setfuel command

Sets the fuel in every fueled light source around you (torches, braziers, fires) to the given amount. Saves a pile of resin and wood when dressing a base for screenshots or keeping a build lit during testing. Needs devcommands plus admin on a server.

Cheat commands need the console enabled with the -console launch option, then devcommands typed once. They work in singleplayer or when you host, not on dedicated servers.
