Database errors

I am following a tutorial by AwfulMedia and I am getting 4 errors for one simple part of the script.

Here is the code:

Code (CSharp):

1. void ConstructItemDatabase()
2.     {
3.         for (int i = 0; i < itemData.Count; i++)
4.         {
5.             database.Add(new Item(
6.                 (int)itemData[i]["id"],
7.                 itemData[i]["title"].ToString,
8.                 (int)itemData[i]["value"],
9.                 (int)itemData[i]["stats"]["power"],
10.                 (int)itemData[i]["stats"]["defence"],
11.                 (int)itemData[i]["stats"]["vitality"],
12.                 itemData[i]["description"].ToString,
13.                 (bool)itemData[i]["stackable"]));
14.         }
15.     }

and here are the errors I am getting:
error CS1502: The best overloaded method match for `Item.Item(int, string, int, int, int, int, string, bool)' has some invalid arguments

error CS1503: Argument `#2' cannot convert `method group' expression to type `string'

error CS1502: The best overloaded method match for `System.Collections.Generic.List<Item>.Add(Item)' has some invalid arguments

error CS1503: Argument `#1' cannot convert `object' expression to type `Item'

Any help would be really appreciated!

 

I think you are missing brackets after ToString on line 7, it should be

Code (CSharp):

1. itemData[i]["title"].ToString(),

and the same on line 12

Code (CSharp):

1. itemData[i]["description"].ToString(),

 

That was it,
Thanks!

 

I am now having another error

Code (CSharp):

1. KeyNotFoundException: The given key was not present in the dictionary.
2. System.Collections.Generic.Dictionary`2[System.Int32,System.Int32[]].get_Item (Int32 key) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.Collections.Generic/Dictionary.cs:150)
3. LitJson.JsonReader.Read ()
4. Rethrow as JsonException: Invalid token '58' in input string
5. LitJson.JsonReader.Read ()
6. LitJson.JsonMapper.ReadValue (LitJson.WrapperFactory factory, LitJson.JsonReader reader)

11. LitJson.JsonMapper.ToObject (System.String json)
12. ItemDatabase.Start () (at Assets/Scripts/GUIScripts/ItemDatabase.cs:14)

Here is my entire code:

4.         "title": "Pot",
5.         "value": 6,
6.         "stats": [

I started on that tutorial but.. I simply abandoned it. If you are going to be using an online database, the JSON database will be useless.
It just seems messy and overly complicated to me.

 

Did you find you did not like the JSON or that it did not work?

I find I like JSON quite a bit but that is just my personal preference

 

It didn't work. I've got an online database, so having a local item database is redundant. Also, I couldn't get Visual Studios to format the JSON which really hampered my desire to attempt using JSON

 

what are you using instead SQL?

 

Yeah, with a database manager in between the database and the client to handle any commands and prevent SQL injections or intrusions.

 

[/QUOTE]

Oh I figured out the error. For anyone else who got this error the error was in the json data with the array, if you take out the array every thing works fine.

Good Idea I may use this method instead

 

Hi There,

I am having some trouble with the awful media inventory tutorial. I have already posted to the forum:

http://forum.unity3d.com/threads/in...in-unity-5-by-awfulmedia.355047/#post-2751050

If any of you would glance over my problem and suggest solutions I would be grateful.

Cheers!
