[new InputSystem] Impossible to get mouse movements

[GwenaelGuiraud]

Hi everyone,
I have a problem, I am trying to get the mouse movement using the Delta attribute but my method is not called.
Here is my action group:

My InputManager class:

public class InputManager : MonoBehaviour
{
    [HideInInspector] public float MouseX;
    [HideInInspector] public float MouseY;
    [HideInInspector] public Vector2 moveValue;

    public void OnMouseDelta(InputAction.CallbackContext context)
    {
        Debug.Log(context);
        Debug.Log("Mouse movement");
    }

    public void OnMove(InputValue value)
    {
        moveValue = value.Get<Vector2>();
    }

    private void OnPause() { PauseManager.PM.TogglePause(); }
}

All the other methods work well but when (in play mode) I move my mouse nothing appen.

If anyone have an idea I thank him in advance and for the moment I keep searching.

How are you hooking up your callback methods to the Input Actions? Are you using the PlayerInput component, or something else?

[Ian_1337]

There is an example from Unity’s Standard Assets with new Input system on the Github I think this is the link;
https://github.com/Unity-Technologies/Standard-Assets-Characters

public void OnMouseLook(InputAction.CallbackContext context)
        {
            var newInput = context.ReadValue<Vector2>();
            m_UsingMouseInput = true;
           
            //When using an InputGainAcceleration component, the look input processing should happen there.
            if (m_UseInputGainAcceleration)
            {
                if (m_CameraInputGainAcceleration.hasProcessedMouseLookInput)
                {
                    m_lookInput = Vector2.zero;
                    m_CameraInputGainAcceleration.hasProcessedMouseLookInput = false;
                }
            }
            else
            {
                // If the mouse look input was already processed, then clear the value before accumulating again
                if (m_HasProcessedMouseLookInput)
                {
                    m_lookInput = Vector2.zero;
                    m_HasProcessedMouseLookInput = false;
                }
            }
           
            m_lookInput += newInput;           
        }

Here is how it works in the action map

[GwenaelGuiraud]

I thank you but I prefere to do it myself without using cinemachine if it is possible.

[PraetorBlue]

W

@GwenaelGuiraud

I thank you but I prefere to do it myself without using cinemachine if it is possible.

Who said anything about Cinemachine?

[Ian_1337]

You don’t have to use Cinemachine, you just need to understand how the Control map has mouseLook as a value Vector2, and how to implement that into your code using the above example or Unity assets example.

[GwenaelGuiraud]

The link make a lot of reference about it.
And I have the same thing, my action map with MouseLook in Value : Vector2 bind to Mouse Delta but my method OnMouseLook still not called

[Ian_1337]

I had an issue with capitalization on words, try change MouseDelta to mouseDelta in your control map. (set it to value, vector2)

Can you show the updated script, I guess you simplified it somehow, something like this (i havent tested this)

        // Look input vector
        Vector2 m_lookInput;

public void OnMouseDelta(InputAction.CallbackContext context)
        {
            var newInput = context.ReadValue<Vector2>();
            m_lookInput += newInput;         
        }

[Ian_1337]

Also note (If using the Standard Asset for instance) you would also need to reference;

StandardControls.IMovementActions (whatever yours is named)

using UnityEngine.InputSystem;

public abstract class CharacterInput : MonoBehaviour, StandardControls.IMovementActions

[GwenaelGuiraud]

I don’t know if I must laugh or cry I have an error for all input : “MissingMethodException: InputManager.OnMove Due to: Attempted to access a missing member.” I already have it by the past for the OnJump because I didn’t used the IMovementActions interface and the use of InputValue instead of InputAction.CallbackContext resolve the error…

[Ian_1337]

If you show your new script I’ll try and help. Are you saying you now made Jump work (but it didn’t before?) and mouselook/mousedelta isn’t working?

[GwenaelGuiraud]

No all worked fine before exept mouselook/mousedelta but know nothing work

using UnityEngine;
using UnityEngine.InputSystem;

// StandardControls.IGameplayActions autmatically generated by unity based on the action map
// I have a PlayerInput element on my player linked to the action map
public class InputManager : MonoBehaviour, StandardControls.IGameplayActions
{
    [HideInInspector] public float MouseX;
    [HideInInspector] public float MouseY;
    [HideInInspector] public Vector2 moveValue;
    [HideInInspector] public Vector2 lookInput;
    [HideInInspector] public bool jump = false;

    public void OnMouseLook(InputAction.CallbackContext context)
    {
        Debug.Log("Mouse move");
        lookInput += context.ReadValue<Vector2>();
    }

    public void OnJump(InputAction.CallbackContext context)
    {
        if(context.started) { jump = true; }
        else if(context.canceled) { jump = false; }
    }

    public void OnMove(InputAction.CallbackContext context)
    {
        moveValue = context.ReadValue<Vector2>();
    }

    public void OnPause(InputAction.CallbackContext context)
    {
        PauseManager.PM.TogglePause();
    }
}

[Ian_1337]

Ok and the control map is now updated to mouseLook ^ value and vector 2 yeah?

[GwenaelGuiraud]

Yes since the first time you said it

[GwenaelGuiraud]

The player inspector

The action map

[Ian_1337]

Ok so when you update your control map, it will make a CS file; just make sure it’s updated;

further down this automatically generated script will be this;

Just make sure IMovementActions here is the correct reference you will use (whatever yours is named ‘IGameplayActions’)

Back to your script
try

using UnityEngine;
using UnityEngine.InputSystem;
// StandardControls.IGameplayActions autmatically generated by unity based on the action map
// I have a PlayerInput element on my player linked to the action map
public class InputManager : MonoBehaviour, StandardControls.IGameplayActions
{
    [HideInInspector] public float MouseX;
    [HideInInspector] public float MouseY;
    [HideInInspector] public Vector2 moveValue;
    [HideInInspector] public Vector2 lookInput;
    [HideInInspector] public bool jump = false;
    public void OnMouseLook(InputAction.CallbackContext context)
    {
     var newInput = context.ReadValue<Vector2>();
            lookInput += newInput; 
       Debug.Log("Mouse move");
    }
    public void OnJump(InputAction.CallbackContext context)
    {
        if(context.started) { jump = true; }
        else if(context.canceled) { jump = false; }
    }
    public void OnMove(InputAction.CallbackContext context)
    {
        moveValue = context.ReadValue<Vector2>();
    }
    public void OnPause(InputAction.CallbackContext context)
    {
        PauseManager.PM.TogglePause();
    }
}

[Ian_1337]

I just looked at mine (but i used the standard asset and changed it) and I don’t have a Player Input on my player lol, but it works without it

Here is how my map looks (title is StandardControls)

[GwenaelGuiraud]

So I try again later I have an appointement but a big thank you for your help.

[GwenaelGuiraud]

I removed the PlayerInput component and yes I have no more errors but no more action neither. Nothing, no jump, no move, no pause, etc…
