Keep Jump Height

Unity Engine
1

In my Script i’m using a jump Force, the reason being is because i don’t know any other way of jumping.

So sometimes when the Object Jumps it lowers its jump height when i move, any way of going around this?

this is my code

using UnityEngine;
using System.Collections;
public class SimpleController : MonoBehaviour {

[HideInInspector] public bool jump = false;


public float Speed = 0f;
public Transform groundCheck;
public float JumpForce;


private float move = 0f;
private bool grounded = false;
private Rigidbody2D rb2d;
    void Awake () {
        rb2d = GetComponent<Rigidbody2D>();
    }
    void Update ()
    {
        grounded = Physics2D.Linecast(transform.position, groundCheck.position, 1 << LayerMask.NameToLayer("Ground"));


        transform.eulerAngles=new Vector3(0,transform.eulerAngles.x,transform.eulerAngles.y); // Lock Rotations

        if(grounded)
        {
            jump = true;
        }
    }
    void FixedUpdate () {
        move = Input.GetAxis ("Horizontal");
        GetComponent<Rigidbody2D>().velocity = new Vector2 (move * Speed, GetComponent<Rigidbody2D>().velocity.y);
        if (jump)
        {
            rb2d.AddForce (new Vector2 (rb2d.velocity.x,JumpForce));
            jump = false;
        }
    }
}

It’s problem with addforce, the longer your Physic2D linecast check the layermask, the bigger jump force, when u move your player, time check will be shorter and the force is lower. u can jump by add the velocity directly to your player like :
this.rigidbody.velocity=new Vector2();

I would avoid using Physics for platforming. It’s somewhat hard to get it to do what you want it to. But there is a great tutorial for a simple and effective platforming system here: https://www.youtube.com/playlist?list=PLFt_AvWsXl0f0hqURlhyIoAabKPgRsqjz

With this tutorials, system you set the jump height and jump duration which is a bit more intuitive for designing a game.
