❔ 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);
        }
    }
}

did you attach the script to the player?

cap5lut•13mo 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•13mo 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•13mo ago

TheRanger•13mo ago

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

ThundrOP•13mo ago

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

TheRanger•13mo ago

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

ThundrOP•13mo ago

yes ok so what should i do about that

TheRanger•13mo ago

can you show a screenshot to that

ThundrOP•13mo ago

TheRanger•13mo ago

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

ThundrOP•13mo ago

alr 1s where do i see the debug outcome

TheRanger•13mo ago

in where the error messages window

TheRanger•13mo ago

ThundrOP•13mo ago

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

TheRanger•13mo ago

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

ThundrOP•13mo ago

ok A and D work W doesnt neither does S

TheRanger•13mo ago

define doesnt work

ThundrOP•13mo ago

uh debug message not showing up

TheRanger•13mo ago

where did you place the debug.log ?

ThundrOP•13mo 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•13mo ago

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

ThundrOP•13mo ago

yep

TheRanger•13mo ago

weird

ThundrOP•13mo ago

same with W but not A and D

TheRanger•13mo ago

ThundrOP•13mo ago

thast what im saying

TheRanger•13mo ago

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

ThundrOP•13mo ago

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

TheRanger•13mo ago

did you save the file?

ThundrOP•13mo ago

yeah

TheRanger•13mo ago

usually u save with ctrl + s

ThundrOP•13mo ago

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

TheRanger•13mo ago

very weird

ThundrOP•13mo ago

yeah fr
