[Solved]What am I doing wrong with my platform colliders ?

Hello there
, I recently started the long journey of learning C#, and after a few hours of watching and reading tutorials and digging into the Standard Assets controller scripts, I came up with my very first code prototype, which is supposed to be a 2.5D platformer character controller. It works decently well, the character can move left, right and jump. However, as far as my jump system is concerned, I included a bool called isGrounded that is required for the player to jump, and is set to true when a collider on the character encounters the ground. It works well, however, when I duplicate the cube that I use as a protoype floor to extend the initial platform, this second section does not trigger the collider ! I can't figure out why... Here's the code code

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class PlayerMovement : MonoBehaviour
6. {
7.  
8.     Rigidbody Rgbd;
9.     Animator animCtrl;
10.     CapsuleCollider p_Collider;
11.  
12.     public float speed;  //setting up floats
13.     public float altitude;
14.     public float jumpForce;
15.     public float moveForcef;
16.     public float hInput;
17.  
18.     public bool isGrounded;  //setting up bools
19.     private bool isRunning;
20.     private bool isJumping;
21.     private bool isCrouching;
22.  
23.     void Start () //Au démarrage...
24.     {
25.         Rgbd = GetComponent<Rigidbody> (); //.cache rigidbody and animator data
26.         animCtrl = GetComponent<Animator> ();
27.         isGrounded = false;  //by default, not grounded
28.     }
29.  
30.     void OnTriggerEnter ()  //on platform collide -> grounded
31.     {
32.         isGrounded = true; //grounded on
33.         Debug.Log ("Trigger enter");
34.     }
35.  
36.     void OnTriggerExit () //opposite
37.     {
38.         isGrounded = false;
39.         Debug.Log ("Trigger leave");  
40.     }
41.  
42.     void FixedUpdate ()  //each frame
43.     {
44.         float hInput = (Input.GetAxis("Horizontal"));
45.         Rgbd.AddForce (hInput * Vector2.right *moveForce); //when input, apply force
46.         if (isGrounded && Input.GetKeyDown(KeyCode.Space)) //if space pressed + grounded
47.         {
48.                 Rgbd.AddForce (jumpForce * transform.up);  //apply force up
49.                 Debug.Log ("Force applied");
50.         }
51.  
52.         else //and if not grounded
53.         {
54.             //nothing happens
55.         }
56.     }            
57. }

I apologize in advance for how clumsy this code probably is, since this is my first attempt ever... but if anyone has an idea why the collider doesn't happen to work out of the initial platform, I'd be relieved ! Thank you very much in advance

NB : I already set up the colliders and rigidbody

 

use OnTriggerStay insteadof OnTriggerEnter

 

Worked like a charm ! Thank you very much
