Arrays...?

[Shard_IceFire]

Hi!
I am a pretty good scripter, but one thing that I just skipped over when I was learning was arrays. I was wondering, exactly how do you use them? And what can they be used for?
Thanks.

they are used for storing more than one thing in a variable. it would be like hearts(1) and hearts (2) but the variable would just be hearts but it breaks it up into parts

well a basic array would be like

NPC Code:

---

if(created){

  this.x={1,30,50,25};

  this.y={5,20,18,30};

}

if(playertouchsme){

  this.rnd=int(random(0,4));

  x=this.x[this.rnd];

  y=this.y[this.rnd];

}

whats:

if(created){
this.x={1,30,50,25};
this.y={5,20,18,30};
}

for?

same thing as if you did
this.x[0]=1
this.x[1]=30
this.x[2]=50
this.x[3]=25

Maybe my mistake, but don't you need setarray this.x 4; in front of that?

yes

doing this.array={1,2,3,4}

is far more efficient

'Tis generally what I do, unless I want the array to have a 'variable' length

say you have prices for different apples

you could do this:

this.appleprices={30,40,50,50}

then call it like this:

players[0].rupees-=this.appleprices[this.appletype];

which would be far more efficient than
having variables for each apple price and
would be easy to customize if you had at
the beginning of a script

I still don't quite get that....
rupees-=this.appleprices[this.appletype];
does it just choose one of the 'appleprices' numbers at random or something?
