Hello,

 

Is it possible to create an image through code and texture an item with it in game?

Howdy

Yes it is

Here's a working example of texturing an item with a custom quad

https://github.com/TheGreyGhost/MinecraftByExample/tree/master/src/main/java/minecraftbyexample/mbe15_item_dynamic_item_model

DynamicTexture is suitable for creating an image in code.

If you search this forum for DynamicTexture you'll find some recents posts about dynamic textures (Elytra, wolves)

Thanks a ton!

It seems that AtlasTexture and ModelLoader.instance().getSpriteMap... is no longer the same as your guide. Do you know how accessing those things have changed?

It seems to still be correct for me

 

// we have previously registered digitsTexture in StartupClientOnly::onTextureStitchEvent
AtlasTexture blocksStitchedTextures = ModelLoader.instance().getSpriteMap().getAtlasTexture(AtlasTexture.LOCATION_BLOCKS_TEXTURE);
TextureAtlasSprite digitsTextures = blocksStitchedTextures.getSprite(digitsTextureRL);

These compile fine

 

Check you build.gradle?

@OnlyIn(Dist.CLIENT)

   private static final Logger LOGGER = LogManager.getLogger();
   @Deprecated
   public static final ResourceLocation LOCATION_BLOCKS_TEXTURE = PlayerContainer.LOCATION_BLOCKS_TEXTURE;

   public static final ResourceLocation LOCATION_PARTICLES_TEXTURE = new ResourceLocation("textures/atlas/particles.png");
   private final List<TextureAtlasSprite> listAnimatedSprites = Lists.newArrayList();
   private final Set<ResourceLocation> sprites = Sets.newHashSet();
   private final Map<ResourceLocation, TextureAtlasSprite> mapUploadedSprites = Maps.newHashMap();
   private final ResourceLocation textureLocation;
   private final int maximumTextureSize;

   public AtlasTexture(ResourceLocation textureLocationIn) {
      this.textureLocation = textureLocationIn;
      this.maximumTextureSize = RenderSystem.maxSupportedTextureSize();
   }

and

ModelBakery::

public SpriteMap getSpriteMap() {
   return this.spriteMap;
}

Ah, I got it working now thanks! (Was using a funky version of forge)

One last thing... I am having trouble properly coloring the quads:

 

https://github.com/TheGreyGhost/MinecraftByExample/blob/master/src/main/java/minecraftbyexample/mbe15_item_dynamic_item_model/ChessboardFinalisedModel.java#L287-L290

 

On these specific lines you can set a parameter to a color, if I change any of them from white to anything else it just turns teal, any ideas?

Also I just want to make sure I'm doing this efficiently. I'm trying to dynamically create a texture in game. Is the best way to do it like your example where instead of filling a chess board with diamond blocks (I'll use a blank texture), the blocks will represent each individual pixel.

 

If you get what I mean would adding these many quads cause any lag or am I doing this wrong/not efficiently?
