Why can I not jump with my tutorial First-Person Controller in Unity?-CodePudding

I followed Brackey's Unity 1st person controller tutorial and am unable to jump.

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

public class PlayerMovementScript : MonoBehaviour
{

    public CharacterController controller;

    public float speed = 12f;
    public float gravity = -9.81f;
    
   [Header("Keybinds")]
    public KeyCode jumpKey = KeyCode.Space;


    public float JumpHeight = 3f;

    public Transform groundCheck;
    public float groundDistance = 0.4f;
    public LayerMask groundMask;

    Vector3 velocity;
    bool isGrounded;

    // Update is called once per frame
    void Update()
    {

        isGrounded = Physics.Raycast(transform.position, Vector3.down, 1   0.3f, groundMask);

        if (isGrounded && velocity.y < 0)
        {
            velocity.y = -2f;
        }



        float x = Input.GetAxis("Horizontal");
        float z = Input.GetAxis("Vertical");

        Vector3 move = transform.right * x   transform.forward * z;

        controller.Move(move * speed * Time.deltaTime);



        if (Input.GetKeyDown(jumpKey) && isGrounded)
        {
            velocity.y = Mathf.Sqrt(JumpHeight * -2f * gravity);
        }


        velocity.y  = gravity * Time.deltaTime;

        controller.Move(velocity * Time.deltaTime);
    }
}

I discovered that if I remove isGrounded from the if statement for jumping, then I can jump, but infinitely. If isGrounded is in the code, then I can not jump at all.

I tried removing isGrounded from the if statement, which gave me the ability to jump, but I could jump forever without touching the ground.

I tried removing the line velocity.y = gravity * Time.deltaTime; which I wasn't able to jump there.

I tried removing isGrounded, all references to it, and things involving the ground, which lead to jumping once and then continuing to float up.

I've tried changing isGrounded = Physics.CheckSphere(groundCheck.position, groundDistance, groundMask);to Physics.Raycast(transform.position, Vector3.down, 1 0.3f, groundMask); and that resulted in no change.

I double checked that the ground layer has been applied to the ground and that the GroundCheck has been linked and mask selected.

I am completely stumped as to why this is not working. Any and all help would be greatly appreciated, thanks!

You need to assign the ground mask in the inspector!!! you need to assign everything my player is doing fine after applying the ground mask

CodePudding user response：

Check your ground if it has the ground tag/layer selected in the inspector
