[SOLVED] [1.8] Custom Painting spawned but invisible

[JimiIT92]

As by title, i have a custom Item painting. I do a print in the code to see if spawns the paint and it actually does, also when i break the supporting blocks it drops the item as well, but the painting itself is not rendering in world.

This is my ItemCustomPainting class

package blaze.items;

import blaze.core.BLTabs;
import blaze.entities.EntityPaintingEB;
import net.minecraft.entity.EntityHanging;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.util.BlockPos;
import net.minecraft.util.EnumFacing;
import net.minecraft.world.World;

public class ItemCustomPainting extends Item
{
    private final Class hangingEntityClass;

    public ItemCustomPainting(Class entityClass)
    {
        this.hangingEntityClass = entityClass;
        this.setCreativeTab(BLTabs.tabBlocks);
    }

    /**
     * Called when a Block is right-clicked with this Item
     *  
     * @param pos The block being right-clicked
     * @param side The side being right-clicked
     */
    public boolean onItemUse(ItemStack stack, EntityPlayer playerIn, World worldIn, BlockPos pos, EnumFacing side, float hitX, float hitY, float hitZ)
    {
        if (side == EnumFacing.DOWN)
        {
            return false;
        }
        else if (side == EnumFacing.UP)
        {
            return false;
        }
        else
        {
            BlockPos blockpos1 = pos.offset(side);

            if (!playerIn.canPlayerEdit(blockpos1, side, stack))
            {
                return false;
            }
            else
            {
            	EntityPaintingEB entityhanging = this.createEntity(worldIn, blockpos1, side);

                if (entityhanging != null && entityhanging.onValidSurface())
                {
                    if (!worldIn.isRemote)
                    {
                        worldIn.spawnEntityInWorld(entityhanging);
                        System.out.println("SPAWNED");
                    }

                    --stack.stackSize;
                }

                return true;
            }
        }
    }

    private EntityPaintingEB createEntity(World worldIn, BlockPos pos, EnumFacing clickedSide)
    {
        return new EntityPaintingEB(worldIn, pos, clickedSide);
    }
}

The entity is registered as well and in Client Proxy is binded to it's rendering

So what am i missing? Why this painting is invisible?

[JimiIT92]

up

[JimiIT92]

Ok, so i've change this

painting_eb = new ItemCustomPainting(EntityPaintingEB.class);

with this

painting_eb = new ItemCustomPainting(EntityPainting.class);

and also changed this

private EntityHanging createEntity(World worldIn, BlockPos pos, EnumFacing clickedSide)
    {
        return (EntityHanging)(new EntityPaintingEB(worldIn, pos, clickedSide));
    }

with this

private EntityHanging createEntity(World worldIn, BlockPos pos, EnumFacing clickedSide)
    {
        return (EntityHanging)(new EntityPainting(worldIn, pos, clickedSide));
    }

and everything works fine, so i believe that the problem is with my custom EntityPainting.

 

This is how i register my entity

-> Called from preInit method, before adding the custom painting item
public static EntityPaintingEB painting_eb;
painting_eb = new EntityPaintingEB(null);
-> Called from the init method, before registering the custom painting item
EntityRegistry.registerModEntity(EntityPaintingEB.class, "paintingEB", starting_id, BL.instance, 128, 1, true);

 

So what's wrong with this entity? It's just a copy of the normal EntityPainting, so why it doesn't work?

[JimiIT92]

Nobody? I really really need help with this

[jeffryfisher]

It's near impossible to scan several large java scripts and then notice what's *not* there.

 

Have you set breakpoints in your custom renderer and then run the debugger? Have you searched the log for any registration or rendering errors? Start larding your code with temporary output statements to give yourself more info about what your program is really doing (it might not even be reaching your custom renderer for some reason). Then again, a simple minus sign could be rendering your entire painting bahind the surface of the block it's mounted on 

 

I did a paintings mod in 1.7, but it was over a year ago. I'll be upgrading it to 1.8 soon, so I'll be following this thread and have more to contribute when I get back into it.

[JimiIT92]

I do some debug try. As i said i'm sure the painting is placed and spawned (checked this with a print), also place some breakpoints in rendering class and they are being reached, so the rendering class is called.

Quick update:

I removed this check from my item class

if (!worldIn.isRemote)
{
    worldIn.spawnEntityInWorld(entityhanging);
}
[code]
and replacing it with only this
[code]
worldIn.spawnEntityInWorld(entityhanging);

spawn the painting in the world, but when i break the supporting block it doesn't disappear but it also drop me the painting item

This is the updated code

Another test. As i was suspecting the render methods are never called! I don't know why. Is somehow related to how i register the entities?

I do this

->from the preInit
public static EntityPaintingEB painting_eb;
painting_eb = new EntityPaintingEB(null);
->from the Init
EntityRegistry.registerModEntity(painting_eb, "painting_eb", EntityRegistry.findGlobalUniqueEntityId(), BL.instance, 128, 1, true);

The constructor takes a World argument, wich here i set it to null. I've tried setting it to this

Minecraft.getMinecraft().theWorld

but it doesn't change. Please i really need help with this

[JimiIT92]

up It's almost solved

[SanAndreaP]

Your registerModEntity call is messed up, this is how it's supposed to get called:

https://github.com/SanAndreasP/TurretModRebirth/blob/master/java/de/sanandrew/mods/turretmod/util/TmrEntities.java#L29-L35

 

1. parameter: the class of your entity, not the instance of said class.

2. parameter: the entity registration name

3. parameter: the mod-unique entity ID, beginning with 0. DO NOT use findGlobalUniqueEntityId, ever.

4. parameter: your mod instance

5. parameter: the tracking range. Look at EntityList EntityTracker on what value vanilla paintings use.

6. parameter: the tracking tick rate. Look at EntityList EntityTracker on what value vanilla paintings use.

7. parameter: send velocity updates, for paintings, you don't need to send them, so set it to false.

[JimiIT92]

Ok i'll change it to that

Also, why i should never use the findGlobalUniqueEntityId? I always used that to register mobs and never had problems I forgot to mention that is use it only once, to know "from wich value to start" and then i increment that, is this correct or i should always start with a specific value?

 

[JimiIT92]

Ok, i now have only this

EntityRegistry.registerModEntity(EntityPaintingEB.class, "paintingEB", 0, BL.instance, 160, Integer.MAX_VALUE, false);
//EntityPaintingEB is the entity class
//"paintingEB" is the entity name, is this related to something or can be whatever i want?
//0 is the id (it's totally a random number)
//BL.instance is my mod instance
//160 is the tracking range of vanilla painting
//Integer.MAX_VALUE is the update frequency of vanilla painting

so i removed this

painting_eb = new EntityPaintingEB(null);

But it's still not rendering at all

 

[JimiIT92]

i followed your instructions SanAndreasP but it's still not rendering. I really don't know why this happening

[JimiIT92]

I'm starting to guess that there is no answer to my problem If someone know why my entity is not rendering please tell me, i tried EVERYTHING but nothing worked

[jeffryfisher]

I've started upgrading my own paintings mod to 1.8 (so many red X's!). Though I am still contending with a new pattern of deobfucated names (there have been changes in both directions that have broken my code from 1.7.10), I have found some clues in my old code. One is the declaration of my entity class:

 

public class classAltPainting extends EntityPainting implements IEntityAdditionalSpawnData {

 

The first thing I notice is that I settled (in 1.7) on extending EntityPainting instead of EntityHanging. I recall wrestling with that decision, but I can't for the life of me recall what factor(s) made up my mind.

 

The second thing I notice is the implementation of IEntityAdditionalSpawnData. I think this has something to do with the fact that my painting come in 16 whole collections of paintings, not just one like the vanilla set. However, this aspect of my mod delves into reflection, so I haven't sorted it yet.

 

I think my custom renderer is sorted. I had to parlay my Tesselator into a WorldRenderer

 

It starts like this:

@SideOnly(Side.CLIENT)
public class classRenderAltPainting extends RenderPainting {...

 

And its drawQuads method starts like this:

protected void drawQuads(EntityPainting p, int pxWidth, int pxHeight, int pxOffRight, int pxOffDn) {
    Tessellator tess = Tessellator.getInstance ();
    WorldRenderer wr = tess.getWorldRenderer ();

 

All of the graphics methods (e.g. adding vertexes) are called via the wr; only the "draw" at the end is called via tesselator itself.

 

None of this has been test-run in 1.8 yet because there are still some red X's to iron out. I'll let you know if I make any more discoveries.

Though I am still contending with a new pattern of deobfucated names (there have been changes in both directions that have broken my code from 1.7.10), I have found some clues in my old code. One is the declaration of my entity class:

 

public class classAltPainting extends EntityPainting implements IEntityAdditionalSpawnData {

 

The first thing I notice is that I settled (in 1.7) on extending EntityPainting instead of EntityHanging. I recall wrestling with that decision, but I can't for the life of me recall what factor(s) made up my mind.

 

The second thing I notice is the implementation of IEntityAdditionalSpawnData. I think this has something to do with the fact that my painting come in 16 whole collections of paintings, not just one like the vanilla set. However, this aspect of my mod delves into reflection, so I haven't sorted it yet.

 

I think my custom renderer is sorted. I had to parlay my Tesselator into a WorldRenderer

 

It starts like this:

@SideOnly(Side.CLIENT)
public class classRenderAltPainting extends RenderPainting {...

 

And its drawQuads method starts like this:

protected void drawQuads(EntityPainting p, int pxWidth, int pxHeight, int pxOffRight, int pxOffDn) {
    Tessellator tess = Tessellator.getInstance ();
    WorldRenderer wr = tess.getWorldRenderer ();

 

All of the graphics methods (e.g. adding vertexes) are called via the wr; only the "draw" at the end is called via tesselator itself.

 

None of this has been test-run in 1.8 yet because there are still some red X's to iron out. I'll let you know if I make any more discoveries.

 

Thanks man, can't wait to know if it works If you paste here all your painting related class i'll test by myself (so you can continue updating other stuff)

OH MY GOD! I've just solved this! Or well... the painting finally spawns! Ive just let the EntityClass implements the IEntityAdditionalSpawnData  interface, and then add it's related method and IT WORKED!

So this is now my class for the entity

I've also changed the Item class to this

package blaze.items;

import blaze.entities.EntityPaintingEB;
import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.entity.EntityHanging;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.util.BlockPos;
import net.minecraft.util.EnumFacing;
import net.minecraft.world.World;

public class ItemCustomPainting extends Item
{
    private final Class hangingEntityClass;

    public ItemCustomPainting(Class entityClass)
    {
    	super();
        this.hangingEntityClass = entityClass;
        this.setCreativeTab(CreativeTabs.tabDecorations);
    }

    /**
     * Called when a Block is right-clicked with this Item
     *  
     * @param pos The block being right-clicked
     * @param side The side being right-clicked
     */
    public boolean onItemUse(ItemStack stack, EntityPlayer playerIn, World worldIn, BlockPos pos, EnumFacing side, float hitX, float hitY, float hitZ)
    {
        if (side == EnumFacing.DOWN)
        {
            return false;
        }
        else if (side == EnumFacing.UP)
        {
            return false;
        }
        else
        {
            BlockPos blockpos1 = pos.offset(side);

            if (!playerIn.canPlayerEdit(blockpos1, side, stack))
            {
                return false;
            }
            else
            {
            	EntityHanging entityhanging = this.createHangingEntity(worldIn, blockpos1, side);

                if (entityhanging != null && entityhanging.onValidSurface())
                {
                    if (!worldIn.isRemote)
                    {
                        worldIn.spawnEntityInWorld(entityhanging);
                    }

                    --stack.stackSize;
                }

                return true;
            }
        }
    }

    private EntityHanging createHangingEntity(World worldIn, BlockPos pos, EnumFacing clickedSide)
    {
        return new EntityPaintingEB(worldIn, pos, clickedSide);
    }
}

 

Now, the only issue remained is that if a painting of 32x32 pixels is spawned (for example the wither painting), it will actually spawns 1 block higher than where i clicked. So here is a picture of a 32x32 painting

As you can see rendering is fine but i have clicked with the painting on the block above (so the first log block starting from bottom). It only happens with big painting, if a small painting or a "banner" painting is placed everything works fine Hope to find soon what is the problem and post here the solution. Thanks to all who show me support doing this, probably i will never figured out without you And for who is asking himself, i looked into the AtelierCanvas mod source code on Github

[JimiIT92]

Just fixed that by chaging the two functions above with this

@Override
public void writeSpawnData(ByteBuf buffer) {
	buffer.writeInt(this.art.ordinal());

        buffer.writeInt(this.hangingPosition.getX());       // x
        buffer.writeInt(this.hangingPosition.getY());       // y
        buffer.writeInt(this.hangingPosition.getZ());       // z
        buffer.writeByte(this.getHorizontalFacing().getIndex());
}

@Override
public void readSpawnData(ByteBuf buffer) {
	EntityPaintingEB.EnumArt[] aenumart = EntityPaintingEB.EnumArt.values();
	this.art = aenumart[buffer.readInt()];

        int x = buffer.readInt();
        int y = buffer.readInt();
        int z = buffer.readInt();
        
        BlockPos pos = new BlockPos(x, y, z);
        this.hangingPosition = pos;
        this.func_174859_a(EnumFacing.getFront((buffer.readByte())));
}

 

Finally this problem is solved, thanks to everyone of you!!!! Hope this will help you jeffryfisher in your updating process
