Java Edition 1.3.1/List of broken features

This page details features which were broken by 12w18a's client-server logic split.

Expanding Ghasts
When Ghasts were first added, they would expand slightly before shooting a fireball, similarly to a creeper about to explode. This created the effect of the ghast "charging" a fireball, rather than just opening its mouth and firing it. However, the effect was not properly networked from the server to the client, causing it to not work in multiplayer. As a result, when singleplayer was changed to use an internal server in 1.3.1, the effect broke there too. The expand code was removed entirely in 1.8.



Directional damage tilt
Originally, taking damage would cause the camera to tilt towards the direction the damage came from. However, the direction value was not properly networked from the server to the client, causing the camera to always tilt left in multiplayer. As a result, when singleplayer was changed to use an internal server in 1.3.1, the directional tilt broke there too. This was reported on the issue tracker and very controversially marked as "Won't Fix", though the (broken) code remains in the game to this day.





Progress bars
When generating or loading a world or entering a given dimension, a green progress bar would appear on screen under relevant text. This no longer appears. For world generation and loading this was effectively replaced with a chunk graph, but dimension loading screens still show nothing.

Entering dimension text
When entering the Nether or End, the screen would respectively display "Entering the Nether" or "Entering the End". Leaving either dimension would display "Leaving the Nether" or "Leaving the End". This no longer occurs.

Saving Level text
In the pause menu, the bottom left would display "Saving level..." for a few seconds as it saved the level. This no longer displays, despite entering the pause menu still saving the game like before.

Minecart physics
Prior to the client-server split, minecraft's were capable of pushing players, and would react immediately and change direction when pushed. However, minecarts no longer push the player, and turn very sluggishly.
