Unity Engine

hey guys! its been a while since i last asked anything in here, i realy though that i could go on alone by now, but… i guess i’ll be asking here forever because something new aways pop up when i am making my game >.<

i wanted to ask… how do enable and disable all gameobjects in the sceene that has a certain tag? … is there a way to do this? a script that looks trough all objects even the ones that are not activated looking gor their tags, and when it finds a certain tag, it activates (or enable) then?

var player = GameObject.FindWithTag("Player");

read http://unity3d.com/support/documentation/ScriptReference/index.Accessing_Other_Game_Objects.html then basically do something like player.active =false or player.enabled=false to disable it
