How To Reproduce I don't know exactly how to reproduce, but what I can glance from the logs is that it looks like packetevents is still in the process of enabling itself, and my plugin is enabling in parallel. But it's faster (due to being smaller). And so PE hasn't done its full startup routine yet I guess...

Maybe there should be a similar event as in ItemsAdder that triggers "onLoad"?

svaningelgem commented 2 weeks ago

I do this: onEnable:

    private void setupPacketEvents() {
        var plugin = getServer().getPluginManager().getPlugin("packetevents");
        var isEnabled = plugin != null && plugin.isEnabled();

... rest of the init

==> plugin != null ==> isEnabled = false

Add packetevents as a dependency in your plugin.yml

svaningelgem commented 2 weeks ago

Already did that:

depend:
  - packetevents
svaningelgem commented 2 weeks ago

FYI: if I relocate PE into my own plugin, it's working fine...

booky10 commented 2 weeks ago

If you dont shade, dont call the packetevents init methods Also make sure that packetevents is part of your plugin.yml dependencies

svaningelgem commented 2 weeks ago

If you dont shade, dont call the packetevents init methods

I just followed this here: https://packetevents.gitbook.io/docs/creating-your-packetevents-instance

But it doesn't mention shading anywhere? (well, there is a FAQ TODO about it). But looking at the docs, I would say I have to init()?

svaningelgem commented 2 weeks ago

I can confirm that everything works fine as long as I don't use init. So I'm guessing this "bug" becomes a documentation issue?

booky10 commented 1 week ago

Yes. @retrooper this should be added to the docs. The whole "Creating Your PacketEvents Instace" page only applies when shading.
