Assigning Controllers
From Computing and Software Wiki
Controller can be assigned to any object through the C4 World Editor. This can be accomplished by selecting the object, most typically a geometry, through either of the view ports or the scene graph.
Goto Node->Info (or press Ctrl+C).
Select the Controller tab.
Highlight one of the available controllers on the left side under 'Controller type' .
If there are user editable settings, they will then become available under the 'Controller Settings' list.
By selecting OK, the controller will then be assigned to the object.
