It would be fantastic if guests could have a trigger. So if they for example comes to a door you can have it triggered to open..
this would kill your game, imagine having 1000 doors actively open and closing for every 10,000 guest in your park. That is 20,000,000 active animations Open and Close.
To many active Animations are one of the top things that kill a game. This is more prominent on low end PCs and conceals.
For this to really work in a open world sandbox game. A bunch of constraints would need to be implemented.
FOV - Field Of View, if you cant directly see it then it shouldn't animate.
FOV 2 - If the player camera is a specific area distance away from the object then it does not animate.
Limit of active objects in the world space. this has to be a hard cap for overall performance.
All these settings adjustable in a menu. This way you can control Fun over Looks
- Of Corse this an extreme example but some one will try it at some point. - As its been a on going computation to brake the game with decoration - Rather then just have fun
