can someone help me with this script??

this is a 2d platform game that should go forward automaticly
if i press mouse button it (the player) should jump

idk what is wrong

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using System.Security.Cryptography;
4. using UnityEngine;
5.  
6. public class NewBehaviourScript : MonoBehaviour
7. {
8.     public Rigidbody2D rb;
9.     public Transform groundCheck;
10.     public float groundCheckRadius;
11.     public LayerMask whatIsGround;
12.     private bool onGround;
13.  
14.  
15.     // Start is called before the first frame update
16.     void Start()
17.     {
18.         rb = GetComponent<Rigidbody2D>();
19.  
20.      
21.     }
22.  
23.  
24.     // Update is called once per frame
25.     void Update()
26.     {
27.         rb.velocity = new Vector2(1, rb.velocity.y);
28.         onGround = Physics2D.OverlapCircle(groundCheck.position, groundCheckRadius, whatIsGround);
29.  
30.  
31.         if (Input.GetMouseButtonDown(0) && onGround)
32.         {
33.             rb.velocity = new Vector2(rb.velocity.x, 3);
34.  
35.         }
36.     }
37. }
38.  

 

You'll need to describe what you're actually seeing occurring. Is the character not jumping?

 

yes it doesn't jump! it likes falls out of the map after it reatches the end of the terrain

 

Throw in a Debug.Log in the GetMouseButtonDown part so you can see if it is actually calling or not. If it is calling, then you may need to increase the value of the jump. Create a public float or int called jumpForce or something and replace that 3 with it so you can change it in the inspector while you are testing (during play). My guess is that the mass of the player is too high and the force applied isnt enough.
