RadLink

⚡ RadLink

RadLink is a lightweight, flexible JSON-driven scripting engine designed for Minecraft Forge. It allows modpack creators and developers to build complex interactive mechanics, custom item behaviors, dynamic world events, and environment logic — without writing Java code or recompiling the mod.

All configuration is managed dynamically directly inside your save folder (run/saves/<WorldName>/radlink/).

🔥 Key Features

• JSON-Driven Triggers: Assign custom right-click, block-use, or world-event scripts using simple, readable JSON files.
• Built-in Math Parser: Evaluate real-time mathematical expressions with variables, support for dynamic expressions like "${global_atmosphere} / 2 >= 100".
• Branching & Sequences:
  • Group multiple actions seamlessly using run arrays.
  • Use conditional execution (If/Then and case structures) for deep logic flows.
  • Dynamic World Actions:
    • World Manipulation: explosion, set (supports fill, destroy, replace modes with block tests), summon, particle, sound.
    • Player Interactions: damage, effect, dynamic command execution, and system say / message displays.
  • Global & Entity Variables: Persistent variable tracking saved automatically in variables.json for complex stateful mechanics.

🛠️ Configuration Example

Here is an example of an item trigger featuring top-level math verification and a nested condition script:

[
  {
    "id": "my_mod:test_item",
    "name": "Test Item",
    "trigger": "right_click",
    "if": {
      "calc": {
        "expression": "${global_atmosphere} / 2",
        ">=": 100
      }
    },
    "then": [
      {
        "explosion": {
          "radius": 5.0,
          "fire": true
        },
        "run": [
          {
            "command": "title @s title {\"text\":\"Triggered!\",\"color\":\"red\"}"
          },
          {
            "command": "give @s minecraft:diamond 1"
          }
        ]
      }
    ]
  }
