writing to an npc flag from class?

i've done it before, but for some reason it just won't work properly

npc vardump:

PHP Code:


		
			
Variables dump from npc boolean

boolean.type: SYSTEM
boolean.scripter: boolean
boolean.level: onlinestartlocal.nw

Attributes:
boolean.image: 
boolean.script: size: 0
boolean.visibility flags: visible
boolean.id: 1014
boolean.sprite: 2
boolean.head: 
boolean.xprecise: 0
boolean.yprecise: 0

this.-Flags
boolean.vote=12

class:

PHP Code:


		
			
function onCreated(){
  boolean.vote[0] = 1;
  sendtonc(boolean.vote[0]); // outputs 12 instead of 1
}

help is appreciated

  sendtonc(boolean.vote[0]); // outputs 12 instead of 1

}

To write "vote[0]", vote would need to be initialized as an array first, such as:

PHP Code:


		
			
//boolean.vote = new[array size];

boolean.vote = new[2];

PHP Code:


		
			
boolean.vote = {NULL, NULL};

For whatever reason I'm having trouble just adding to the array.

PHP Code:


		
			
function onPlayerChats(){
  if(player.chat == "/b"){
   boolean.vote = new[boolean.vote.size() + 1]; 
   boolean.vote[this.boolean.vote.size() + 1] = 45;
   player.chat = boolean.vote[boolean.vote.size()];
  }
}

Will return 45 once, the other values are NULL. Other than that, it works quite nicely.

The new[] keyword will create a completely new array. You can't expand existing arrays with it. Also, you should use the array size minus one when assigning something to the last index/field, since it starts at 0.

Not sure if it's necessary, but I always create arrays with a dynamic size like this:

PHP Code:


		
			
temp.array = {};

temp.array = new[]; // I believe this is also possible

You're also missing some this. prefixes in your code (that, or you got one where you don't want one).

Haha, yeah. I'll try that.

PHP Code:


		
			
  boolean.vote = {player.account};
  player.chat = boolean.vote[boolean.vote.size() - 1];

How would I make boolean.vote = {}; expand?

You can use temp.array.add(element).
