getting an index

I'm having a little trouble here.

I'm making a bounty system, the account and the amount of money for that bounty will be placed in an array like this:

this.bounty = {{"Frankie", 2000}, {"TSAdmin", 1500}};

when a player dies I want to check if they are in the list, but I can't do that because I'm having trouble checking the index.

function onCreated()
{
this.array = {{"Frankie", 2000}, {"TSAdmin", 1500}};
this.getIndex = this.array.index("Frankie");
sendtorc(this.getIndex);
}

returns -1.

I need it to return 0 this way I can do:

this.moneyAmount = this.array[this.getIndex][1];

there's something I'm missing but TSA and I can't figure it out.

Try maybe:

PHP Code:


		
			
temp.array = {{"Frankie","TSAdmin"},{2000,1500}};

temp.ind = temp.array[0].index("Frankie");

echo(temp.ind);

echo(temp.array[1][temp.ind]);

The way you're doing it will not work; you can loop through the elements to find the right index, like so:

PHP Code:


		
			
temp.array = {{"Frankie",2000},{"TSAdmin",1500}};

temp.l = temp.array.size();

for (temp.i=0;temp.i<temp.l;temp.i++)

  if (temp.array[temp.i][0] == "Frankie") {

    echo(temp.i);

    break;

  }

echo(temp.array[temp.i][1]);

By my best estimates (read: guess), the former is ~2.5x faster.

You can't get the index of a subaray in an array without a loop.

PHP Code:


		
			
// ...

this.array = {{"Frankie", 2000}, {"TSAdmin", 1500}};
this.getIndex = index2(this.array, "Frankie");
echo(this.array[this.getIndex][0] SPC "found!");

// ...

function index2(array, acc)
{
  for (temp.arg: array) {
    if (temp.arg[0] == acc) return array.index(temp.arg);
  }
  return -1;
}

EDIT: Bah, Pfa beat me too it!

You're probably better off just storing them all in variables like:

PHP Code:


		
			
this.bountylist.Frankie = 2000;
this.bountylist.TSAdmin = 1500;

temp.foo = this.bountylist.(@ player.account);
echo("My bounty is " @ foo);

You can also transfer the list by use of:

PHP Code:


		
			
this.bountyarray = this.bountylist.savevarstoarray(true);

And:

PHP Code:


		
			
this.bountylist.loadvarsfromarray(this.bountyarray);
