Fluid Shell Extensions

Fluid Shell Extensions is an addon mod for [Create Big Cannons] that expands the fluid shell system with a flexible custom effect framework. Through simple JSON configuration files, you can add rich explosive effects to any fluid without writing a single line of code. Whether it's placing fluid sources, spawning items, applying potion effects, creating explosions, or generating particles—everything is under your control.

Features

• Fully Data-Driven – All effects are configured via JSON files. No mod code modifications required.
• Multi-Stage Effects – Trigger different effects based on the amount of fluid inside the shell.
• Multiple Effect Types – Place fluid source blocks, spawn item entities, apply potion effects, create explosions, emit particles.
• Soft Dependency Support – Set conditions based on whether specific mods are loaded for cross-mod integration.
• Detailed Logging – Easy debugging and effect tracing.

Requirements

• Minecraft 1.20.1
• Forge 47.0.0 or higher
• Required mods:
  • [Create] 6.0.0+
  • [Create Big Cannons] 5.10.2+

Configuration

Configuration files go in config/fluid_shell_extensions/effects/:

• Singleplayer: .minecraft/config/fluid_shell_extensions/effects/
• Server: server-root/config/fluid_shell_extensions/effects/

Each fluid requires its own JSON file. Naming it after the fluid's registry name (e.g., create_chocolate.json) is recommended.
