Simple level restriction

Heya, i was wondering if you guys could help me with this. Im making a simple lvl restriction system, but i want it to be easily editable with account names that can access it. First i thought if i use a weapon as a keycard and if the player doesn't have the weapon, he/she will be warped elsewhere but its not efficient enough. Any ideas?:noob:

Use a database NPC to store flags of rights within the level, including who can access it.

You could simply make a class holding the restriction and a list of accounts, and join it to the level.
EDIT: Or what TSA said

I am new to scripting and, i know what your saying, but i don;t know where to start doing that. I like the use of a database NPC to keep it simple but any advance on that?
Most appreciated.

I'm not positive this is what you're looking for but there is a tutorial in the wiki explaining how to make database NPC's.

Ignore Bell's post (sorry Bell), that's not relevant to what you want to do.

If you create a database NPC named, say, AccessControl, you can access public functions in the script simply by calling them from any serverside script:

PHP Code:


		
			
AccessControl.myFunction();

Inside the AccessControl script, you'd want to have something like this:

PHP Code:


		
			
public function addAccountToLevel(levelName, account) {
  this.access.(@ levelName).add(account);
  this.save();
}

public function removeAccountFromLevel(levelName, account) {
  this.access.(@ levelName).remove(account);
  this.save();
}

public function accountHasAccess(levelName, account) {
  return (account in this.access.(@ levelName));
}

// this seems to prevent the DB NPC from rolling back
function save() {
  this.trigger("update");
}

Now you'll want to place a script inside the level that allows you to control this. You don't have to do it by level, either, as long as you're using something consistent like "house_cbk1994" throughout all levels you want to have the same access.

An example of the level script:

PHP Code:


		
			
function onPlayerEnters() {
  if (! AccessControl.accountHasAccess(this.level.name, player.account)) {
    player.chat = "I'm not allowed here!";
    player.setLevel2("osl.nw", 32, 32);
  }
}

Quite alright Chris, I was attempting to guess what he was hunting for. I knew someone would correct me if I was wrong :D.

Thanks CBK. I know know that DPNCS can be used for much more than storing data. Thanks. Im not gonna copy and past the script but use it as a template for my own. That way i will learn more and be happier with the outcome, if any. Thanks guys.
