- Added Shulker Box - 1×1×1 collision box, can extend by 0.5b when opened with right click.
- The extension increases and decreases by increments of 0.05b every tick.
- The shulker box can only be opened if it doesn't end up intersecting with another collision box.
- Interestingly, the opening starts with a surplus of 0.01b, which means the player is actually pushed 0.51b.
At the end of the opening animation, the extension's length is brought back to 0.5b.
