Thread: an array in an array...

Not sure if I understand you correctly, but maybe you could add an extra dimension into your array. So instead it would look like this: map[map #][x pos][y pos]

int MAPFUNCTION(char Pmap[20][40],int sx,int sy,int drct);

I would make that prototype be
int MAPFUNCTION(char *,int sx,int sy,int drct);

Is that what you already tried? If so that should work fine as far as I know

I think you are missing a pair of brackets, put another one at the beginning and one at the end.

No, you'll need int MAPFUNCTION(char **,int sx,int sy,int drct);
That, being the exact same as
int MAPFUNCTION(char Pmap[20][40],int sx,int sy,int drct)
as one address is still pushed onto the stack

I have made several "maps" and would like an easy way to call all of them into a function.

the maps look similiar to:
char map1[2][4]={{g,g,g,g},
{g,w,w,g}};

now to call it into a function i merely did...

Code:

int MAPFUNCTION(char Pmap[20][40],int sx,int sy,int drct)
{
for(x=0;x<20;x++)
	{
		for(int y=0;y<40; y++)
		{
			PMap[x][y];
			if(PMap[x][y]==g)
			{fgreen;}
			if(PMap[x][y]==c)
			{
				charX=x;
				charY=y;
				fiblue;
			}
			if(PMap[x][y]==w)
			{grey;}
			if(PMap[x][y]==r)
			{fblue;}
			if(PMap[x][y]==d)
			{brown;}
			cout<<PMap[x][y];
		}
		cout<<endl;
	}
}

so that all works good and fine...until a character walks off the edge of the map...

i need someway to call in the next map...which i could do if I could put each of the maps into an array...or something similiar...just wondering what i could do...

BTW:i cut alot out of my code...so its small enough to glance over...

Instead of putting a third dimension onto your list, why not put your data into a structure or class and create a linked list? Instead of a single link, you could have four... one for each direction. Then you could easily and efficiently decide what map to load based on situations that arise.

It may be a little over your head, (I have no idea what your coding abilities are though) but I think it would be a much better design.

sweet I actually learned something useful just now! Eibro is my hero! *bows before Eibro*

hey Eibro aren't you dual catfish? (dual catfish++)

Yep, that's me!

ah im learning about linked lists right now...getting a little confused...tutorials dont always make things so simple to newbit programmers ;P

but ill look into doing it that way.

It may not be easy, but you'll learn a lot more doing it that way than you will doing it a way which you're already familiar with.
