It looks like something related to render, so this is the rendering class

package hl.entities.renderer;

import org.lwjgl.opengl.GL11;

import hl.entities.EntityBee;
import hl.models.ModelBee;
import net.minecraft.client.renderer.entity.RenderLiving;
import net.minecraft.client.renderer.entity.RenderManager;
import net.minecraft.entity.Entity;
import net.minecraft.entity.EntityLivingBase;
import net.minecraft.util.ResourceLocation;
import net.minecraftforge.fml.relauncher.Side;
import net.minecraftforge.fml.relauncher.SideOnly;

public class RenderBee extends RenderLiving {

protected ModelBee model;
public static final ResourceLocation beeTexture = new ResourceLocation("hl:textures/mobs/bee.png");
private float scale;


public RenderBee(RenderManager mgr, ModelBee par1ModelBase, float par2, float d)
{
	super(mgr, par1ModelBase, par2);
	model=((ModelBee)mainModel);
	this.scale = d;
}

protected void preRenderScale(EntityBee par1EntityBee, float par2)
{
	GL11.glScalef(this.scale, this.scale, this.scale);
}
protected void preRenderCallback(EntityLivingBase par1EntityLivingBase, float par2)
{
	this.preRenderScale((EntityBee)par1EntityLivingBase, par2);
}
@Override
protected ResourceLocation getEntityTexture(Entity entity) 
{
	return beeTexture;
}

@Override
public void doRender(Entity entity, double d0, double d1, double d2, float f, float f1) {
	renderBee((EntityBee)entity, d0, d1, d2, f, f1);
}

public void doRenderLiving(Entity par1EntityLiving, double par2, double par4, double par6, float par8, float par9)
{
	renderBee((EntityBee)par1EntityLiving, par2, par4, par6, par8, par9);
}

private void renderBee(EntityBee entity, double par2, double par4, double par6, float par8, float par9) 
{
	super.doRender(entity, par2, par4, par6, par8, par9);
}

}

The entity is registered in the preInit method by doing this

EntityHandler.registerMonsters(EntityBee.class, "GiantBee", 0xDDAB22, 0x000000F);

In EntityHandler i do this

int entityId = EntityRegistry.findGlobalUniqueEntityId();

EntityRegistry.registerGlobalEntityID(entityClass, name, entityId);
EntityRegistry.addSpawn(entityClass, 15, 2, 4, EnumCreatureType.AMBIENT);
EntityList.entityEggs.put(Integer.valueOf(entityId), new EntityList.EntityEggInfo(entityId, mainColor, subColor));

And then in ClientProxy i do this

RenderingRegistry.registerEntityRenderingHandler(EntityBee.class, new RenderBee(Minecraft.getMinecraft().getRenderManager(), new ModelBee(), 0.3F, 0.5F));

wich is called from the init method So why it crashes on spawn?

I don't know In the client everything works fine. By the way here is the model and the entity class, just in case is needed

Model class


package hl.models;

import net.minecraft.client.model.ModelBase;
import net.minecraft.client.model.ModelRenderer;
import net.minecraft.entity.Entity;
import net.minecraft.util.MathHelper;

public class ModelBee extends ModelBase
{
ModelRenderer head;
ModelRenderer rightantenna;
ModelRenderer leftantenna;
ModelRenderer mouth;
ModelRenderer body;
ModelRenderer butt;
ModelRenderer stinger;
ModelRenderer legs;
ModelRenderer leftwing;
ModelRenderer rightwing;

public ModelBee()
{
	textureWidth = 64;
	textureHeight = 32;

	head = new ModelRenderer(this, 0, 0);
	head.addBox(-2.5F, -9F, -4F, 5, 5, 4);
	head.setRotationPoint(0F, 0F, -2F);
	head.setTextureSize(64, 32);
	head.mirror = true;
	setRotation(head, 0F, 0F, 0F);

if i spawn an entity in a server...
java.lang.NullPointerException: Rendering entity in world

Server + Renderer = crash.

Renderers don't belong on servers

Also:

WARNING: coremods are present:
NowWithRendering (hopperducts-mc1.8-1.4.5.jar)

Contact their authors BEFORE contacting forge

What did the core mod authors say about the renderer crash?

JimiIT92 · December 22, 2015

It crashes also without the core mod So basically i should register the rendering only client side? And in that case how?

EDIT: it crashes also client side. The line 45 and 55 refers to the doRender and renderBee functions in the rendering class

JimiIT92 · December 22, 2015

Maybe not I had that functions just because is a port from 1.7.10, and i'm not really expert with rendering in general So i'll try removing them and see if it works

JimiIT92 · December 22, 2015

Removed that functions, still crash My class now looks like this

package hl.entities.renderer;

import org.lwjgl.opengl.GL11;

import hl.entities.EntityBee;
import hl.models.ModelBee;
import net.minecraft.client.renderer.entity.RenderLiving;
import net.minecraft.client.renderer.entity.RenderManager;
import net.minecraft.entity.Entity;
import net.minecraft.entity.EntityLivingBase;
import net.minecraft.util.ResourceLocation;
import net.minecraftforge.fml.relauncher.Side;
import net.minecraftforge.fml.relauncher.SideOnly;

public class RenderBee extends RenderLiving {

private float scale;


public RenderBee(RenderManager mgr, ModelBee par1ModelBase, float par2, float d)
{
	super(mgr, par1ModelBase, par2);
	this.scale = d;
}

protected void preRenderScale(EntityBee par1EntityBee, float par2)
{
	GL11.glScalef(this.scale, this.scale, this.scale);
}
protected void preRenderCallback(EntityLivingBase par1EntityLivingBase, float par2)
{
	this.preRenderScale((EntityBee)par1EntityLivingBase, par2);
}
@Override
protected ResourceLocation getEntityTexture(Entity entity) 
{
	return new ResourceLocation("hl:textures/mobs/bee.png");
}

}

JimiIT92 · December 23, 2015

So it turns out that the problem was that i registered the rendering in the preInit method instead of the init Thanks to all who tried to help me
