Double Jump Not working
//This is the code idk why but it only jumps once but everything seems correct please help me I'm stuck for days
void Update() {
//move
Movement();
if (IsGrounded())
{
Jump();
canDoubleJump = true;
}
else if (canDoubleJump == true)
{
Jump();
canDoubleJump = false;
}
void Movement()
{
if (Input.GetKey(KeyCode.D))
rb.velocity = new Vector2(moveForce, rb.velocity.y);
else if (Input.GetKey(KeyCode.A))
rb.velocity = new Vector2(-moveForce, rb.velocity.y);
else
rb.velocity = new Vector2(0, rb.velocity.y);
}
void Jump()
{
if (Input.GetKeyDown(KeyCode.Space))
{
rb.velocity = new Vector2(rb.velocity.x, jumpForce);
}
}
}
bool IsGrounded()
{
Vector2 position = transform.position;
Vector2 direction = Vector2.down;
float distance = 1.0f;
RaycastHit2D hit = Physics2D.Raycast(position, direction, distance, ground);
if (hit.collider != null)
{
return true;
}
return false;
}
try to add a int which tells your exactly jumpscore like public int jumpsDone and a int wich tells you how much jumps you can do like public int jumpsLeft.
than do this in your grounded function
if (IsGrounded() || jumpsDone < jumpsLeft)
{
Jump()
}
if(jumpsDone >= jumpsLeft){
if(IsGrounded()){
jumpsDone = 0;}
in your Jump function write this
void Jump()
{
if (Input.GetKeyDown(KeyCode.Space))
{
jumpsDone++;
rb.velocity = new Vector2(rb.velocity.x, jumpForce);
}
}
if u have any issues tell me pls

so firstly thank u for helping me in the first place. so I did everything and I "jumpsLeft = 2" & JumpsDone = 0" when declared. still doesn't work

i figured out the issue. Your groundcheck function didnt detected the ground so i fixed it. Let me know if this works :D using System.Collections; using System.Collections.Generic; using UnityEngine;
public class Walking : MonoBehaviour
{
[SerializeField] float moveForce;
[SerializeField] float jumpForce = 10;
public float groundDistance = 0.4f;
public Rigidbody2D rb;
public LayerMask ground;
bool canDoubleJump;
public BoxCollider2D boxCollider2d;
public int jumpHolder;
public int jumpsDone = 0;
public int jumpsLeft = 2;
public Transform groundCheck;
void Start()
{
rb = GetComponent<Rigidbody2D>();
}
void Update()
{
void Movement()
{
if (Input.GetKey(KeyCode.D))
rb.velocity = new Vector2(moveForce, rb.velocity.y);
else if (Input.GetKey(KeyCode.A))
rb.velocity = new Vector2(-moveForce, rb.velocity.y);
else
rb.velocity = new Vector2(0, rb.velocity.y);
}
void Jump()
{
if (Input.GetKeyDown(KeyCode.Space))
{
rb.velocity = new Vector2(rb.velocity.x, jumpForce);
jumpsDone++;
}
}
//move
Movement();
//jump
if (IsGrounded() || jumpsDone < jumpsLeft)
{
Jump();
}
if (jumpsDone >= jumpsLeft && IsGrounded())
{
jumpsDone = 0;
}
}
public bool IsGrounded()
{
float extraHeightText = .01f;
RaycastHit2D raycastHit = Physics2D.Raycast(boxCollider2d.bounds.center, Vector2.down, boxCollider2d.bounds.extents.y + extraHeightText, ground);
if(raycastHit.collider != null)
{
return true;
}
else
{
return false;
}
}
void FixedUpdate()
{
}
}
doesn't work. i cant even jump, what do I need to assign to Ground Check. (I assigned the tile map still doesn't work)
you dont have to asign anything to GroundCheck i just forgot to delete this. Did you added the ground layer to your ground object? did you attached this script to your player? Add this to the if statement of the IsGrounded function
Debug.Log("is Grounded");
Tell me if this debug works
