A05 Datapack

A custom Minecraft datapack featuring "magical" crafting systems, interactive wands, and enchanted detection mechanics. (proof of concept)

Features Implemented

Magic Wand System

• Crafting Recipe: Combine two sticks with a Nether Star in a diagonal pattern to create the Magic Wand
• Functionality:
  • Campfire Toggle: Right-click lit/unlit campfires to toggle their state
  • Soul Campfire Toggle: Same functionality for soul campfires
  • Cauldron Cycling: Right-click water cauldrons to cycle through water levels: empty → level 1 → level 2 → level 3 → empty
• Debug Particles: Optional debug visualization of wand raycast (toggle with /scoreboard players set @s show_debug_particles 1 or 0, default at 0)

Chimney System

• Smoke Markers: Wand creates invisible markers to detect lit campfires below
• Particle Effects: Displays smoke and flame particles above detected lit campfires
• Detection Range: Scans up to 20 blocks below markers for active campfires

Sneak Detection System

• One-time Activation: Triggers once per sneak hold
• Advancement Integration: Uses advancements to detect player sneaking
• Scoreboard Tracking: Tracks sneak state, duration, and prevents double-triggers

Magic Crafting System

• Recipe-based Crafting: Drop specific item combinations on the ground with water cauldrons and campfires underneath
• Current Recipes:
  1. Redstone Block Recipe: Slimeball (1) + Cobblestone (2) + Redstone (1) with cauldron level 1 (non-smokey) → Redstone Block or Dirt
  2. Emerald Block Recipe: Slimeball (1) + Stone (3) + Emerald (1) with cauldron level 2 (smokey) → Emerald Block or Dirt
• Requirements: Items must be on ground, player within 5 blocks, correct cauldron level and smoke state
• Feedback: Visual and audio feedback for correct/incorrect recipes

Scoreboards

The datapack initializes the following scoreboards:

• wand_click - Debounce flag for wand uses
• wand_hold_timer - Timer for wand hold duration
• sneak_click - Debounce flag for sneak detection
• sneak_hold_timer - Timer for sneak hold duration
• issneaking - Boolean flag for sneaking state
• sneak_duration - Tracks total sneak duration
• sneak_tick_counter - Counter for sneak ticks
• show_debug_particles - Toggle for debug particle visualization
• recipe_effects - Magic crafting system scoreboard

How to Use

Magic Wand

1. Craft the Magic Wand using sticks + nether star (diagonal pattern)
2. Hold right-click on campfires to toggle
3. Hold right-click on cauldrons to cycle water levels
4. Optional: Enable debug particles with /scoreboard players set @s show_debug_particles 1

Sneak Detection

• Simply sneak to trigger the system
• Advancement triggers once per sneak session

Magic Crafting

1. Place a water cauldron where you want to craft
2. If recipe requires smoke, place active (soul) campfire below
3. Drop the required items inside the cauldron
4. Stand within 5 blocks - recipe will trigger if all conditions met
5. Receive the crafted item or failure particles/sound

Chimney/Smoke System

• Markers automatically detect lit campfires within 20 blocks below them

Technical Details

• Raycast System: Uses semistep raycasting for accurate block detection
• Debouncing: Click flags prevent multiple triggers per use
• Macro Functions: Magic crafting uses function macros with dynamic parameters
• Storage: Uses id:data and id:temp NBT storage for recipe management

Known Issues / TODO

• Recipe system could be expanded with more recipes
• Adding weapon system with magic
• Adding player stats
