3D Sidescroller Character Controller

Unity Engine
1

I am trying to make Sidescroller movement script based on Character Controller. I have a big problem and I don’t know how to solve it. Slow falling, not touching the ground etc. If you know what I am trying to make, you sure know what my problem is. First, I had unexpected Z-axis moving which hasn’t been mentioned anywhere in my code. I used online documentation as help, so, as you can assume, I am not fully expirienced Unity user.

Code:

using UnityEngine;
using System.Collections;

public class ccMove : MonoBehaviour {

	CharacterController cc;

	public float speed = 6f;
	public float gForce = 20f;
	public float jumpSpeed = 10;

	private float xSpeed;
	private float ySpeed;
	private float movementSpeed;
	private Vector3 moveDirection;
	private Vector3 rotacija;
	
	// Use this for initialization
	void Start () {
		cc = GetComponent<CharacterController>();
	}
	
	// Update is called once per frame
	void FixedUpdate () {
	
		float side = Input.GetAxis("Horizontal");

		//if (side = 1) {Vector3 rotacija = new Vector3(0,0,0);} else {
		//if (side = -1) {Vector3 rotacija = new Vector3(0,180,0);} }
		transform.eulerAngles = rotacija;

		moveDirection = new Vector3(side, 0, 0);
		moveDirection = transform.TransformDirection(moveDirection);
		moveDirection *= speed;

		if (cc.isGrounded  Input.GetButtonDown("Jump")) {
			moveDirection.y = jumpSpeed;
		}

		moveDirection.y -= gForce *Time.deltaTime * 2f;

		cc.Move(moveDirection * Time.deltaTime);

		transform.position = new Vector3(transform.position.x, transform.position.y, 0);
	}
}

I was looking back at an old tutorials FPS movement script, but I guess I still don’t know how exactly this script is supposed to work, I mean cc.Move…does it check xyz Vector3 or direction *speed?
Else…I don’t know how to make character face the direction I want and move in it. Collisions aren’t responding too…
If someone has an idea how to make it, please remake this kode or post your own.

I hope this thread will be useful to someone. :smile:

Well I don’t know much too but, one thing that caught my eye is when I saw the “Vector3” part. Instead of Vector3, it should be Vector2, which shows 2D movement/direction.

I still get errors on line 38 but, beside that everything is right in the script and also has the no z-axis like you wanted.

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

public class ccMove : MonoBehaviour
{

    CharacterController cc;

    public float speed = 6f;
    public float gForce = 20f;
    public float jumpSpeed = 10;

    private float xSpeed;
    private float ySpeed;
    private float movementSpeed;
    private Vector2 moveDirection;
    private Vector2 rotacija;

    void Start()
    {
        cc = GetComponent<CharacterController>();
    }

    void FixedUpdate()
    {

        float side = Input.GetAxis("Horizontal");

        //if (side = 1) {Vector3 rotacija = new Vector3(0,0,0);} else {
        //if (side = -1) {Vector3 rotacija = new Vector3(0,180,0);} }
        transform.eulerAngles = rotacija;

        moveDirection = new Vector2(side, 0);
        moveDirection = transform.TransformDirection(moveDirection);
        moveDirection *= speed;

        if (cc.isGrounded Input.GetButtonDown("Jump"))
            {
            moveDirection.y = jumpSpeed;
            }
        moveDirection.y -= gForce * Time.deltaTime * 2f;

        cc.Move(moveDirection * Time.deltaTime);

        transform.position = new Vector2(transform.position.x, transform.position.y);
    }
}

You forgot to add the && in the middle of the if statement, you should try it now.
