Hello, i am currently developing mod, which bring clans into the game and i need  pass the clan's icon from server to client. This icon have a light weight (it's 16x16) and i think it will be good to keep them all in ./icons folder of the Minecraft directory. But i don't know to convert File to ResourceLocation to render it in the game. Can somebody help me with this?

1. Pack all .png to 256x256 sheet.

2. Put that sheet somewhere in server files.

3. Create SpecialResourcePack extends AbstractResourcePack (or FileResourcePack).

4. Use packets (send .png as stream): either SimpleNetworkWrapper or setup your own sending (open new thread)

5. On receiver (client) side you will now have some .png - use SpecialResourcePack to load image as resource (inputStream).

6. Use:

mc.getTextureManager().bindTexture(textureSheet);
this.drawTexturedModalRect(x, y, u, v, 16, 16);

To draw image.

 

Note: Instead of writing whole new implementation of ResourcePack you can use FileResourcePack.

1. After finishing downloading .png, place it into .zip or .jar (on client side).

2. Load .jar/.zip as FileResourcePack.

3. That way you will also inherit file structure (e.g: assets/something/lol/textureSheet.png) of that .jar.

 

Example of loading FileResourcePack:

List<IResourcePack> defaultResourcePacks = ObfuscationReflectionHelper.getPrivateValue(Minecraft.class, Minecraft.getMinecraft(), "defaultResourcePacks", "field_110449_ao");

defaultResourcePacks.add(new MyFileResourcePack(new File("C:/Users/Me/Something/.minecraft/theJar.jar")));
Minecraft.getMinecraft().refreshResources();
