SetActive doesn't activate a game object.

I have RoundManager script which's subscribed to the EnemyKilled event. Every time an enemy is killed it spawns an enemy on random spawn point. To spawn an enemy the RoundManager claims the enemy from the EnemyPool object. This's the EnemyPool's code snippet which returns the enemy:

Code (CSharp):

1. public IPoolMember SpawnEnemy(Vector3 position, EEnemies enemyType, bool setActive = true)
2. {
3.  
4.     IPoolMember spawnedEnemy;
5.     Transform enemyTransform;
6.  
7.     switch (enemyType)
8.     {
9.         case EEnemies.GrandmaEnemy:
10.             //If pool isn't empty
11.             if (_grandmaEnemyPool.Count > 0)
12.             {
13.                 //retrieve an enemy
14.                 spawnedEnemy = _grandmaEnemyPool.Pop();
15.             }
16.             else
17.             {
18.                 //else if pool is empty
19.                 //instantiate a new grandma enemy.
20.                 spawnedEnemy = InstantiateNewEnemy(enemyType);
21.             }
22.  
23.             //get transform component;
24.             enemyTransform = spawnedEnemy.GetTransform;
25.  
26.             //set position for enemy.
27.             enemyTransform.position = position;
28.             break;
29.          
30.  
31.         case EEnemies.RunnerEnemy:
32.             //If pool isn't empty
33.             if (_runnerEnemyPool.Count > 0)
34.             {
35.                 //retrieve an enemy
36.                 spawnedEnemy = _runnerEnemyPool.Pop();
37.             }
38.             else
39.             {
40.                 //else if pool is empty
41.                 //instantiate a new runner enemy.
42.                 spawnedEnemy = InstantiateNewEnemy(enemyType);
43.             }
44.  
45.             //get transform component;
46.             enemyTransform = spawnedEnemy.GetTransform;
47.  
48.             //set position for the enemy.
49.             enemyTransform.position = position;
50.             break;
51.  
52.         case EEnemies.AlphaEnemy:
53.             //If pool isn't empty
54.             if (_alphaEnemyPool.Count > 0)
55.             {
56.                 //retrieve an enemy
57.                 spawnedEnemy = _alphaEnemyPool.Pop();
58.             }
59.             else
60.             {
61.                 //else pool is empty
62.                 //instantiate a new alpha enemy
63.                 spawnedEnemy = InstantiateNewEnemy(enemyType);
64.             }
65.  
66.             //get transform component;
67.             enemyTransform = spawnedEnemy.GetTransform;
68.  
69.             //set position.
70.             enemyTransform.position = position;
71.             break;
72.  
73.         default:
74.             throw new UnityException(string.Format("Unknown enemy type: {0}.", enemyType.ToString()));
75.     }
76.  
77.     spawnedEnemy.GetTransform.gameObject.SetActive(setActive);
78.     return spawnedEnemy;
79. }

You can see that on the line 77 before returning the enemy, the EnemyPool activates it.
The problem is that sometimes the returned enemy is active sometimes it's not. I can't figure out why. I tried to debug the EnemyPool's SpawnEnemy method. I placed a breakpoint on the line 78, right on the return statement with the following condition:

spawnedEnemy.GetTransform.gameObject.activeSelf == false

and this is what got:
I can't figure out why it's deactivated?

 

Hey,

What does your IPoolMember interface look like?

 

Hi @ismaelflorit. Thank you for your attention but I already solved the problem. Turned out the problem was in the FSM logic. After enemy was killed. returned back to the pool and then retrieved from the pool, it still remained in the Death state. The Death state was deactivating the enemy after it was retrieved from the pool.
