Question by unity_VG19DPT6Sl_GcQ · Mar 05, 2021 at 06:25 PM · speedballresetreset-position

Can't reset speed

I want to reset the ball speed to its original state, because everytime it touches a trigger it gains 1.2 speed, but I'm not being able to reset the ball to its original speed.

My code is like this so far:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class Bola : MonoBehaviour
 {
     public float speed = 2.0f;
     public float maxSpeed = 10.0f;
     private Rigidbody2D rb;
     private Vector3 startPosition;
     public float difficultyMultiplier = 1.2f;
     private AudioSource audioSource;
 
     private float x;
     private float y;
     
     void Start()
     {
         rb = GetComponent<Rigidbody2D>();
 
         startPosition = transform.position;
         Launch();
 
         audioSource = GetComponent<AudioSource>();
 
     }
 
     void Update()
     {
 
         if (this.transform.position.x >= 9f)
         {
             this.transform.position = new Vector3(0f, 0f, 0f);
         }
 
         if (this.transform.position.x <= -9f)
         {
             this.transform.position = new Vector3(0f, 0f, 0f);
         }
     }
 
 
     private void Launch()
     {
         if (Random.Range(0, 2) == 0)
         {
             x = -1;
         }
         else
         {
             x = 1;
         }
 
         if (Random.Range(0, 2) == 0)
         {
             y = -1;
         }
         else
         {
             y = 1;
         }
 
         rb.velocity = new Vector2(speed * x, speed * y);
     }
 
     private void OnCollisionEnter2D(Collision2D collider)
     {
         audioSource.Play();
     }
 
     public void Reset()
     {
         transform.position = startPosition;
         Launch();
     }
 
     private void OnTriggerEnter2D(Collider2D collision)
     {
         if (collision.gameObject.tag == "Raquete")
         {
             if (difficultyMultiplier * speed < maxSpeed)
             {
                 speed *= difficultyMultiplier;
                 rb.velocity *= difficultyMultiplier;
             }
         }
     }
 }

If anyone could help me, I would be very grateful!

Where are you trying to reset the speed?? I only see where you are multiplying by the difficultyMultiplier. Anyhow, since you are changing the speed, you won’t have access to the original speed unless you cache that speed somewhere. So instead of just having speed and maxSpeed you should include a minSpeed for example and pass speed the minSpeed value in Start() and then anytime you want to reset it, just do it again speed = minSpeed
