KeyBinding is not supported in Unity?

22 Jun 2017, 11:31

Hello,
I added some code below into the MainMenu.xaml under the sample Menu3D
<UserControl.InputBindings>
<KeyBinding Command="{Binding Start}" Key="A"></KeyBinding>
</UserControl.InputBindings>

It can work in WPF, but in Unity I got some errors:
NoesisException: Unable to convert 'A' to a valid value for property KeyBinding.Key (@10,8)
Noesis.Error.Check () (at Assets/NoesisGUI/Plugins/API/Core/NoesisError.cs:21)

Unity 5.6.0f3
NoesisGUI-2.0.2f2

Edit:
I found the code below is not supported after switching from WPF to Unity
_start.InputBindings.Add(new KeyBinding(((MenuModel)this.DataContext).Start, Key.Enter, ModifierKeys.None));
I don't know why Noesis.KeyBinding's property Key and Modifiers is readonly, and can't set them from constructor?

Hi,

It is failing because we incorrectly implemented KeyBinding.Key and KeyBinding.Modifiers as read-only properties.
Please file a ticket in our bugtracker and we will fix it as soon as possible.

Meanwhile the workaround is using the Gesture property instead:
Code: Select all
<UserControl.InputBindings>
    <KeyBinding Command="{Binding Start}" Gesture="A"></KeyBinding>
</UserControl.InputBindings>
Code: Select all
_start.InputBindings.Add(new KeyBinding
{
  Command = ((MenuModel)this.DataContext).Start,
  Gesture = new KeyGesture(Key.A, ModifierKeys.None)
});
