Is there any way you can possibly identify an argument's type. Currently i am only working on single index arguments, no arrays.

So if i have a function like this:

pawn Код:

MyFunc({_, Float}:...)
{
}

How can i do such thing:

pawn Код:

MyFunc({_, Float}:...)
{
    if (its only a number)
    {
    }
    else if (its only a float)
    {
    }
    else //its a string
    {
    }
}

pawn Код:

// ** INCLUDES

#include <a_samp>

// ** MAIN

main()
{
    print("Loaded \"argument_type.amx\".");

    Function(""); // "2" = integer, "2.0" = float, "test" = string
}

// ** CALLBACKS

public OnGameModeInit()
{
    return 1;
}

public OnGameModeExit()
{
    return 1;
}

// ** FUNCTIONS

stock Function({_, Float}:...)
{
    new string[144], bool:character = false, bool:point = false, bool:number = false;
    for(new i = 0, j = sizeof(string); i < j; i ++)
    {
        string[i] = getarg(0, i);
    }

    for(new i = 0, j = strlen(string); i < j; i ++)
    {
        if(!character)
        {
            switch(string[i])
            {
                case 'A'..'z':
                {
                    character = true;
                }   
            }
        }

        if(!point)
        {
            switch(string[i])
            {
                case '.':
                {
                    point = true;
                }
            }
        }

        if(!number)
        {
            switch(string[i])
            {
                case '0'..'9':
                {
                    number = true;
                }
            }
        }
    }

    if(character)
    {
        print("string");
    }
    else if(number && point)
    {
        print("float");
    }
    else
    {
        print("integer");
    }
    return 1;
}

Remember to put the arguments in double quotes.

tagof only works for elements with TAGS, integer and strings doesn't have one.

So how can we detect those 2?

That's what i don't want. I need to input any type and then detect internally. (idk if its possible in PAWN)

Try:

PHP код:

if(tagof(var) == tagof(_:))

Doesn't work for numbers without (_:) tag.

There is really no way to detect it you need to pass the format of argument like in functions like mysql_tquery, where you pass the format of variable to be passed to callback as a string.
tagof doesn't works with getarg directly it gives error.
For example:

PHP код:

tagof(getarg(0)); // gives error won't compile 


So best option is to make your function something like

PHP код:

//example call to function someFunction("dfd", 3, 45, 55.5, 8)
stock someFunction(args[],  s = sizeof(args), ...)
{
     for(new i = 0; i < s; i++)
     {
         switch(getarg(0, i))
         {
             case 'd':{ /* interger */ }
             case 'f':{ /* float */ }
             //so on
         }
     }
}
