[Solved] RenderLayer not rendering on multiplayer

Oscarita25 · May 25, 2019

Okay i created a RenderLayer it works 100% in SinglePlayer

but it doesn't in multiplayer for other Players

i think its because i use capabilities .. or at least i use them wrong for this :0

so the RenderLayer is shown if (int)capability x of Player is equal to (int)y

@SideOnly(Side.CLIENT)
public class LayerEntityOnPlayerBack implements LayerRenderer<EntityLivingBase>{

    private final RenderManager renderManager;
    protected RenderLivingBase <? extends EntityLivingBase > Renderer;
    private ModelBase Model = new ModelParrot();
    private ResourceLocation Resource = RenderParrot.PARROT_TEXTURES[2];

    public LayerEntityOnPlayerBack(RenderManager rendermanager)
    {
        this.renderManager = rendermanager;
    }

    public void doRenderLayer(EntityLivingBase entitylivingbaseIn, float limbSwing, float limbSwingAmount, float partialTicks, float ageInTicks, float netHeadYaw, float headPitch, float scale)
    {
    	IModelID model = entitylivingbaseIn.getCapability(ModelProvider.MODEL_CAP, null);
    	BNHA.NETWORK.sendToServer(new MessageRequestModel());
    	
    	    	
        if (model.getModelID() == Reference.tail)
        {
            GlStateManager.enableRescaleNormal();
            GlStateManager.color(1.0F, 1.0F, 1.0F, 1.0F);

            	if(Renderer == null) 
            	Renderer = new RenderParrot(this.renderManager);
            	
            	Renderer.bindTexture(Resource);
            	
            	
                GlStateManager.pushMatrix();
                float f = entitylivingbaseIn.isSneaking() ? -1.3F : -1.5F;
                GlStateManager.translate(0.0F, f, 0.0F);
                
                ageInTicks = 0.0F;

                Model.setLivingAnimations(entitylivingbaseIn, limbSwing, limbSwingAmount, partialTicks);
                Model.setRotationAngles(limbSwing, limbSwingAmount, ageInTicks, netHeadYaw, headPitch, scale, entitylivingbaseIn);
                Model.render(entitylivingbaseIn, limbSwing, limbSwingAmount, ageInTicks, netHeadYaw, headPitch, scale);
                GlStateManager.popMatrix();
            

            GlStateManager.disableRescaleNormal();
        }
  }

    public boolean shouldCombineTextures()
    {
        return false;
    }
}

Good dear lord.

You do understand that you are sending a packet to a server EACH FRAME with this code, right?

Do not ever do that. That is probably the worst thing you could do.

In addition a request packet is an indication of a bad design. The server knows exactly who needs the data and when to send it. Don't request packets from the client.

In addition your approach wouldn't work anyway because packets are handled by a different thread, meanung your rendering code just moves onwards without receiving the data from the server.

But why do this if you can just get the existing renderer for the parrot?

I don't think yu need to normalize the normal vectors here, so enable/disableRescaleNormal is not needed.

How are you syncing the capability to the players involved? Show that bit of your code.

Oscarita25 · May 25, 2019

i am making the a new Renderer because i just use the parrot as placeholder i will replace it with a model of my own

and you mean like the Packet class of where i am syncing the caps?

V0idWa1k3r · May 25, 2019

The handler is the one I am interested in, although the best case scenario is all of them.

Oscarita25 · May 25, 2019

Here the Github repo so you can browse trough:

(figured that this would be faster than copy pasting code)

Github BNHA Mod

Layer class

Model ID Message Server

Model ID Message Client

Hope that helps also if i do the Packets wrong tell me how to do them right because i am quite sure i am doing them quite wierd and not very optimized...

public static CommonProxy proxy;

A CommonProxy makes no sense. Proxies exist to separate sided-only code, if your code is common then it goes anywhere else but your proxy.

Quote

serverSide = Reference.COMMON_PROXY_CLASS

This makes even less sense. A server proxy contains either NOOP implementations for client-only things or code that would crash the client. Your common proxy can't be your server proxy.

Why do you have multiple methods both subscribing to the same FMLLifecycle event? Why not use just one method?

https://github.com/Oscarita25/BNHA/blob/master/src/main/java/com/oscar/data/packets/MessageQuirkID.java#L36

You can't do this, your handler is common, but this is client-only code. This will crash the server. You must use a proxy.

Quote

public class MessageRequest...

Just no. Get rid of all of your request messages. First of all the server knows when to send the data, so send it from the server when needed, don't ask the client. Second of all the client can and WILL abuse these request messages. Finally this is just extra network IO that wastes time.

https://github.com/Oscarita25/BNHA/blob/master/src/main/java/com/oscar/data/packets/MessageRequestActivate.java#L64

Since you have no safety checks and just blindly trust the client a malicious client can easily abuse this packet to do whatever it wants, like cover the entire world in these entities, one per block.

The reason for your issue is that you only ever set the capability data for the model to the main client player. If you need the model data for another player then set it in their capability instance, not in the client's player.

https://github.com/Oscarita25/BNHA/blob/master/src/main/java/com/oscar/init/ModItems.java#L38

Don't ever use static initializers for registry entries. Registry entries MUST be instantinated in the appropriate registy event. Using static initializers can and WILL cause issues.

https://github.com/Oscarita25/BNHA/blob/master/src/main/java/com/oscar/items/ItemBase.java

ItemBase is pointless, there is already an ItemBase, it's called Item. Don't abuse inheritance.

Quote

implements IHasModel

IHasModel is the worst thing to ever exist on this planet. It is ugly, doesn't make any sense since all items need models anyway, makes you write extra code and makes your code that much harder to manage. Don't use it and just register your models in the modelregistryevent directly.

https://github.com/Oscarita25/BNHA/blob/master/src/main/java/com/oscar/util/LoggingUtil.java

Any reason for this class to exist? Like at all?

What is NOOP? yeah i understand that and i wanted to change that for a while just forgot about it because .. if it works it works (i will change it later)

i actually i can because those packets are registered for client side and won't be actually executed on server side! (i tested it on server it won't cause issues)

should i just delete the static intializers or should do it entirely different (code example if possible)

No Operation, do nothing.

It works for now, but it may and likely will cause issues later. Do you want to do a quick reactoring now or restructure half of your mod later?

This doesn't matter. It's client-only code in a common environment. Yes, vanilla JVM won't load classes before it gets to their execution without any special flags I believe. Vanilla JVM isn't the only one though, and other implementations may do different things.

Besides there are still ways to load that code on a server and cause a crash.

So no, you really can't and it will cause issues.

Just send the data from the server when the client needs it. The actual implementation would differ but as an example of your model capability you would send it to the player when they log in or when the data changes.

10 minutes ago, Oscarita25 said:

That would depend on your implementation. There should be a limit to these interactions anyway, like a cooldown or something. But that's up to you.

10 minutes ago, Oscarita25 said:

Delete the static initializers and just instantinate your things in the registry event. That's it. There is no example needed - do you need an example of writing new Item...() ?

Oscarita25 · May 26, 2019

so @V0idWa1k3r i did pretty much fix the proxy and the items(i think) and am now stuck on the packets :0

so now at this point i am wondering how should i do it correctly because i used my packets as request and reply :0

V0idWa1k3r · May 26, 2019

Just send them whenever the client needs them. You know when they need it.

If you have a capability you want to sync then send the packet every time the player logs in or the data changes.

In case of the model capability data you would want to send it every time a player started to track another player - grab the other player and send it to the tracking player.

Oscarita25 · May 26, 2019

also just asking bc i did this like really fast:

public class ModItems {
	
	

	//Materials
	public static final ItemArmor.ArmorMaterial UA_SPORTS_MAT = 
			EnumHelper.addArmorMaterial
         (Reference.MOD_ID +":ua_sports",Reference.MOD_ID +":ua_sports",15,
		 new int[]{1, 4, 5, 2},12,SoundEvents.ITEM_ARMOR_EQUIP_LEATHER,(float) 0);	
	
	public static  final ItemArmor.ArmorMaterial BAKUGO_ARMOR_MAT =
			EnumHelper.addArmorMaterial
		 (Reference.MOD_ID +":bakugo_armor",Reference.MOD_ID +":bakugo_armor",15,
		 new int[]{1, 4, 5, 2},12,SoundEvents.ITEM_ARMOR_EQUIP_LEATHER,(float) 0);
	
	public static final ItemArmor.ArmorMaterial DEKU_ARMOR_MAT =
			EnumHelper.addArmorMaterial
		 (Reference.MOD_ID +":deku_armor",Reference.MOD_ID +":deku_armor",15,
		 new int[]{1, 4, 5, 2},12,SoundEvents.ITEM_ARMOR_EQUIP_LEATHER,(float) 0);
	

	public static final Item[] ITEMS = {
			new ClothArmor("ua_sports_chestplate",UA_SPORTS_MAT,1,EntityEquipmentSlot.CHEST),
			new ClothArmor("ua_sports_leggings",UA_SPORTS_MAT,2,EntityEquipmentSlot.LEGS),
			new ClothArmor("deku_armor_chestplate",DEKU_ARMOR_MAT,1,EntityEquipmentSlot.CHEST),
			new ClothArmor("deku_armor_leggings",DEKU_ARMOR_MAT,2,EntityEquipmentSlot.LEGS),
			new ClothArmor("deku_armor_feet",DEKU_ARMOR_MAT,1,EntityEquipmentSlot.FEET),
			new ClothArmor("bakugo_armor_head",BAKUGO_ARMOR_MAT,1,EntityEquipmentSlot.HEAD),
			new ClothArmor("bakugo_armor_chestplate",BAKUGO_ARMOR_MAT,1,EntityEquipmentSlot.CHEST),
			new ClothArmor("bakugo_armor_leggings",BAKUGO_ARMOR_MAT,2,EntityEquipmentSlot.LEGS),
			new ClothArmor("bakugo_armor_feet",BAKUGO_ARMOR_MAT,1,EntityEquipmentSlot.FEET)
	};

}

@Mod.EventBusSubscriber(modid = Reference.MOD_ID)
public class RegistryHandler {
	
	
	@SubscribeEvent
	public static void onItemRegister(RegistryEvent.Register<Item> event) {
		event.getRegistry().registerAll(ModItems.ITEMS);
		
		LoggingUtil.BNHALogger.info("Registered Items");
	}

	@SubscribeEvent
	public static void registerModels(ModelRegistryEvent event)
	{
		
		for (Item item: ModItems.ITEMS)
		{
			ModelLoader.setCustomModelResourceLocation(item, 0, new ModelResourceLocation(item.getRegistryName(), "inventory"));
		}
		
		LoggingUtil.BNHALogger.info("Registered models");
	}


}

is this the right way to register it? - just asking because i am not sure

(just saying i am on basic level of item registering because i pretty much avoid making items at all)

No, you have changed NOTHING. Putting your stuff in an array doesn't change the fact that it is still created in a static initalizer.

Instantinate your stuff in the appropriate registry event as I've already said. Not anywhere else.

if i got it right ...

			new ClothArmor("ua_sports_chestplate",UA_SPORTS_MAT,1,EntityEquipmentSlot.CHEST),
			new ClothArmor("ua_sports_leggings",UA_SPORTS_MAT,2,EntityEquipmentSlot.LEGS),
			new ClothArmor("deku_armor_chestplate",DEKU_ARMOR_MAT,1,EntityEquipmentSlot.CHEST),

			new ClothArmor("bakugo_armor_head",BAKUGO_ARMOR_MAT,1,EntityEquipmentSlot.HEAD),
			new ClothArmor("bakugo_armor_chestplate",BAKUGO_ARMOR_MAT,1,EntityEquipmentSlot.CHEST),
			new ClothArmor("bakugo_armor_leggings",BAKUGO_ARMOR_MAT,2,EntityEquipmentSlot.LEGS),
			new ClothArmor("bakugo_armor_feet",BAKUGO_ARMOR_MAT,1,EntityEquipmentSlot.FEET)

this right into the registry?

V0idWa1k3r · May 26, 2019

Yep

then 1 question how do Instantinate it?

V0idWa1k3r · May 26, 2019

Instantinating means creating a new instance.

So when you write new Thing(,,,) you are instantinating Thing.

Use the ObjectHolder annotation

    @GameRegistry.ObjectHolder(value = "ua_sports_chestplate")
    public static final Item UA_SPORTS_CHEST = null;

like this?

V0idWa1k3r · May 26, 2019

You don't have to write the value = part, but sure.

Just make sure the domain of your mod is provided somehow, either in said value or in the annotation on the class itself

https://mcforge.readthedocs.io/en/latest/concepts/registries/#injecting-registry-values-into-fields

Oscarita25 · May 26, 2019

then 1 last question can i use the object holder to register the model to or do i have to that differently?

V0idWa1k3r · May 26, 2019

It would be easiest to do with a one-line stream

Pseudo-code:

ForgeRegistries.ITEMS.valueCollection().stream().filter(i -> i.getRegistryName().getDomain().equals(MYMODID)).foreach(i -> ModelRegistry.setCustomModelResourceLocation(...))
