Basic Jump Pad help

So I don't use unityScript and I didn't use a player controller. Just a standard collision between two box colliders. I didn't see anything happening until I raised the value of "speed" 500 was good for me. Heres the code for jumpPad:

 public class jumpPad : MonoBehaviour {
 
     public int speed;
 
     void OnCollisionEnter(Collision other)
     {
         if (other.gameObject.CompareTag("Player"))
         {
             other.gameObject.GetComponent<Rigidbody>
                     ().AddForce(Vector3.up*speed);
         }
     }
 }

If your jumping script also use AddForce() the jump pad script and the jump script can be overlapped thus: you need to reset your characters RBs velocity before jump pads code runs. example is under below

     other.gameObject.GetComponent<Rigidbody>().velocity = Vector3.zero;
     other.gameObject.GetComponent<Rigidbody>().AddForce(Vector3.up*bounce, ForceMode2D.Impulse);

also; if u want to save your horizontal velocity you can use like this:

    other.gameObject.GetComponent<Rigidbody>().velocity = 
    new Vector3(other.gameObject.GetComponent<Rigidbody>().velocity.x,0,0);

Do not forget if your game is 2D you need to change Rigidbodys => Rigidbody2D and Vector3 => Vector2

good luck :)
