Close| value | The active state to set, where true sets the GameObject to active and false sets it to inactive. |
Activates or deactivates the GameObject according to the value of the supplied parameter.
SetActive only sets the local state of the GameObject, represented by the value of GameObject.activeSelf. It does not activate a GameObject for which GameObject.activeInHierarchy is false because a parent object in the Scene hierarchy is inactive.
Deactivating a GameObject disables each component, including attached renderers, colliders, rigidbodies, and scripts. For example, Unity will no longer call MonoBehaviour.Update on a script attached to a deactivated GameObject. Deactivating a GameObject also stops all coroutines attached to it.
Calling SetActive with a value of true callsMonoBehaviour.OnEnable on scripts attached to the GameObject, while calling SetActive with a value of false calls MonoBehaviour.OnDisable.

public class Example : MonoBehaviour { private GameObject[] cubes = new GameObject[10]; public float timer, interval = 2f;
void Start() { Vector3 pos = new Vector3(-5, 0, 0);
for (int i = 0; i < 10; i++) { cubes[i] = GameObject.CreatePrimitive(PrimitiveType.Cube); cubes[i].transform.position = pos; cubes[i].name = "Cube_" + i; pos.x++; } }
void Update() { timer += Time.deltaTime; if (timer >= interval) { for (int i = 0; i < 10; i++) { int randomValue = Random.Range(0, 2); if (randomValue == 0) { cubes[i].SetActive(false); } else cubes[i].SetActive(true); } timer = 0; } } }
