[1.7.2] Custom vanilla block drop

Posted June 10, 201411 yr

In the mod that I'm working on I need to make it so that BlockMonsterSpawner (vanilla) drops a MobCage (my mod) when it is destroyed. I've looked for a @SubscribeEvent to use but cannot find one for block destruction, and as such have come to believe that there is not a way to do so without editing BlockMonsterSpawner.class.

My question, therefore, is twofold:

[*]Is there a way to modify or add to vanilla block drops in Forge? (The version I have in my environment is the current Recommended (10.12.1.1060).)

[*]If not, as I suspect and have seen several times from repeated googling, how should I go about changing the getItemDropped(int, Random, int) and quantityDropped(Random) methods to make BlockMonsterSpawner drop a MobCage? As is in Eclipse I cannot just edit the Minecraft files as they are read-only (as they should be).

Thank you in advance for your help for a beginning modder. If you're interested, my workspace is Eclipse as set up by Wuppy in his tutorial on setting up Forge development enviroment (http://www.wuppy29.com/minecraft/modding-tutorials/wuppys-minecraft-forge-modding-tutorials-for-1-7-set-up-part-2b-advanced-forge-setup/).

Subscribe to Blockevent.Blockbreak event. Check that is the block is a spawner and add your item to the drops list

As seems always the case, the OP has solved their own problem moments after posting it due to finding something they originally overlooked.

When looking one more time in net.minecraftforge.event I found that net.minecraftforge.event.BlockEvent held a class HarvestDropsEvent that does exactly what I wanted to.

By pushing a(n?) @SubscribeEvent on(HarvestDropsEvent) to MinecraftForge.EVENT_BUS I was able to hook an event that if the block that checks for dropping happens to be an instanceof BlockMonsterSpawner to add an ItemStack(mobCage, 1) to the drop queue.

I hope that in the future people searching for how to do Custom Vanilla Block Drops in Forge can find this thread or do what I have done and find it themself so they can continue on and make great (or at least working) mods.

Oh, and thanks for answering Degubi, but you were a little too slow

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
