Loading & Rendering Item Texture during Run Time

[CAS_ual_TY]

Hello,

 

I am currently working on bringing a trading card game to minecraft. Informations are read from public online APIs, including the cards' look.

 

The card images are being downloaded when the player can see the respective card. Alternatively I could also implement a downloading of all images beforehand, but there are quite a lot of cards out there so I would prefer not to do it that way.

 

Which brings me to my point: How do I render an external texture for my item?

 

I followed the structure of this: https://github.com/TheGreyGhost/MinecraftByExample/tree/master/src/main/java/minecraftbyexample/mbe15_item_dynamic_item_model

 

I have the location of the File/BufferedImage but I do not know how to load it in, without reloading all textures.

 

Code of the IBakedModel that is being called once the texture is downloaded and ready (I think it is pretty obvious that I have no idea how to do it, the code was just an experiment):

 

public class CardIBakedModelCardID implements IBakedModel
{
	public IBakedModel modelMain;
	private int cardID;
	private List<BakedQuad> list = null;
	
	public CardIBakedModelCardID(IBakedModel modelMain, int cardID, BufferedImage image)
	{
		this.modelMain = modelMain;
		this.cardID = cardID;
	}
	
	@Override
	public List<BakedQuad> getQuads(@Nullable IBlockState state, @Nullable EnumFacing side, long rand)
	{
		if(this.list == null)
		{
			this.list = new ArrayList<BakedQuad>();
			List<BakedQuad> list2 = this.modelMain.getQuads(state, side, rand);
			
			for(BakedQuad quad : list2)
			{
				Minecraft mc = Minecraft.getMinecraft();
				DynamicTexture dt = new DynamicTexture(Main.getImageForID(this.cardID));
				ResourceLocation rl = mc.getTextureManager().getDynamicTextureLocation(Main.MOD_ID + ":" + "card" + this.cardID, dt);
				TextureAtlasSprite tas = mc.getTextureMapBlocks().registerSprite(rl);
				this.list.add(new BakedQuadRetextured(quad, tas));
			}
		}
		
		return this.list;
	}

	@Override
	public boolean isAmbientOcclusion() {
		return this.modelMain.isAmbientOcclusion();
	}

	@Override
	public boolean isGui3d() {
		return this.modelMain.isGui3d();
	}

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

	@Override
	public TextureAtlasSprite getParticleTexture() {
		return this.modelMain.getParticleTexture();
	}

	@Override
	public ItemOverrideList getOverrides() {
		throw new UnsupportedOperationException("The finalised model does not have an override list.");
	}
}

 

Everything else is working already, this code is also being called, but the texture ingame is simply nothing / transparent.

 

I hope someone can help me and everything I thought out is possible.

 

Thanks in advance!

Thanks! Kinda what I expected.

 

Almost everything seems to be working, I still have a problem however, It doesnt seem like my textures get loaded from outside the jar. I am getting an error that these textures could not be found. Anyone got any idea?

 

	@SubscribeEvent
	public void stitcherEventPre(TextureStitchEvent.Pre event)
	{
		File[] images = this.cardImageDir.listFiles();
		
		for(File f : images)
		{
			try
			{
				Minecraft mc = Minecraft.getMinecraft();
				DynamicTexture dt = new DynamicTexture(ImageIO.read(f));
				ResourceLocation rl = mc.getTextureManager().getDynamicTextureLocation(TCG.MOD_ID + ":" + "card_" + f.getName().replace("_1.png", ""), dt);
				TextureAtlasSprite tas = event.getMap().registerSprite(rl);
				System.out.println(tas.getIconName()); //TODO debug
				System.out.println("");
			}
			catch(Exception e)
			{
				e.printStackTrace();
			}
		}
	}

IRessourcePack is literally a dream when it comes to this, thanks! Everything works now. Did I "register" (add) the rp correctly? (I know, the field_xxx String is missing. you wouldnt know it by any chance?)

 

EDIT: Unless it got changed it is getPrivateValue(Minecraft.class, Minecraft.getMinecraft(), "defaultResourcePacks", "field_110449_ao", "ap") I think

 

For people who will google this:

 

public class ResourcePackCards implements IResourcePack
{
	private File cardImageDir;
	
	public ResourcePackCards(File cardImageDir)
	{
		this.cardImageDir = cardImageDir;
	}
	
	@Override
	public InputStream getInputStream(ResourceLocation location) throws IOException
	{
		return new FileInputStream(new File(this.cardImageDir.getAbsolutePath() + "/" + location.getResourcePath().replace("textures/", "")));
	}
	
	@Override
	public boolean resourceExists(ResourceLocation location)
	{
		return new File(this.cardImageDir.getAbsolutePath() + "/" + location.getResourcePath().replace("textures/", "")).exists();
	}
	
	@Override
	public Set<String> getResourceDomains()
	{
		return ImmutableSet.<String>of(Main.MOD_ID);
	}
	
	@Override
	public <T extends IMetadataSection> T getPackMetadata(MetadataSerializer metadataSerializer, String metadataSectionName) throws IOException
	{
		return null;
	}
	
	@Override
	public BufferedImage getPackImage() throws IOException
	{
		return TextureUtil.readBufferedImage(DefaultResourcePack.class.getResourceAsStream("/" + (new ResourceLocation("pack.png")).getResourcePath()));
	}
	
	@Override
	public String getPackName()
	{
		return "Cards Images";
	}
	
}

//in preInit (client side only)
List<IResourcePack> defaultResourcePacks = null;
defaultResourcePacks = ReflectionHelper.getPrivateValue(Minecraft.class, Minecraft.getMinecraft(), "defaultResourcePacks");
defaultResourcePacks.add(new ResourcePackCards(this.cardImageDir));
Minecraft.getMinecraft().refreshResources();

Do not call refreshResources, other than that it looks fine.

If I dont call it I get missing texture errors.

 

Also, currently I am loading in exactly 8313 textures. When using 128x128 textures everything works fine. When using 256x256 textures, however, I am getting the bottom error. Does this happen because my PC is too weak or because the texture atlas is too small or rather it can not fit everything?:

Im doing it at the end of preInit. Which event would I need then?

Your (and probably most other) graphics cards cannot support a texture that size (over 2,000,000 pixels squared...). Why are you loading that many block textures?

Expand  

Well, as I said, trading card game with 8313 cards so far. By default, all cards have the same look in their Item form (all use the back side). But you can enable an option, which, instead, lets every single card item use the respective texture. Additionally, you can choose the size of these textures (default: 128).

In the playing GUI, cards are always using the correct picture.

In case you are still wondering, now youd get the rough idea. Spoiler because I am not a fan of advertising in support forums.
