Declaration

public static T FindFirstObjectByType();

Declaration

public static T FindFirstObjectByType(FindObjectsInactive findObjectsInactive);

Declaration

public static Object FindFirstObjectByType(Type type);

Declaration

public static Object FindFirstObjectByType(Type type, FindObjectsInactive findObjectsInactive);

Parameters

type The type of object to find.
findObjectsInactive Whether to include components attached to inactive GameObjects. If you don't specify this parameter, this function doesn't include inactive objects in the results.

Returns

T Returns the first active loaded object that matches the specified type. If no object matches the specified type, returns null.

Description

Retrieves the first active loaded object of Type type.

Object.FindFirstObjectOfType doesn't return Assets (for example meshes, textures, or prefabs), or inactive objects. It also doesn't return objects that have HideFlags.DontSave set.

Note: This function is very resource intensive. It's best practice to not use this function every frame and instead, in most cases, use the singleton pattern. Alternatively if you only need any instance of a matching object rather than the first one you can use the faster Object.FindAnyObjectOfType
