Creating new XP orb

Hello, I'm trying to create a new type of xp orb. To do this I've basically copied the original xp orb, and added a few modifications. The entity works fine as I can see its effects, however, I cannot get it to render at all. I've tried adding this to my initialization method:

EntityRegistry.registerGlobalEntityID(MyNewOrb.class, "myNewOrb", EntityRegistry.findGlobalUniqueEntityId());

 

and then this at the same point, only in my ClientProxy:

RenderingRegistry.registerEntityRenderingHandler(MyNewOrb.class, new RenderMyNewOrb());

 

and finally, here is my code for rendering it:

@SideOnly(Side.CLIENT)
public class RenderMyNewOrb extends Render
{
    private static final ResourceLocation field_110785_a = new ResourceLocation("textures/entity/experience_orb.png");

    public RenderMyNewOrb()
    {
        this.shadowSize = 0.15F;
        this.shadowOpaque = 0.75F;
    }

    /**
     * Renders the Orb.
     */
    public void renderTheOrb(EntityMyNewOrb par1EntityMyNewOrb, double par2, double par4, double par6, float par8, float par9)
    {
        GL11.glPushMatrix();
        GL11.glTranslatef((float)par2, (float)par4, (float)par6);
        this.func_110777_b(par1EntityMyNewOrb);
        int i = par1EntityMyNewOrb.getTextureByValue();
        float f2 = (float)(i % 4 * 16 + 0) / 64.0F;
        float f3 = (float)(i % 4 * 16 + 16) / 64.0F;
        float f4 = (float)(i / 4 * 16 + 0) / 64.0F;
        float f5 = (float)(i / 4 * 16 + 16) / 64.0F;
        float f6 = 1.0F;
        float f7 = 0.5F;
        float f8 = 0.25F;
        int j = par1EntityMyNewOrb.getBrightnessForRender(par9);
        int k = j % 65536;
        int l = j / 65536;
        OpenGlHelper.setLightmapTextureCoords(OpenGlHelper.lightmapTexUnit, (float)k / 1.0F, (float)l / 1.0F);
        GL11.glColor4f(1.0F, 1.0F, 1.0F, 1.0F);
        float f9 = 255.0F;
        int i1 = (int)f9;
        int k1 = 0x00BC5E5E;
        if (par1EntityMyNewOrb.isBlue)
        	k1 = 0x0083E3E3;
        GL11.glRotatef(180.0F - this.renderManager.playerViewY, 0.0F, 1.0F, 0.0F);
        GL11.glRotatef(-this.renderManager.playerViewX, 1.0F, 0.0F, 0.0F);
        float f11 = 0.3F;
        GL11.glScalef(f11, f11, f11);
        Tessellator tessellator = Tessellator.instance;
        tessellator.startDrawingQuads();
        tessellator.setColorRGBA_I(k1, 128);
        tessellator.setNormal(0.0F, 1.0F, 0.0F);
        tessellator.addVertexWithUV((double)(0.0F - f7), (double)(0.0F - f8), 0.0D, (double)f2, (double)f5);
        tessellator.addVertexWithUV((double)(f6 - f7), (double)(0.0F - f8), 0.0D, (double)f3, (double)f5);
        tessellator.addVertexWithUV((double)(f6 - f7), (double)(1.0F - f8), 0.0D, (double)f3, (double)f4);
        tessellator.addVertexWithUV((double)(0.0F - f7), (double)(1.0F - f8), 0.0D, (double)f2, (double)f4);
        tessellator.draw();
        GL11.glDisable(GL11.GL_BLEND);
        GL11.glDisable(GL12.GL_RESCALE_NORMAL);
        GL11.glPopMatrix();
    }

    protected ResourceLocation func_110784_a(EntityMyNewOrb par1EntityMyNewOrb)
    {
        return field_110785_a;
    }

    protected ResourceLocation func_110775_a(Entity par1Entity)
    {
        return this.func_110784_a((EntityMyNewOrb)par1Entity);
    }

    /**
     * Actually renders the given argument. This is a synthetic bridge method, always casting down its argument and then
     * handing it off to a worker function which does the actual work. In all probabilty, the class Render is generic
     * (Render<T extends Entity) and this method has signature public void doRender(T entity, double d, double d1,
     * double d2, float f, float f1). But JAD is pre 1.5 so doesn't do that.
     */
    public void doRender(Entity par1Entity, double par2, double par4, double par6, float par8, float par9)
    {
        this.renderTheOrb((EntityMyNewOrb)par1Entity, par2, par4, par6, par8, par9);
    }
}

 

The only thing changed is the colour section, which may be wrong, but I'm not the best at bitwise logic.

Updated renderer to not use bitwise logic, still no orbs are rendered.

Use EntityRegistry.registerModEntity(args);

and don't use findGlobalUniqueEntityId().

 

And do

private static final ResourceLocation orbTexture = new ResourceLocation("textures/entity/experience_orb.png");

    public RenderMyNewOrb()
    {
        this.shadowSize = 0.15F;
        this.shadowOpaque = 0.75F;
    }

    /**
     * Renders the Orb.
     */
    public void renderTheOrb(EntityMyNewOrb par1EntityMyNewOrb, double par2, double par4, double par6, float par8, float par9)
    {
        GL11.glPushMatrix();
        GL11.glTranslatef((float)par2, (float)par4, (float)par6);
        this.func_110777_b(par1EntityMyNewOrb);
        int i = par1EntityMyNewOrb.getTextureByValue();
        float f2 = (float)(i % 4 * 16 + 0) / 64.0F;
        float f3 = (float)(i % 4 * 16 + 16) / 64.0F;
        float f4 = (float)(i / 4 * 16 + 0) / 64.0F;
        float f5 = (float)(i / 4 * 16 + 16) / 64.0F;
        float f6 = 1.0F;
        float f7 = 0.5F;
        float f8 = 0.25F;
        int j = par1EntityMyNewOrb.getBrightnessForRender(par9);
        int k = j % 65536;
        int l = j / 65536;

        Tessellator tessellator = Tessellator.instance;
        tessellator.startDrawingQuads();
        
        int r = 188;
        int g = 94;
        int b = 94;
        
        if (par1EntityMyNewOrb.isLight) {
        	r = 131;
        	g = 227;
        	b = 227;
        }
        
        tessellator.setColorRGBA(r,g,b, 128);
        tessellator.setNormal(0.0F, 1.0F, 0.0F);
        tessellator.addVertexWithUV((double)(0.0F - f7), (double)(0.0F - f8), 0.0D, (double)f2, (double)f5);

    }

    public void doRender(Entity par1Entity, double par2, double par4, double par6, float par8, float par9)
    {
        this.renderTheOrb((EntityMyNewOrb)par1Entity, par2, par4, par6, par8, par9);
    }

By the way, what is this ?

int i = par1EntityMyNewOrb.getTextureByValue();

That's just the same as getTextureByXP

 

It now renders, but the orb only renders as grey. I've given it the rgb values as floats, but it just doesn't work.

@SideOnly(Side.CLIENT)
public class RenderMyNewOrb extends Render
{
private static final ResourceLocation orbTexture = new ResourceLocation("textures/entity/experience_orb.png");

    public RenderMyNewOrb()

      Weird idea on mods...

      By DDmce · Posted

      So I've read the EULA, and lets be straight...     If I split my modpack(of my mods, yeah I'm nuts) into several(many) individual mods(like just one boss) with minor additions(plus not working together), then have a complete/modpack version on patreon/onlyfans having each addon work together... Would people buy my idea?

      [1.20.2] Textures for Block States that worked on 1.16 for Tile Entity are not working for Block Entity

      By Beothorn · Posted

      I am migrating a mod from 1.16.5 to 1.20.2 The version for 1.16.5 can be found here https://github.com/beothorn/automataCraft For the block called automata_start, it uses TileEntities and has blockstates, model/block and textures on json files. This is currently working fine on 1.16.5 https://github.com/beothorn/automataCraft/tree/master/src/main/resources/assets/automata For 1.20.2 I migrated the logic from TileEntities to BlockEntity. The mod is working fine. All blocks and Items are working with the correct textures except for the textures for each state of the automata_start block. No changes where made to the json files. This is the branch I am working on (there were some refactorings, but all is basically the same): https://github.com/beothorn/automataCraft/tree/1_20/src/main/resources/assets/automata The only difference I can think that may be related is that i had to implement createBlockStateDefinition on the BaseEntityBlock: https://github.com/beothorn/automataCraft/blob/1_20/src/main/java/br/com/isageek/automata/automata/AutomataStartBlock.java#L43 This is driving me crazy. I know the jsons are being loaded as I put a breakpoint at `net.minecraft.client.resources.model.ModelBakery#loadModel` and I can see BlockModelDefinition.fromJsonElement being called with automata_start. I also printed the state from the arguments of the tick function call and they look correct (https://github.com/beothorn/automataCraft/blob/1_20/src/main/java/br/com/isageek/automata/automata/Ticker.java#L32 ): blockState Block{automata:automata_start}[state=loadreplaceables] In game, all I see is the no textures. I think it is weird it is not the "missing texture" texture so I think it may be related to the material, but I had no success tweaking it (https://github.com/beothorn/automataCraft/blob/1_20/src/main/java/br/com/isageek/automata/automata/AutomataStartBlock.java#L37).   public static final Property<AutomataStartState> state = EnumProperty.create("state", AutomataStartState.class); private final AtomicReference<RegistryObject<BlockEntityType<?>>> blockEntityType; private final Map<String, RegistryObject<Block>> registeredBlocks; public AutomataStartBlock( final AtomicReference<RegistryObject<BlockEntityType<?>>> blockEntityType, final Map<String, RegistryObject<Block>> registeredBlocks ) { super(BlockBehaviour.Properties.of().mapColor(MapColor.STONE).strength(1.5F, 6.0F)); this.blockEntityType = blockEntityType; this.registeredBlocks = registeredBlocks; this.registerDefaultState(this.getStateDefinition().any().setValue(state, AutomataStartState.LOAD_REPLACEABLES)); } @Override protected void createBlockStateDefinition(StateDefinition.Builder<Block, BlockState> stateBuilder) { stateBuilder.add(state); }     So my cry for help is, anyone has any ideas? Is there a way to easily debug this, for example somewhere where I can list the textures for a given state, or make sure this is loaded?   Thanks in advance for the hints
