Particle FactoriesΒΆ

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.

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.
