Please check my [wiki](https://github.com/YeeticusFinch/KimetsunoyaibaTweaks/wiki) for more information. Join us on [Discord](https://discord.gg/W8K962vQFT) --- ## Frequently Asked Questions ### Demon Alchemy help? - Please see [Demon Alchemy Wiki](https://github.com/YeeticusFinch/KimetsunoyaibaTweaks/wiki/Demon-Alchemy) ### How do I do the Tamayo mission? - The quest system is still work in progress, the Tamayo mission hasn't been implemented yet ### What do I do after Final Selection? - Take your ore to a swordsmith and get your sword (see How do I get to swordsmith village?) ### How do I get sun breathing? - Wait for the mod to update, the new sun breathing is WIP - Or go into the config and disable enhanced black sword, that will let you use Orca's black sword from the base mod ### How do I get to swordsmith village? - Go find a kakushi, hold a scarlet ore in your hand, then the kakushi will ask if you want to go to the swordsmith village. Click YES, and then equip the blindfold on your head slot - To find a Kakushi, open the meditatio nmenu (by sitting on a cushion), and click hte Navigation tab, and then scroll down to "Swordsmith Village" on that list of locations in the bottom left, and click on Swordsmith Village to select it. Your crow will now point you towards the nearest Kakushi entity ### Help I have the item stacking glitch - There is a glitch where if you hold an item then suddenly new items of that same type will no longer be able to stack on that item - "_if i tried picking up 4 blocks of wood one would just go into another corner while the other 3 were in a stack_" - **FIX: update to version 1.6.443 or higher** ### Where did the the custom swords go? - The new swords (like ice and frost) are now in KnY Extra Additions - curseforge.com/minecraft/mc-mods/kny-extra-additions - https://modrinth.com/mod/kny-extra-additions - https://github.com/YeeticusFinch/KnY-Extra-Additions/ ### My world creation is stuck at 100% - UPDATE: Region files for Mt Fujikasane and Swordsmith Village are now in this mod: - [https://modrinth.com/mod/kny-worlds](https://modrinth.com/mod/kny-worlds) - This means that Mt Fujikasane isn't importing properly - Try upgrading to the latest version of Kimetsunoyaiba Tweaks - Otherwise, you can fix it manually: - Go to your .minecraft folder --> kimetsunoyaibamultiplayer --> mt_fujikasane_cache - If this folder is empty, then you've got a problem - https://github.com/YeeticusFinch/KimetsunoyaibaTweaks/tree/main/region - ^^ Download all the region files from this GitHub link - Place all those .mca files into minecraft/kimetsunoyaibamultiplayer/mt_fujikasane_cache/ - Reload the mod and try again ### Where can I get help with this mod? - I don't usually check comments on the mod page - If you need support, please join on discord: https://discord.gg/W8K962vQFT - Or send an email to [email protected] ### The game crashes on mod loading - Make sure you have forge 47.4.0 - Make sure you have the forge versions for 1.20.1 for all the following dependency mods - Kimetsunoyaiba - Mob Player Animator - Player Animator - GeckoLib - KnY Worlds - Make sure you don't have Optifine, it's completely incompatible ### My spawns are messed up, there are no Hashira or Kizuki demons or named characters spawning? - Go into the config for Kimetsunoyaiba Tweaks (aka Kimetsunoyaiba Multiplayer) - Disable enhanced spawning - Enhanced Spawning will prevent named characters, hashira, and kizuki demons from spawning - outside of raids and quests and special biomes/structures ### How do I configure this mod? - I recommend using a config mod, like Configured or Forge Config Menus - Alternatively, you can go into your minecraft folder --> config --> Kimetsunoyaiba Multiplayer - You can edit the .toml files directly ### Missing textures - Yes sorry I haven't finished making all the assets yet --- ## Features ### Quest System This mod adds a new quest system for players in 4 different tracks: demon slayers, demons, kakushi, and swordsmiths. See the [Quests Wiki](https://github.com/YeeticusFinch/KimetsunoyaibaTweaks/wiki/Quests) for up-to-date information on the quest system. The quests are still in early beta. ### Meditation Menu To access the meditation menu, right click a cushion to sit on it, and then click the meditate button. The meditation menu gives you access to stats (your current rank, how many kills...), navigation (selecting your waypoint, you can set it to navigate to a quest or a location, good for finding structures), and skills (essential for demons). ### Custom Blood Demon Art Builder The Custom Blood Demon Art Builder is accessed in the Skills tab in the Meditation Menu (access it by sitting on a cushion). You can select your eyes, and you can select a color and particles for your custom blood demon art. As you level up, you will unlock more slots for forms for your blood demon art. Each form is a list of moves. First form can only have one move, second form can have up to two moves, third form can have up to three moves... There are some basic moves that every demon player starts with (like punch and front flip). To unlock more moves, use Demon Alchemy to make Catalysts. ### CustomNPC Support This mod offers basic support for Custom NPCs to use nichirin swords and breathing forms. ### Animation Synchronization - **Multiplayer Animation Support**: Makes PlayerAnimator animations visible to all players in multiplayer - Detects when a player starts/stops an animation - Sends animation data (player, animation name, looping flag) to the server - Server rebroadcasts animations to all nearby clients - Uses MobPlayerAnimator to display animations on other players - Works in both **LAN** and **dedicated servers** ### Sword Display System - **Visual Sword Display**: Nichirin swords are displayed on your character when not being held - Automatically places swords in sheaths on your hip or back when stored in inventory - Supports up to 2 swords displayed simultaneously (left and right positions) - Swords disappear from display when equipped or removed from inventory - **Fully Configurable**: - Choose between hip or back placement - Adjust position, rotation, and scale for each sword independently - Separate configurations for left/right and hip/back positions - Config location: `config/kimetsunoyaibamultiplayer/sword_display.toml` ### Sword Slash Effects - **Sword Slashes**: Configurable visual effects when swinging nichirin swords - Can be configured to display as sword slash entities or as particles ### Quest Familiars - Quest markers - Enhanced Kasugai crow - Nakime Eye familiar (for demons) - Orochi familiar (for demons) ### Enhanced Breathing Styles - Animated whip sword for love breathing - Better dual wielding for beast breathing - Revamped mist breathing ### Demon Slayer Locations (requires KnY Worlds addon) - Swordsmith Village - Final Selection Mountain - Improved Infinity Castle --- ## Requirements - **Minecraft Forge** `1.20.x` (other versions may work but are untested). - **PlayerAnimator** mod (installed on both client and server). - **MobPlayerAnimator** mod (installed on both client and server). - Other mods that use PlayerAnimator (e.g. Kimetsu no Yaiba). --- ## Installation 1.
