PlayerDeathEvent

It seems like PlayerDeathEvent is not working. Is it just for me or is this happening to someone else?

How is it "not working"? Please be more specific.

It's more likely that your code is wrong instead of PocketMine working incorrectly.

Than I guess evolsoft and praxthisnovcht have bad code as well. KillChat by praxthisnovcht isn't adding kills when player dies, CustomAlerts isn't broadcasting messages and my plugin isn't adding money when one players kills the other.

That does't mean they have bad code. Perhaps you did not set KillChat and CustomAlerts up correctly.

Hm, really! Event is not working... After update my mini game on my server. But on 112x build working, on 113x not working this event. This really stranlgy.

Maybe others plugins using EntityDeathEvent and there are working with this.

A software will never be perfect especially for big softwares otherwise GitHub issues, bugs, bugfix updates, bug reporting tools wouldn't exist.
However if you find bugs with one of my plugin, you can simply ask me or post an issue on GitHub

Y = 0 is a player pos or...?

It's when they go below bedrock (0).

That's weird. I haven't seen a player go below bedrock.

I think so to

CustomChat by praxthisnovcht was causing this error, It might have some bugs.
