I've been implementing Bukkit plugin for creating toggleable in-game warping areas that will teleport any catched entity to other similar area.
I was going to implement concept of non-Euclidean maze using this plugin, but, unfortunately, I've discovered that doing
Entity.teleport() causes client to interpolate movement while teleporting, so player slides towards target like Enderman and receives screen updates, so for a split second all underground stuff is visible.
While for "just teleport me where I want" usage this is just fine, it ruins whole idea of seamless teleporting, as player can clearly see when transfer happened even without need to look at debug screen.
Is there possibility to somehow disable interpolating while teleporting without modifying client, or maybe prevent client from updating screen while it's being teleported?
