Javacube Seed Finder

Javacube Seed Finder

This tool automates finding Minecraft seeds by entering search parameters with about 100 seeds scanned per second. If you also want to check for ravines, caves, valleys, and encircling tall terrain, consider using MC-SeedLocator (note: it is slower).

Features

• Find structures with biome constraints, height ranges, and minimum amount
• Find any biomes (including island biomes) and biome combinations
• Locate clustered structures (structures next to each other)
• Set biome size requirements

Usage

Set up your parameters in the text box then press scan to start scanning for seeds. When specifying structures or biomes, use their corresponding IDs from the ID References tab. Use -1 for N/A and use 0 for next to biome to find structures in that biome. At least one section is required to be filled.

1. Scanning Options

Parameter	Description
Starting seed	The first seed to start scanning from.
Search radius	Defines how far to search for structures and biomes.
Use spawn	true = search near spawn, false = search anywhere.
Custom x / Custom z	Specific coordinates to scan from (if Use spawn = false).

2. Required Structures

Defines which structures must be present in the world.

Parameter	Description
Structure ID	The ID of the structure (see ID References tab).
Min amount	Minimum number of structures in the search area.
Next to biome	Finds structures near a specific biome (-1 for any biome).
Biome proximity	Distance in blocks from the structure to the biome.
Min height / Max height	Height restrictions for structures.

Example:

1. 5 (min amount: 1, next to biome: 2, biome proximity: 0, min height: -9999, max height: 9999)

3. Structure Clusters

Searches for groups of structures close together.

Parameter	Description
Enabled	Set to true to enable clustering.
Valid structures	List of structure IDs that count toward a valid cluster.
Min cluster distance	Minimum distance between structures to count as a cluster.
Min cluster size	Minimum number of structures required for a valid cluster.

4. Required Biomes

Filters worlds based on the presence of specific biomes.

Parameter	Description
Biome ID	The ID of the required biome.
Min size / Max size	Size requirements for the biome.

Example:

1. 1 (min size: 50, max size: -1)

5. Clustered Biomes

Finds biomes that generate next to each other.

Parameter	Description
Biome list	Group of multiple biomes that must be next to each other.
Min size / Max size	Size restrictions for the clustered biomes.

Example:

1. 185, 1 (min size: -1, max size: -1)

Steps

1. Set up scanning options to define the search area.
2. Add required structures and their conditions.
3. Enable structure clusters if needed.
4. Define required biomes and biome clusters.

Once your parameters are set, press Scan to find the best Minecraft seed for your needs!
