[1.12] Help with registering entity into game

[Big_Bad_E]

Hello, I am working on a creepypasta mod in which there is a mob, but in 1.12 I can not seem to get my entity to render into the game, I do /summon Entity303 and it returns an error.

/Summon Error

I have looked at Entity tutorials and couldn't find what is wrong. I believe there is multiple errors, so tell me all the ones you find. I may of messed up on giving the entity an ID, and I tried putting

RenderingRegistry.registerEntityRenderingHandler(EntitySerpent.class, 
      new RenderSerpent(new ModelSerpent(), 0.5F));

into my client proxy preInit but registerEntityRenderingHandler was crossed out and the new Render said it needed another argument. (I copied this out of a tutorial)

Thank you for reading this!

Well, your main class is useless, nothing of any worth is there (oh, you need it, it just doesn't help solve your problem what so ever because it forwards everything to the proxy classes which you didn't include).

 

You have a registerGlobalEntityID() method in your entity class, which is both useless (it does nothing) and implies you're doing things Wrong. You should not be using global IDs.

 

Third, /summon Entity303 isn't correct. This implies the default domain, minecraft, which your mod is not a part of. You would need /summon MODID:Entity303 using whatever your MODID actually is.

 

Fourth, this is a forum, not a chat room. 37 minutes is hardly people ignoring your thread. Jesus, wait a bit.

First of all, I included the main class just in case anyone needed it, but I didn't include the proxys because there was nothing there relevant, and the main class is, well the main class

 

Second, I was trying to do that because I was out of ideas

 

Third, I tried that and /summon Entity303, they are the same thing. You can do /summon without the mod id unless the names overlap.

 

Fourth, it was a joke, my thread was already at the top, I posted this at like 9:30, there wasn't any need to bump it.

 

Also, I am not looking to be told this thread is not a chat room, I came here looking for help and not how to post a tread

The main class does nothing but pass the FML lifecycle events to the proxy. If the proxy is likewise useless, then you aren't registering your entity at all.

There, you happy? I don't have anything in there, because like I said I haven't registered it in the proxy because the method that I know isn't for 1.12, as I stated in the post above. if you know the method, please tell me it.

None of the classes you have posted are the RegistryHandler class. Feel free to ctrl-F that yourself.

[Big_Bad_E]

I named it Entity303Registry not RegistryHandler, if I need a class called RegistryHandler, I didn't realize, but that is every class I have.

Both of the proxy classes you posted reference a class called RegistryHandler. Neither of them reference Entity303Registry.

 

You haven't posted a class called Entity303Registry.

[Big_Bad_E]

Ok so I have been zipping around tutorials trying to figure out how to set up the mod, and did that. I will fix it, sorry I was so confused.

[Big_Bad_E]

So Now I need to use the LoadEntityRenders method, but I don't know what the different arguments are. I have my renderManager working, and everything else is dandy, except for it. (I got a different method to work, but it crashed my game.)

Still won't summon

[Draco18s]

you aren't registering the entity itself, only a renderer for it. 

[Big_Bad_E]

Ok, so what are you telling me, I register the Entity ID, and you tell me that's wrong, but that's how you register it. What is the proper method?

[Draco18s]

Let me put it this way:

 

Where are you calling EntityRegistry.registerModEntity?

[Big_Bad_E]

Yes, I don't know how to call upon EntityRegistry.registerModEntity! Thanks for the response, but my question is how to use it. I tried

EntityRegistry.registerModEntity(null, Entity303.class,null, 200, renderManager, 0, 0, false);

Into my RegistryHandler and it crashes

Sorry if I've been annoying/stupid, I have never been on a forum, and I am generally new to Java/Forge, and newer to Forge 1.12.

 

 

[Choonster]

Passing null as an argument that isn't explicitly documented or annotated as nullable is a bad idea. You need to pass actual values for the registryName and entityName arguments.

 

The registryName argument of EntityRegistry.registerModEntity is the registry name of the entity, which must be a unique name with your mod ID as the domain of the ResourceLocation and the entity's name as the path. The registry name is used as your entity's ID when it's being read from/written to NBT.

 

The entityName argument of EntityRegistry.registerModEntity is a separate name for the entity, which should also be unique (i.e. you should include your mod ID in it). This is sometimes called the "old" name and is mainly used for translation/display purposes. I recommend using the registry name for this name, but it's not required to do so.

Ok,I get what your saying, but I get an error on my entityName and registryName, For now my code is like this:

package Entity303;

import net.minecraft.client.Minecraft;
import net.minecraft.client.renderer.entity.RenderManager;
import net.minecraft.entity.Entity;
import net.minecraft.util.ResourceLocation;
import net.minecraftforge.fml.common.registry.EntityRegistry;
import Entity303.Entity.Entity303;
import Entity303.Entity.ModelEntity303;
import Entity303.Entity.RenderEntity303;

public class RegistryHandler {
	public static void Client() {
		RenderManager renderManager = Minecraft.getMinecraft().getRenderManager();
        renderManager.entityRenderMap.put(Entity303.class, new RenderEntity303(renderManager, new ModelEntity303(), 0));
		EntityRegistry.registerModEntity(entEntity303, Entity303.class, Entity303, 200, renderManager, 0, 0, false);
	}
	public static void Common() {
		
	}
}

I think I am supposed to put the EntityRegistry in a Public Static or something like that, or do I just put the arguments in the public static void Client()?

Do you actually know Java? You can't just type an arbitrary name like that, you need to pass the method a ResourceLocation and a String.

 

The ResourceLocation must have your mod ID as the domain. If you don't specify a domain, it defaults to minecraft.

 

Entity registration must happen on both physical sides, so it should be done in your @Mod class or a class called from it.

 

Render registration must be done by calling RenderingRegistry.registerEntityRenderingHandler(Class<T>, IRenderFactory<? super T>) in preInit. This must happen only on the physical client, so it should be done in your client proxy or a client-only class called from it.

I am trying to learn it, but no I have no prior java experience, I know it really makes it harder on everyone else, and I am sorry, and I also tried to specify it as a string but because I was in the wrong class it returned an error.

I got all the variables seemingly working, but I get a crash

EntityRegistry.registerModEntity has nothing to do with rendering/textures. It belongs in common code, not client-only code.

 

The registryName argument is a registry name, not a texture path.

 

The entityName argument should include your mod ID.

 

The mod argument is the instance of your @Mod class, but you're passing the RenderManager instance (which is still null in preInit) instead. This isn't a mod instance, so the game crashes with a NullPointerException when Forge tries to get the mod ID to write to the log.

Ok I am so sorry I am so confused, but I have no idea what to do, Can you give me an example of, like if a mod had a mod ID of Hi and the entity is called Smiley, the main class is called HI, and the Entity class is smiley. What would that be? Again, I'm sorry but I am have no idea, and I feel like i'm so close!

EntityRegistry.registerModEntity(new ResourceLocation("hi","smile"), Entity303.class, "smile", 200, renderManager, 0, 0, false);
