The method GameObject.FindGameObjectsWithTag("name") is only searches current player(owner)'s objects, but I need all gameobjects with one tag no matter whose those gameobjects.
Thanks in advance!

Actually GameObject.FindGameObjectsWithTag("name") should search the whole scene for the Tag, are you sure those objects in question have the tags assigned to them?
