Double Jump Problem

Unity Engine
1

Hi,
I’m writing a code for my platformer game .I have an issue with double jump .When I jump after 3 jump I’m not able to jump anymore also when I collide with object in scene.
My code is:

using UnityEngine;
using System.Collections;

public class PlayerController : MonoBehaviour {
    public float moveSpeed;
    public float jumpHeight;
    private Rigidbody2D rigi;
    public Transform groundCheck;
    public float groundCheckRadius;
    public LayerMask whatIsGround;
    private bool grounded;
    private bool doubleJumped;
    // Use this for initialization
    private void Awake()
    {
        rigi = GetComponent<Rigidbody2D>();
    }
    void Start () {
   
    }
    void FixedUpdate () {
        grounded = Physics2D.OverlapCircle(groundCheck.position, groundCheckRadius,whatIsGround);
                    }
    // Update is called once per frame
    void Update () {
        if (grounded)
                        doubleJumped = false;
            if(Input.GetKeyDown (KeyCode.Space) && grounded)
            {
            //rigi.velocity = new Vector2(rigi.velocity.x, jumpHeight);
            Jump ();
        }
        if(Input.GetKeyDown (KeyCode.Space) && !doubleJumped && !grounded)
        {
            //rigi.velocity = new Vector2(rigi.velocity.x, jumpHeight);
            Jump();

            doubleJumped=true;
        }
        if(Input.GetKey (KeyCode.RightArrow))
        {
            rigi.velocity = new Vector2(moveSpeed, rigi.velocity.y);
        }
        if(Input.GetKey (KeyCode.LeftArrow))
        {
            rigi.velocity = new Vector2(-moveSpeed, rigi.velocity.y);
        }
    }
    public void Jump(){
        rigi.velocity = new Vector2(rigi.velocity.x, jumpHeight);
    }
}

Thanks :slight_smile:

Is it ALWAYS after 3 jumps? Doesn’t seem to be any issue with your code. All I can think of is that maybe your groundCheck.position isn’t hitting your ground properly, so it’s not setting doubleJumped back to false.

Trying doing a Debug.Log(doubleJumped); on your Update function - this will output the value of doubleJumped to the console window, and see if doubleJumped is being properly set back to false every time.
