ASCII dungeon template

[lilhawk2892]

im currently designing my rpg engine.. just to see what i can do. im currently at the point where i would like to implement a visual dungeon. im thinking of making a text file with the design

text file::

|===============|
|               |
|               |
|               |
|               |
|               |
|===============|

int the DrawMap function it looks for the folder where the text files are located and picks the most logical map ie map1a map2b

everyline in the text file is converted to an array and represented on the screen. i have this much working. mostly. but movement is a problem. a serious problem. im having troubles figuring out how to make it so the user cannot move out of boundarys or an event occurs etc etc. can anyone help with this problem

Maybe add some dots to mark the floors / passageways?

So, I presume when you load the map for a particular room/area, you do so into a 2D character array?

If so, the movement should be restricted to the parts of [or inside of] the map that is spaces delimited by your | and = signs (walls). The player obviously has a starting point within the room, and can then move within the room by [for example] keypresses. If the movement "hits a wall", then it's not a valid move.

What part of this procedure is it that you can't achieve?

Hi Lil!

You can store an entire area where the user is in a matrix, then store user position and when he moves check inside the matrix if the destination square is valid.
This way you can control any kind of event, not only collisions against walls

Heres some pseudo code of how you could check for collisions:

void Input()
{
    if(KEY_HIT_RIGHT)
        if(!Collision(player_x+1, player_y))
            player_x++;
    if(KEY_HIT_LEFT)
        if(!Collision(player_x-1, player_y))
           player_x--;
    if(KEY_HIT_DOWN)
        if(!Collission(player_x, player_y+1))
           player_y--;
    if(KEY_HIT_UP)
        if(!Collission(player_x, player_y-1))
           player_y--;
}

bool Collsion(x, y)
{
    if(x < 0 || x>= MAP_WIDTH)
        return true;
    if(y < 0 || y>= MAP_HEIGHT)
        return true; 

    if(map[x][y] == '=') 
        return true;
    if(map[x][y] == '|')
        retrun true;

    return false;
}

bool Collsion(x, y)
[/code]

which is it, collisions or collsions?

Well I said it was pseudo code, so I should be allowed to make typos ;D

Of course you are: I just spotted another typo:

    if(KEY_HIT_DOWN)
        if(!Collission(player_x, player_y+1))
           player_y--;
