Pooling object and make it disappear as it collected

Hello guys,

I am new to Unity. I am following this session to making a flappy bird style game in this link https://learn.unity.com/tutorial/live-session-making-a-flappy-bird-style-game
I want to add coin in my game,it will appear randomly and disappear as it collected. How can I do it.
Thank in advance

 

Hi ddtna

I posted a reply that includes scripts and screenshots that answers your question.

You would create this script and attach it your coin

Code (CSharp):

1. using UnityEngine;
2. public class Cash : MonoBehaviour
3. {
4.     // this is just an object to store money
5.     public ProtoMoneyManager protoMoneyManager;
6.     public float cashValue = 15;
7.     public string player = "Player";
8.     private void Awake()
9.     {
10.         protoMoneyManager = FindObjectOfType<ProtoMoneyManager>();
11.     }
12.     private void OnTriggerEnter(Collider other)
13.     {
14.         if (other.CompareTag(player))
15.         {
16.             protoMoneyManager.AddMoney(cashValue);
17.             Destroy(this.gameObject);
18.         }
19.     }
20. }

In this script add the money to your ui.text or what ever.

Code (CSharp):

1. using UnityEngine;
2. public class ProtoMoneyManager : MonoBehaviour
3. {
4.     public UI.Text txtMoney;
5.     public float money;
6.     void Start()
7.     {
8.         DontDestroyOnLoad(gameObject);
9.         money = 100;
10.     }
11.     public float GetCurrentMoney()
12.     {
13.         return money;
14.     }
15.     public void AddMoney(float cashValue)
16.     {
17.         if (GetCurrentMoney() + cashValue <= 9999 - cashValue)
18.             money += cashValue;
19.  
20.           txtMoney.text = money;
21.     }
22. }

 

here are my codes. It only able to creat 5 coins, when i collected all of it the game stop.
but if i raise coinsPoolSize, the game doenst work either.
I want to spawn the coins when I play it and be able to collect. How can I make it works?

Code (CSharp):

1. public class Coin : MonoBehaviour
2. {
3.  
4.     void OnTriggerEnter2D(Collider2D other)
5.     {
6.         if (other.GetComponent<Ufo>() != null)
7.         {
8.             GameControl.instance.UfoScored();
9.             Destroy(gameObject);
10.         }
11.     }
12.      
13. }

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class CoinPool : MonoBehaviour
6. {
7.     public GameObject CoinsPrefab;                                  
8.     public int coinsPoolSize = 5;                                  
9.     public float spawnRate = 2f;                                  
10.     public float monstersMin = -1f;                                  
11.     public float monstersMax = 3.5f;                                  
12.  
13.     private GameObject[] coins;                                  
14.     private int currentCoins = 0;                                  
15.  
16.     private Vector2 objectPoolPosition = new Vector2(-10, -15);      
17.     private float spawnXPosition = 4f;
18.  
19.     private float timeSinceLastSpawned;
20.  
21.    
22.     void Start()
23.     {
24.         timeSinceLastSpawned = 0f;
25.  
26.        
27.         coins = new GameObject[coinsPoolSize];
28.      
29.         for (int i = 0; i < coinsPoolSize; i++)
30.         {
31.            
32.             coins[i] = (GameObject)Instantiate(CoinsPrefab, objectPoolPosition, Quaternion.identity);
33.         }
34.         InvokeRepeating("CoinPool", 2.0f, 0.3f);
35.     }
36.    
37.  
38.    
39.     void Update()
40.     {
41.         timeSinceLastSpawned += Time.deltaTime;
42.  
43.         if (GameControl.instance.gameOver == false && timeSinceLastSpawned >= spawnRate)
44.         {
45.             timeSinceLastSpawned = 0f;
46.  
47.          
48.             float spawnYPosition = Random.Range(coinsMin, coinsMax);
49.  
50.          
51.             coins[currentMonsters].transform.position = new Vector2(spawnXPosition, spawnYPosition);
52.  
53.            
54.             currentCoins++;
55.  
56.             if (currentCoins >= coinsPoolSize)
57.             {
58.                 coinMonsters = 0;
59.                 Destroy(gameObject);
60.             }
61.         }
62.     }
63. }
