love.graphics.newParticleSystem

Creates a new ParticleSystem.

This function can be slow if it is called repeatedly, such as from love.update or love.draw. If you need to use a specific resource often, create it once and store it somewhere it can be reused!

	psystem:setSizeVariation(1)
	psystem:setLinearAcceleration(-20, -20, 20, 20) -- Random movement in all directions.
	psystem:setColors(255, 255, 255, 255, 255, 255, 255, 0) -- Fade to transparency.
