-Blocks by themselves aren't that interesting, they just stay static at a certain location and a certain size until broken. We can use block entity renderers to render items and blocks associated with a block entity far more dynamically - render multiple different items, at differing locations and sizes, and more.  +Blocks by themselves aren't that interesting, they just stay static at a certain location and a certain size until broken.

 In this tutorial we'll build off the block entity we created by adding a ''BlockEntityRenderer'' to it. The renderer will display a jukebox floating above the block, going up and down and spinning.   In this tutorial we'll build off the block entity we created by adding a ''BlockEntityRenderer'' to it.

 We're going to need to register our ''BlockEntityRenderer'', but only for the client. This wouldn't matter in a single-player setting, since the server runs in the same process as the client. However, in a multiplayer setting, where the server runs in a different process than the client, the server code has no concept of a "BlockEntityRenderer", and as a result would not accept registering one. To run initialization code only for the client, we need to setup a ''client'' entrypoint.   We're going to need to register our ''BlockEntityRenderer'', but only for the client.

-We then perform the movement of the jukebox (matrices.translate) and rotation (matrices.multiply). There are two parts to the translation: we translate it to 0.5, 1.25, and 0.5 which is above the center of our block. The second part is the part that changes: the offset in the y value. The offset is the height of the item for any given frame. We recalculate this each time because we want it to be animating bouncing up and down.

We use this because otherwise the animation would be jittery because there are fewer ticks per second than frames per second.)   * Adding the partial ticks.
