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.

Thanks Phil

We do have a PO for training for FLEXSIM. thinking of taking it on month of December

looks like it works. the GUI does not work for VR MODE

Is there a way we can also add VR mode to the perceptive view

Thanks

Attached is an updated version that adds a VR Mode button that turns on the Oculus Rift for the Perspective view in the custom Game View.

Changes in this version:

The button calls applicationcommand("switchviewvrmode", view, getchecked(c)), which toggles VR Mode on the specified view.

The XboxInput function handles re-centering the headset when you press the Back button:

if (wButtons & XINPUT_GAMEPAD_BACK)
    applicationcommand("recenteroculusrift");

The OnPreDraw sets a timer to repaint the view with the function IdleRepaint when in VR Mode or an Xbox controller is connected. (This makes the view continuously repaint when the model isn't running.)

Thanks Phil

This is super cool. the extent on what flexsim can do is mind boggling

Only thing is the when I move the right toggle thumb to turn and watch, the left toggle turns is right and right toggle turns it left. look like they are switched

Thanks again for everything so far

Regards

Raashid,

have you seen this:

https://answers.flexsim.com/questions/30260/how-i-can-use-and-configure-the-xbox-controller-in.html

This describes where the logic can be found to manipulate control through Xbox controller.

Yes I did

I don't really understand what below sentence means in the answer

"If you want to change what the controller sticks and buttons do, you can modify the FlexScript code in the node VIEW:/standardviews/documentwindows/Perspective>eventfunctions/XboxInput"

But this is more on how can I link the xbox controller to the custom GUI

Thanks for quick reponse
