Steps to Reproduce:
To reproduce the bug, have a mob with a directional attack, like a skeleton or a zombie, attack you from different sides. Notice the direction the screen tilts from damage.

Expected Results:
The expected behaviour is that the screen tilts away from the direction of the damage. This behaviour can be observed in v1.2.0 Alpha.

Observed Results:
The screen always tilts towards left.

Context:
Since version v1.2.0 of Java Edition Alpha, damage titlt would correspond to the direction of the damage. This meant if an arrow hit you from the left, it would tilt right. This didn't work properly in multiplayer. After the change that made all worlds technically servers, it also has stopped working in singleplayer.
