Item's onUpdate method & Containers

Posted January 29, 201411 yr

Hey guys,

I'm trying to make an item which decays. While it's in your inventory, the onUpdate method triggers NBT which increases by 1 each time the method is called.

However, when placed into a chest, it seems the onUpdate method stops; my timer no longer ticks.

Firstly, is there any way to stop this happening?

HOWEVER- I have certain containers (added by my mod), which I want this exact effect to happen. So, I need to stop it happening in most chests etc, but in these particular blocks it needs to freeze just like that.

Anyone got any ideas?

There is no solution for this.

Chests do not give update ticks to their contents.

(Neither do ItemFrames).

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable. If you think this is the case, JUST REPORT ME. Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

You could compare with the world time. The item timer would catch up to the real value as soon as you take it from the chest, and gets destroyed/unusable/whatever.

Tricky, but doable.* Also annoying (player perspective) when you pick the item up and it vanishes.

*Use world.getWorldInfo().getWorldTotalTime() there are at least two other "time" methods, neither of which is the one you'd want. WorldTotalTime is tracked by how long the server (or single player instance) is active.

I guess so...

You could use the GuiOpenEvent to perform the item timer catch up a bit sooner.

Or if it is something extremely important, use the loaded tile entities list in world, with a world tick, to "tick" their content yourself.

Personally I'd be happy with a function on Item that gets called (once) when the item is put into a container (or item frame) so that "permanent" effects can get cleared without having to make every effect a potion effect (or similar) that ticks separately.

Instead I check to see if the player has an inventory open (that isn't their own, unless creative) and revoke whatever bonus the item gives, so that if the player DOES put the item into the chest the effect doesn't linger inappropriately.

Which just leaves item frames.

How to add my mob to another mod's biome in 1.20.1.

You can add mob spawns using Forge's Biome Modifiers feature. I won't go into details on how to use a data generator for them, but here's a simple example:
{ "type": "forge:add_spawns", // Required "biomes": "#namespace:biome_tag", // Accepts a biome id, [list of biome ids], or #namespace:biome_tag "spawners": { "type": "namespace:entity_type", // Type of mob to spawn "weight": 100, // int, spawn weighting "minCount": 1, // int, minimum pack size "maxCount": 4 // int, maximum pack size } }This JSON file would go somewhere like this: data/modid/forge/biome_modifier/your_biome_modifier.json

How to change player renderer and transform model parts?

I have been trying for a while now to make a custom player renderer, and replace the vanilla player renderer with it. So far I've come up with a custom player renderer class that extends vanilla PlayerRenderer:
package com.FireDude123.BOTW.entity.renderer; import com.mojang.blaze3d.vertex.PoseStack; import net.minecraft.client.player.AbstractClientPlayer; import net.minecraft.client.renderer.MultiBufferSource; import net.minecraft.client.renderer.entity.player.PlayerRenderer; import net.minecraft.client.renderer.entity.EntityRendererProvider; import net.minecraftforge.client.event.RenderPlayerEvent; import net.minecraftforge.common.MinecraftForge; public class PoseablePlayerRenderer extends PlayerRenderer { public PoseablePlayerRenderer(EntityRendererProvider.Context ctx, boolean slim) { super(ctx, slim); System.out.println("here too"); } @Override public void render(AbstractClientPlayer p_117788_, float p_117789_, float p_117790_, PoseStack poseStack, MultiBufferSource p_117792_, int p_117793_) { System.out.println("didnt get here lol"); model.leftArm.xRot=(float)Math.toRadians(160); super.render(p_117788_, p_117789_, p_117790_, poseStack, p_117792_, p_117793_); } } As you can see, the intended purpose of this is to raise the player's left arm by 160 degrees. However, combined with this logic in ClientModEvents:
@Mod.EventBusSubscriber(modid = MODID, bus = Mod.EventBusSubscriber.Bus.MOD, value = Dist.CLIENT) public static class ClientModEvents { @SubscribeEvent public static void onClientSetup(FMLClientSetupEvent event) { EntityRenderers.register((EntityType<? extends AbstractClientPlayer>)(EntityType<?)EntityType.PLAYER, ctx -> new PoseablePlayerRenderer(ctx, true)); EntityRenderers.register(Entities.MAGNESIS_BLOCK.get(), com.FireDude123.BOTW.entity.renderer.BlockDisplayRenderer::new); EntityRenderers.register(Entities.REMOTE_BOMB.get(), ThrownItemRenderer::new); EntityRenderers.register(Entities.CRYONIS_ICE.get(), com.FireDude123.BOTW.entity.renderer.BlockDisplayRenderer::new); EntityRenderers.register(Entities.STASIS_BLOCK.get(), FallingBlockRenderer::new); } @SubscribeEvent public static void registerLayerDefinitions(EntityRenderersEvent.RegisterLayerDefinitions event) { event.registerLayerDefinition(new ModelLayerLocation(new ResourceLocation(BOTW.MODID, "paraglider"), "main"), ParagliderLayer::createBodyLayer); } }(I also have a paraglider layer here for something else, it's working perfectly fine, also I used the slim setting because the player is slim in 1.20.1 forge)
This logic isn't replacing the renderer, as far as I can tell. Can someone please advise as to why, and how to fix it?

How to add my mob to another mod's biome in 1.20.1.

I'm on 1.20.1 and was wondering if there was a way to add a mob I am going to make to a other mod's biome (Regions Unexplored in this case). I am trying to figure this out before I start coding the mod. Could someone point me to a good guide on this? I saw some things about biome modifier's but all the resources are either to short, unhelpful or for a different version. Thanks in advance. (i am a beginner but i have java and modding knowledge so this isn't like a "i am new and don't know anything about coding" problem btw)

Help with file conversion

Many Forge users seek help with file conversions. Similarly, managing your health can benefit from structured tools like the https://wellness-app.com/calculator/fasting-calculator/ and a free intermittent fasting calculator. These tools help you plan and personalize your fasting and eating windows based on your lifestyle and goals. By entering your preferred fasting duration and meal times, you receive a tailored schedule that makes intermittent fasting easier to follow. Just as mastering file conversions improves modding success, using a fasting calculator brings clarity and structure to your health routine, supporting better results over time.

Cobblemon invalid player data

Hi everyone, I keep getting "invalid player data" when trying to log onto my friend's server. Log analysis says to remove Night Lights and ImmediatelyFast, but that doesn't work. Any insight is appreciated
