remove empty array element unity code example

Example 1: unity clear array

for (int i = 0; childs.Length; i++) {    childs[i] = null // or    childs[i] = 0;   }

Example 2: remove empty values from array unity

int LevelSelection;     [HideInInspector] public GameObject[] disabledMap;     void LoadLevel()     {         //sets the disabled array to the amount of map sections         disabledMap = new GameObject[LevelObjects.Length];          int dissabledArrayCount = 0;         //iterates through all map sections         for (int i = 0; i < LevelObjects.Length; i++){             //checks if current iteration is enabled             if (LevelObjects[i].activeSelf == false)             {                 //if the map section is enabled it adds it to a separate array.                 disabledMap[dissabledArrayCount] = LevelObjects[i];                 dissabledArrayCount++;                 print("added to array.");             }         }         //debug         print("Length :" + disabledMap.Length);          //Clears empty indexes here.          //chooses a random map section from the array of disabled map sections.         int levelChoice = Random.Range(0, disabledMap.Length);         print("Level choice :" + levelChoice);          disabledMap[levelChoice].SetActive(true);         disabledMap[levelChoice].transform.position = new Vector3(0, 0, LastLoad + 30);      }

Example 3: remove empty values from array unity

GameObject[] gameObjectArray = new GameObject[] { new GameObject(), new GameObject(), new GameObject() }; // example GameObject Array List<GameObject> gameObjectList = new List<GameObject>(gameObjectArray); gameObjectList .RemoveAll(x => x == null); gameObjectArray = gameObjectList .ToArray();
