Movement Script in C# for Unity

Move.cs

private float speed = 2.0f;
public GameObject character;

void Update () {
		
		if (Input.GetKey(KeyCode.RightArrow)){
			transform.position += Vector3.right * speed * Time.deltaTime;
		}
		if (Input.GetKey(KeyCode.LeftArrow)){
			transform.position += Vector3.left* speed * Time.deltaTime;
		}
		if (Input.GetKey(KeyCode.UpArrow)){
			transform.position += Vector3.forward * speed * Time.deltaTime;
		}
		if (Input.GetKey(KeyCode.DownArrow)){
			transform.position += Vector3.back* speed * Time.deltaTime;
		}
	}

Add a cube into your game. Add a Rigidbody component to the cube. Add a Movement Script to the cube.
Paste the following.

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

public class Movement : MonoBehaviour
{
public float forwardsForce = 40f;
public float sidewaysForce = 40f;

public Rigidbody rb;

 void Update() 
{
    MovePlayer();
}

void MovePlayer() 
{
    if (Input.GetKey(KeyCode.UpArrow))
    {
        rb.AddForce(0, 0, forwardsForce * Time.deltaTime, ForceMode.VelocityChange);
    }
    if (Input.GetKey(KeyCode.DownArrow))
    {
        rb.AddForce(0, 0, -forwardsForce * Time.deltaTime, ForceMode.VelocityChange);
    }
    if (Input.GetKey(KeyCode.LeftArrow))
    {
        rb.AddForce(-sidewaysForce * Time.deltaTime, 0, 0, ForceMode.VelocityChange);
    }
    if (Input.GetKey(KeyCode.RightArrow))
    {
        rb.AddForce(sidewaysForce * Time.deltaTime, 0, 0, ForceMode.VelocityChange);
    }
}

}

Ctrl+ s to save go back into unity refrence the rigidbody.
And it should work.

### that didn't work for me so i modified it a bit:

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

public class Movement : MonoBehaviour
{
public float forwardsForce = 40f;
public float sidewaysForce = 40f;
public Vector3 up;
public Vector3 down;
public float jumpForce = 4f;

public Rigidbody rb;

void Start()
{
    up = new Vector3(0.0f, 2f, 0.0f);
    down = new Vector3(0.0f, -2f, 0.0f);
}
void Update()
{
    MovePlayer();
}

void MovePlayer()
{
    if (Input.GetKey(KeyCode.W))
    {
        rb.AddForce(up * jumpForce, ForceMode.Impulse);
    }
    if (Input.GetKey(KeyCode.S))
    {
        rb.AddForce(down * jumpForce, ForceMode.Impulse);
    }
    if (Input.GetKey(KeyCode.A))
    {
        rb.AddForce(-sidewaysForce * Time.deltaTime, 0, 0, ForceMode.VelocityChange);
    }
    if (Input.GetKey(KeyCode.D))
    {
        rb.AddForce(sidewaysForce * Time.deltaTime, 0, 0, ForceMode.VelocityChange);
    }
}

}

follow the same instructions.
Hope i helped someone!

None of these work for me :/

Alright, if anyone is still here, apply a rigidbody and collider to whatever object your player is, apply a script called "PlayerMovement", and copy this code:

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

public class PlayerMovement : MonoBehaviour
{

public float speed = 2f;
// Start is called before the first frame update
void Start()
{
    
}

// Update is called once per frame
void Update()
{
    if(Input.GetKey(KeyCode.W))
    {
        transform.position += Vector3.forward * speed * Time.deltaTime;
    }

     if(Input.GetKey(KeyCode.S))
    {
        transform.position += Vector3.back * speed * Time.deltaTime;
    }

     if(Input.GetKey(KeyCode.A))
    {
        transform.position += Vector3.left * speed * Time.deltaTime;
    }

     if(Input.GetKey(KeyCode.D))
    {
        transform.position += Vector3.right * speed * Time.deltaTime;
    }
}

}

It should work perfectly fine.

It's good but very slow

when I press play my character falls through the floor

Add Rigid body

what does DeltaTiem stands for?

the time that takes to load another frame

It's good but very slow

you can change the speed

it doesn't work,instead it does this

help.mp4

It's good but very slow

you can change the speed

HOWWW

Thanks it worked I just had to remove the Rigidbody so it doesn't fly all over the terrain

THANKS !!
It did, but it worked very slowly. I'll try another method. Thanks anyway! :)

making rigidbody a class in unity doesn't work for me. it gives me an error

the "vector3" in my visual studio it's not gteen, and it not works. please help!

hover on it and there will be a drop which is showing "using:UnityEngine" or something start with "using" tap on it but make sure you are using the lastest version of the unity.
