If I setup an axis with two button (positive and negative) and press both, I have an unexpected behaviour :
GetAxis() return the value of the first button pressed, the second button seems to be ignored.
I thought that pressed the two buttons at the same time will produce zero.
Is there a way to setup the axis to work this way ? Or I have to manage this in my script ?
Thanks in advance.
As requested, a screenshot and a piece of code :
float xAxis = Input.GetAxis("Horizontal");
Not sure if you’ve found a solution yet but if anyone else is stuck try using Input.GetAxisRaw(). Keep in mind that GetAxisRaw() does not smooth input values, so it will return a value of either 1, -1 or 0, whereas GetAxis() will return values in-between 1 and -1 (or 0 if no input is detected).
This solution worked perfectly for my very basic FPS movement script:
public class FPS_Move : MonoBehaviour
public float _force, _maxSpeed;
private float _currentSpeed, z, x;
private Vector3 _direction;
private Rigidbody _rBody;
_direction = Vector3.zero;
_rBody = GetComponent<Rigidbody>();
_currentSpeed = _rBody.velocity.magnitude;
if (_currentSpeed < 0)
_currentSpeed = 0;
x = Input.GetAxisRaw("Horizontal");
z = Input.GetAxisRaw("Vertical");
if (x != 0 || z != 0)
_direction = transform.right * x + transform.forward * z;
_rBody.AddForce(_direction * _force, ForceMode.Acceleration);
if (_rBody.velocity.magnitude > _maxSpeed)
_rBody.velocity = _rBody.velocity.normalized * _maxSpeed;
