unity 2d jump script code example

Example 1: unity how to make jump script

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class jump : MonoBehaviour
{
    public float jumpHeight = 7f;
    public bool isGrounded;
    public float NumberJumps = 0f;
    public float MaxJumps = 2;
    private Rigidbody rb;

    void Start()
    {
        rb = GetComponent<Rigidbody>();
    }

    void Update()
    {
        if (NumberJumps > MaxJumps - 1)
        {
            isGrounded = false;
        }

        if (isGrounded)
        {
            if (Input.GetButtonDown("Jump"))
            {
                rb.AddForce(Vector3.up * jumpHeight);
                NumberJumps += 1;
            }
        }
    }

    void OnCollisionEnter(Collision other)
    {
        isGrounded = true;
        NumberJumps = 0;
    }
    void OnCollisionExit(Collision other)
        {
            
    }
}

Example 2: unity 2d jump

rigidbody2D.AddForce(new Vector2(0, 10), ForceMode2D.Impulse);

Example 3: 2d jump unity code c#

using UnityEngine;
using System.Collections;

public class movingplayer : MonoBehaviour {

public Vector2 speed = new Vector2(10,10);

private Vector2 movement = new Vector2(1,1);

// Use this for initialization
void Start () {

}

// Update is called once per frame
void Update () {
    float inputX = Input.GetAxis ("Horizontal");
    float inputY = Input.GetAxis ("Vertical");

    movement = new Vector2(
        speed.x * inputX,
        speed.y * inputY);

    if (Input.GetKeyDown ("space")){
                         transform.Translate(Vector3.up * 260 * Time.deltaTime, Space.World);
                 } 

}
void FixedUpdate()
{
    // 5 - Move the game object
    rigidbody2D.velocity = movement;
    //rigidbody2D.AddForce(movement);

}
}
