Jumping issues

Questions & Answers

I’ve been trying scripts of jumping and this works good for me:

using UnityEngine;
using System.Collections;

 [RequireComponent(typeof(Rigidbody))]
 public class PlayerController : MonoBehaviour {
 
     public Vector3 jump;
     public float jumpForce = 2.0f;
 
     public bool isGrounded;
     Rigidbody rb;
     void Start(){
         rb = GetComponent<Rigidbody>();
         jump = new Vector3(0.0f, 2.0f, 0.0f);
     }
 
     void OnCollisionStay()
     {
         isGrounded = true;
     }
 
     void Update(){
         if(Input.GetKeyDown(KeyCode.Space) && isGrounded){
 
             rb.AddForce(jump * jumpForce, ForceMode.Impulse);
             isGrounded = false;
         }
     }
 }

However, there are some issues that should be fixed:
-When the player is running and I press space, the jump is longer than it should be.
-When the player is jumping, if you press jump again, it makes another small jump. This only happens once per jump, so you can’t “fly”. How can I fix that??
Thank you.

Try to move your physics methods, like AddForce() to the FixedUpdate instead of Update. The longer jump might be caused by the fact that you are already moving/running, try to play with the Damping variable, and the Mass on your Rigidbody component of your Player.
