Hey, i was updating from 1.8 with IEEP to 1.10 with Capabilities, but everything I've done seem to add a copy of my mana, an un usable version of it. I ran a debug system print of the mana value, it rejuvenates as you would expect it too over time, but a ghost value renders over my mana bar and not the value that keeps changing when i right click the item

 

The ghost value rejuvenates as well but it gets to 10, like the bar is supposed too but wont go down when i use the item, the main value does go down when i use it though, its like when i right click the item, the value gets used, then the ghost value is dominate as the bar rending code uses that value instead.

@Override
public ActionResult<ItemStack> onItemRightClick(ItemStack stack, World world, EntityPlayer player, EnumHand hand) {  
        final IEssenceBar bar1 = player.getCapability(BarTickHandler.ESSENCE_CAP, null);
	if(!world.isRemote && bar1.useBar(usage)) {
		//ENTITY SPAWN CODE
	}
}

Capabilities aren't automatically synced, do you ever sync the mana value from the server to the client?

do you mean the read/write NBTBase method?

do you mean the read/write NBTBase method?

 

That is "save to disk" not "send packets" it's right there in the name. "Packets."

Ive really not had much to do with Packets

They're super easy.

Also should state that that code changes things, the bar rendering starts to spazz, changes from rendering the ghost value to the normal value every tick

Looks like you've made some progress which is good. Do you have your project on a public repo? (GitHub, Bitbucket)

I'd be happy to assist the best I can, if you like you can have a look at my capability system https://bitbucket.org/hugo_the_dwarf/riseoftristram2016/src?at=master packages are named in meaningful ways

 

Was those 3 posted blocks of code you're only changes? or have you updated your bar tick code since then?

Here is the github

I've noticed in your Essence class you use Journey.wrapper.sendToAll() just curious if you mean to do that. Because you register your Capability on "Everything" not just players. But I don't see any "generic" entity tick so it rules out the fact that a random mob could be "sending" it's data to everyone.

 

However that sendToAll() will cause issues because you use your clientProxy to "handle" the data by getting the minecraft.thePlayer which If player 1 ticked and updated, server sends data to all, player 2 now thinks "player 1s" stats are his (then player 2 gets ticked, and server updates all players again player 1 now thinks player 2's stats are his)

 

if you make sure in the player tick event you can just use Journey.wrapper.sendTo(message,(EntityPlayerMP) player); and it will send it to the correct player rather than all players.

 

I'm still digging through some of your code.

The thing is i dont have a instance to EntityPlayer in the Essence class, i could make a constructor in the class getting one, but i dont create an instance for the  Essence class either, its constructed from the default instance method, and even if i wanted to change that, where i register my class in the BarTickHandler i dont have a player instance either so thats another problem, i could use Minecraft.getMinecraft().thePlayer but thats a SP instance and i want MP

Update some of your methods that "send a packet" to include a EntityPlayer param, and in your PlayerTick events you can get the player from there

 

if (!player.worldObj.isRemote)

essence.mainUpdate(player);

 

^^^

 

Journey.wrapper.sendTo(new MessageEssenceBar(essence, regenDelay == 0),(EntityPlayerMP)player);

 

or you can just declare an Entity obj in the Essence class and give your provider a constructor or have it call capability.entity = event.entity

 

then in main updates you just check to see if the entities worldObj is not remote (server) and sendTo from there.

 

Since I can't physically see the ghosting or debug and step through (I might just do a pull and run it personally soon enough) to see what it really could be.

 

EDIT: looks like you have a Console.out somewhere sending out the values which is nice, as I can see numbers flying all over. If I can locate that spot I can try having the console also pump out hopefully any other helpful information.

I think its fixed now, i added a player parameter to the methods and seemed to fix it all

 

	if(player instanceof EntityPlayerMP) Journey.wrapper.sendTo(new MessageEssenceBar(essence, regenDelay == 0), (EntityPlayerMP)player);

 

also did that, thanks!
