[1.15.1] How to make a custom entity?


DragonITA

Recommended Posts

Hi, sorry for this late reply! I dont know exactly how to Java syntax work if a error was found. Lua Syntax will stop the script (here it is the .class or the .java) if a error was found then the code dont continue and i muss rerun the script in eclipse. This take some time. Ok, why i say this? I say this then i have a Problem with my custom BlockItem. I want first resolve this Problem and then show the code.

P.S.: I need a little bit of time to refind the code.

Edit: Resolved

Java is a static language. It has to compile before running. There must be no syntax errors.

However, it sounds like you are struggling with basic Java syntax. Please learn Java before making a mod, as not knowing Java will cause unnecessary confusions.

1. Do not follow tutorials on YouTube, especially TechnoVision (previously called Loremaster) and HarryTalks, due to their promotion of bad practice and usage of outdated code.

2. Always post your code.

3. Never copy and paste code. You won't learn anything from doing that.

Thanks, i am trying to learn Java. I know a little bit the Heritage of the Java syntax. Here is on how i actualy make my entity (i have tried to find the Init Folder in the Vanilla Code to see hoz i should register my entities, but i cant find it. So I tried to watch a video of HarryTalks with version 1.14.4 to go further. But I get an error, have tried to solve it with my current knowledge, but I can't get it right.) Here is my current Code:

 

package mod.dragonita.fantasymod.entities;

import mod.dragonita.fantasymod.init.FantasyModEntities;
import net.minecraft.entity.EntityType;
import net.minecraft.entity.SharedMonsterAttributes;
import net.minecraft.entity.ai.goal.LookAtGoal;

import net.minecraft.entity.passive.horse.HorseEntity;
import net.minecraft.entity.player.PlayerEntity;
import net.minecraft.world.World;

public class UnicornEntity extends HorseEntity{
	
	@SuppressWarnings("unchecked")
	public UnicornEntity(EntityType<? extends HorseEntity> type, World worldIn) {
		super((EntityType<? extends HorseEntity>) FantasyModEntities.UNICORN_ENTITY, worldIn);
	}

	protected void registerGoals()
	{
		this.goalSelector.addGoal(1, new PanicGoal(this, 1.2D));
		this.goalSelector.addGoal(6, new WaterAvoidingRandomWalkingGoal(this, 0.7D));
		this.goalSelector.addGoal(7, new LookAtGoal(this, PlayerEntity.class, 6.0F));
		this.goalSelector.addGoal(8, new LookRandomlyGoal(this));
	}
	
	protected void registerAttributes()
	{
		super.registerAttributes();
		this.getAttribute(SharedMonsterAttributes.MAX_HEALTH).setBaseValue(10.0d);
		this.getAttribute(SharedMonsterAttributes.MOVEMENT_SPEED).setBaseValue(5.0d);
	}
}

	public static void registerEntitySpawnEggs(final RegistryEvent.Register<Item> event)
	{
		event.getRegistry().registerAll

		);
	}
	
	public static void registerEntityWorldSpawns()
	{

	}
	
	public static Item registerEntitySpawnEgg(EntityType<?> type, int color1, int color2, String name)
	{
		SpawnEggItem item = new SpawnEggItem(type, color1, color2, new Item.Properties().group(ModItemGroups.RAINBOW_MOD_GROUP));
		item.setRegistryName(new ResourceLocation(Main.MODID, name));
		return item;
	}
	
	public static void registerEntityWorldSpawn(EntityType<?> entity, Biome... biomes)
	{
		for(Biome biome : biomes)
		{
			if(biome != null)
			{
				biome.getSpawns(entity.getClassification()).add(new SpawnListEntry(entity, 20, 1, 10));

Im have troubles here:

package mod.dragonita.fantasymod.client.renders;

import mod.dragonita.fantasymod.entities.UnicornEntity;
import mod.dragonita.fantasymod.init.FantasyModEntities;
import mod.dragonita.fantasymod.init.ModEntities;

import net.minecraft.entity.passive.horse.HorseEntity;
import net.minecraftforge.api.distmarker.Dist;
import net.minecraftforge.api.distmarker.OnlyIn;
import net.minecraftforge.fml.client.registry.RenderingRegistry;

@OnlyIn(Dist.CLIENT)
public class FantasyRenderRegistry
{
	@SuppressWarnings("unchecked")
	public static void registryEntityRenders()
	{
		RenderingRegistry.registerEntityRenderingHandler((EntityType<? extends HorseEntity>) FantasyModEntities.UNICORN_ENTITY, new UnicornEntityRender.RenderFactory()); //Here i have my errors message
	}
}

I am getting the following error message: 

The method registerEntityRenderingHandler(EntityType<T>, IRenderFactory<? super T>) in the type RenderingRegistry is not applicable for the arguments (EntityType<capture#2-of ? extends HorseEntity>, UnicornEntityRender.RenderFactory)

I already say thank you for all your help.

Do not create registry entries in a static initializer. Use the DeferredRegister class.

I am new in Java and Modding. What is a registry entrie?

Why?

The error message says that the arguments you are trying to pass to registerEntityRenderingHandler are not valid. Check the method parameters and their types and make sure your arguments match.

I arleady made this, but i am new and i dont find what i made wrong. Its want a entity type and i have arleady write my entity type, but it have still continue to send me this error message. I tried, but it dont work.

Any implementation of IForgeRegistry (blocks, items, etc). These should be created during the appropiate registry event.

This is basic Java syntax. If you are struggling with this then you need to learn Java before making a mod. This is not a Java forum.

Ok, thanks. What is a EntityType? Is this my Entity or something else? Auf jedenfalls arbeite ich gerade um dieses Problem lösen können.

Should i replace the RenderingRegistry with the DeferredRegister?

 

Ok, I know that I'm annoying you with my questions, and I also tried to look at some vanilla code, but all I need is this: In which folder is the Entity RenderRegistry? I'm looking for a solution to my problem right now, and as it is written in the tips from @DavidM: The best way to learn is to look at the vanilla code. So I've been thinking and want to look at a classic code. I'm just now noticing how many things I have to work on, so I want to finish this topic first and then improve myself, because it must be really annoying to try to help someone who doesn't know anything.

 

 

Thanks for reading it.

EntityType is just that: A type of entity, such as "creeper" or "zombie".

It simply is the Type of my Entity, my Entity in others word. Can i use my Entity like a EntityType?

Edit: I was so stupid, the solution was before my eyes for the whole time. I already made an EntityType, just had to import it.

@diesieben07, i'm sorry, I was just checking to make sure. 

Ok, so if I understood and read well then I should implement the IForgeRegistryEntry in a class. The (hopefully last) question: Where should I implement it, in which class? I don't want to take any risk, but if I have read it then I have to implement it in my entity class. Am I right?

You would know this if you had read the (already linked) documentation:

I read it, only dont have see the difference between client physical side and client logical side.

this is what my IDE shows me (Tried to look at a vanilla code):

@net.minecraftforge.api.distmarker.OnlyIn(value=net.minecraftforge.api.distmarker.Dist.CLIENT)

I know it's exactly the same. But I don't understand that, even with the link you've already given. I just find it hard to understand that, and except for these four differences I don't understand at all. Why do you say I can't do it this way, but the vanilla code does exactly that? Could you explain it to me (And yes, I repeat, I read the link and still don't understand it)?

However the code is not identical of course, some things (like GUIs or world rendering) only exist on the client. These things are marked by forge using @OnlyIn to signify "I only found this in distribution X".

(Similarly some things may only exist in the dedicated server distribution, but is going to be a much, much shorter list that is largely irrelevant for modding).

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.

A more modern name for physical side is "distribution".

 

This is the physical client (client distribution):
image.png.0820c9f02aa62ed957151d303e846c1c.png

When you start a single-player world it starts a logical client and a logical server (the integrated server). The distribution remains client, even for the integrated server. You don't suddenly have a dedicated server running.

When you connect to a server it starts a logical client.

 

This is the physical server (server distribution):

image.png.83f15c573a349cbf20abd8690109f69b.png

It only contains one logical side: The server. The distribution is always server.

 

Well, it definitely exists.

 

@OnlyIn is a forge thing. Vanilla does not have this.

During setup, forge merges the minecraft client jar and the server jar together (the two distributions, see the images above if you don't know the difference) to create one codebase.

However the code is not identical of course, some things (like GUIs or world rendering) only exist on the client. These things are marked by forge using @OnlyIn to signify "I only found this in distribution X".

Wow, thanks for that answer. Now I understand everything except for one point: Why can't I use @OnlyIn and what should I replace it with (the docs is really outdated soon and I don't know what to use now. Strange, when I pressed ctrl + spacebar in the IDE, then normal white comes up with a whole bunch of variables/functions I can use, but I haven't seen any FMLEnvironment.Dist)? If it is, then how should I use it? Usually my IDE tells me, but I don't see anything.

Can you please show your solution or tell me the name of the official java-class, that calls "registerEntityRenderingHandler" to register entity renderers?

I don´t know how to find this file, if i don´t know it´s name..
