Finally, AddObjectInstanceVarParam had been released.

I found that AddObjectInstanceVarParam had been released at multiplayer plugin. It might allow 3rd plugin to control the instance variable directly, cool~

Yaaay! Even though I understand nothing about plugins and how they work, I am sure this is big news if rex decided to share his thoughts

Yes, this is a new parameter type we added for Multiplayer, but other plugins can use it. It must come after an ordinary object parameter. Then when the user picks an object from the object parameter, the "object instance var" parameter lists all instance variables for that object. The instance variable index is passed at runtime.
