Character Won't Jump

Hi. I’m a complete beginner to Unity3D, C# and programming, so I’m using this video as guidance. [Beginner] Moving and Jumping--Simple 3D Platformer | Tutorial Element 1 - YouTube . My only problem is that his character is jumping, while mine is not. Our scripts are identical so I don’t know what’s wrong. Can anyone help?

using UnityEngine;
using System.Collections;

public class SimpleCharacter : MonoBehaviour
{


    public CharacterController MyController;
    // Update is called once per frame
    public float Speed = 3f;
    public float GravityStrenght = 5f;
    public float JumpSpeed = 10f;
    public Transform CameraTransform;

    void Update ()
    {
        Vector3 myVector = new Vector3(0,0,0);

        //get input from the player
        myVector.x = Input.GetAxis("Horizontal");
        myVector.z = Input.GetAxis("Vertical");
        myVector = myVector * Speed*Time.deltaTime;

        myVector = CameraTransform.rotation * myVector; //rotate input by direction of camera

        //how do we get the jump button?
        float verticalVelocity = MyController.velocity.y - GravityStrenght*Time.deltaTime;
        if (Input.GetButtonDown("Jump")) 
        {
            //add jumpspeed to vertical velocity
            verticalVelocity +=JumpSpeed;
        }
        myVector.y = verticalVelocity*Time.deltaTime; //add new speed, to old speed, for acceleration
        //use input to move the character
        MyController.Move(myVector);
	}
}

I tried to see the script, but I’m not very good with unity because I’m quite new too, so try this :smiley: Unity - Scripting API: CharacterController.Move ( you need to attach to your player the character controller) anyway the script is this (it’s the same from the Unity scriptreference)

using UnityEngine;
using System.Collections;

public class SimpleCharacter : MonoBehaviour {
//Variables
public float speed = 6.0F;
public float jumpSpeed = 8.0F;
public float gravity = 20.0F;
private Vector2 moveDirection = Vector2.zero;

void Update() {
	CharacterController controller = GetComponent<CharacterController>();
	// is the controller on the ground?
	if (controller.isGrounded) {
		//Feed moveDirection with input.
		moveDirection = new Vector2(Input.GetAxis("Horizontal"), Input.GetAxis("Vertical"));
		moveDirection = transform.TransformDirection(moveDirection);
		//Multiply it by speed.
		moveDirection *= speed;
		//Jumping
		if (Input.GetButton("Jump"))
			moveDirection.y = jumpSpeed;

	}
	//Applying gravity to the controller
	moveDirection.y -= gravity * Time.deltaTime;
	//Making the character move
	controller.Move(moveDirection * Time.deltaTime);
}

}

So, the original script I had magically worked the next time i opened unity. Weird, but I’m glad! Thank you @IceEnry_lol for a suggestion :smiley:
