Events only fired for own player on server

[Renato]

I try to get some information about other players when joining a server. For example, I want to listen to the `AttackEntityEvent` to observe if one player hits another. However, this event works only if my own player hits other entities. 

Also, I want to read the information in the chat on a server with `ClientChatReceivedEvent` but that only works in Singleplayer. I know these problems are kind of separate ones but maybe they are linked because I register my Event listeners in a wrong way. I don't know. 

I have the same problem with many other events like `ArrowNockEvent`, `LivingHurtEvent`. The only event that works correctly is my `TickEvent.PlayerTickEvent`.

Could you help me please. Are these events wrong? If so, are they other events that I can consider? If not, how can I gather information about other players on the server? Thanks for your help!

No idea?

[Paint_Ninja]

I think the events you're looking at are based on client-side information. Depending on where the mod is being run (client-side or server-side) the events may produce different results. You could use networking to communicate server events to the client.

What Forge version are you using?

By the way, try asking on the Discord in future, it's more active for dev support than the forums these days.
