Problem using a level NPC that's joined to a class

[fowlplay4]

Here's one way of doing it, you assign a shop id to your npc.

I.e: this.shop_id = "basicshop";

PHP Code:

function onCreated() {
  this.shop_id = "basicshop";
  this.join("shopkeeper");
} 


DB-NPC: DB_Shops (For this example)

PHP Code:

function onCreated() {
  // Setup Basic Shop's Item List
  this.shop_basicshop = {
    {"Fireball", "split_fireball", "split_fireball.png", "split_fireball_selected.png", 30}, 
    {"Sword", "split_sword", "split_sword.png", "split_sword_selected.png", 20},
    {"Bow", "split_bow", "split_bow.png", "split_bow_selected.png", 10}
  };
}

// Public method to retrieve the items for a specific shop
public function getShopItems(shop_id) {
  return this.("shop_" @ shop_id);
} 


then in your NPC:

PHP Code:

// other code..

function getShopItems() {
  return DB_Shops.getShopItems(this.shop_id);
}

function onPlayerTouchsMe() {
  // You don't need to specify "gui", you can just use the weapon's name.
  player.triggerclient("-shopcontrol", this.shop_id, getShopItems(), this.x, this.y);
} 


Then in your script you can just store the shop id, and display the items, and then trigger your DB-NPC, verify the purchase against the list of items for that shop, and allow the player to purchase the item.

Thank you I tried something similar just now, but failed because I didn't make the function getItems in the DB NPC public. I suppose it has to be public?

To call it from other scripts like in my class example, yes.

Thank you very much! Now I think I understand the DB NPC

Although, I still have problems with the PlayerTouchsMe. It seems as if the player touches the NPC when the player is located to the top left of the NPC.

This is the NPC script:

PHP Code:

join("shop");

//#CLIENTSIDE

function onCreated()
{
  showcharacter();
  nick = "Candy"; //Sets the nickname of the character
  ap = 100; //Sets the ap of the character. Also affects the colour of the nickname
  headimg = "head722.gif"; //What head image to use
  bodyimg = "body8.png";   //What body image to use
  colors[0] = "orange";     //Sets the skin colour
  colors[1] = "lightblue";     //Sets the coat colour
  colors[2] = "yellow";     //Sets the sleeves colour
  colors[3] = "darkred";     //Sets the shoes colour
  colors[4] = "lightgreen";     //Sets the belt colour
  shieldimg = "no-shield.gif"; //Sets the shield image
  shieldpower = 1; //Must have this or the shield won't show

} 


and this is the shop class:

PHP Code:

function onCreated()
{
   setShape(1, 32, 32);
   this.shop_id = "basicshop";
}

function onPlayerTouchsMe()
{
  this.listofitems = DB_Items.getShopItems(this.shop_id);
  triggerclient("gui", "-shopcontrol", this.listofitems, this.x, this.y);         
} 


Am I missing something that causes the PlayerTouchsMe to fire when I'm located to the top left of the NPC?
