Object.FindFirstObjectByType

Parameters

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.FindFirstObjectByType 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.FindAnyObjectByType

// Include inactive objects in search for CanvasRenderer
