New input system triggers started when pressing AND releasing the trigger

Hi! I’ve been trying to implement the new input system, but the started phase is triggered not only when I press the trigger but also when I release it.

It works fine with the mouse left click and with another generic controller I have which has a button trigger (it just returns a value of 0 or 1). However, with the PS4 controller that has a gradual trigger, the input system triggers started when releasing too unless I release it really fast. I’d say it isn’t controller’s fault, because it works fine in other games, its values when releasing are ok (I’ve checked it in a web), and I’ve tried two different PS4 controllers.

This is my code:

public void Fire(InputAction.CallbackContext context)
{
    if (context.started)
    {
        weapon.GetComponent<WeaponControl>().StartFiring();
    }
    else if(context.canceled)
    {
        weapon.GetComponent<WeaponControl>().StopFiring();
    }

    print("Fire triggered. Phase : " + context.phase);
}

When I press and release the mouse, these are the messages I get on the console:

FireTriggered. Phase : Started
FireTriggered. Phase : Performed
FireTriggered. Phase : Canceled

And these are the messages I get when pressing the PS4 controller trigger:

FireTriggered. Phase : Started
FireTriggered. Phase : Performed
FireTriggered. Phase : Canceled
FireTriggered. Phase : Started
FireTriggered. Phase : Canceled

These are my project settings (although I’ve changed them multiple times and none of the configurations worked):

Default Button Press Point: 0.75
Button Release Threshold : 0.5

I have no interactions or processors in my input map.

I ran into a similar problem (2 years later!) Instead of doing work in Started I had to do the work in Performed and that fixed it. In the newer input system that’s changing from:

InputAction.Started += OnRightTriggerPressed

to:

InputAction.Performed += OnRightTriggerPressed

I would try to set up an Interaction for the controller, as Trigger Behaviour choose Press Only that worked fine for me.
