Unexpected blaze flying behaviour

emilcarr commented 3 years ago

What behaviour is expected:

Vanilla blaze behaviour is for blazes to fly when targeting a player and fall down otherwise. Player is within activation range of blazes.

What behaviour is observed:

Blazes fly intermittently even when not targeting any player.

Steps/models to reproduce:

Build (sponge schem) a 9x9x5 box with a blaze spawner in the middle and a lava funnel below. Allow blazes to spawn and observe behaviour.

Plugin list:

Dynmap v3.1

Paper version:

[CHAT] This server is running Paper version git-Paper-497 (MC: 1.16.5) (Implementing API version 1.16.5-R0.1-SNAPSHOT)

[CHAT] Previous version: git-Paper-468 (MC: 1.16.5)
04:36:28.548
[CHAT] You are 29 version(s) behind

Anything else:

I compared the PaperSpigot sources to vanilla Minecraft decompiled with yarn mappings, and the behaviour in tick() and tickMovement() BlazeEntity/EntityBlaze have no discrepancies I can see that would result in this behaviour.

Works as intended. Blazes do not instantly fall down, it will take them a few seconds.

Apologies Proxymist, but that's not the behaviour I observed. The blazes flew 'intermittently', as in falling down then flying back up when I wouldn't expect.

emilcarr commented 3 years ago

I will try on a newer version of the server.

Proximyst commented 3 years ago

Will attempt to reproduce later today.

I'm now struggling to recreate this on a clean server setup - bear with me

Couldn't recreate the issue on a separate server. Server owned has updated server version. Issue is fixed. My apologies.
