Blast Resistance vs Pick Breakage

[AlanEsh]

Hey all, questions about these two characteristics of blocks.

- Generally, does high blast resistance mean it is harder to break with a pick, and vice versa?

- Is it typical that one mod (looking at you, Railcraft) gives the same blast resistance to similar blocks? For example, both the Stone Post and the Concrete Block require Stone and Rebar to craft. However the Concrete Block is -much- easier to break (equivalent to natural stone). In contrast, the Stone Post takes about half the whacks it would take to break Obsidian... pretty tough stuff to work with.

- Is there an up to date table somewhere that shows/compares the blast resistance values of building blocks in the FTB mods? If not, is this something I might find in the mod config files or something?

Thanks!

Blast resistance is how hard of a blast a block can take before breaking, as something with a blast resistance can withstand a creeper at point plank range, but cant take a chunk of TNT at point blank range (Just examples, dont quote me on any of this xD)

while not directly linked, something with a higher blast resistance will generally have a longer break time, prime example, obsidian

The railcraft stuff is best broken with a crowbar- right tool for the right job.

As a general rule of thumb- blast resistance is related to mining time.

There are exceptions- glass takes a bit longer to break than blast, and TF mazestone wreaks your tools but crumbles with explosives.

That would be a logical correlation, and a useful one to determine the rough blast resistance of materials without needing a wiki if it does, in fact, work that way. Here is a list of the vanilla blocks' blast resistance: http://www.minecraftwiki.net/wiki/Explosion#Blast_Resistance which I'd say would be a start for testing. Specifically, try and see if there is a mathematical link between mining time with a diamond unenchanted pickaxe versus their blast resistance. Ones that stick out to me are this:

• Stone and cobblestone are both listed at 30, whereas cobblestone takes a bit (perhaps 130$ of stone) longer to mine.
• Anvils and Enchantment tables are at 6,000, and mine much faster than obsidian.
• Dirt is 2.5, but it breaks roughly twice as fast as smooth stone.

I would conclude from these three data points that blast resistance is not related to breaking time directly. There may be an indirect relationship, but it is not something that is being set without someone specifying the different values most likely.

They're separate values. It's up to the implementation of each individual block to determine how these values relate to each other, if at all. An interesting example is rockwool: Same appearance, behavior, and mining time as wool, but has the blast resistance of stone (and is fireproof).

Neah, there's no correlation, except logical of course. I know this from my brushes with modding, the two are set separately. However it's usually only logical to make your blast resitant blocks also resistant to breaking, so that's why it's usually like that. Notch set the first example with obsidian and modders followed suite.

There are two independent numbers. Most mod blocks maintain the correlation set by vanilla, but it's not a problem to code a block that breaks in an instant, yet is explosion-proof (or vice versa). Above posts already mention a few examples. I'd add XY shields as extremely blast resistant (roughly reinforced stone level), but easy to break with a pick.

The best way to test blast resistance is to go into a test world and blow up a bunch of TNT/nukes encased in the tested block.

Hardened CF foam is supposedly blast resistant but it's like butter against a pick.

Sounds like I have an evening planned out for me, thanks guy
