How to make one playable frame that loads layouts?

[wowgus]

I'm wondering how I can make one frame that actually plays the game, but loads level layouts, so that I would only have to make changes once instead of multiple times.

Thanks in advance.

First you will have to code a leveleditor with a save and load routine. You can store the leveldata in a ini or array file. You must then load the content of the file in the gameframe.
There are many ways of going about this. It can actually be very simple and really fast to do. But before you start out, learn about ForEach loops, Fastloops and ini / arrays if you haven't allready, because that knowledge will be essential.

Popcorn is correct but you dont need to build your level editor to be a seperate application anymore.
AndyH did a fantastic example of saving and loading levels with MMF own editor
