/** \class plAGMasterMod |
|
A modifier which can apply animations to scene objects. |
|
Works together with a plAGModifier, which can apply animation to a |
|
single scene object. A master modifier hooks up to a family of |
|
ag modifiers to do its job. |
|
An animation (plAGAnim) can have many different channels, but the |
|
user can just pass it to a single master mod to apply it to all the |
|
channels owned by that master. The master will take care of hooking |
|
each channel up to an ag modifier. |
|
The goal is to make an animation a conceptually (and practically) simple |
|
object to work with, whether or not it has multiple channels. |
