Don't mind the mess!
We're currently in the process of migrating the Panda3D Manual to a new service. This is a temporary layout in the meantime.
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.
|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.
|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]|
