cube jump - script not working and with no errors

[Bayan_x94]

hello
I’m making an endless runner kinda thing there’s the problem:
the cube jumps just one time and then it doesn’t jump at all when it fall in the next tile / ground
Any help ??

using UnityEngine;
using System.Collections;

public class PlayerController : MonoBehaviour {
    
    public float speed = 15.0F;
	private Rigidbody rb;
    public Vector3 jump;
    public float jumpForce = 2.0f;
    public bool isGrounded;

    //Use this for initialization
    void Start () {
		rb = GetComponent<Rigidbody>();
        jump = new Vector3(0.0f, 2.0f, 0.0f);
    }
	
	// Update is called once per frame
	void Update () {
		transform.Translate (Vector3.forward * (speed) * Time.deltaTime);

        if (Input.GetKeyDown(KeyCode.Space) && isGrounded)
        {

            rb.AddForce(jump * jumpForce, ForceMode.Impulse);
            isGrounded = false;
        }
    }
}

Your not setting IsGrounded to true when you land. You could do this with this code:

void OnCollisionEnter(Collision col)
{
    if (col.gameObject.name == "insert platform object name here")
    {
        isGrounded = true
    }
}

Hope this helps!
