GUI.FocusControl working partially

Question

Hi,

I'm working now in a pause screen where you have the following options:

Continue Playing
Adjust Volume -> Triggers a new menu screen to adjust the volume
Exit -> Triggers a new menu screen to confirm the selection

There if i move with the keyboard or the joystick the GUIFocusControl is working fine, changing the colors of the buttons when is active or onHover.

The problem comes with the "Adjust Volume Menu", the keyboard is changing betweeen options, but it doesnt' change the colors of the button unless i use the mouse onHover:

Volume Menu - No active buttons or bar

Volume Menu - Mouse on Hover on the bar

Volume Menu - Mouse on Hover on the button

Also, this is working just fine in the confirm menu:

Confirm menu - Just keyboard

The worst part of all, is that i'm using almost the same script in another game and is working just fine. I really don't know what is happening.

I hope you can help me out here.

I leave the script right here:

in function VolumeMenu() you have GUI.SetNextControlName("Go Back");

but in the strings you have private var volumeMenu:String[] = ["Volumen", "Volver"];

it should be private var volumeMenu:String[] = ["Volumen", "Go Back""];

Oh my godness. This was it! I just couldn't see it :/

Thanks, it works great now.

At least this script could be an example to make multiple menus for somebody.

Thanks
