3D Arrays

[URSvAir]

Hi all,

I'm trying to make a RPG game inside a console application and so far it's going great with events and programmable text boxes. But to add more rooms and maps I need a 3d array. So I could type something like this:

char Map1[10][20] = {}; // Map 1 goes here

char Map2[10][20] = {}; // Map 2 goes here

char Maps[10][20][50] // Same as before but made to hold 50 maps
for(int y = 0; y < 10; y ++){ // Make a 20 x 10 grid in computers mind
for(int x = 0; x < 20; x ++){
Maps[y][x][0] = Map1[y][x]; // save that tile from the drawn map to char maps
Maps[y][x][1] = Map2[y][x];
}
}

Once again, if I can get this to work it will save me 200 lines of code for each map I want to use. The error my compiler throws out at me when I do this is:

Error: Invalid conversion from char(*) 20 to char[20]

Can anybody help me with this, and if you can't can you give me some suggestions on what else I could try.

Thanks all.

EDIT 1 --- I've already screwed my whole code over anyway so I may as well start again if nobody can help in any way.

Which line gives you that?
Any way, memcpy, or use vectors instead of arrays.

Or you could avoid all the copying by making Maps an array of pointers. I honestly have no clue about how to write a pointer to a 2d array, so I would suggest to wrap that 2d in a struct:

struct Map{
   char data[20][10];//this might as well be data[200]. It doesn't make much difference.
   char& get( int x, int y);
}

You can then still do the = {} initialization, but you can't do [][] access, so I added a getter.
Maps would then be

Map* maps[50] =
   {&map1, &map2};

Or you could (should) store all the maps in a file and read only the one you need thus not having a 3d array at all.

The thing is, I haven't got that far for any of the crap you just mentioned. I've barely been reading through my book. I just need a way to make a 3d array and put the maps into it.

Once I get to saving and editing files in my book I will try to make a map editor and a way for the engine to read those maps and put them into the array.

Ok. But still, which line does the error come from? I don't see anything wrong in the snippet you posted (except for a missing ; on line 5).
