[Inputs][UI] Joystick input not called

Unity Engine
1

Hi. I have an issue with the use of a joystick with the new Unity UI. I will take the horizontal axis as an example :

The left stick axis is binded under :

“L_XAxis_1” : Used for the gameplay itself. Only one entry in the input manager use this name.
“Menu_Horizontal” : Used for the menus. Severall entry use this name (for the keyboard and the D-Pad).

“L_XAxis_1” works fine, but “Menu_Horizontal” is keeping its default value of 0 when I move the axis.

Is there a reason for this ? Can’t we bind an axis under different names ? Or am I missing something ?

Thanks for your help.

ps : I am using Unity 5.2.1f1

Ok, so I have my answer. You can’t have the same input binded under several names. To overcome this problem, I made a small script that set the axis in the StandaloneInputModule by checking the input being used.

public string _HorizontalInputs;
public string _VerticalInputs;

private string[] _Hor;
private string[] _Ver;

void Update()
{
    for( int i = 0; i < _Hor.Length; i++ )
    {
        if( Input.GetAxisRaw( _Hor[i] ) != 0.0f )
        {
            StandaloneInputModule test = EventSystem.current.currentInputModule as StandaloneInputModule;
            test.horizontalAxis = _Hor[i];
            break;
        }
    }

    for( int i = 0; i < _Ver.Length; i++ )
    {
        if( Input.GetAxisRaw( _Ver[i] ) != 0.0f )
        {
            StandaloneInputModule test = EventSystem.current.currentInputModule as StandaloneInputModule;
            test.verticalAxis = _Ver[i];
            break;
        }
    }
}

void Start()
{
    _Hor = _HorizontalInputs.Split (new string[] {", "}, System.StringSplitOptions.RemoveEmptyEntries);
    _Ver = _VerticalInputs.Split (new string[] {", "}, System.StringSplitOptions.RemoveEmptyEntries);
}

You could have the array directly as public, but considering there is only three small strings, I choose to split one. Well, that’s just depend on how you prefer it…
