checkPoint & playerpref

hello, can someone help me with a problem I've been blocking for a few days and found nothing on the net.

So there you go, I'm training to design a Unity 2D game, Mario type. and I want to make a checkpoint system. Thus, the player could revive at the last chechpoint after seeing an advertisement (Rewarded AD). So the pub part, it works, after viewing, there is "reloading the part" and replacing the character at the first checkpoint.

the problem is: it always comes back to the first checkpoint, it does not save the coordinates of the next checkpoints, I have tried everything: I put the checkpoints in prefabs, I took them out, I tried to do them separately, I tried a courotine, to erase the data and reload them after a new collision and nothing helps, it always comes back to the first checkpoint. this is my, my script

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class CheckPoint : MonoBehaviour
6. {
7.    
8.      private void OnTriggerEnter2D(Collider2D collision){
9.          if(collision.CompareTag("Player")){
10.             PlayerPrefs.SetFloat("x",gameObject.transform.position.x);
11.             PlayerPrefs.SetFloat("y",gameObject.transform.position.y);
12.             PlayerPrefs.SetFloat("z",gameObject.transform.position.z);
13.          }
14.      }
15.    
16.      public void Update(){
17.  
18.        if(PlayerPrefs.GetInt("isRewarded")== 1  ){
19.  
20.             float x = PlayerPrefs.GetFloat("x");
21.             float y = PlayerPrefs.GetFloat("y");
22.             float z = PlayerPrefs.GetFloat("z");    
23.             GameObject.FindGameObjectWithTag("Player").transform.position = gameObject.transform.position;
24.             GameOverManager.instance.isRewarded = 0;
25.             PlayerPrefs.SetInt("isRewarded", 0);
26.         }        
27.     }
28.  
29. }
30.  

 

Lines 20 to 22 above... you get x,y,z to local variables, then do nothing with those values.

 

hey, yes somoene else told me the same thing, so i ve found a way and its work now, i ll put here :

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class takeCheckpoint : MonoBehaviour
6. {
7.    
8.      public Transform checkpoint;
9.    
10.      public float posX;
11.     public float posY;
12.      public float posZ;
13.  
14.      public void Start(){
15.  
16.              posX = checkpoint.position.x;    
17.              posY = checkpoint.position.y;
18.              posZ = checkpoint.position.z;
19.  
20.      }
21.      public void OnTriggerEnter2D(Collider2D collision){
22.          if(collision.CompareTag("Player")){
23.             PlayerPrefs.SetFloat("x",posX);
24.             PlayerPrefs.SetFloat("y",posY);
25.             PlayerPrefs.SetFloat("z",posZ);
26.             }
27.           }
28.  
29. }

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class CheckPoint : MonoBehaviour
6. {
7.     public takeCheckpoint positionCheck;
8.    
9.     public void Start(){
10.  
11.  
12.  
13.      }
14.    
15.      public void Update(){
16.  
17.        if(PlayerPrefs.GetInt("isRewarded")== 1  ){
18.          
19.             Debug.Log(positionCheck.posX);
20.  
21.             positionCheck.posX = PlayerPrefs.GetFloat("x");
22.             positionCheck.posY = PlayerPrefs.GetFloat("y");
23.             positionCheck.posZ = PlayerPrefs.GetFloat("z");    
24.             GameObject.FindGameObjectWithTag("Player").transform.position = new Vector3(positionCheck.posX,positionCheck.posY,positionCheck.posZ);
25.             GameOverManager.instance.isRewarded = 0;
26.             PlayerPrefs.SetInt("isRewarded", 0);
27.         }        
28.     }
29.    
30. }

thank you anyway
