So my goal is to create a medium sized city with tall buildings. The player will be able to go inside some of the buildings and go up the staircase to each floor. Or take the elevator if it's working.
Also each floor will have minimal miscellaneous furniture and cabinets.
Each interior floor will have enemies like zombies for example spawned dynamically.
My plan to make this run at a smooth fps.
LODs on outside building structure.
Spawn the interior floor only when player enters through them. (Like Skyrim doors which black out the screen and then the interior is loaded)
Add furnitures and objects to a floor and save it in the database to load it dynamically.
If a building is 10 floors. Add the upper floor dynamically when player goes up the staircase and delete below level.
Save and Load enemies depending on the player position.
The jitter test: after starting the game, wave your hands in front of your face. If they jitter, still needs load shedding and optimization.
Still there are outside elements like roads, broken cars. I was wondering if it is actually possible to pull this off?
I was looking for a city free roam. How would you approach this?
