What am I missing? Cant jump

Unity Engine

What am I missing here? Unity isn’t giving me any scripting errors. But I cant get off the ground

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

public class ActorMovement : MonoBehaviour {

    public float speed = 10;
    public float jumpForce = 10f;

    public bool isGrounded;

    public Vector3 jump;
    CharacterController controller;
    Rigidbody rb;

    void Start () {
        controller = GetComponent<CharacterController>();
        rb = GetComponent<Rigidbody>();
        jump = new Vector3(0.0f, 3.0f, 0.0f);
    }

    void OnCollisionStay()
    {
        isGrounded = true;
    }

    void Update () {
        float hAxis = Input.GetAxis("Horizontal");
        float vAxis = Input.GetAxis("Vertical");

        if (Input.GetKeyDown(KeyCode.Space) && isGrounded)
        {

            rb.AddForce(jump * jumpForce, ForceMode.Impulse);
            isGrounded = false;
        }

        controller.SimpleMove(transform.forward * vAxis * speed * Time.deltaTime);
        transform.Rotate(transform.up, hAxis + Time.deltaTime);

    }

}

Lets do some debugging!

Why dont you add a debug log to see what is going on. For example:

Debug.Log("Space: " + Input.GetKeyDown(KeyCode.Space) + ", isGrounded: " + isGrounded);

Compare that to what you think the values should be.

isGrounded is a public variable. What is it’s value when you’re playing?

You guys are quick,

With the public var enabled it goes from:
Space: False, isGrounded: True
to:
Space: False, isGrounded: False

With it Disabled:
Space: False, isGrounded: False
to:
Space: False, isGrounded: False

No, hes got a texture

Weird that “space” is “false” in all cases.

Try using
Input.GetKey(KeyCode.Space); instead of GetKeyDown.

7

False still

How about doing the isGrounded check as displayed here:

Solved in the end by my teacher directing me to unity documentation examples

[RequireComponent(typeof(CharacterController))]
public class ActorMovement : MonoBehaviour
{

    public float speed = 6.0F;
    public float jumpSpeed = 8.0F;
    public float gravity = 20.0F;

    private Vector3 moveDirection = Vector3.zero;
    private CharacterController controller;

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

    void Update()
    {

        if (controller.isGrounded)
        {
          //  Debug.Log("Jump: " + Input.GetButton("Jump") + " ,isGrounded: " + controller.isGrounded);

            float rotation = Input.GetAxis("Horizontal");
            transform.Rotate(transform.up, rotation);

            moveDirection = new Vector3(0, 0, Input.GetAxis("Vertical"));
            moveDirection = transform.TransformDirection(moveDirection);
            moveDirection *= speed;

            if (Input.GetButton("Jump"))
                moveDirection.y = jumpSpeed;
        }

        moveDirection.y -= gravity * Time.deltaTime;
        controller.Move(moveDirection * Time.deltaTime);
    }
}
