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.

Functions
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:getOffsetX | Get the x coordinate of the particle rotation offset. |
ParticleSystem:getOffsetY | Get the y coordinate of the particle rotation offset. |
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 any 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 (color modulation needs to be activated for it to have any effect). |
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 degree of variation (0 meaning no variation and 1 meaning full variation between start and end). |
ParticleSystem:setSpeed | Sets the speed of the particles. |
ParticleSystem:setSpin | Sets the spin of the sprite. |
ParticleSystem:setSpinVariation | Sets the degree of variation (0 meaning no variation and 1 meaning full variation between start and end). |
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. |
Object:type | Gets the type of the object as a string. |
Object:typeOf | Checks whether an object is of a certain type. |
