How to fake a keyboard Up / Down press event for the Navigation in new Unity GUI system to work?

I've created some buttons with the new GUI system and have set the next up and down buttons to be selectable with the "Select On Up" and "Select On Down" provided by the module in the inspector.

They only work with the up and down arrows from the keyboard and also accept to click on the selected button by pressing space or enter.

I'm building this menu for an Ouya game so I need the up and down events to be sent from the controller instead of a keyboard (also the enter key should be sent from another key in the controller).

My plan is to make a script that takes the button from the Ouya controller and fakes a keyboard up / down arrow event so it makes the GUI work with the new Unity GUI system.

something like:

if (OuyaSDK.OuyaInput.GetButton(playerNum, OuyaController.BUTTON_DPAD_DOWN))
{
//Some code to fake a down arrow key pressed event so the GUI reacts to it
}

Can somebody tell me how to send the key press event so the GUI finally works with a controller instead of a keyboard?

 

Right, you don't need to "fake" the input from the controller, you just need to build your own "Ouya" InpuModule.
If you look at the source and have a look at the StandaloneInputModule, you will see how the Up/Down keys are used.
Then create your own input module using your input settings and then attach it to the EventSystem in your scene.

 

How can I see the source of the Standalone Input Module ? (edit script doesn't open the source file from these default generated scripts)

 

From the Unity UI Open source project on Bit bucket of course.
