radial acceleration (away from the emitter).
ParticleSystem:setRotation	Sets the rotation of the image upon particle creation (in radians).
ParticleSystem:setSize	Sets the size of the particle (1.0 being normal size).
ParticleSystem:setSizeVariation	Sets the amount of size variation.
ParticleSystem:setSpeed	Sets the speed of the particles.
ParticleSystem:setSpin	Sets the spin of the sprite.
ParticleSystem:setSpinVariation	Sets the amount of spin variation.
ParticleSystem:setSpread	Sets the amount of spread for the system.
ParticleSystem:setSprite	Sets the image which is to be emitted.
ParticleSystem:setTangentialAcceleration	Sets the tangential acceleration (acceleration perpendicular to the particle's direction).
ParticleSystem:start	Starts the particle emitter.
ParticleSystem:stop	Stops the particle emitter, resetting the lifetime counter.
ParticleSystem:update	Updates the particle system; moving, creating and killing particles.
