[1.12.2] Void with structures


I-is-Zed

Recommended Posts

Newbie to modding here, and I'm looking to make a very particular mod. I want to have the option when creating a new world to generate a void world, except in that void world, I still want structures and villages to spawn floating in the air. Now, I have absolutely no idea how to do this, so what I need is pointers to what documentation I need to read and what things I need to learn in order to make this real.

 

Any pointers in the right direction or tips are appreciated.

In my knowledge this is probably going to be difficult to replace normal vanilla minecraft without complete rewrites, so what I suggest you do is look at tutorials for custom WorldTypes/Dimensions, they can be used it to spawn a void world, setup custom chunkgenerators and custom spawning, etc, as most vanilla structures unfortunately do checks for solid ground, you'll probably need to look at intercepting generation events, through subscribe events and creating brand new structure files that duplicate the originals without the checks, this is usually the opposite problem for custom structures in mods, where they randomly spawn in the air and you need to generate some extra code to anchor them :)

 

Also if you think of the End Dimension, its technically a void world with islands that spawn, so take a look at how that is generated too as a vanilla example, its usually what I do tbh, I think of a feature I want, then think, does vanilla generate or do something similar to what I want, then I go poke around the code and see if I can replicate/learn from said example, then I go look at tutorials/etc if I can't find an answer myself.

    • I have a problem, I am trying to put two different effects to two different armors but when I run it only the emerald armor effect works. This is the code public class ModArmorItem extends ArmorItem{ private static final Map<ArmorMaterial, MobEffectInstance> MATERIAL_TO_EFFECT_MAP = (new ImmutableMap.Builder<ArmorMaterial, MobEffectInstance>()) .put(ModArmorMaterials.EMERALD, new MobEffectInstance(MobEffects.HERO_OF_THE_VILLAGE,200, 1,false,false, true)) .put(ModArmorMaterials.OBSIDIAN, new MobEffectInstance(MobEffects.FIRE_RESISTANCE,200, 1,false,false, true)).build(); public ModArmorItem(ArmorMaterial pMaterial, Type pType, Properties pProperties) { super(pMaterial, pType, pProperties); } @Override public void onArmorTick(ItemStack stack, Level world, Player player){ if (!world.isClientSide()) { if (hasFullSuitOfArmorOn(player)) { evaluateArmorEffects(player); } } } private void evaluateArmorEffects(Player player) { for (Map.Entry<ArmorMaterial,MobEffectInstance> entry : MATERIAL_TO_EFFECT_MAP.entrySet()){ ArmorMaterial mapArmorMaterial = entry.getKey(); MobEffectInstance mapStatusEffect = entry.getValue(); if (hasCorrectArmorOn(mapArmorMaterial, player)) { addStatusEffectForMaterial(player, mapArmorMaterial, mapStatusEffect); } } } private void addStatusEffectForMaterial(Player player, ArmorMaterial mapArmorMaterial, MobEffectInstance mapStatusEffect) { boolean hasPlayerEffect = player.hasEffect(mapStatusEffect.getEffect()); if (hasCorrectArmorOn(mapArmorMaterial, player) && !hasPlayerEffect) { player.addEffect(new MobEffectInstance(mapStatusEffect)); } } private boolean hasCorrectArmorOn(ArmorMaterial material, Player player) { for (ItemStack armorStack : player.getInventory().armor){ if (!(armorStack.getItem() instanceof ArmorItem)) { return false; } } ArmorItem helmet = ((ArmorItem)player.getInventory().getArmor(3).getItem()); ArmorItem breastplace = ((ArmorItem)player.getInventory().getArmor(2).getItem()); ArmorItem leggins = ((ArmorItem)player.getInventory().getArmor(1).getItem()); ArmorItem boots = ((ArmorItem)player.getInventory().getArmor(0).getItem()); return helmet.getMaterial() == material && breastplace.getMaterial() == material && leggins.getMaterial() == material && boots.getMaterial() == material; } private boolean hasFullSuitOfArmorOn(Player player){ ItemStack helmet = player.getInventory().getArmor(3); ItemStack breastplace = player.getInventory().getArmor(2); ItemStack leggins = player.getInventory().getArmor(1); ItemStack boots = player.getInventory().getArmor(0); return !helmet.isEmpty() && !breastplace.isEmpty() && !leggins.isEmpty() && !boots.isEmpty(); } } Also when I place two effects on the same armor, the game crashes. Here is the crash file. The code is the same, only this part is different   private static final Map<ArmorMaterial, MobEffectInstance> MATERIAL_TO_EFFECT_MAP = (new ImmutableMap.Builder<ArmorMaterial, MobEffectInstance>()) .put(ModArmorMaterials.EMERALD, new MobEffectInstance(MobEffects.HERO_OF_THE_VILLAGE,200, 1,false,false, true)) .put(ModArmorMaterials.EMERALD, new MobEffectInstance(MobEffects.FIRE_RESISTANCE,200, 1,false,false, true)).build(); I hope you guys can help me. Thanks.

    • Hi, I need suggestions. I am a beginner in Minecraft Modding. I would like to apply custom effects to some armors, something like: more chance to drop seeds, change zombie awareness, drop more pieces of wood when chopping logs, and things like that. How would you recommend me to do it, is there any library that has something similar and which ones would you recommend me?.

    • You have to create an Entity class called PlayerPart and use multiple of them to make the different parts of the player. See EnderDragonPart.java source code. The green hitboxes of the dragon are all EnderDragonParts
