Crafting Your Realm: World Generation Logic
In the Terraria engine, world parameters are technically static once the generation sequence concludes. This means you cannot expand a “Small” world into a “Large” world or transition from “Classic” to “Master” mode after the world file (.wld) has been created. These critical variables must be defined within your configuration registry before the server initializes its first world instance. This guide walk you through the technical configuration of your world and the procedure for forcing a regeneration.

Technical Configuration (serverconfig.txt)
You can define these variables directly within the serverconfig.txt file or use the Startup tab in the FREAKHOSTING Game Panel.
1. World Size Calibration (autocreate)
This parameter dictates the total horizontal and vertical dimensions of your map.
1(Small): Optimized for singleplayer or 1-2 survivors.2(Medium): A balanced environment for small cooperative groups.3(Large): Highly Recommended for public community servers (4+ players). A large world ensures sufficient resource distribution and biome diversity for every participant.
2. Difficulty Tiers (difficulty)
Adjust the survival intensity and loot quality by modifying the following modes:
| Mode ID | Name | Mechanical Impact |
|---|---|---|
0 | Classic | Standard baseline gameplay and mechanics. |
1 | Expert | Scaled boss health, increased drop rates, and unique Treasure Bags. |
2 | Master | Extreme tactical challenge, exclusive relics, and rare mount drops. |
3 | Journey | Accessible mode featuring research and duplication capabilities. |
Procedure for World Regeneration
If you have already initialized a world and wish to modify these settings, you must programmatically force the engine to regenerate the terrain.Initialize Maintenance
Log in to the Game Panel and Stop your server.
Update Configurations
Modify the
autocreate and difficulty variables in your Startup settings or serverconfig.txt to reflect your new desired state.Purge Legacy Data
