[GUI] - Check if an shop item are already bought.

qgouty · Apr 29, 2014

Hi everyone,

Actually, I'm working on a GUI javascript for a shop. I want that if I bought an item, a message say like : "Congragulation. You have bought this item". And if I try to bought the same item again, a others message say like : You can't buy it. You have already bought it".

I've souht a lot of methods, with booleans or others but it's not working.
Please tell me if you have find a method for that.

For clarification, I have a nearly 50 item to check

Thanks for advance.

P.S : I've don't put it to Unity Aswers. It has a bug for tags

How are you trying to do it at the moment? It depends on a lot of things, like how other parts of your game work.

As a complete stab in the dark, you could make a MonoBehaviour called "PurchasedItemList" and attach it to your player(s). You can give it a List<...> of item IDs or item references or whatever you're using to define items in your shop. (You haven't told us, so can't really be more specific.) You then have public methods "AddItem", "RemoveItem" and "HasItem" which map directly to available methods on the List<...>. Then, when the player tries to purchase something from the shop, you first call HasItem(theItem) to see if the player has already got it. If they do not, then you call AddItem(theItem) when the purchase is confirmed. If an item can ever get un-purchased or lost or consumed or whatever then you can also call RemoveItem(theItem).

Also, it doesn't sound like it's a bug, which might put people off giving you an answer at the Answers site.

I don't understand "AddItem", RemoveItem" ect.. can you exlain please ?
Thanks for advance

Click to expand...

Hmm.

Please don't take this the wrong way... After seeing the above code, I strongly suggest learning some more about programming before carrying on with this task. Learn about arrays, collections, classes and functions as a minimum, and this task will suddenly seem far easier.

Generally speaking when programming, if you find yourself writing out lots and lots of similar stuff by hand then you're not using the right tool for the job somewhere. In this case you're only using one or two really basic tools, and you're trying to use them to do tasks with brute force that other tools (the 4 things I mentioned above) could achieve far more easily, in a more robust, easy to maintain manner.

If the above is a challenge then expanding out to an entire online game is going to be nearly impossible.

Thanks for yours advices, I'm learning about unity scripting. Sorry if I you're pissed, I don't understand what you said at your first post : I'm a french yong man...
And, for class, i've already try. I don't know why unity does not take into account variables in class.

For example, if I write somethig like :

Code (csharp):

class test extends System.Object (

var var1 : String;

enum test (1,2,3);

var var2 : test;

)

var Test : test;

function Update () (

if (Test.var2.1) (

print ("Something");

)

)

It doesn't work...

Hey man, angrypenguin isn't pissed hehe, he's just trying to help you...
About your code, he was referring to Lists, not Enums.

Let me try helping you with this.

First you need to import the right library for this

Code (csharp):

using System.Collections.Generic;

and than, you need to initialise your List

Code (csharp):

public List<Item> ItemsBought = new List<Item>();

and here, is the part where u should add the item every time you buy something

Code (csharp):

ItemsBought.Add(itemToBeBought);

but... before buying the item, you should check the list to see if the player already have the item, so, it's something like this

Code (csharp):

if(ItemsBought.Contains(itemToBeBought)){

//let the player know that he already have the item

}else{

ItemsBought.Add(itemToBeBought);

}

well... i hope that helped you in some way

Btw.... if you want to remove an item from the list:

Code (csharp):

ItemsBought.Remove(item)

or if you want to remove by index

Code (csharp):

ItemsBought.RemoveAt(index)

I'm not pissed (or angry) at all. Just trying to point you towards a better path, that's all.

The class you've got there isn't written correctly. Alas, my telling you how to correct it won't help you in the long run. You've got to learn and understand it for yourself. If you've got specific questions for your learning or are trying to solve a particular problem then the community here rocks and will help you out. You have to learn the basics for yourself though, that's not something we can give you piece by piece.

Where are you learning from? Some resources are better than others, we might be able to help out by making sure you're using the better stuff.

Thanks for your advices angrypenguin and mukagbr. I precisely search it. If I don't understand what I write, it will be hard to develop my game....

I'm looking for youtubes channels tutorials, but the betters are in english... If I don't understand all the persons say, i can't learn.

Thanks again for advices and explications ( I didn't know that lists exist... I'm in the ignorance) .

Just a final question : Are we obliged to write hooks for "if" and "else", because I noticed that some people do it, in C# ?

Thanks again, I am very grateful to you. Good developping, teaching, or wahtever you do...

By "hooks" do you mean braces? These things?

Code (csharp):

{ }

They define a new "scope" or "block" of code. When you write an "if" statement, if it evaluates to 'true' then the following block or statement is executed. This means that they're optional if you only need to control execution of a single statement, but they're a requirement if you want to control more than one.

This...

Code (csharp):

if (x > 0) x = x - 1;

... is the same as ...

Code (csharp):

if (x > 0)

x = x - 1;

... is the same as

Code (csharp):

if (x > 0) {

x = x - 1;

}

However, this...

Code (csharp):

if (x > 0)

x = x - 1;

y = y + 1;

... is different to this:

Code (csharp):

if (x > 0) {

x = x - 1;

y = y + 1;

}

Note the spacing, how the "y = y + 1" line is indented differently in the two examples. White space is ignored by the compiler, but it's really useful to us human beings when we keep it nice and organised like that because it helps us see at a glance how things execute.

Thanks AngryPenguin, for your great answer, so if i understood, the brackets define just "if" statement limitations.

Thanks for all

P.S : sorry for my bad english and translation...
