[Input Action] Action binding doesn't refresh with ApplyBindingOverride() during runtime
Migrated bug from GitHub: https://github.com/Unity-Technologies/InputSystem/issues/247
I want a way to let users select a different button to trigger the fire action. Take the code example below, when I press num 1 then the original A key will be replaced with W key for that action.
public class TestBindingOverride: MonoBehaviour
{
public InputAction fireAction;
public void Awake()
{
fireAction = new InputAction(name: "fire", binding: "<Keyboard>/a");
fireAction.performed +=
ctx =>
{
Debug.Log("fire!");
};
}
public void OnEnable()
{
fireAction.Enable();
}
public void OnDisable()
{
fireAction.Disable();
}
public void Update()
{
if (Input.GetKeyDown(KeyCode.Alpha1))
{
fireAction.Disable();
fireAction.ApplyBindingOverride(path: "<Keyboard>/a", newBinding: "<Keyboard>/w");
fireAction.Enable();
}
}
}
The problem is that the binding override doesn't apply immediately, and I found it refreshed when any device is discovered and added to the system.
This is when I press num 1 to call ApplyBindingOverride(), but nothing happened. The A key still triggers the fire action but W key doesn't. (See Image_1)
When I turn on my Vive tracker (any other device will do), the system updates the binding from A key to W key. Now W key triggers the fire action but A key doesn't. (See Image_2)
Any idea on how to fix it? Or is there any better way to do this? Thanks.

Confirmed. InputActionRebindingExtensions isn't flushing resolved data.
Partial fix in 07b5979. Needs some related changes to happen to catch all the cases.
