Jumping Issues Character movement

Questions & Answers
1

I have created my first code, having a character interact around the environment. I coded my character to that when I press the space bar, he will jump. But it looks like when I hold the space bar for more than 1 second, he keeps going up and up or it seems like he is double jumping as you can see here: ProblemJump.mp4 - Google Drive

This is basically the code I have for my character:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
 
public class Player : MonoBehaviour
{
    Animator Anim;
    [SerializeField] float WalkSpeed = 0.001f;
    [SerializeField] float RotSpeed = .001f;
    [SerializeField] float RunSpeed = 0.001f;
    private AnimatorStateInfo PlayerLayer;
 
 
    // Start is called before the first frame update
    void Start()
    {
        Anim = GetComponent<Animator>();
    }
 
    // Update is called once per frame
    void Update()
    {
        PlayerLayer = Anim.GetCurrentAnimatorStateInfo(0);
        if (PlayerLayer.IsTag("MotionStop"))
        {
            //Character movement
            if (Input.GetAxis("Vertical") > 0)
            {
                transform.Translate(0, 0, WalkSpeed);
                Anim.SetBool("WalkForward", true);
            }
            if (Input.GetAxis("Vertical") < 0)
            {
                transform.Translate(0, 0, -WalkSpeed);
                Anim.SetBool("WalkBackward", true);
            }
            if (Input.GetAxis("Vertical") == 0)
            {
                Anim.SetBool("WalkForward", false);
                Anim.SetBool("WalkBackward", false);
            }
            if (Input.GetAxis("Horizontal") > 0)
            {
                transform.Rotate(0, RotSpeed * Time.deltaTime, 0);
                Anim.SetBool("WalkForward", true);
            }
            if (Input.GetAxis("Horizontal") < 0)
            {
                transform.Rotate(0, -RotSpeed * Time.deltaTime, 0);
                Anim.SetBool("WalkForward", true);
            }
            if (Input.GetButton("Fire1"))
            {
                Anim.SetBool("RunForward", true);
                transform.Translate(0, 0, RunSpeed);
            }
            else
            {
                Anim.SetBool("RunForward", false);
            }
        }
        if ((Input.GetButton("Jump")))
        {
            Anim.SetTrigger("Jump");
            GetComponent<Rigidbody>().velocity = new Vector3(0.4f, 8, 0.4f);
        }
        if (GetComponent<Rigidbody>().velocity.y == 0)
        {
            Anim.SetBool("Jump", false);
        }
    }
}

Did anyone of you guys experience this? Any help will be appreciated. :slight_smile:

It appears you’re using Input.GetButton which even if you press it once, because it’s in update it will detect it multiple times, try using Input.GetButtonDown instead, this will register it just once.

If that fixes it, if you can jump even while in the sky, i suggest looking up online how to check if a player is grounded, there will be lots of results, i Don’t have time to write out an example here, videos will explain it better anyway.

Hope it helps.
