This is something I have been working on for a little while, it creates a grid which is represents by square units, the player can use arrow keys to move around. Currently I have random battles, stairs that go up and down, and exiting the dungeon.
The best part about this is it takes up little space on the map. When players move up or down a level it removes the dungeon and replaces it with the new level. That and the files that i have imported take up little space because they are using textures already in the game.
Only single player is supported right now, and unfortunately the only way to make it multi-player is to do alot of copy and paste. This takes alot of variables.
[edit]i updated a little, you can find the newer version lower in the thread. |
