I'm stumped. I currently began a re-write of my mod to remove as much version dependency as possible. This involved switching from Notch names to Srg names and switching my @IFMLLoadingPlugin.SortingIndex() from 100 to 1001 to run all changes post runtime deobfuscation. This worked perfectly well, but once I went on to testing out an idea for finding a LocalVariableNode's index based on it's name/desc I ran into something I don't quite understand.

 

public void setIsSpawningFromSpawnerTrue(MethodNode method)
{
	BnBTweaks.Log.info("Printing " + method.localVariables.size() + " LocalVariableNodes in: " + method.name);
	for (LocalVariableNode lvNode : method.localVariables)
	{
		BnBTweaks.Log.info(lvNode.name + " " + lvNode.desc + " " + lvNode.index + " " + lvNode.signature);
	}

 

Above is a code snippet I wrote to get some information about local variables within the current method that I could use to write a method for finding the local variable indexs. Back when I was running pre runtime obfuscation, this would've printed out everything quite nicely for me. Now that I'm running post though, it seems that method.localVariables.size() is 0, and therefore I can get no information.

[11:27:52] [server thread/INFO] [bnBTweaks/]: Printing 0 LocalVariableNodes in: func_98278_g

 

Why might this be?

Haha, of course! As usual, the thing I got stuck on was obvious from outside the cloud of frustration :P. Wish I had thought to check the thread again before deleting literally everything and re-downloading to be sure it wasn't a corruption issue :P.

 

Now to just think of some other way to verify variables are correctly targeted (without using a second transformer :P). Can't think of a different approach yet though....

 

I feel properly dumb now :D. Many thank yous diesieben07!

      [1.18.2] Custom armor set extending DyeableArmorItem is dye-able, but not displaying

      By CatzRule81 · Posted

      I am not using hardcoded recipes, I'm using Vanilla's already existing code for leather armor dying. (via extending and implementing DyeableArmorItem / DyeableLeatherItem respectively) I have actually figured out that it's something to do with registering item colors to the ItemColors instance, but I'm trying to figure out where exactly in my mod's code I would be placing a call to the required event handler. Unfortunately the tutorial is criminally undescriptive. The most I've found is that it has to be done during client initialization. I'm currently trying to do the necessary setup via hijacking the item registry since trying to modify the item classes directly (via using SubscribeEvent in the item's constructor didn't work. Class so far: // mrrp mrow - mcmod item painter v1.0 - catzrule ch package catzadvitems.init; import net.minecraft.client.color.item.ItemColors; import net.minecraft.world.item.Item; import net.minecraftforge.registries.ObjectHolder; import net.minecraftforge.fml.event.lifecycle.FMLClientSetupEvent; import net.minecraftforge.fml.common.Mod; import net.minecraftforge.eventbus.api.SubscribeEvent; import net.minecraftforge.client.event.ColorHandlerEvent; import catzadvitems.item.DyeableWoolArmorItem; @Mod.EventBusSubscriber(bus = Mod.EventBusSubscriber.Bus.MOD) public class Painter { @ObjectHolder("cai:dyeable_wool_chestplate") public static final Item W_CHEST = null; @ObjectHolder("cai:dyeable_wool_leggings") public static final Item W_LEGS = null; @ObjectHolder("cai:dyeable_wool_boots") public static final Item W_SOCKS = null; public Painter() { // left blank, idk if forge throws a fit if constructors are missing, not taking the chance of it happening. } @SubscribeEvent public static void init(FMLClientSetupEvent event) { new Painter(); } @Mod.EventBusSubscriber private static class ForgeBusEvents { @SubscribeEvent public static void registerItemColors(ColorHandlerEvent.Item event) { ItemColors col = event.getItemColors(); col.register(DyeableUnderArmorItem::getItemDyedColor, W_CHEST, W_LEGS, W_SOCKS); //placeholder for other dye-able items here later.. } } } (for those wondering, i couldn't think of a creative wool helmet name)

      [1.18.2] Custom armor set extending DyeableArmorItem is dye-able, but not displaying

      Maybe there's something happening in the 'leather armor + dye' recipe itself that would be updating the held item texture?

      [1.20.1] Difficulty getting custom player model to render

      By Shipwrecker · Posted

      @SubscribeEvent public static void onRenderPlayer(RenderPlayerEvent.Pre e) { e.setCanceled(true); model.renderToBuffer(e.getPoseStack(), pBuffer, e.getPackedLight(), 0f, 0f, 0f, 0f, 0f); //ToaPlayerRenderer.render(); } Since getting the render method from a separate class is proving to be bit of a brick wall for me (but seems to be the solution in older versions of minecraft/forge) I've decided to try and pursue using the renderToBuffer method directly from the model itself. I've tried this route before but can't figure out what variables to feed it for the vertexConsumer and still can't seem to figure it out; if this is even a path to pursue.  The vanilla model files do not include any form of render methods, and seem to be fully constructed from their layer definitions? Their renderer files seem to take their layers which are used by the render method in the vanilla MobRenderer class. But for modded entities we @Override this function and don't have to feed the method variables because of that? I assume that the render method in the extended renderer takes the layer definitions from the renderer classes which take those from the model files. Or maybe instead of trying to use a render method I should be calling the super from the renderer like   new ToaPlayerRenderer(context, false); Except I'm not sure what I would provide for context? There's a context method in the vanilla EntityRendererProvider class which doesn't look especially helpful. I've been trying something like <e.getEntity(), model<e.getEntity()>> since that generally seems to be what is provided to the renderers for context, but I don't know if it's THE context I'm looking for? Especially since the method being called doesn't want to take this or variations of this.   In short; I feel like I'm super super close but I have to be missing something obvious? Maybe this insane inane ramble post will provide some insight into this puzzle?
