In Minecraft 1.4_01 if I have a vertical wall standing on dirt with a water source block placed where the wall and ground meet (see below) can spiders (or any mob for that matter) even reach the wall?

C = Cobblestone
D = Dirt
W = Water Source


For the sake of simplicity I've intentionally not listed flowing water.

At the moment, mobs cannot move fast enough to fight a current. However, this is rumored to change in a later patch.

    Or the source of your information if you haven't personally tested this?

  • It's just from personal testing, this isn't really a hard one to prove. As for the rumors, I only remember hearing them.

  • My initial hidey hole had a river flowing out of half of it, and nothing has ever made it in.
