Minecraft 1.13 Snapshot 18w10c (New Water Physics)

Minecraft 1.13 Snapshot 18w10c has new underwater physics! slabs, stairs, iron bars, glass panes, fence gates and fence posts can be placed underwater.

Features:

Phantoms are now considered undead.

New water physics! Kinda.

Water physics:

You can place water in the following blocks: stairs, slabs, fences, walls, iron bars, glass panes.

Water can flow out these blocks, but can not flow into them.

When full of water, they will count as water blocks for all gameplay (such as swimming).

This isn’t final and more blocks may contain water in the future.

Right now it will flow out of all faces of the block – this will change.

Removed the blocks flowing_water and flowing_lava.

Removed the block tags water_hacked and waterlogged.

All of the above blocks now have a state waterlogged.

Blocks such as bubble column or kelp will always count as a water source.
