Better Happy Ghast

Adds a parked state to the vanilla Happy Ghast (1.21.x):

• Toggle parked with a Blaze Rod (only if the ghast has a harness).
• While parked and unmounted, it stays perfectly still.
• While parked and mounted, it flies faster (configurable multiplier).
• Optional visual feedback (glow + particles when toggling).
• Includes simple JSON config.

Fabric mod for Minecraft 1.21.x.

Requirements

• Fabric Loader ≥ 0.15.0
• Fabric API for your Minecraft 1.21.x version

Installation

1. Install Fabric Loader and Fabric API.
2. Download the mod JAR from the Releases.
3. Drop the JAR into your mods/ folder:
   • Windows: %AppData%/.minecraft/mods
   • Linux: ~/.minecraft/mods
   • macOS: ~/Library/Application Support/minecraft/mods
4. Launch the game.

How to use

• Put a Harness on a Happy Ghast (vanilla behavior).
• Right-click with a Blaze Rod to toggle parked on/off.
  • Parked (unmounted): stays in place.
  • Parked (mounted): flies faster than normal.
• Right-click with empty hand to mount as usual (vanilla).

Configuration

A JSON file is created on first run:

.minecraft/config/better-happy-ghast.json

Default fields:

{
  "parkedSpeedMultiplier": 2.0,
  "sprintMultiplier": 1.25,
  "maxSpeed": 1.6,
  "debugLogs": true,
  "debugEveryTicks": 20
}

• parkedSpeedMultiplier – base speed multiplier when parked + mounted.
• sprintMultiplier – extra multiplier if sprint/jump signal is detected (kept for future; not required if you disabled sprint logic).
• maxSpeed – hard cap on velocity length to avoid runaway speeds.
• debugLogs – prints diagnostic info to latest.log.
• debugEveryTicks – how often to print periodic speed logs (20 = ~1 sec).

After editing the JSON, restart the game.

Compatibility

• Minecraft: >= 1.21, < 1.22
• Loader: Fabric
• Not tested with Forge/NeoForge.
• Should be compatible with most content mods; anything replacing Happy Ghast internals might conflict.

Building from source

# Windows PowerShell
.\\gradlew.bat clean build
# macOS/Linux
./gradlew clean build

Artifacts will be in build/libs/.
Publish the remapped jar (no -dev / -sources suffix).

Troubleshooting

• “Incompatible mods / requires ${minecraft_version}”: make sure your fabric.mod.json expands placeholders (or use a fixed range like >=1.21 <1.22).
• If the Blaze Rod mounts you instead of toggling parked: ensure the ghast has a harness; the Blaze Rod action is intercepted only in that case.
• Speed feels off: adjust parkedSpeedMultiplier and maxSpeed. Enable debugLogs to see live speed in latest.log.
