Hello,

 

I’m trying to store a per-entity int using capabilities, which seems to be working. The problem I have is accessing them form the model file. entityIn.getcapability seems to only return the default capability values I’ve set. Any suggestions? 

You need to synchronize the capability from the server to the client yourself.

Okay, now I'm confused on what goes in this method. How can I send the player capability data?

@Override
        public IMessage onMessage(MessageUpdateClientTardis message, MessageContext ctx) {
            EntityPlayerMP serverPlayer = ctx.getServerHandler().player;
            serverPlayer.getServerWorld().addScheduledTask(() -> {
                
            });
        return null;
    }

 

I've done the toBytes and fromBytes. I'm just not sure how to copy it to the client-side instance, since there isn't much documentation on it.

Well, how can there be documentation, if it's your code?
And you certainly know how to copy data from one field to another, right?

I think he probably means that from the message class, how do you figure out the world and thus the entities instances available to match against.

 

I'm not entirely sure it is the best way, but I used to do the following in a mod. Note that getting entity by ID might have changed in more recent versions. In the message from server to client, in the onMessage() method I would get the player from the context then the world from that as follows:

 

EntityPlayer thePlayer = MainMod.proxy.getPlayerEntityFromContext(ctx);
Entity theEntity = thePlayer.world.getEntityByID(message.entityId);

 

Where in my proxy I had the getPlayerEntityFromContext() method as follows for client proxy:

    public EntityPlayer getPlayerEntityFromContext(MessageContext ctx)
    {
        return (ctx.side.isClient() ? Minecraft.getMinecraft().player : super.getPlayerEntityFromContext(ctx));
    }

And in my common proxy had:

    public EntityPlayer getPlayerEntityFromContext(MessageContext ctx)
    {
        return ctx.getServerHandler().player;
    }

Why you would ever have to pass that through your proxy, I don't know. You already know which side it's on as packets should only go one way: it's sent from the server to the client, the packet handler therefor only exists on the client and it's safe to use Minecraft.getMinecraft()

Likewise, going the other way.

Packet handlers always exist on both sides.

Hmm. My mental model must be out of date. I just checked and I'm running stuff through my proxy as well.

Never mind.
