[1.7.10] [Not Resolved] Entity Rendering Not Working.

Posted December 3, 201410 yr

So I've made an entity, but the problem is when I spawn it with a spawn egg it doesn't render. Here is my code:

Entity:

public class ArcanePowerMatrix 
			extends EntityLiving{



public ArcanePowerMatrix(World world) {
	super(world);
}

@Override
protected void entityInit() {

}

@Override
public void readEntityFromNBT(NBTTagCompound tags) {

}

@Override
public void writeEntityToNBT(NBTTagCompound tags) {

}
}

Model:

public class ModelPowerMatrix extends ModelBase{
  //fields
    ModelRenderer Base;
    ModelRenderer MainCube;
    ModelRenderer littleCube;
    ModelRenderer littleCube2;
    ModelRenderer littleCube3;
    ModelRenderer littleCube4;
  
  public ModelPowerMatrix()
  {
    textureWidth = 128;
    textureHeight = 64;
    
      Base = new ModelRenderer(this, 0, 32);
      Base.addBox(-5F, 0F, -5F, 10, 1, 10);
      Base.setRotationPoint(0F, 23F, 0F);
      Base.setTextureSize(64, 32);
      Base.mirror = true;
      setRotation(Base, 0F, 0F, 0F);
      MainCube = new ModelRenderer(this, 0, 0);
      MainCube.addBox(-6F, -6F, -6F, 12, 12, 12);
      MainCube.setRotationPoint(0F, 11F, 0F);
      MainCube.setTextureSize(64, 32);
      MainCube.mirror = true;
      setRotation(MainCube, -0.7853982F, 0F, -0.7853982F);
      littleCube = new ModelRenderer(this, 50, 0);
      littleCube.addBox(-2F, -2F, -2F, 4, 4, 4);
      littleCube.setRotationPoint(5.5F, 5.5F, -11.5F);
      littleCube.setTextureSize(64, 32);
      littleCube.mirror = true;
      setRotation(littleCube, -0.7853982F, 0F, -0.7853982F);
      littleCube2 = new ModelRenderer(this, 50, 0);
      littleCube2.addBox(-2F, -2F, -2F, 4, 4, 4);
      littleCube2.setRotationPoint(5.5F, 5.5F, 11.5F);
      littleCube2.setTextureSize(64, 32);
      littleCube2.mirror = true;
      setRotation(littleCube2, -0.7853982F, 0F, -0.7853982F);
      littleCube3 = new ModelRenderer(this, 50, 0);
      littleCube3.addBox(-2F, -2F, -2F, 4, 4, 4);
      littleCube3.setRotationPoint(-2F, -3F, 0F);
      littleCube3.setTextureSize(64, 32);
      littleCube3.mirror = true;
      setRotation(littleCube3, -0.7853982F, 0F, -0.7853982F);
      littleCube4 = new ModelRenderer(this, 50, 0);
      littleCube4.addBox(-2F, -2F, -2F, 4, 4, 4);
      littleCube4.setRotationPoint(14F, 13F, 0F);
      littleCube4.setTextureSize(64, 32);
      littleCube4.mirror = true;
      setRotation(littleCube4, -0.7853982F, 0F, -0.7853982F);
  }
  
  public void render(Entity entity, float f, float f1, float f2, float f3, float f4, float f5)
  {
    super.render(entity, f, f1, f2, f3, f4, f5);
    setRotationAngles(f, f1, f2, f3, f4, f5, entity);
    Base.render(f5);
    MainCube.render(f5);
    littleCube.render(f5);
    littleCube2.render(f5);
    littleCube3.render(f5);
    littleCube4.render(f5);
  }
  
  private void setRotation(ModelRenderer model, float x, float y, float z)
  {
    model.rotateAngleX = x;
    model.rotateAngleY = y;
    model.rotateAngleZ = z;
  }
  
  public void setRotationAngles(float f, float f1, float f2, float f3, float f4, float f5, Entity entity)
  {
    super.setRotationAngles(f, f1, f2, f3, f4, f5, entity);
  }
}

Renderer:

@SideOnly(Side.CLIENT)
public class RenderPowerMatrix
			extends RenderLiving{

public RenderPowerMatrix(ModelBase modelBase, float shadowSize) {
	super(modelBase, shadowSize);
}

@Override
protected ResourceLocation getEntityTexture(Entity var1) {
	return new ResourceLocation("wizardry", "/textures/entities/PowerMatrix.png");
}
}

My entity is registered like this:

registerEntity(ArcanePowerMatrix.class, "powerMatrix", 000, 000);

registerEntity is like this:

public void registerEntity(Class<? extends Entity> entityClass, String entityName, int bkEggColor, int fgEggColor) {
    	int id = EntityRegistry.findGlobalUniqueEntityId();
    	EntityRegistry.registerGlobalEntityID(entityClass, entityName, id);
    	EntityList.entityEggs.put(Integer.valueOf(id), new EntityList.EntityEggInfo(id, bkEggColor, fgEggColor));
    }

In ClientProxy my renderer is registered like this:

RenderingRegistry.registerEntityRenderingHandler(ArcanePowerMatrix.class, new RenderPowerMatrix(new ModelPowerMatrix(), 0F));

Are you calling the method which holds

RenderingRegistry.registerEntityRenderingHandler(ArcanePowerMatrix.class, new RenderPowerMatrix(new ModelPowerMatrix(), 0F));

in your main class?

Quote

December 4, 201410 yr

No, I'm calling it in my ClientProxy.

Oh sorry, I was tired when I read that, yes I'm calling that method in my main class (not ClientProxy, that wouldn't have worked, sorry for the miss-understanding).

Add an println to the onUpdate method to make sure it is spawning right (make sure to call super!). Can we see spawning code?

Quote

December 5, 201410 yr

Well... I guess some people are as stumped as me.

Does the game crash when you try (Post Error)? Or does it just not render at all?

What onUpdate method? I try to add that. Also I don't have spawning code, I just register the entity and it does that on it's own.

Well... I guess some people are as stumped as me.

It just doesn't render at all, either that or it doesn't spawn.

Now that I look at it, it gives me this in the console when I use the spawn egg:

Weird a NullPointerException at the end, easy to fix. But it says it can't find the health info, even EASIER to fix well i'll try to fix it then. If I don't i'll reply again.

You need to call super.entityInit in your overridden method.

Still not working.

The onUpdate method is called each tick (look at Entity class). The println was to check it was spawning correctly, you might want to make it print (this.worldObj.isRemote + ", " + this) to see the entity and which world it is in. Give us what that outputs and updated code when you implement it.

I place this code (this is how I debug):

Wizardry.log.debug(this.worldObj.isRemote + ", " + this);

where you advised me to put it and it printed absolutely nothing when I spawned the entity. Thoughts?

Well here is the updated code:

package com.awsp8.wizardry.Entities;

import com.awsp8.wizardry.Wizardry;

import sun.misc.SharedSecrets;
import net.minecraft.entity.EntityLiving;
import net.minecraft.entity.SharedMonsterAttributes;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.world.World;

public class ArcanePowerMatrix 
			extends EntityLiving{



public ArcanePowerMatrix(World world) {
	super(world);
}

@Override
public void entityInit(){
	super.entityInit();
}

@Override
public void onUpdate(){
	super.onUpdate();

	Wizardry.log.debug(this.worldObj.isRemote + ", " + this);
}

@Override
public void applyEntityAttributes(){
        super.applyEntityAttributes();
    }

@Override
public boolean canDespawn(){
	return false;
}

@Override
public boolean canBePushed(){
	return false;
}
}

And I have noticed that the exception is gone, but it still doesn't spawn. Now I'm actually not sure now whether it's a rendering problem or a spawning problem (considering it doesn't print anything).

I use this method to create a spawn egg for it:

public void registerEntity(Class<? extends Entity> entityClass, String entityName, int bkEggColor, int fgEggColor) {
    	int id = EntityRegistry.findGlobalUniqueEntityId();
    	EntityRegistry.registerGlobalEntityID(entityClass, entityName, id);
    	EntityList.entityEggs.put(Integer.valueOf(id), new EntityList.EntityEggInfo(id, bkEggColor, fgEggColor));
    }

But I don't understand why it's not working because all my other entities spawn ok, but this one doesn't spawn. I have no idea why, they are all registered the same way.

December 6, 201410 yr

How many entities do you have?

Five, counting the one that isn't working.

Quote

December 6, 201410 yr

Then I have no clue. Setup a proper git repo so that I can easily check out your code. No, a zip download does not work.

I have a git repos:

My entity code:

https://github.com/AwesomeSpider/Wizardry/blob/master/src/main/java/com/awsp8/wizardry/Entities/ArcanePowerMatrix.java

My entity model code:

https://github.com/AwesomeSpider/Wizardry/blob/master/src/main/java/com/awsp8/wizardry/entity/model/ModelPowerMatrix.java

My entity rendering code:

https://github.com/AwesomeSpider/Wizardry/blob/master/src/main/java/com/awsp8/wizardry/entity/render/RenderPowerMatrix.java

Hope you can help, if not it's fine I can always remove the entity.

December 6, 201410 yr

First of all, fix that repo. All that crap should not be in there, only src, gradle, the gradlew files and build.gradle.

Allright, I will.

Ok, I cleaned it up as best I could, it took a while to figure out how to use .gitignore files.

Quote

December 6, 201410 yr

a) your .gitignore did not fix it.

b) Somehow your entity *is* spawned but immediately dies or something. Not sure why.

Oh I see, maybe it has no health, would that make it die immediately?

Quote

December 6, 201410 yr

well, that would at least make
setDead
be called on the entity, but that is not the case either. it just seems as if the entity instance just vanishes.

Weird... I just remembered this has happened to me before with another entity. If I'm remembering correctly I couldn't fix it and ended up having to delete the entity. I had no idea what caused it, this is REALLY weird. I'll do more research, wish me luck.

Quote

December 6, 201410 yr

Repo looks good, but I am still kinda stumped as to why that happens.

Oh and by the way, your code is a mess. Literally every class has loads and loads of warnings everywhere.

Wait I didn't see this reply sorry. Lol, what kind of warnings? My eclipse doesn't show any warnings.

Quote

December 6, 201410 yr

Well, that is because in the default eclipse workspace that comes with forge most warnings are turned off.

Oh lol I didn't know that.

exit code 1

I'm having problems loading some mods, once it launches it crashes and says exit code. This doesn't happen on an older mod and I've tried a couple things to fix this however, nothing seems to fix. Any advice?

New Forum Design/Update: Issues and Suggestions

Hiho,

first of all I want to say that the new forum design looks really good.

However, there are currently two issues:

In the "Unread" section, the "Mark all as Read" feature seems to be missing - or am I just overlooking it somewhere?
Some threads don’t automatically get marked as read when you open them. So the post still shows up in "Unread," even though you’ve already viewed it.
Example Thread: https://forums.minecraftforge.net/topic/159415-cannot-find-client-log-entries/

Then I have a smaller suggestion, referring to the Text Editor:

It is possible to move out the "Inline Code"-Feature from the "More Formatting Options" and add it directly to the Text Editor Tool Bar?
Same for "Quote"-Feature inside the Create Section

These two features are used quite often (at least by me) - as far as I remember, they were also available in the old forum design.
