Talk:TNT

Not sure mining with TNT is really abuse, I mean, its actually realistic, and gunpowder is a rarer to obtain than stone, and even iron. Assuming wood and sand are both readily available (which if replanting and not building large glass structures, they should be), and assuming you dig 2 blocks deep before planting the TNT to maximise it, you get 5 blocks removed per unit of black powder, while you get <22 per block of stone, which is the more available resource anyway ('scuse the redundancy, did the maths in my head anyway, and thought I'd record it.) You also will collect stone whilst mining out the hall to replace that used. --The Sero 16:18, 30 August 2010 (PDT)


 * TNT mining is kind of dumb to do, cause you blow up any ore thats in its way.Toadbert


 * The whole part about destroying the ore in the way is a big problem, but it could be useful for clearing large chunks of less valuable blocks (gravel, dirt, etc.) But yeah, not good for mining for things you actually want. -Lunar180 17:18, 27 September 2010 (PST)

Mining with TNT
I added a small section about mining with TNT, and which ores will and won't be destroyed. It needs more experimentation, though, so feel free to add to or correct it. After more tests I found that my earlier theory didn't hold up, as gold ore and iron ore can also occasionally be found in the debris. LTK 70 00:34, 19 October 2010 (UTC)

I've been doing more tests on the percentage of blocks destroyed by an explosion. I demolished a 3x3x3 block of iron ore with TNT in the middle ten times, and on average I got 32.3% blocks back, the highest being 14 and the lowest being 5 out of 26. I will see if this average also counts for other block types, but for now it seems that the destruction rate of blocks is about 1/3 on average. It would be most helpful if others experimented on this as well. LTK 70 17:19, 21 October 2010 (CDT)

Blocks' TNT resistance
Someone should try to get the strength of special blocks (fences, doors, etc.). I'm going to try to test the strength of furnaces and crafting tables. :D PurpleKiwi 06:45, 24 October 2010 (UTC)

I just tested the crafting table, furnace, wooden door, and sapling. I can't really test out saplings since it can only be put on soil (and breaks if the soil breaks). PurpleKiwi 07:32, 24 October 2010 (UTC)

Risugami, a modder, has made a chart of the real resistance values used in the game's code, and give a small explanation of how they're used. What we need now, is to know what the 'damage' value of TNT is, in regards to this temporary health, and Creepers too, since their explosions are weaker, and how the damage dissipates with distance. Also, blowing up obsidian with TNT is fun. CyborgDragon 20:50, 24 October 2010 (CDT)
 * How much TNT do you need to destroy Obsidian? PurpleKiwi 22:56, 24 October 2010 (CDT)
 * Not sure of the exact amount, I placed a hollow 3x3 tower, up to ground level, of TNT on top of the obsidian, then used redstone to activate as much as possible at once. Sure enough about 4 blocks of obsidian were vaporized. CyborgDragon 07:26, 25 October 2010 (CDT)
 * The damage of TNT is at least 37.5 (it goes through a bookshelf and then destroys a block of stone), with an upper bound (assuming that damage doesn't fall off because of distance) of 42.5 (it goes through a chest, but then can't break the stone behind it). As damage does seem to fall off over distance, that upper bound is invalid, but if we can figure out how damage falls off with distance, we could use that to obtain a better figure.

 * I wonder how you'd test Creeper explosions... Imagining it makes me laugh. Creepers can't destroy furnaces. A creeper destroyed the top part of my underground mini-base, but it couldn't penetrate the furnace-lined basement. Now I use furnaces as building material.PurpleKiwi! 03:41, 30 October 2010 (UTC)

Is this really a bug?
I think that the fact that you can use the TNT to make an arrow cannon may be intentional, should this be moved to a trivia section? Oa10712 18:24, 30 October 2010 (UTC)
