❔ GetAxis wont work

public class Driver : MonoBehaviour { // Start is called before the first frame update const float MoveUnitsPerSecond = 5; float horizontalInput = Input.GetAxis("Horizontal"); float verticalInput = Input.GetAxis("Vertical");
// Update is called once per frame void Update() { //move game object as needed Vector3 position = transform.position; if (horizontalInput != 0) {
position.x += horizontalInput * MoveUnitsPerSecond * Time.deltaTime;
} if (verticalInput != 0) {
position.x += verticalInput * MoveUnitsPerSecond * Time.deltaTime; } transform.position = position;
} } Why wont GetAxis work, the course i am going off of has this exact code but unity is saying that I cannot call GetAxis("Horizontal") from a monobehavior constructor

float horizontalInput = Input.GetAxis("Horizontal");
This tries to set horizontalInput to the axis when the object is first being initialized. It doesn't really make sense to do this when it's being created, as you probably want to check for input on every frame or something.

horizontalInput = Input.GetAxis("Horizontal"); in Update.

You'd move the calls to Update() Though I think in unity 2023 there is a new input system and the whole GetAxis is avoided, but don't quote me on that 😅

It works now, thank you

All of my focus on C# will be in Unity, i am taking a course on coursera for it Well now another problem has uprisen My sprite in unity will not move vertically

Kouhai ／人◕ ‿‿ ◕人＼•394d ago
As Thinker' has explained, you need to move the code for vertical input to update as well
O
Odin•394d ago
I have

Where? Ah
O
Odin•394d ago
void Update() { float verticalInput = Input.GetAxis("Vertical"); float horizontalInput = Input.GetAxis("Horizontal"); //move game object as needed Vector3 position = transform.position; if (horizontalInput != 0) {
position.x += horizontalInput * MoveUnitsPerSecond * Time.deltaTime;
} if (verticalInput != 0) {
position.x += verticalInput * MoveUnitsPerSecond * Time.deltaTime; } transform.position = position;
}

You have a bug in your code you're setting position.x instead of y
O
Odin•394d ago
oh i saw itt as you were typing thanks all
T
Thinker•394d ago
Also you don't actually need the ifs here
K
Kouhai ／人◕ ‿‿ ◕人＼•394d ago
Yeah
T
Thinker•394d ago
If either of them is 0 then the entire expression will be 0 so += won't do anything
O
Odin•394d ago
is that why, after changing the postion.x to y it still wont move vertically nvm i caught my error
