question

Attached is an updated version of the model from the original question, modified to use the Xbox Input code from the default Perspective View in the custom 3D Game View.

That game model was purposefully built with a minimal amount of extra stuff in it so that it is easier to understand. Adding Xbox Inputs adds more complexity to the code, as described below:

The things added to this version to make the xbox input work:

1. OnPreOpen was added to the view that calls stick(num, 20) to determine what xbox controllers are connected to the computer.
2. Variables were added to the Perspective view to store what xbox controllers are connected and their last update time.
3. A function called XboxInput was added with custom code to read the xbox inputs and use them to move the operator and viewpoint.
4. OnPreDraw was updated to call the XboxInput function.
5. The code to load/unload an item was moved to its own function so that the xbox A button and the spacebar handler can both call the function.

To handle Xbox input, I copied and modified stuff from the existing Perspective view code that is in the tree at VIEW:/standardviews/documentwindows/Perspective>eventfunctions/XboxInput

If you don't understand how referencing in the tree works, then this type of development may be more advanced than you can do by yourself right now. You may want to contact FlexSim for additional training or consulting work.
