Particle Factories

There are two types of particle factories, Point and ZSpin. The particle panel shows a third, Oriented, but this factory does not currently work. The differences between these factories lie in the orientation and rotational abilities. First, there are some common variables to the factories.

Variable	Definition	Values
lifespanBase	Average lifespan in seconds	[0, infinity)
lifespanSpread	Variation in lifespan	[0, infinity)
massBase	Average particle mass	[0, infinity)
massSpread	Variation in particle mass	[0, infinity)
terminalVelocityBase	Average particle terminal velocity	[0, infinity)
terminalVelocitySpread	Variation in terminal velocity	[0, infinity)

Point particle factories generate simple particles. They have no additional parameters. ZSpin particle factories generate particles that spin around the Z axis, the vertical axis in Panda3D. They have some additional parameters.

Variable	Definition	Values
initialAngle	Starting angle in degrees	[0, 360]
initialAngleSpread	Spread of initial angle	[0, 360]
finalAngle	Final angle in degrees	[0, 360]
fnalAngleSpread	Spread of final angle	[0, 360]
