[1.11] EntityJoinedWorldEvent Ticking memory connection


Lambda

Recommended Posts

Hey there,

 

I'm trying to sync a value when the player joins the game, however, using

EntityJoinedWorldEvent

seems to cause this on join:

// Why did you do that?

Here is the event:

    @SubscribeEvent
    public static void EntityJoinedWorldEvent(EntityJoinWorldEvent event) {
        Minecraft mc = Minecraft.getMinecraft();
        if(event.getEntity() instanceof EntityPlayer) {
            if (mc.thePlayer.hasCapability(CapabilityMagic.MANA, null)) {
                CapabilityManaData cap = mc.thePlayer.getCapability(CapabilityMagic.MANA, null);
                if (!event.isCancelable()) {
                    PlentifulMisc.network.sendTo(new ManaNetworkSyncClient(cap.getManaStored()), (EntityPlayerMP) cap.getEntity());
                }
            }
        }
    }

Why are you checking event.isCancelable() at all?

 

That said, why are you using Minecraft mc = Minecraft.getMinecraft(); on the server?  And why are you getting the player from the client side class rather than from the event? You check event.getEntity() to see if it's a player...

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

Seriously?

 

if(event.getEntity() instanceof EntityPlayer) {
    EntityPlayer player = (EntityPlayer)event.getEntity();
}

 

Fuck.
