Lagback

Lagback refers to getting teleported back to a previous position. The causes for lagbacking are various, but most are probably not intended, for example:


 * Colliding with a boat
 * Falling (while sneaking)
 * Moving inside a cactus too quickly

Lagback can be abused to clip inside walls, or jump higher in a similar fashion as Blips. This practice may be a bannable offense on multiplayer servers. In this article, we solely focus on singleplayer 1.8.

Explanation
The lagback itself is caused by this portion of code (in class NetHandlerPlayServer): The reason why this portion of code activates is different for each of the aforementioned inhibitors.
