Triggered Doors and Triggered Bosses?

[eluzai777]

I cant find a guide neither have i figured it out on my own how to:

1. Have Doors in instances(such as Blood Furnace or Utgarde Pinnacle) to activate after killing a boss.

2. Have Bosses non targeted, non selectable, or just not hostile until mobs in area are all killed.

3. Have something trigger such as a sound entry when character enters an area

Are these sort of triggers possible with LUA or in the Database? If anyone has a guide on these topics i would greatly appreciate it.

1 and 3 are LUA

Its Lua, not LUA. And I think all 3 can be done by C++ scripting.

1. OnDied(unit * mKiller)
2. .No clue about that one..
3. You could use a hook for that one such as

SERVER_HOOK_EVENT_ON_ZONE

2. C++, search for creature flags. There's a flag for not selectable, and faction 35 is friendly to all
