Input.ResetInputAxes

Description

Resets all input. After ResetInputAxes all axes return to 0 and all buttons return to 0 for one frame.

This can be useful when respawning the player and you don't want any input from keys that might still be held down.

          Input.ResetInputAxes();

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    void Example() {
        Input.ResetInputAxes();
    }
}
