Can't get platforming character to jump

Questions & Answers

Been scratching my head for days. Here’s my script

public class characterMovement : MonoBehaviour {

public float speed = 6.0f;
public float gravity = -75.0f;
public float jumpSpeed = 100.0f;
private Vector3 moveDirection = Vector3.zero;

void Start ()
{

}

void Update()
{
    CharacterController controller = GetComponent<CharacterController>();
    moveDirection = new Vector3(0, 0, Input.GetAxis("Horizontal"));
    moveDirection = transform.TransformDirection(moveDirection);
    moveDirection *= speed;
    
    //checking if grounded

    if (controller.isGrounded)
    {
        print("grounded!");
        if (Input.GetKeyDown(KeyCode.Joystick1Button0))
        {
            moveDirection.y = jumpSpeed;
            print("we jumpin");
        }

    }

    //move the thing

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

When I play the game and hit the “A” button on the 360 controller, I get my “we jumpin” message, which tells me its receiving the input, but I still can’t get the character to jump. My public floats are the same in the script as they are in the unity editor.

When adding jump height or applying gravity, always add or subtract, not make it directly equal.

moveDirection.y += jumpSpeed;

moveDirection.y += gravity; // Since your gravity is negative, I used +

Maybe use this:

   if(someKeyTouched)
        myRigidBody.AddForce(transform.up * jumpForce);

this script will make jump your rigidbody (2d or 3d) + if you add physics materia, you can make it bounce :slight_smile:
