Viewing mods with logos in Mod List screen causes drastic memory leak

Recommended Posts

I was testing some mods today (putting one mod in the mods folder at a time), and discovered a massive memory leak. After testing several mods, I determined it is a bug with FML rather than any specific mod.

 

Repro steps are simple:

  1. [*]Place in the mods folder a mod which contains a logo (has a logoFile entry in mcmod.info)

[*]Run Minecraft

[*]Click Mods button

[*]Click entry for the mod

It will show the info for the mod as well as the graphic file for its logo. It will also cause javaw.exe to start eating memory like crazy (you can easily see this in the Task Manager).

 

Notes:

  • Clicking the entry for another mod that does not contain a logo will stop the leak, but the current usage does not go down (memory not released). Clicking a mod with a logo again will resume eating memory.
  • Not clicking any mods with logos/clicking only mods without logos does not trigger a leak
  • It happens with the latest FML (9.11.1.1345 for MC 1.6.4)
  • There are no threads in the forum which mention both "memory leak" and "logo"

    • Try deliting feur builder  It caused this issue in my modpack
    • 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)
    • nvm found out it was because i had create h and not f
    • Maybe there's something happening in the 'leather armor + dye' recipe itself that would be updating the held item texture?
    • @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?
