i see you just joined the DB forum

basic is a language.... you must make everything ....
most people assume that a level is a game,
a game actually plays levels...
Unless you wrote a game, you can't play a level...
its a catch 22....
start on paper
figure out how you will represent a level in code....
see the huge dungeon demo as an example.
It uses notepad as a level editor and shows how to
write code to load that level...
There are tools that help simplify things, but you should know
how they work BEFORE you try using them. Magic World is cool, but can't do everything for you. You will need to modify it for your purpose. But, in order to modify it, you must understand how it works. How it reads data from a binary file and converts that into a 3D matrix object. I use it to load infinit matrix objects instead of the default size matrix. Also I use it for DBPro instead of DBC. Its a great app and saves me the time required to build it myself.
