Drowned spawns in blocklightDrowned spawns in block-light
Summary:
In 1.18.0 and after, Drowned seems to spawn in condition [sky-light<=7 && block-light<=7].
Since 1.18.0, I understand as that Hostile mobs spawn in [sky-light<=7 && block-light=0].
- Hostile mobs spawn only in areas where the light level is equal to 0. (This change affects only block-light and not sky-light.)
Surface mobs spawn only in areas where non block-light, as expected.
And in Java Edition, Drowned spawns in non block-light, too.Step to reproduce:
- Set time to daytime. (sky-light = 15)
- Prepare water 4 blocks in depth. (sky-light level of bottom of water = 15-2-2-2-2 = 7)
- Fill bottom of water with glow-lichen. (block-light level = 7)
Observed results:
Drowned spawns on bottom of water.
Expected results:
Drowned doesn't spawn. (because there are no blocks to fulfill the condition)



The conditions tested in this video were midnight, clear weather, River biome.
I also tested in other condition such as thunder, day, noon, Ocean biome, all with the same results.

Affect 1.18.2
I confirmed that the extra "half a heart" is False health.
When player take damage after this issue, "True health value" is displayed until next natural regeneration.
("True health value" is affected by
MCPE-36131Taking damage is sometimes negated by natural regeneration.)For example, in situation of water drowning:
True health:
10 -> 9 -> 8 -> 7 -> 6 -> 6.5 (
MCPE-36131and 0.5 natural regenerated) -> 5.5 (1 damaged)Displayed health:
10 -> 9 -> 8 -> 7 -> 6 -> 7 (
MCPE-36131and 1 regenerated by this issue) -> 5.5 (True health is displayed by damaging)And I think "Players health naturally regenerates 1 heart every 4 second" is not exactly.
After this issue is started, stop taking damage. (As example, getting out of water)
Then, subsequent natural regenerations are half a heart every 4 second.
For example, in situation of water drowning:
True health:
10 -> 9 -> 8 -> 7 -> 6 -> 6.5 (
MCPE-36131and 0.5 natural regenerated) -> (stop drowning) -> 7 (0.5 natural regenerated)Displayed health:
10 -> 9 -> 8 -> 7 -> 6 -> 7 (
MCPE-36131and 1 regenerated by this issue) -> (stop drowning) -> 7.5 (0.5 natural regenerated)However, the first natural regeneration after "True health value" is displayed by taking damage, then "Players health naturally regenerates 1 heart" again.
This state finishes when natural regeneration is ended by low saturation.
True health:
6.5 (not under issue) -> 6 (0.5 damaged by something) -> 6.5 (0.5 natural regenerated)
Displayed health:
7 (under this issue) -> 6 (True health is displayed by damaging) -> 7 (1 regenerated by this issue again)
Additionally, I confirmed that this issue is not caused by "regeneration" status effect. It only causes
MCPE-36131.Affected 1.18.10
in beta (preview) v1.18.30.21, this issue is no longer reproduced.

It seems this issue is no longer reproduced.
It seems to be fixed. Thank you!
