Resolved Coroutine error

this is my first time posting here so bear with me. I'm trying to code a bounce pad of sorts, and it involves using a basic coroutine, but because of this error:

'Exerter.Exert(Collider)': not all code paths return a value

it's not working.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Exerter : MonoBehaviour
6. {
7.     [Tooltip("Box collider that checks if the player is going to be bounced")]
8.     public GameObject trigger;
9.     bool bounces;
10.     public bool singleUse;
11.  
12.  
13.     [Tooltip("X force applied to the player")]
14.     public float xForce;
15.     [Tooltip("Z force applied to the player")]
16.     public float zForce;
17.     [Tooltip("Upwards force applied to the player")]
18.     public float yForce;
19.  
20.  
21.     void OnTriggerEnter(Collider other)
22.     {
23.         if (other.CompareTag("Player"))
24.         {
25.             StartCoroutine(Exert(other));
26.         }
27.     }
28.  
29.     IEnumerator Exert(Collider player)
30.     {
31.         PlayerMovement movement = player.GetComponent<PlayerMovement>();
32.  
33.         if (bounces)
34.         {
35.             if (movement.velocity.y <= 0)
36.             {
37.                 movement.velocity.x = xForce;
38.                 movement.velocity.z = zForce;
39.                 movement.velocity.y = yForce;
40.  
41.                 if(singleUse)
42.                 {
43.                     bounces = false;
44.                 }
45.             }
46.         }
47.     }
48. }
49.  

 

You need to return something from this method. I usually use WaitForSeconds for that sort of thing.

Code (CSharp):

1. IEnumerator Exert(Collider player)
2.     {
3.         PlayerMovement movement = player.GetComponent<PlayerMovement>();
4.         if (bounces)
5.         {
6.             if (movement.velocity.y <= 0)
7.             {
8.                 movement.velocity.x = xForce;
9.                 movement.velocity.z = zForce;
10.                 movement.velocity.y = yForce;
11.                 if(singleUse)
12.                 {
13.                     bounces = false;
14.                 }
15.             }
16.         }
17.         yield return new WaitForSeconds(0.1f);
18.     }

To be honest, you could probably simplify this by replacing the Coroutine with Rigidbody.AddForce.

 

I am not using rigid bodies, I programmed my own physics for movement.
