 # Minecraft-Error-Codes
-The pages for errors codes that can be generated by a diagnoser and referenced
+
+Documentation for error codes generated by the [Blockception Minecraft Bedrock Language Server](https://github.com/Blockception/minecraft-bedrock-language-server). When you click on an error code in your IDE, you are directed to the corresponding page in this repository.
+
+## How Error Code URLs Work
+
+String error codes use dots as separators and map directly to file paths in this repository:
+
+```
+behaviorpack.entity.event.missing
+→ behaviorpack/entity/event/missing.md
+```
+
+Numeric error codes link to the [codes/main.md](./codes/main.md) page with a fragment anchor.
+
+## Error Code Naming Convention
+
+Error codes follow the pattern `<category>.<subcategory>.<type>.<detail>`:
+
+- **category** — The top-level area: `behaviorpack`, `resourcepack`, `minecraft`, `general`, `json`, `molang`, `project`, `debugger`
+- **subcategory** — The specific pack section or feature area (e.g., `entity`, `block`, `mcfunction`)
+- **type** — The kind of issue (e.g., `missing`, `invalid`, `deprecated`)
+- **detail** — Optional further specificity (e.g., `components`, `event`)
+
+## Severity Levels
+
+| Severity | Description |
+|---|---|
+| **error** | The content is invalid and will not work correctly in Minecraft |
+| **warning** | The content uses deprecated or discouraged features that may stop working |
+| **info** | Informational notice about the content |
+| **hint** | A suggestion for improvement (e.g., performance optimizations) |

+# Biome - Climate - Particles
+
+`behaviorpack.biome.components.climate.particles`
+
+**Severity:** warning
+
+## Description
+
+The particle capability inside the `minecraft:climate` biome component has been moved to `client_biome.json` files. Defining particles in the server-side biome definition no longer has any effect.
+
+## What triggers this error
+
+This warning is triggered when the language server detects a `particles` property inside the `minecraft:climate` component of a behavior pack biome definition. Since Minecraft moved ambient particle effects to client-side biome definitions, this server-side property is no longer processed.
+
+## Example
+
+The following biome definition uses the deprecated climate particles property:
+
+```jsonc
+{
+  "format_version": "1.13.0",
+  "minecraft:biome": {
+    "description": {
+      "identifier": "example:my_biome"
+    },
+    "components": {
+      "minecraft:climate": {
+        "temperature": 0.8,
+        "downfall": 0.4,
+        "particles": [
+          {
+            "id": "minecraft:ambient_block_chance",
+            "chance": 0.01
+          }
+        ]
+      }
+    }
+  }
+}
+```
+
+## How to fix
+
+Move the particle definition to the client-side `client_biome.json` file. Create or update the corresponding file in your resource pack:
+
+```jsonc
+// resource_pack/biomes_client/example:my_biome.json
+{
+  "format_version": "1.21.0",
+  "minecraft:client_biome": {
+    "description": {
+      "identifier": "example:my_biome"
+    },
+    "components": {
+      "minecraft:ambient_particles": {
+        "particle": {
+          "id": "minecraft:ambient_block_chance",
+          "chance": 0.01
+        }
+      }
+    }
+  }
+}
+```
+
+Remove the `particles` property from the `minecraft:climate` component in your behavior pack biome file.

+# Biome - Components - Deprecated
+
+`behaviorpack.biome.components.deprecated`
+
+**Severity:** warning
+
+## Description
+
+A deprecated biome component is being used in this biome definition. These components have been removed or replaced in newer versions of Minecraft Bedrock and may not work correctly.
+
+## What triggers this error
+
+This error is triggered when the language server detects a known deprecated biome component. Known deprecated components include:
+
+- `minecraft:surface_parameters` — replaced by `minecraft:surface_builder`
+- `minecraft:frozen_ocean_surface` — replaced by `minecraft:surface_builder`
+- `minecraft:mesa_surface` — replaced by `minecraft:surface_builder`
+- `minecraft:overworld_generation_rules` — superseded by newer world generation APIs
+- `minecraft:climate` (partially deprecated features)
+
+## Example
+
+The following biome definition uses a deprecated surface component:
+
+```jsonc
+{
+  "format_version": "1.13.0",
+  "minecraft:biome": {
+    "description": {
+      "identifier": "example:my_biome"
+    },
+    "components": {
+      "minecraft:surface_parameters": {
+        "top_material": "minecraft:grass",
+        "mid_material": "minecraft:dirt",
+        "sea_floor_material": "minecraft:gravel",
+        "foundation_material": "minecraft:stone",
+        "sea_material": "minecraft:water"
+      }
+    }
+  }
+}
+```
+
+## How to fix
+
+Replace deprecated surface parameter components with `minecraft:surface_builder`:
+
+```jsonc
+{
+  "format_version": "1.21.0",
+  "minecraft:biome": {
+    "description": {
+      "identifier": "example:my_biome"
+    },
+    "components": {
+      "minecraft:surface_builder": {
+        "identifier": "minecraft:default_surface_builder",
+        "top_material": "minecraft:grass",
+        "mid_material": "minecraft:dirt",
+        "sea_floor_material": "minecraft:gravel",
+        "foundation_material": "minecraft:stone",
+        "sea_material": "minecraft:water"
+      }
+    }
+  }
+}
+```
+

+# Biome - Pre 1.17 Component
+
+`behaviorpack.biome.components.pre_1.17_component`
+
+**Severity:** warning
+
+## Description
+
+This biome definition uses a component that predates the Caves and Cliffs update (1.17). These pre-1.17 biome components do not work with custom biomes created using behavior packs and will be silently ignored.
+
+## What triggers this error
+
+This warning is triggered when the language server detects biome components that were part of the legacy biome system used before the Caves and Cliffs update. These components were designed for the old world generation pipeline and are incompatible with the custom biome API available to content creators.
+
+Examples of affected components include older overworld generation components that relied on the pre-1.17 world generation system.
+
+## Example
+
+The following biome definition uses a legacy component that is incompatible with custom biomes:
+
+```jsonc
+{
+  "format_version": "1.13.0",
+  "minecraft:biome": {
+    "description": {
+      "identifier": "example:my_biome"
+    },
+    "components": {
+      "minecraft:overworld_generation_rules": {
+        "hills_transformation": "jungle_hills",
+        "shore_transformation": "beach",
+        "generate_for_climates": [
+          ["cold", 1]
+        ]
+      }
+    }
+  }
+}
+```
+
+## How to fix
+
+Remove or replace the pre-1.17 component with a modern equivalent. For world generation, refer to the current Minecraft Bedrock [custom biomes documentation](https://learn.microsoft.com/en-us/minecraft/creator/documents/custombiomes) to understand which components are supported for add-on biomes.
+
+Note that not all biome features available to vanilla Minecraft biomes can be replicated through the custom biome API. Some features are restricted to built-in biomes only.

+# Biome - Replace Biomes - Multiple Dimensions
+
+`behaviorpack.biome.components.replace_biomes.multiple_dimensions`
+
+**Severity:** warning
+
+## Description
+
+This biome definition attempts to replace biomes in both the Overworld and the Nether simultaneously. Using biome replacement for multiple dimensions in a single biome definition is discouraged as it can cause unexpected behavior and conflicts.
+
+## What triggers this error
+
+This warning is triggered when the language server detects that a biome's replace biomes component targets more than one dimension. Each biome replacement should target a single dimension to avoid conflicts and ensure predictable behavior.
+
+## Example
+
+The following biome definition incorrectly targets multiple dimensions:
+
+```jsonc
+{
+  "format_version": "1.16.0",
+  "minecraft:biome": {
+    "description": {
+      "identifier": "example:my_custom_biome"
+    },
+    "components": {
+      "minecraft:overworld_height": {
+        "noise_params": [0, 0.1]
+      },
+      "minecraft:nether_generation_rules": {
+        "target_percentage": 0.1
+      }
+    }
+  }
+}
+```
+
+## How to fix
+
+Split the biome definition into separate files, one per dimension:
+
+```jsonc
+// example:my_custom_biome_overworld.json
+{
+  "format_version": "1.16.0",
+  "minecraft:biome": {
+    "description": {
+      "identifier": "example:my_custom_biome_overworld"
+    },
+    "components": {
+      "minecraft:overworld_height": {
+        "noise_params": [0, 0.1]
+      }
+    }
+  }
+}
+```
+
+```jsonc
+// example:my_custom_biome_nether.json
+{
+  "format_version": "1.16.0",
+  "minecraft:biome": {
+    "description": {
+      "identifier": "example:my_custom_biome_nether"
+    },
+    "components": {
