I've finally achieved my goal for this logic system I was working on.

All the interactivity in the above gif (the toggle doors, the colour changing, the popup) is powered by this amount of logic code which i write in the editor and is saved directly into the level!

Although not the nicest thing to work with in terms of readability, it drastically reduces the amount of work i have to do per "world" as i can write all its custom behavioural stuff into the level and not clutter the project with scripts.
