Question Can you do "button not pressed" using Input System in Send Messages

I'm making a simple FPS prototype. I want to be able to shoot when I hold down the Fire button.

As I'm using the Unity Starter FPS controller, I want to keep my Player Input in the "Send Messages" mode (not "Invoke Unity Events"). However in "Send Messages" mode, I don't have access to CallbackContext, so I can't find interactions like performed/hold etc.

Currently this is my code.

void OnFire()
{
//shoots gun
}

It works every time I tap the button, but not when I hold it. I could turn on a FireHeld bool, but I don't know how to turn it off as I can't find a way of saying "If Fire not pressed".

Any help??

 

Yeah, You can do something like this:
void OnFire(InputValue value)
{
if (value.isPressed)
{
// You press the button
}
else
{
// You unpressed the button
}
}
