Dimensional Structure Restrict

DimStructRestrict is a lightweight Minecraft Forge mod for Minecraft 1.20.1 that allows you to control where structures can spawn based on dimension and structure rules. Designed and developed by Troy Cook (@cookta2012), this mod provides fine-grained control over world generation behavior — especially useful for modpack developers and world designers.

Initial release will be 1.20.1 other versions will be coming later.

🌍 Features

• Prevent or allow specific structures from generating in specific dimensions.
• Define whitelist or blacklist rules.
• Optionally flag structures to not place the structure while it believes it placed it.
• JSON-based configuration — supports comments and regenerates missing keys automatically.
• Logs rule enforcement with structure/dimension context for debugging.

🔧 Configuration

The config file is located at:

<minecraft_root>/config/dimstructrestrict.json

If the file doesn't exist, it will be generated with example entries.

📐 Structure of dimstructrestrict.json

{
  "structures": [
    {                                       // Individual structure rules will override dimension rules FULL STOP
      "id": "minecraft:village_plains",     // Structure ID
      "whitelist": ["minecraft:overworld"], // Allowed dimensions
      "false_place": false,                 // If true, the structure will be "falsely placed" (may break mods)
      "active": true                        // Whether this rule is active
    }
  ],
  "dimensions": [
    {
      "id": "minecraft:overworld",        // Dimension ID
      "whitelist": [],                    // Structures allowed in this dimension
      "active": true
    }
  ]
}

🧠 Rule Types

✅ whitelist

Only listed dimensions or structures are allowed.

❌ blacklist

Listed dimensions or structures will be prevented.

⚙️ false_place (optional, default false)

If true, prevents the structure from placing without skipping the generation step meaning it is marked on the map as generated.

⚠️ May cause issues with some structure-dependent mods.

🔄 active (optional, default false)

Controls whether the rule is enforced. Useful for temporarily disabling rules without removing them.

🧪 Example Use Case

{
  "structures": [
    {
      "id": "minecraft:ruined_portal",
      "blacklist": ["minecraft:the_end", "minecraft:the_nether"],
      "active": true
    }
  ],
  "dimensions": [
    {
      "id": "minecraft:overworld",
      "whitelist": ["minecraft:village_savanna", "minecraft:village_plains"],
      "false_place": true,
      "active": true
    }
  ]
}

🛠️ Advanced Setup

The mod uses a generic Rule system internally with two maps:

• STRUCTURE_RULES for structure-specific rules
• DIMENSION_RULES for dimension-based restrictions

Each Rule is backed by:

• id: ResourceLocation
• mode: WHITELIST or BLACKLIST
• resource: Set of targets (structure/dimension IDs)
• false_place: Boolean
• active: Boolean
