Method Rebind

trinity/Particle/Tr2DynamicEmitter.cpp:229–257

-------------------------------------------------------------------------------------- Description: Re-binds the emitter to its particle system. Tries to bind each generator to the corresponding element. IsValid can be checked after Rebind to see if the binding succeeded. --------------------------------------------------------------------------------------
