hey there! is it possible to make plugin which lets you turn certain blocks into fake blocks? fake blocks = blocks on which the player cant stand on so you fall through
I don't think you can make 'false' blocks... You could make a block that disappears for a moment when it's stepped on, or something to that effect. You could rig that up with redstone + craftbook's bridges to some interesting ends. Oh! You could rig up a sand floor that floats until it's stepped on (and then falls normally) then remove the sand and put it back up. A tad complex, but it would be very cool to see in action.
