Unfortunately, the torches-on-one-side method tends to break down inside gigantic swiss-cheese caves, or in abandoned mineshafts, which are the places you’re most likely to get lost. :smack: My strategy is to use redstone torches to mark the pathway out – usually placed next to a regular torch, with the redstone torch on the side pointing towards the exit.
I’ll also mark dead-end passageways with a line of three torches on the floor, which creates a nice visual indication of the side passage being “blocked” and leading nowhere.
Crafting a compass (4 iron + 1 redstone) will always point towards your original spawn, though it will NOT change if you reset your spawn point by sleeping in a bed. Compasses don’t work in the Nether or The End, though.
If you’re trapped underwater, you can refill your breath meter by placing a torch on a wall next to you at head-height. The water will break the torch of course, but not before creating an air pocket which lasts a split second, long enough to refill your breath meter to max. Digging up into water isn’t all that dangerous, though, unless you’re stuck under ice. :eek:
