Hi,
This is actually something only used by the framework I created to port Vectrosity to PlayMaker, and this addProxy is something handled automatically under the hood.
What are you trying to achieve? do you want to create new custom actions for vectrosity?
You can add a proxy using the following code:
_line = VectorLine.SetLine(color.Value,time,_points);
VectrosityProxy.AddProxy(_line);
basically, this proxy allows me to create convenient custom action, without this, I can't reference a vector as is.
and to use this proxy, you can study the following custom action script: VectrositySetColor, where I expect the user to reference this proxy, so that I can set it's color.
bye,
Jean
