Script doesn't work - Tuv - 28.12.2015

Hello, please help me understand what did I do wrong with this code, I don't know why draw and messages "VISMENU HIDDEN" and "VISMENU SHOWN" don't appear.

I'm not very familiar with classess but this is basically a copy-paste of script "statistics.nut".

I think I made this work. Try that:

Thank you! I've tried everything but I've missed it

If you using class you have to remember, that any class vars, must be initialized in class constructor, and before initializing they have to be declared.

So for example:
Squirrel Script
  1. class Foo
  2. {
  3. 	constructor()
  4. 	{
  5. 		var1 = "Var 1";
  6. 		var2 = 921323;
  7. 	}
  8.  
  9. 	var1 = null;
  10. 	var2 = null;
  11. 	var3 = null; // This one isn't initialized so will be static member of this class
  12. };

Yes,  I know that already, and actually I wonder why i can't make class like this


Code:
class Foo
{
    constructor()
    {
        table = {};
        table[1] = "Hello";
        table[2] = "XASDASDADSa";
        table[3] = 22;
    }

    for(local i = 1; i < 3; i++)
        table[i] = null;
};

compiler says: expected 'IDENTIFIER'

Becasue doing this u spoil sytax of the class. Compiles says, that he wait for some identifier, which wasn't founded. In ur case u used reserved name table.

The correct way is:
Squirrel Script
  1. class Foo
  2. {
  3.     constructor()
  4.     {
  5.         _table = [];
  6.         _table.append("Hello");
  7.         _table.append("XASDASDADSa");
  8.         _table.append(22);
  9.         // Or
  10.         /*
  11.         _table = array(3); // Array size 3
  12.         _table[1] = "Hello";
  13.         _table[2] = "XASDASDADSa";
  14.         _table[3] = 22;
  15.         */
  16.     }
  17.  
  18.     _table = null;
  19. };



In squirrel we have array, and tables. They are different containers of data.

EDIT. If you really want to use tables then here is an example:
Squirrel Script
  1. class Foo
  2. {
  3.     constructor()
  4.     {
  5.         _table = {};
  6.         // Only way is create slot, and now will work
  7.         _table[1] <- "Hello";
  8.         _table[2] <- "XASDASDADSa";
  9.         _table[3] <- 22;
  10.  
  11.         // Slot can be deleted with keyworld delete slot;
  12.     }
  13.  
  14.     _table = null;
  15. };
