Problems on strings of an enumerator of a 2D array - leong124 - 17.05.2011

I recently find a new problem on 2D array again.

pawn Код:

enum test
{
    test1,
    test2[128]
}

public OnFilterScriptInit()
{
    new testarr[test] =
    {
        1,"hello world!"
    };
    print(testarr[test2]);
    testarr[test2][0] = '\0';
    format(testarr[test2],sizeof(testarr[test2]),"helloworld!!");
    print(testarr[test2]);
    return 1;
}

Works fine and you can change the values of testarr[test2],
but when the testarr goes 2D,

pawn Код:

[enum test
{
    test1,
    test2[128]
}

public OnFilterScriptInit()
{
    new testarr[1][test] =
    {
        {1,"hello world!"}
    };
    print(testarr[0][test2]);
    testarr[0][test2][0] = '\0';
    format(testarr[0][test2],sizeof(testarr[0][test2]),"helloworld!!");//Line 31
    print(testarr[0][test2]);
    return 1;
}

Gives out compiler errors:

4 Errors.

All errors occurs on that format(trying to change the value of that string).
Single cell access seems to be working but you can't change the whole string.

Weird..

I think it's because PAWN only supports 2 dimensional arrays and when you have a string, inside an enumeration, inside a 2D array, it kinda acts as a 3D array so pawno freaks out.

Pawn supports arrays up to 3 dimensions ...

I have always had this issue, just use strcat or strmid on it.

Re: Problems on strings of an enumerator of a 2D array - leong124 - 17.05.2011

I find the only problem is that sizeof for strings in enumator types will not work,
causing strcat/format,etc. don't work(since they need the size of the string).
If you specify their size, for example 128, it will work.

And yeah, PAWN starts to fail when there's multi-dimensional arrays(even 2D array).
I've found this problem long time ago:

pawn Код:

new i;
switch(i)
{
    case 0:
    {
        new string[2][128];
        string[0][0] = '\0';
    }
    default:
    {
        new string[2][128];
        string[0][0] = '\0';
    }
}

Try to compile it

Edit:
This thread is posted long time ago, but I still have to say that I found the solution. That's a fault of not understanding the actual format:

pawn Код:

format(testarr[0][test2],sizeof(testarr[][]),"helloworld!!");

It should work, but still, the switch problem above is indeed a bug.
