❔ im extremely new to c#/unity, i can't find the issue with this code

        if (Keyboard.IsKeyDown(Key.S))
        {
            transform.Translate(Vector.3.back * Time.deltaTime * Input.GetAxis("Horizontal") * moveSpeed);
        }

        if (Keyboard.IsKeyDown(Key.S))
        {
            transform.Translate(Vector.3.back * Time.deltaTime * Input.GetAxis("Horizontal") * moveSpeed);
        }

the transform.Translate line has the syntax error, ',' expected error, and i cant find the issue

yo like while im on the topic the whole script has no errors but it dont work

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerMovement : MonoBehaviour
{
    public float moveSpeed = 3f;
    // Start is called before the first frame update
    void Start()
    {

    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetKeyDown(KeyCode.A))
        {
            transform.Translate(Vector3.left * Time.deltaTime * Input.GetAxis("Horizontal") * moveSpeed);

        }

        if (Input.GetKeyDown(KeyCode.D))
        {
            transform.Translate(Vector3.right * Time.deltaTime * Input.GetAxis("Horizontal") * moveSpeed);
        }

        if (Input.GetKeyDown(KeyCode.W))
        {
            transform.Translate(Vector3.forward * Time.deltaTime * Input.GetAxis("Horizontal") * moveSpeed);
        }

        if (Input.GetKeyDown(KeyCode.S))
        {
            transform.Translate(Vector3.back * Time.deltaTime * Input.GetAxis("Horizontal") * moveSpeed);
        }
    }
}

TheRanger•8mo ago

did you attach the script to the player?

cap5lut•8mo ago

the script itself should indeed work if its attached to the game object (tho for W and S u want the vertical axis i would assume)

TheRanger•8mo ago

the code doesnt make sense for example Input.GetAxis("Horizontal") will always return 0 unless you hold down the key that is mapped to it

TheRanger•8mo ago

TheRanger•8mo ago

the question is, did you map the horizontal axis to D and A like in this image?

Thundr•8mo ago

ill check that one sec its attached, doesnt work how tf do i even get here 😭

TheRanger•8mo ago

https://docs.unity3d.com/Manual/comp-ManagerGroup.html

Thundr•8mo ago

yes ok so what should i do about that

TheRanger•8mo ago

can you show a screenshot to that

Thundr•8mo ago

TheRanger•8mo ago

ensure Update method is being called use Debug.Log or something

Thundr•8mo ago

alr 1s where do i see the debug outcome

TheRanger•8mo ago

in where the error messages window

TheRanger•8mo ago

Thundr•8mo ago

i didnt get any errors running it ok i see it yeah the updates are being called

TheRanger•8mo ago

now try to debug if the getkeydown is being called and debug the values that are placed in the Translate method

Thundr•8mo ago

ok A and D work W doesnt neither does S

TheRanger•8mo ago

define doesnt work

Thundr•8mo ago

uh debug message not showing up

TheRanger•8mo ago

where did you place the debug.log ?

Thundr•8mo ago

if (Input.GetKeyDown(KeyCode.S))
{
    Debug.Log("Hello: " + gameObject.name);
    transform.Translate(Vector3.back * Time.deltaTime * Input.GetAxis("Horizontal") * moveSpeed);
}

if (Input.GetKeyDown(KeyCode.S))
{
    Debug.Log("Hello: " + gameObject.name);
    transform.Translate(Vector3.back * Time.deltaTime * Input.GetAxis("Horizontal") * moveSpeed);
}

TheRanger•8mo ago

so when you press/hold S, it doesnt print ?

Thundr•8mo ago

yep

TheRanger•8mo ago

weird

Thundr•8mo ago

same with W but not A and D

TheRanger•8mo ago

Thundr•8mo ago

thast what im saying

TheRanger•8mo ago

btw for S and W it should be Input.GetAxis("Vertical") not Input.GetAxis("Horizontal")

Thundr•8mo ago

okay rly casue im tryna do a 3d WASD movement thing on the ground not flying

TheRanger•8mo ago

did you save the file?

Thundr•8mo ago

yeah

TheRanger•8mo ago

usually u save with ctrl + s

Thundr•8mo ago

i go to file and press save then go back to unity

TheRanger•8mo ago

very weird

Thundr•8mo ago

yeah fr
