I have been looking for a plugin that allows you to have a wall and then 2 blocks that appear as wall but you can walk through it. 22222 22122 22122 the 2's being wall you cant walk through and the 1's being wall that you can walk through
i dont think variabletriggers will allow the wall to stay visible but be able to walk through it though. however if anyone has tried and finds this to work let me know.
And I don't think Bukkit will allow the wall to stay visible but be able to walk through. That's called NoClip, you'll need a client mod.
An easy way around that is to turn the blocks into air the moment a player is touching the "door". Then the blocks can be turned back when the player is through the wall. But I'm pretty sure this can also be accomplished with piston doors and player detectors, though. A plugin might be overkill.
