I am testing out templates and am trying to write one to NBT to see the structure of the NBT tag, however, even though I am just loading a vanilla file, it always throws an out of range exception.

 

Template template = server.getStructureTemplateManager().getTemplate(new ResourceLocation("minecraft:shipwreck/sideways_fronthalf_degraded"));
NBTTagCompound c = template.writeToNBT(new NBTTagCompound());

 

 Looking at the actual Template::writeToNBT method, it looks like here the first j is supposed to be an l, as in this case 'blocks' has only 8 items, but each of those items has 250+ plus inside them and looking at the surrounding for loops this seems to make sense.

 

for(int l = 1; l < this.blocks.size(); ++l) {
   Template.BasicPalette template$basicpalette1 = list.get(l);
   template$basicpalette1.addMapping((this.blocks.get(j).get(j)).blockState, k);
}

 

Am I missing something here? I am just trying to write a vanilla template to NBT and it fails?

Bump

Don't bump your own threads, but yes this looks like a vanilla bug in their writer.

Fixed in Forge https://github.com/MinecraftForge/MinecraftForge/commit/8c44d6d4cba509c47c7c248abb48248bcf277a37

Yeah sorry about the bump, won't do it again. But thanks nonetheless.
