The bug
Boats inside non full level water (see MC-124819) sink even if NoGravity is set to 1b.
How to reproduce
- Create a straight waterfall
- Summon a boat with NoGravity:1b
/summon boat ~ ~ ~ {NoGravity:1b} - Push or steer the boat into the water
It floats or sinks
Code analysis
Based on 1.12.2 decompiled using MCP 9.40
It looks like the reason could be that when a boat has the status EntityBoat.Status.UNDER_FLOWING_WATER, the method net.minecraft.entity.item.EntityBoat.updateMotion() modifies d1 which is added to the y-motion instead of modifying d2.
