Player able to jump when not grounded

Questions & Answers
1

Hey guys- I am having an issue with my game. I create a raycast to test if the player is grounded. If so, he should be able to jump… If not, he should. However I find that if I tap jump repeatedly, he jumps multiple times (even if not grounded) and sometimes jumps really high. Does anyone know how to fix this??

private bool isGrounded = false;

private void FixedUpdate()
    {
        //Move
        Movement();
    }

 private void Movement()
    {
            GroundCheck();
            //Apply jump if jump requested
            Jump();
    }

    private void GroundCheck()
    {
        //NOTE: MAKE SURE YOUR LAYERMASK EXCLUDES PLAYER IN THE INSPECTOR
        RaycastHit hit;
        if (Physics.Raycast(transform.position, Vector3.down, out hit, 1f, excludeCharacter))
        {
            isGrounded = true;
        }
        else
        {
            isGrounded = false;
        }
    }

    private void Jump()
    {
        if (jumpRequested && isGrounded)
        {
            rb.velocity += Vector3.up * jumpSpeed;
            jumpRequested = false;
        }
        else
        {
            jumpRequested = false;
        }
    }

can yoou put this line inside the if(physics.raycast…) in the groundCheck?

Debug.Log(hit.collider.name);

this will help you to know if there are any objects he is colliding with and that you should exclude since probably is a layer problem

Hi! You could try this: ` private bool isGrounded = false;
public LayerMask WhatIsGround;

private void FixedUpdate()
{
//Move
Movement();
}
private void Update() {
//NOTE: MAKE SURE TO SET THE LAYERMASK TO YOUR GROUND LAYER
isGrounded = Physics.Raycast(transform.position, Vector3.down, 1f, WhatIsGround);
if(Input.GetKeyDown(KeyCode.Space) && isGrounded) {
Jump();
}
}

private void Movement()
{

 }

 private void Jump()
 {
         rb.velocity += Vector3.up * jumpSpeed;
         jumpRequested = false;
 }`

I cleaned up your script a bit too.
PS. I assume that your game is 3D.
