As I continue to play with Lua on Gens my thoughts have turned towards the potential to make a real time level editor using it.
I wondered if anyone has attempted it before or if there are any examples already out there? (Search turned up some interesting post but nothing related.)
It doesn't have to be a level editor, a stat editor or similar would be good to see.
The important part here is I'm not just looking for something that can poke memory here and there as that is fairly straightforward. What I've got in mind is essentially you walk around the world as you normally would and there is an overlay that let's you change the values being used for the map. You tweak the values and the map updates real time, once done you hit save on the overlay and it writes out your map to a separate file, ready for you to import into the ROM.
Obviously that's pretty high level, editing memory real time may well crash the game, the output you get may not be able to insert directly back into the ROM as is and a slew of other issues but as a concept what do you think? And has it been done before?
