Modding Discussion • Re: Temperature system for a winter survival game.

This is certainly doable to some degree (no pun intended). My game server makes extensive use of weather and temperature based survival, including a "Temp Felt" HUD and even a vignette overlay to give a visceral indication of temperature extremes.

Players must still be selective when venturing out in the cold (to avoid frostbite) or when mining in lava caves (so as not to get heatstroke) by wearing armor with suitable insulation and conduction properties. Similarly wielding a torch will give a warming sensation while holding an ice cube will result in a cooling effect.

While the game mechanic on my server isn't quite as elaborate as you described (i.e. heat being confined to a specific room) it nevertheless does account for radiation sources. That is, a node can propogate heat radially or on contact, or even both (such as a furnace which will burn you when touched, but provide moderate warmth from a distance). This is accomplished by use of my Axon framework:

Of course, in my case I'm focused on optimizing for server performance (network, CPU, etc.) rather than ultra-realism. But since your game is most likely intended for single-player on a local machine, you probably won't have those same constraints. I would be interested in seeing what direction you plan to take with your project!
