Procedural animated texture generation/Gears

This page describes content that has been removed and was only present in earlier versions of Java Edition.

 

Gears were removed in Java Edition Alpha v1.0.1.

Code which generates the frames of the gear texture can be found here.

The animation for gears was generated using two predefined image files - misc/gear.png for the rotating gear and misc/gearmiddle.png for the stationary center.

The animation is rendered as a 16×16 texture like most other blocks, with gear.png being downsampled. The gear rotates exactly 1/64 of a full rotation (5.625 degrees) every game tick - this means that although there would theoretically be many possible frames created by intermediate rotations, only 64 unique frames can ever appear in practice. The resulting gear takes 3.2 seconds to make a full rotation and has 18.75 RPM.

There are two different animations used for gears - one for clockwise rotation, and another for counterclockwise rotation, to allow for logical meshing. These are generated effectively identically, with the only difference being the direction of rotation; both start on the same frame, but cycle through them in the opposite direction.^[1]
