Instant Mining on Custom Blocks

xhelly

Hi! I'm making a prison server and i add some custom blocks to the mines, the thing is, when a player have like a ef. 20 pickaxe, the custom blocks are not affected with instant minning, any way to fix this?
Other thing, not urgent, some blocks somethimes their texture bug for like 1-2sec, idk if its possible to fix that too.

Thank you!

I am looking for an answer to the question about the flickering of the blocks myself. There is also a problem with the axe- even if the blocks are metal, for example, and the axe is strong enough to quickly break the note block, then the first two or three break_stage will be skipped and the animation of the breakdown will go from the middle

By the way, I noticed that the blocks lose their texture when interacting with water, lava, redstone and sand. It is also impossible to move them with a piston
