Issue Description

Animals turn into vampires randomly without being bitten by a vampire.
Can't have animal farm when they suddenly turn into vampire versions and attack other animals.
I have used name tag on the animals.

Reproduce Steps

Leave animals in a 5x3x5 closed room that is lit.

Additional Information

This might be related to: #249

The bounding box of the bite radius was a little high, he reduced it. Hasn't been released yet though.

It should be impossible to turn without being bitten.

As iamtpage mentioned, vampires might be (or have been) able to bite through fences or through corner blocks.

But you are saying to enclosed them within solid blocks? That is strange, I will have a look, but #249 would probably have fixed that issue as well.

Glass pane solid? Then yes.

Light levels

Inside my base is also 100% lit so there's no spawn points for mobs and they can't get to the glass pane side at all.

Glass panes are solid, but due to bounding boxes (until the new update is released) if an animal is directly against it, the vampire would be able to bite it through the glass

Try a solid glass block, not a glass pane

I tried putting two extra layers of blocks on the stone brick wall and there hasn't been any vampire animals since then. So it seems like they got bitten trough the stone bricks.

There should be a new recommend build (1.3.7) shortly, please check if that actually solves this issue

Ok, the bite algorithm is indeed a little bit messy/inconsistent in v1.3.5, so it might have been possible for vampires to bite through stone walls if they happen to stand next to a wall with entities behind.
After the adjustments made for #249 and here, the behaviour is still slightly inconsistent, but the remaining issues should be ok:

• Blocks thicker than half a block as well as any non see through block should prevent entities from being bitten.
• One layer of fences is not enough. Vampires won't actively try to reach any entity inside, but if they happen to stand very close they can bite the entities (this makes more or less sense as discussed in #249)
• Glass panes may not be enough. Vampires won't actively try to reach any entity inside, but it is not guaranteed that the entities are safe if the vampire happens to stand near. (Due to the way Minecraft works this would take quite a lot of effort to prevent)

Thank you for reporting and let me know if you should face any issues regarding this with future versions
