- The behaviour as of 1.8.8 is the following:
- - Landing in water alleviates all fall damage
- - Passing through any liquid (water + lava) and cobwebs "slows" the player down,
- i.e. resets the fall distance to that block, but only after checking for fall damage
- (this means that plummeting into lava will still kill the player via fall damage, although cobwebs
- will slow players down enough to have multiple updates that keep them alive)
-
- With this in mind, we first check the block at the player's feet, and decide which behaviour we want to go with.
