Cannot Jump or fall while while moving?

Questions & Answers
1

Hello, all. I have been working on making my player character jump, and he jumps fine as long as he is not moving. If he is moving, however, ie I am pressing the keys to move him, he slowly ascends, seemingly ignoring gravity or the amount of force the Rigidbody added until I stop pressing the keys and he descends as desired. After I make him jump while idling, I can make him stay in the air by walking around, which is also undesirable. I don’t recall ever experiencing this before.

Here’s a section of the code so far.

public class PlayerScript : MonoBehaviour
{

    public Animator Anim;
    public Rigidbody RBody;

    public float speed = 3f;
    public float horizontalSpeed = 2.0f;
    public float verticalSpeed = 2.0f;
    public float jumpForce = 2.0f;



    public Vector3 jump;
    void Update()
    {
        float h = horizontalSpeed * Input.GetAxis("Mouse X");
        transform.Rotate(0, h, 0);
        transform.Translate(0, 0, speed * Input.GetAxis("Vertical") * Time.deltaTime);
        Anim.SetFloat("speed", Input.GetAxis("Vertical"));

        if (Input.GetKeyDown(KeyCode.Space))
        {
            Jump();
        }
    
    void Jump()
    {
        jump = new Vector3(0.0f, 2.0f, 0.0f);
        RBody.AddForce(jump * jumpForce, ForceMode.Impulse);
    }

Hey,

Get rid of the Vector3 jump.

Replace your Jump() function with this

void Jump()
         {
             RBody.AddForce(0.0f, jumpForce, 0.0f, ForceMode.Force);
         }
3

transform.Translate(0, 0, speed * Input.GetAxis(“Vertical”) * Time.deltaTime);

With this line, you’re telling it to stay in the same posisiton with the exception of your vertical input. If you want physics to be applied, stop overriding it by using transform to move your gameObject.

Whoa…easier than I thought. Just add the jump function before the move function, apparently. It works like a charm.

void Update()
{
    if (Input.GetButtonDown("Jump") && isGrounded == true)
    {
        Jump();
    }
    //MovePlayer();
}
