where to go now?

[bocochoco]

Makes a little @ run around the screen... I honestly am not sure how to continue at this point. Whats the next best logical step?

Code: [Select]

#include <stdio.h>
#include <curses.h>
#include <string.h>

using namespace std;

int main()
{
    int rows, cols;
    char msg[] = "Press wasd to move around. Shift+E to exit";

    int px = 15;
    int py = 15;
    bool running = true;

    initscr(); // Begin Curses
    curs_set(0);
    getmaxyx(stdscr, rows, cols);

    init_pair(1, COLOR_GREEN, COLOR_BLACK);
    init_pair(2, COLOR_CYAN, COLOR_BLACK);
    init_pair(3, COLOR_MAGENTA, COLOR_BLACK);

    attron(COLOR_PAIR(2));
    mvprintw(rows / 2, (cols / 2) - (strlen(msg) / 2), "%s", msg);\
    attroff(COLOR_PAIR(2));

    while(running)
    {
        int ch;
        ch = getch();

        switch(ch)
        {
            case 0x77:              // w key
                if(px > 0)
                    px -= 1;
                break;
            case 0x73:              // s key
                if(px < rows - 1)
                    px += 1;
                break;
            case 0x61:              // a key
                if(py > 0)
                    py -= 1;
                break;
            case 0x64:              // d key
                if(py < cols - 1)
                    py += 1;
                break;
            case 0x57:              // W key
                px = 0;
                break;
            case 0x53:              // S key
                px = rows - 1;
                break;
            case 0x41:              // A key
                py = 0;
                break;
            case 0x44:              // D key
                py = cols - 1;
                break;
            case 0x45:              // E key
                running = false;
                break;

        }
        clear();
        attron(COLOR_PAIR(1));
        mvprintw(px, py, "@");
        attroff(COLOR_PAIR(1));

        refresh();
    }

    endwin(); // End Curses
    return 0;
}

I'd go with a map. either hardcoded for starters, or generated.
Next step Items
Then Monsters
Then you have a finished roguelike

[freeofme]

This is actualy a pretty good basic guide.

[Ex]

Definitely a map next. Use an array, loop over it for display like: for(i=0;i<80;i++)for(j=0;j<25;j++)Map[ i][j]; Then monsters, etc..

You included string.h but you use c-style strings. You do need c-style strings for the curses functions, but you can use c_str() to convert c++ strings to c-style strings.

Code: [Select]

string msg = "Press wasd to move around. Shift+E to exit";

mvaddstr(rows / 2, (cols / 2) - (msg.length()/ 2),msg.c_str());
That should work.

I tried that before, gave me a lot of errors. Replaced #include <string.h> with nothing, errors for missing string header. #include <string> however exploded:

I'm still quite new to c++, since I haven't used it in over a year. Figured it would be a good way to learn it again to do something that I enjoy in it. Are there any code examples for how to implement a map? Or little helpful tidbits of information? The thing that I know I'm going to have the most difficulty with is making a map that is bigger than the console window centering on the player.

Thanks ^_^

You included string.h but you use c-style strings. You do need c-style strings for the curses functions, but you can use c_str() to convert c++ strings to c-style strings.

What's the problem? <string.h> is a string library for C, he uses C-style strings in his program and Curses use C-style strings. It's alright.

Of course C++ strings from <string> are much better (especially for newbies, as C strings are very low level).

I tried that before, gave me a lot of errors. Replaced #include <string.h> with nothing, errors for missing string header. #include <string> however exploded:

I think you should #include <string> before curses (i.e., the order of inclusion matters here). You also have to add "include namespace std;".

What's the problem?

I don't know as much as I thought I did. That is the problem. Sorry....
