text-map

[Sinzygy]

Alright!

Here's what I'm trying to do:

Code: [Select]

  _____         _____         _____
 /     \       /     \       /     \
/ (0/0) \_____/ (2/0) \_____/ (4/0) \
\       /     \       /     \       /
 \_____/ (1/1) \_____/ (3/1) \_____/
 /     \       /     \       /     \
/ (0/2) \_____/ (2/2) \_____/ (4/2) \
\       /     \       /     \       /
 \_____/ (1/1) \_____/ (3/3) \_____/
 /     \       /     \       /     \
/ (0/4) \_____/ (2/5) \_____/ (4/4) \
\       /     \       /     \       /
 \_____/ (5/1) \_____/ (3/5) \_____/
 /     \       /     \       /     \
/ (0/6) \_____/ (2/6) \_____/ (4/6) \
\       /     \       /     \       /
 \_____/       \_____/       \_____/

I want to create it on the run and being able to zoom around.
But small steps: What would be a good way to do this?

my thought are using this sequence and just stack it on top of each other:

Code: [Select]

/     \       /     \       /     \
/ (0/0) \_____/ (2/0) \_____/ (4/0) \
\       /     \       /     \       /
 \_____/ (1/1) \_____/ (3/1) \_____/

but how would I go about that the most efficient? Plus adding the coordinates?

What kind of game is this map for?

[Sinzygy]

it's for a round-based strategy game.

[Ki Adi Mundi]

Kind of like the Civilization franchise games?  If so, I'd be interested in playing once it's ready.

[Sinzygy]

Haha, it will be a long time before this one is ready to be played. I still need to figure out a lot...

And it might be similar to Civ, but it's actually intended to serve as a port from the old pbem games to pbbgs.

What I would do is write a function called draw_hexagon, and it would just draw individual hexagons. One of the arguments would be scale_factor, so you could scale the map according to zoom distance. To draw a map, just call draw_hexagon repeatedly until the map is filled. It wouldn't be hard to come up with an algorithm to place the hexagons based on size, scale, position, etc.

Edit: oops, didn't realize you were actually doing it with text, I thought it was a diagram

[Zeggy]

I think one of the main problems is getting all the hexagons to tile with each other properly...

This is a great writeup on hexagonal maps in games.

As far as drawing, you could draw the text line by line, and just use repeating patterns. I'll go write a quick script now and get back to you.

Code: [Select]

<pre>

<?php
define('HEX_ROWS', 10);
define('HEX_COLS', 10);

echo str_repeat(str_repeat("&nbsp;", 2) . str_repeat("_", 5) . str_repeat("&nbsp;", 7), HEX_COLS / 2);
echo "<br />";

for ($row = 0; $row < HEX_ROWS; $row++)
{
 for ($line = 0; $line < 4; $line++)
 {
  switch ($line)
  {
   case 0:
    echo str_repeat("&nbsp;/" . str_repeat("&nbsp;", 5) . "\\" . str_repeat("&nbsp;", 6), HEX_COLS / 2);
    echo "<br />";
    break;

   case 1:
    for ($col = 0; $col < HEX_COLS; $col+=2)
    {
     echo "/&nbsp;(" . $col . "/" . $row . ")&nbsp;\\_____";
    }
    echo "<br />";
    break;

   case 2:
    echo str_repeat("\\" . str_repeat("&nbsp;", 7) . "/" . str_repeat("&nbsp;", 5), HEX_COLS / 2);
    echo "<br />";
    break;

   case 3:
    for ($col = 1; $col < HEX_COLS; $col+=2)
    {
     echo "&nbsp;\\_____/&nbsp;(" . $col . "/" . $row . ")";
    }
    echo "<br />";
    break;
  }
 }
}
?>

</pre>

This is the basic idea. It still leaves the end tiles unfinished, but you shouldn't have a problem fixing that up, I just wanted to get you started. Good luck

[Sinzygy]

thanks for the link. I'll look into it as soon as I have enough spare time.

Woha, thanks a lot for this nice piece of code!
