Seriously I have no idea how to hide anything (such as a block) from one user but show it for another (I'm trying to give staff secret menus so they can pass files to each other, make them hidden etc). This tutorial ( is great for 1.9 but I'm maybe using version (actually there doesn't even from my research too be able to find what version I'm using) 2.4 and I'm having some difficulty. I've been trying to hide a block from a teacher but to no avail. Please help - this is something really simple and yet so important. Thanks.
