C0246 error

i am new to unity but i know quit a bit so i was coding something and i got CS0246 error and i dont get what the problem is and it says the error is on line (7,12) but there is nothing wrong what can i do to fix it?????? here is my code



using System;
using System.Collections;
using System.Collections.Generic;
public class Data

public class data
{
public BigDouble Coins;

public BigDouble ClickUpgradeLevel;

public Data()
{
Coins = 0;

ClickUpgradeLevel = 0;
}
}

 

as you can see, you repeat your class creation

Code (CSharp):

1. public class Data
2.  
3. public class data

 

thats not the probem i just typed it wrong and put 2 class data by accident but the u know the actual problem?

 

remove "public class Data" on line 4

and i think the class name should start with a big letter.

Please post the next time, the full error message and not only the id and use code tags, to make it more readable

 

The double class is part of your problem. You have no {} for the first data class. Also, what is Public Data()? I would recommend you view the following

Unity C# Survival Guide - Unity Learn

 

the type or name space 'BigDouble' could not be found

 

Rather than these forums being your "fix one error and read back the next error" service, you can actually reason about errors and solve them all by yourself... It's amazing!

In this case it sounds like you're using something that is not part of Unity. Perhaps you need to get that BigDouble from some library? Google might be useful here.

If you post a code snippet, ALWAYS USE CODE TAGS:

So, where in your code where you define what a "BigDouble" is?
