fix 50 millis delay between hit and velocity

What is packet.a()? I didn't find that method, could you point it a bit more clear?

[Awamo]

NetworkManager -> protected void a

[amadeusmz]

There is an update velocity code block in EntityTrackerEntry#track(List<EntityHuman> list), ( if (this.tracker.velocityChanged)), to fix this issue I move them to the main thread.
Also, calling PlayerVelocityEvent asynchronously may cause server crash.

@Awamo so what is 'set to true'?? I didn't saw any method accept a boolean argument there nor return type.

@MClausz I didn't call that method asynchronously, and since its caller is EntityTracker#updatePlayers() this method will be called every tick for every world, I don't think there is any extra delay compared with vanilla.

[Awamo]

so go to Packet Class and you will get a boolean at the end of the code (i think boolean a) and you will get a return, just set it to true, and override the method ;)
sorry for answering so late

@Awamo which packet class? in networkmanager it's an interface....

I checked it again, there is default a() in 1.13.2, but not in 1.12.2. However, it's only used for exception handlers. I also did some test, idk how this thing reduces the delay.
