Point and click engine?
The engine itself is pretty straightforward and requires some basic things:
-Defining a walkable area
-Defining objects and their properties, such as obtainable, triggers, map links, etc.
-Really simple pathfinding
-An inventory (if it has that kind of thing)
-Dialog boxes (I can't think of a point and click game that doesn't have dialog)
-Room transitions (not so hard)
And then if you want to get more complex, you can do stuff like making a way to define a mapping for combining items, timed events, etc. Even though the engine is probably simple, a LOT of time would have to be sunk into designing the environment, setting up all the puzzles and items, and writing all the dialog. Some games are difficult in a technical aspect, but in this case the difficulty comes from the "artistic" side.
Uhhh but that's not the answer you wanted lol. No, I don't think anybody has made an "engine" for that yet.
@randomouscrap that was a very informative answer though. Thanks for that. Maybe I will start some very simple stuff for a point and click engine. I've had a lot of trouble understanding SmileBasic. But I will start on some of the easier stuff for a point and click type of game engine tonight. Would love to see some point and click type of stuff come out. I loved a game on the Wii-U called Lone Survivor. Graphically not all that great but storyline absolutely top notch
