Currently I am working on a quick game for some friends, but I don't know the proper name for this type of game, so here is an example of the mechanic in The Lion King II:
To unlock the exit, you need to cover the ground with paw prints and not get caught by enemies.
I am trying to recreate the footprint-path covering part but I don't know if this has a proper name/term or not and can't find any tutorials to get started.
Currently I have created several planes with the footprint texture going in either direction, and my plan is that when the player walks on it, depending on the direction, will make the appropriate texture appear, then something will check when the path is entirely covered, before setting the exit door to inactive.
