DJazz asked me if I had any ideas about making MCEs easier to put together, so here goes:

By know, you already know how the generating event's ID affects the created object's placement:



Using event 32 (in this case, Lori Start, thanks to JJ2+) will thus move the object 32 pixels to the right from its origin:



Now, imagine that you're me and you want to make a slightly complex bunch of MCEs like this:



My suggestion is: make the editor put a marker showing where the object will appear in game.



This would be useful to have, considering how it took me like 10 minutes to get this particular example MCE to appear correctly.
