Haha.
No wood to burn, and too much water to drink.
Infdev still needs some work I see
Well, I don't really need wood to burn stuff. Stuff doesn't tick like Someguyo said, so fires set with the flint and tinder never go out unless you snuff 'em. ...You can set invisible ones, too, apparently, if you aim at like a stone wall or something.
In that map with the floating foliage, I dug a little hall into the rock by the water, which went a bit in, split, and sorta made a mesa-platform sorta thing by going further back and rejoining.
I but a flame wall up by the entrance and shot all my arrows out to a nearby island, but eventually a skeleton shot me and his arrows were spawning crap past the wall. :\
Ran back to the split and barricaded the place, then layed like 40 TNTs.
There I learned that TNT has a large blast radius. At the furthest my thing reached I still took like my entire bar of health in damage. I lived, but my halls were now a hole, and I probably died jumping down from my little platform.
So I started experimenting with TNT. I dug a long trench and filled it with TNT, which got me a crater. I also tried digging around and spacing the TNT out haphazardly, which ened with me accidentally mining a box of TNT I'd already placed, at the furthest point in in my little TNT mine. That got me a larger crater-cavern, and left me with like 12-ish or so. Also, when night set during that one, I went and set a ring of fires around the site and put a bunch of TNT on the surface.
After that I made a bomb-house, the roof of which I set on fire. Then I discovered bomb-houses have REALLY big killzones.
