quick scripting question

Hello.

Say I wanted to make a bank and the account script was going to go into npc-control. What would I put in that specified object to join it to an npc?

like when its a class, you would do:

join (classname);

is it :

join (npcname);

?

thanks,

jamerson

The only thing that can be in a join() is a class.

I'm not quite following what you want, can you be more specific?

You mean a DB-NPC?

I tend to think of classes as "function packs" for existing npcs, but here's an example of how they work. ( I assume that what's you don't understand. )

Class: example

PHP Code:


		
			
function randomClassFunc() {
  echo("success!");
}

Then in your DB-NPC:

PHP Code:


		
			
function onCreated() {
  join("example");
  randomClassFunc(); // Would echo "success!" on NC.
}

Also, it is
join("classname");
not
join (classname);
Firstly, join, like other functions, should not have a space between the function name and the parenthesis. Secondly, you must enclose strings(like the name of a class or weapon) in quotation marks, or else Graal will be trying to find a variable.

What im asking is how do you make a level npc have the same function as the db-npc. Its a bank system, and when you update the level the bank account money n your account resets, thats why i want to use a db npc. How do I make the npc in the level use the script thats in a db npc?

Oh well there's public functions.

In your DB-NPC (named Example in this case):

PHP Code:


		
			
public function onRandFunc() {

  echo("success!");

}

Then in your level npc:

PHP Code:


		
			
function onCreated() {

  findnpc("Example").onRandFunc(); // Would echo success! on RC

}

No reason at all to use findNPC.

PHP Code:


		
			
Example.func();

Personal preference. I use it for code readability.

I use it because I have trust issues with variable names.

You can also do a class like this:

PHP Code:


		
			
function hello() {
  echo("hello from class");
}

then a script like this:

PHP Code:


		
			
function onCreated() {
  join("classname");
  classname::hello();
  hello();
}
function hello() {
  echo("hello from script");
}

This way you can ensure that you're calling the function in the class.
