[Solved] [1.7.10] Client-Side entity function not being called

[PhantomTiger]

Hello everyone,

I have been working on a mod for a year now and am almost complete, however something about entity coding trips me up, I have my final entity, a hanging entity, almost working, however the client side function needed for the rendering of my entity is not being called and I am not sure how to call it, I have tried just simply naming the function in my class which references the vanilla class and even completely putting the client side function in my class all to no avail. Help to solve what I'm doing wrong is greatly appreciated!

 

Here is my entity class:

 

public class PapPapEntity extends EntityPainting implements IEntityAdditionalSpawnData{

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

public PapPapEntity(World world2, int int1, int int2, int int3, int int4) {
	super(world2, int1, int2, int3, int4);
}

@SideOnly(Side.CLIENT)
public PapPapEntity(World wo, int i, int j, int k, int l, String s){
    super(wo, i, j, k, l);
    
    PapPapEntity.EnumArt[] aenumart = PapPapEntity.EnumArt.values();
    int i1 = aenumart.length;
    
    for (int j1 = 0; j1 < i1; ++j1){
      PapPapEntity.EnumArt enumart = aenumart[j1];
      if (enumart.title.equals(s)){
        this.art = enumart;
        break;
      }
    }
    this.setDirection(l);
}

public void onBroken(Entity entit){
        if (entit instanceof EntityPlayer){
            EntityPlayer entityplayer = (EntityPlayer)entit;

            if (entityplayer.capabilities.isCreativeMode){
                return;
            }
        }

        this.entityDropItem(new ItemStack(TigerItems.PapPap), 0.0F);
    }

@Override
public void writeSpawnData(ByteBuf buffer) {

}

@Override
public void readSpawnData(ByteBuf additionalData) {

}

}

 

 

This is the function in EntityPainting which I am trying to call

 

@SideOnly(Side.CLIENT)
    public EntityPainting(World p_i1601_1_, int p_i1601_2_, int p_i1601_3_, int p_i1601_4_, int p_i1601_5_, String p_i1601_6_)
    {
        this(p_i1601_1_, p_i1601_2_, p_i1601_3_, p_i1601_4_, p_i1601_5_);
        EntityPainting.EnumArt[] aenumart = EntityPainting.EnumArt.values();
        int i1 = aenumart.length;

        for (int j1 = 0; j1 < i1; ++j1)
        {
            EntityPainting.EnumArt enumart = aenumart[j1];

            if (enumart.title.equals(p_i1601_6_))
            {
                this.art = enumart;
                break;
            }
        }

        this.setDirection(p_i1601_5_);
    }

 

 

Thanks!

While I don't know the answer off-hand, I do know that there have been many threads about this exact topic here that you could probably find the answer in if you searched.

 

There is some kind of trick to getting a painting to render correctly that isn't really obvious as it is not handled the same way that most other rendering is in Minecraft.

 

EDIT: Here is a thread with a potential solution.

[PhantomTiger]

Thanks for the reply! But I have spent days combing all the painting rendering related posts and tried at least a hundred things over the past year to still be unable to get it to render. I always try to figure things out myself and hate asking for help but this one problem is too much for me alone. But I do hope whoever knows the solution can help me

 

EDIT: I definitely have spent a lot of time observing that post you suggested, it helped me fix a lot of other problems, but for client side functions I believe changed a bit from 1.7.10 to 1.8, but I will keep looking at what he did

[PhantomTiger]

So I kind of have no clue what I did but the paintings SPAWN now and WITH my texture (kind of how programming works isn't it?), there's just one slight issue left, which I know gottsch has made a post for a while ago however was never solved, but maybe someone can help me figure this out. Whenever I spawn the painting they stay for about 5 seconds before it shift 1/2 block upwards, to just test if this still occurs when the mod is built and in a non-test environment they acted slightly different but still wrong. Small paintings (1x1 and 2x1) still move up a half block (and sometimes jump a full block up but back down to a half block immediately afterward), however larger paintings (i.e. 2x2) just jump up one block and stay stable there. I am not too sure how to debug why this jump occurs. All help is appreciated and kind thanks to all those who helped me get this far!

I hope this also helps anyone else out there struggling to get a custom painting to work in 1.7.10

[PhantomTiger]

So after messing around with the code this morning I finally solved the issue, firstly I @Override the readSpawnData and writeSpawnData functions in my entity class which didn't directly solve the issue however did appear to smooth-en the rendering process. However while combing through the forums again I found a post by diesieben07 and changed my registering function to EntityRegistry.registerModEntity(PapPapEntity.class, "PapPapEntity", 113, MainRegistry.modInstance, 128, Integer.MAX_VALUE, false); and wall-la it works wonderfully, thank you very much diesieben07. And thank you kindly jeffryfisher, jabelar, Izzy Axel, and Abastro for helping me progress to this point in my older posts on older issues with my custom painting.

 

Try using the registering parameters that vanilla uses for Paintings, they work good for my posters:

EntityRegistry.registerModEntity(EntityPoster.class, "poster", 0, this, 160, Integer.MAX_VALUE, false);

 

After a year (I started this mod on April 29, 2015) I can finally clean it up and get this puppy out there, but thank you all for the help, I definitely have a much more hefty knowledge of entity coding now.
