| ParticleSystem:setGravity | Sets the gravity affecting the particles (acceleration along the y-axis). |
| ParticleSystem:setImage | Sets the image to be used for the particles. |
| ParticleSystem:setInsertMode | Sets the mode to use when the ParticleSystem adds new particles. |
| ParticleSystem:setLifetime | Sets how long the particle system should emit particles (if -1 then it emits particles forever). |
| ParticleSystem:setLinearAcceleration | Sets the linear acceleration (acceleration along the x and y axes) for particles. |
| ParticleSystem:setLinearDamping | Sets the amount of linear damping (constant deceleration) for particles. |
| ParticleSystem:setOffset | Set the offset position which the particle sprite is rotated around. |
| ParticleSystem:setParticleLife | Sets the life of the particles. |
| ParticleSystem:setParticleLifetime | Sets the lifetime of the particles. |
| ParticleSystem:setPosition | Sets the position of the emitter. |
| ParticleSystem:setQuads | Sets a series of Quads to use for the particle sprites. |
| ParticleSystem:setRadialAcceleration | Set the radial acceleration (away from the emitter). |
| ParticleSystem:setRelativeRotation | Sets whether particle angles and rotations are relative to their velocities. |
| 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:setSizes | Sets the sizes of the particle over its lifetime. |
| 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:setTexture | Sets the texture (Image or Canvas) to be used for the particles. |
| 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. |
