Hello,

I was wondering how could I create a field around a new entity I called "Cubos" (it looks like a cube walking with two wooden legs. I know that the charged creeper (or "Wither" when it has only half his health points left) uses the file CreeperPowerLayer extending EnergySwirlLayer.

Here is the file I created "CubosPowerLayer" :

package fr.vat1n.vatmod.client.renderer.layers;

import fr.vat1n.vatmod.client.renderer.model.CubosModel;
import fr.vat1n.vatmod.entity.common.Cubos;
import net.minecraft.client.model.EntityModel;
import net.minecraft.client.model.geom.EntityModelSet;
import net.minecraft.client.model.geom.ModelLayers;
import net.minecraft.client.renderer.entity.RenderLayerParent;
import net.minecraft.client.renderer.entity.layers.EnergySwirlLayer;
import net.minecraft.resources.ResourceLocation;


public class CubosPowerLayer extends EnergySwirlLayer<Cubos, CubosModel<Cubos>> {
    private static final ResourceLocation POWER_LOCATION = new ResourceLocation("textures/entity/creeper/creeper_armor.png");
    private final CubosModel<Cubos> model;

    public CubosPowerLayer(RenderLayerParent<Cubos, CubosModel<Cubos>> renderLayerParent, EntityModelSet entityModelSet) {
        super(renderLayerParent);
        this.model = new CubosModel<>(entityModelSet.bakeLayer(ModelLayers.CREEPER_ARMOR));
    }

    protected float xOffset(float xOffset) {
        return xOffset * 0.01F;
    }

    protected ResourceLocation getTextureLocation() {
        return POWER_LOCATION;
    }

    protected EntityModel<Cubos> model() {
        return this.model;
    }
}

As you can see, in the constructor, I use the bakeLayer method for the CREEPER_ARMOR since I don't know how and where to create the same for the cubos.

 

And here is the CubosRenderer :

package fr.vat1n.vatmod.client.renderer;

import fr.vat1n.vatmod.VatMod;
import fr.vat1n.vatmod.client.renderer.layers.CubosPowerLayer;
import fr.vat1n.vatmod.client.renderer.model.CubosModel;
import fr.vat1n.vatmod.entity.common.Cubos;
import net.minecraft.client.renderer.entity.EntityRendererProvider;
import net.minecraft.client.renderer.entity.MobRenderer;
import net.minecraft.resources.ResourceLocation;


public class CubosRenderer extends MobRenderer<Cubos, CubosModel<Cubos>> {
    private static final ResourceLocation TEXTURE = new ResourceLocation(VatMod.MOD_ID, "textures/entities/cubos.png");


    public CubosRenderer(EntityRendererProvider.Context context) {
        super(context, new CubosModel<>(context.bakeLayer(CubosModel.LAYER_LOCATION)), 0.5F);
        this.addLayer(new CubosPowerLayer(this, context.getModelSet()));
    }

    @Override
    public ResourceLocation getTextureLocation(Cubos pEntity) {
        return TEXTURE;
    }
}

Finally, here is the CubosModel :

package fr.vat1n.vatmod.client.renderer.model;

import com.google.common.collect.ImmutableList;
import com.mojang.blaze3d.vertex.PoseStack;
import com.mojang.blaze3d.vertex.VertexConsumer;
import fr.vat1n.vatmod.VatMod;
import fr.vat1n.vatmod.entity.common.Cubos;
import net.minecraft.client.model.AgeableListModel;
import net.minecraft.client.model.geom.ModelLayerLocation;
import net.minecraft.client.model.geom.ModelPart;
import net.minecraft.client.model.geom.PartPose;
import net.minecraft.client.model.geom.builders.*;
import net.minecraft.resources.ResourceLocation;
import net.minecraft.util.Mth;


public class CubosModel<Type extends Cubos> extends AgeableListModel<Type> {
  
	public static final ModelLayerLocation LAYER_LOCATION = new ModelLayerLocation(new ResourceLocation(VatMod.MOD_ID, "cubos"), "main");
	private final ModelPart legL;
	private final ModelPart legR;
	private final ModelPart head;
	private final ModelPart root;

	public CubosModel(ModelPart root) {
		this.root = root;
		this.legL = root.getChild("legL");
		this.legR = root.getChild("legR");
		this.head = root.getChild("head");
	}

	public static LayerDefinition createBodyLayer() {
		MeshDefinition meshdefinition = new MeshDefinition();
		PartDefinition partdefinition = meshdefinition.getRoot();
		partdefinition.addOrReplaceChild("head", CubeListBuilder.create().texOffs(0, 0).addBox(-6.0F, -6.0F, -6.0F, 12.0F, 12.0F, 12.0F, new CubeDeformation(0.0F)), PartPose.offset(0.0F, 16.0F, 0.0F));
		partdefinition.addOrReplaceChild("legL", CubeListBuilder.create().texOffs(0, 24).addBox(6.0F, 0.0F, -1.0F, 2.0F, 9.0F, 2.0F, new CubeDeformation(0.0F)), PartPose.offset(0.0F, 15.0F, 0.0F));
		partdefinition.addOrReplaceChild("legR", CubeListBuilder.create().texOffs(8, 24).addBox(-8.0F, 0.0F, -1.0F, 2.0F, 9.0F, 2.0F, new CubeDeformation(0.0F)), PartPose.offset(0.0F, 15.0F, 0.0F));
		return LayerDefinition.create(meshdefinition, 64, 64);
	}

	@Override
	public void setupAnim(Type entity, float limbSwing, float limbSwingAmount, float ageInTicks, float netHeadYaw, float headPitch) {
		this.head.xRot = headPitch * ((float)Math.PI / 180F);
		this.legR.xRot = Mth.cos(limbSwing * 0.6662F) * 1.4F * limbSwingAmount;
		this.legL.xRot = Mth.cos(limbSwing * 0.6662F + (float)Math.PI) * 1.4F * limbSwingAmount;
	}

	@Override
	public void renderToBuffer(PoseStack poseStack, VertexConsumer vertexConsumer, int packedLight, int packedOverlay, float red, float green, float blue, float alpha) {
		this.root.render(poseStack, vertexConsumer, packedLight, packedOverlay, red, green, blue, alpha);
	}

	@Override
	protected Iterable<ModelPart> headParts() {
		return ImmutableList.of(this.head);
	}

	@Override
	protected Iterable<ModelPart> bodyParts() {
		return null;
	}
}

My problem is that the game can't find the "legL" part in the CubosModel : "Caused by: java.util.NoSuchElementException: Can't find part legL"

However, when I delete the line "this.addLayer(new CubosPowerLayer(this, context.getModelSet()));" in the CubosRenderer constructor, the problem disappears. Perhaps the issue comes from the fact I chose the CREEPER_ARMOR which isn't suitable.

I have checked the ModelLayers and LayerDefinitions which contain CREEPER_ARMOR but I can't solve the issue
