Unbreakable blocks in adventure mode: Hay Block, TNT, Silverfish, Piston, Cactus, Bed, Fire, Sponge

By the looks of it, silverfish blocks don't have a specific tool set for mining them out.

I thought adventure mode ment you cant place or break blocks, and that resources had to be collected by creepers. Does this mean that instead you can mine stone materials with picks, wood with axes, and dirt materials with shovels?

Michael, Adventure mode has recently changed from "you can't destroy blocks" to "you can destroy blocks with the right tool". You can chop down trees, so long as you have an axe of some kind, you can mine as long as you have a pick, but if you lose your tools you are stuck.
Silverfish blocks disguise as normal stone blocks, so in adventure mode they should ideally be breakable by the same tools that stone is breakable by (i.e. a pickaxe)

I think that you can break it in 1.4.5 since a lot of blocks are breakable without any tools in adventure mode. But that's another bug

Silverfish blocks are still unbreakable in adventure mode as of 13w02b. Recommend maybe making silverfish mine-able via a pick?

Add sponges to the list too. As long as adventure mode is going to be breaking blocks only with the right tools, then everything should be breakable with some tool for it to be a fully usable game mode. There should be a no-build/break mode too, but that's another issue.

Also, stone half-slabs and double-slabs can be targeted with an axe, which seems incorrect. And axes should probably be able to target leaves and melons, but currently they do not.

I would propose the following changes:

TNT: either shears or anything
Monster Egg: Pickaxe
Pistons: Pickaxe or anything
Cactus: Axe
Bed: Axe
Fire: Anything
Sponge: Anything
Cake: Anything

Is this still a concern in the current Minecraft version 1.6.4 / Launcher version 1.2.5 ? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

This is still on Minecraft 1.7.2!
Please Mojang, change the blocks to make them breakable. You can't play in Adventure mode, when you want to store your haybales in the shed and couldn't pick them up again, when you need them to "feed" your cows 😞
I would prefer to use the shears for breaking the haybales and the other suggestions of "B R" 🙂
Could introduce it in 1.7.3 😉

I agree for all of these things, for somes I don't know how it could be done but this is my propositions :
Silverfish : Pickaxe, since they are basically stone.
Piston : Pickaxe , since they are made by 6/9 Pickaxe based items and only 3/9 Axe based items
Bed : Axe since it's made of wood and wool, and in reality when you unmount a bed, the major part you unmount is the bed frame, not the mattress.
Fire : nothing, using a water bucket like you should in reality ... and it seems to already working (so the nether would be harder).
Sponge : Don't know, don't generate naturaly.
TNT : Any tool
Cactus : Anything or sword, like vines, crops, pumpkins or melons.

1.8 adventure mode changes should close this issue too.
