Hi toon_mad,

I'm not sure there are ready made editors as I've always written one that is specifically for the engine I was working on at the time. Typically, I think most people will do this... develop the engine and the editor in parallel so that the editor fits the engine perfectly. I don't have any example code unfortunately, but there are a number of tutorials available online about how to do this sort of thing in relation to platform games.


Regards
