[Tutorial] Creating texture variations for entities (Custom Code) [1.17,1.18, 1.19.2]

Started by tetch_wolf on Sat, 10/02/2021 - 23:59

Before we start the tutorial, some warnings:

-This tutorial was made for versions between 1.17 and 1.19.2, so it not work on older generators like 1.12.2, 1.15 or 1.16

-This tutorial doesn't work with layers because mcreator doesn't support the use of variables in the layer method

-A big thank you to my friend Nate (NatePlays95#4509) for helping me with this tutorial, without him I wouldn't have been able to.

Hello!

What's up? I hope well

If you are here, it means that you want to create texture variations for your entities, but without having to create other entities with other textures.

in this detailed tutorial, you'll learn how to create texture variations to how to use them in procedures

Let's go!

Part 1: Creating texture variations

First of all and most obviously, lock your entity code

Lock the Code

Now, we'll enter our entity code (not the render) and start injecting our magic mix

We will go where our entity is extended (monster entity, creature entity, tameable entity, etc.), and we will register a data entrie

Code

Let's record the following data entrie:

public static final EntityDataAccessor<Integer> VariantData = SynchedEntityData.defineId(CustomEntityEntity.class, EntityDataSerializers.INT);

In the end, the code should look like this:

code

you can register different entries with different names, but in this case, we use the name "VariantData"

after that, we will go to some instance of the entity, and we will finish registering our entrie

in my case, I decided to register at the end of the code

code

two spaces after the last "{"

so paste the following code:

	
@Override
	protected void defineSynchedData() {
		super.defineSynchedData();
		this.entityData.define(VariantData, 0);
	}

	public void setVariantData(int varIn) {
		this.entityData.set(VariantData, varIn);
	}

	public int getVariantData() {
		return this.entityData.get(VariantData);
	}

	public void addAdditionalSaveData(CompoundTag compound) {
		super.addAdditionalSaveData(compound);
		compound.putInt("VariantData", this.getVariantData());
	}

	public void readAdditionalSaveData(CompoundTag compound) {
		super.readAdditionalSaveData(compound);
		this.setVariantData(compound.getInt("VariantData"));
	}

Okay, we finished registering our variable, an addendum, to register other variables, it is necessary another method, I will bring it in a future part 2 of this tutorial

In the end, the code should look like this:

code

Click ctrl+w to organize the imports, and then go to import

import net.minecraft.server.commands.data.EntityDataAccessor;

and replace it with

import net.minecraft.network.syncher.EntityDataAccessor;

wrong import

right import

now, press ctrl+w again and save your entity code.

Now, we'll edit the rendering

render

we'll go where the entity's texture is selected, and then we'll edit that part

ResourceLocation

Then replace

return new ResourceLocation("yourmodid:textures/your_texture.png")

with:

[YourEntityName]Entity _variant = (YourEntityNameEntity) entity;
                        return new ResourceLocation("modid:textures/yourentitytexture_" + String.valueOf(_variant.getVariantData()) + ".png");

in my case, it looked like this:

New Resource Location

save your entity's code, and now we'll create a procedure to select the entity's texture

Create a procedure assigned to the "On Initial Entity Spawn" trigger

trigger

create a local variable in the procedure with the same name registered in the entity code

Procedure

first code snippet:

((YourEntityEntity) entity).getVariantData()

second code snippet:

((YourEntityEntity) entity).setVariantData((int)VariantData);

the number [60] in the procedure represents the amount of texture variations that the entity has

Save the procedure, and now we go to the final part of the tutorial

rename your textures so they look like this:

textures

zoi_ruby_1
zoi_ruby_2
etc..

thus, if the generated id is 2, the selected texture will be "zoi_ruby_2.png"

basically, this part of the procedure is responsible for generating an id, and each id is a texture

procedure

also

zoi_ruby_0= base texture

texture 0 will never be selected, so make 1 equal to 0

Let's test it in the game:
Ruby

That's it, thanks for reading this far, I hope I helped you :>

Is this confirmed to be working in 1.17 version, Im getting build errors?

These are the errors I'm recieving back, I think it has to do with the local variable but im not sure. If anyone could help it would be much appreciated.

Could you make a video showcasing this in more detail, and a clear walkthrough?

Does this work for blocks?

Jump to top Permalink

@Ali107 - Blocks use Blockstates, so it's kinda different thing to work on.

As for tutorial - big thank you for creator, this may be extremely helpful for my mod I'm working on right now ^^

Where can I find Set Local: Variant? I can't find it anywhere, and i've looked.

is it posible to do the same but with the glow texture?

Hey, thank you so so much for this tutorial!

I just got this to run on a workspace running MCreator 2022.3 with the earliest iteration of Nerdy's Geckolib plugin for 1.19.2.

I don't know if anyone has tried this since, but in the entity code I had to delete/put in "**/" brackets the section for adding data for the custom inventory like this:


/**
    @Override

    public void addAdditionalSaveData(CompoundTag compound) {

        super.addAdditionalSaveData(compound);

        compound.put("InventoryCustom", inventory.serializeNBT());

    }



    @Override

    public void readAdditionalSaveData(CompoundTag compound) {

        super.readAdditionalSaveData(compound);

        Tag inventoryCustom = compound.get("InventoryCustom");

        if (inventoryCustom instanceof CompoundTag inventoryTag)

            inventory.deserializeNBT(inventoryTag);

    }


**/

otherwise I would get an error complaining that "addAdditionalSaveData" and "readAdditionalSaveData" (which is added for "VariantData") was already in use.

Will disabling this section about the inventory break anything? My entity has a fuel system that still works, so the custom inventory was not affected by this.

Also: I still get broken purple textures... double checked the texture's directories but it didn't change anything.

Should I mark this down as finnicky because of the GecoLib plugin and wait until something similar is introduced in an official MCreator build?

And another question:

why include "zoi" in the naming, like

"zoi_ruby_1
zoi_ruby_2
etc.."

Thank you :)

Wait, how i can add it to Vanilla mobs, like a cow, pig and chicken? Now mine.
