# Custom biome ## Create the file To create a custom biome, the first command to run is : ``` /scustom biome ``` This generates a new file named `` located in the `/plugins/Stratos/customization/biome/` folder. In this file, you can edit everything including terrain noise, areas, blocks and decorations for the biome. ## Terrain noise ### Amplitude and frequency In the context of terrain generation, **frequency** refers to the number of peaks and valleys in a given area, while **amplitude** refers to the height of those peaks and valleys. A terrain with high **frequency** will have many small peaks and valleys, while a terrain with low **frequency** will have fewer, but larger peaks and valleys. **Amplitude**, on the other hand, determines how high or low the peaks and valleys are. A terrain with high **amplitude** will have very tall peaks and deep valleys, while a terrain with low **amplitude** will have smaller peaks and shallower valleys. These two parameters can be adjusted to create different types of terrain, from rugged mountains to rolling hills. ### Define noise and frequency In Stratos, modify the **terrain\_noise** value to change frequency and amplitude (you can add as many noises as you want to get the desired result) ### Example : ``` terrain_noise: - ==: SConfigTerrainNoise frequency: 0.2 amplitude: 0.6 - ==: SConfigTerrainNoise frequency: 0.5 amplitude: 0.4 ``` {% hint style="info" %} Noises you define here are added together to compute the final terrain {% endhint %} ## Minimum height The **minimum\_height** value defines the elevation of the world. Increase it to have to world higher. ## Terrain zones Terrain zones define the multiple areas you can create in a biome, each area can have its own blocks. The value to modify is **terrain\_zones**.

Multiple areas in Mushroom biome

For each area paste a SConfigZone value **Example :** ``` - ==: SConfigZone probability: 0.4 # Sum of materials probabilities must be 1 materials: - ==: SConfigMaterial material: GRASS_BLOCK probability: 0.3 - ==: SConfigMaterial material: GRAY_WOOL probability: 0.4 - ==: SConfigMaterial material: GREEN_WOOL probability: 0.3 decorations: - ==: SConfigDecoration material: GRASS_BLOCK probability: 0.05 - ==: SConfigDecoration material: GREEN_WOOL probability: 0.09 ``` The **materials** are the blocks placed at the terrain level. The **decorations** are placed one block higher. ## Add your biome into the world configuration To add the biome you created into the world configuration (either per-world or main configuration), add these lines into the **biomes** property. ``` - ==: SCustomBiome biome: centerX: 0.0 centerY: 0.0 lavaRiver: false spigotBiome: PLAINS tree_probability: 0.8 ``` Properties are the same as SBiome with two new properties : * **lavaRiver** : true if you want to have lava rivers in your biome, false otherwise * **spigotBiome** : the name of the [spigot Biome](https://hub.spigotmc.org/javadocs/spigot/org/bukkit/block/Biome.html) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://alex-plugins.gitbook.io/stratos/customization/custom-biome.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
