Public Function Issue

Hello! I am trying to create a real simple public function to replace the already complicated quest icon system I made on lexia. Here is what I want to do. I want to create a public function in my npc class named, icon...

PHP Code:


		
			
public function QuestIcon(icon_text) {

  if (playertouchsme) {

    say2(icon_text);

  }

}

I am getting no success though when joining the class to the npc...

PHP Code:


		
			
join("icon")

then using the function...

PHP Code:


		
			
QuestIcon("My name is bob");

Here is what I am doing...

PHP Code:


		
			
function onCreated() {

  join("icon");

}

if (playertouchsme) {

icon.QuestIcon("MOO");

}

Anybody got any ideas?

I don't think you understand what you're actually trying to do, what public functions are for, or how classes work.

Perhaps this is what you're trying to do:

Level NPC:

PHP Code:


		
			
function onCreated() {

  this.quest_text = "My name is bob";

  join("icon");

}

class: icon

PHP Code:


		
			
function onPlayerTouchsMe() {

  say2(this.quest_text);

}

A public function is for allowing other scripts to use the function remotely. I.e:

Level NPC A:

PHP Code:


		
			
function onCreated() {

  this.level.cat = this;

}



public function meow() {

  echo("Meow");

}

Level NPC B:

PHP Code:


		
			
function onCreated() {

  if (this.level.cat == NULL) {

    waitfor(this, "LetCatLoad", 0.05);

  }

  temp.cat = this.level.cat;

  temp.cat.meow();

}

A class basically pastes code/functions into an NPC, onCreated is called in the class when it's joined.

Also, never use if (playertouchsme).

or any other flag that's now a function/event. (playerchats, playerenters, etc.)

It's probably useful to point out why the above two posts are true:

There was a previous version of GScript which was less powerful than the current. The current language retained backwards compatibility so that older scripts wouldn't completely break. It's bad practice to use the old version whilst the new one is available.

I think a simple analogy works here. When the PS2 was released, it was possible to play PS1 games on it, which was great because many people still had PS1 games they loved to play. The PS1 games were ugly in comparison to their PS2 counterparts and they are rarely played nowadays. Folk that still do are are either looking for nostalgia (a percentage of which become disappointed fairly quickly) or they picked up an older PS1 version of a PS2 game on eBay by accident. The latter type gets ridiculed from their peers for mistakingly buying and playing the older version of the game.

The default level editor is the PS1, a rented server a PS2, GScript 1 is an old PS1 game and GScript 2 is a PS2 remaking of the same game. It should be obvious from here!

I think at this point in time Graal is still waiting for its PS3? Some would argue a different type of console altogether.

Graal isn't in desparate need of a new scripting language. GS2 has plenty of flaws, but it needs changes, not to be completely thrown out.

Stefan was experimenting with JavaScript as a serverside language, though, but I haven't heard anything about it in the past year. If JS was used, it might be possible for him to use an existing JavaScript engine like V8 (which uses JIT compilation) for massive speed improvements (not that they're really needed on serverside).

This was simply speculation. I haven't been back long enough to know the sentiments towards GS2 these days. I remember Inverness was pretty heavy on making all scripters Pythonistas.

I'd love to know more about that. Speed improvements are the last thing on the list here. CoffeeScript perhaps?

I knew this already, I was being lazy and saving me a few seconds. Sorry lol. Thank you to everybody that helped though!

Please refer to the last part of my analogy:
