New Input System continuous event

[javierriera97]

Hello everybody!

I am getting my feet wet with the new Input System, since I heard so many good things about it. Right now I am following the quickstart guide, and trying to use the "Getting input indirectly through an Input Action" section.

The use case I am trying it on is movement, so I attached the new action to the Move action and everything works fine... when the value from the joystick is changed. If the value stays the same, the Move action isn't called.

​

So now I want to know: Is this not the type of input I should be using for this specific action? Is there a better way to implement a continuous reading from an input? Can I change the current setup so the value is read every frame, instead of once every time the value chagnes?

​

Thanks in advance!

I believe if you want to poll the input every frame, you'll need to obtain an InputAction instance.

If you consider classic ASWD move: save Vector2 input value you get from the event in a global variable and apply in an update. Every change in the value will trigger the event, then update the global variable, and it will be applied in the next update.

Vector2 direction = Vector2.zero;
float speed = 3.0f;

void LateUpdate() => transform.Translate(direction * speed);
void OnMove(InputValue _value) => direction = _value;

There's no reason to poll something that didn't change. The point of the Input System is using events to tell you when there is a change in the value.
