Landgen usage (Worms 2)

(Up to Game logic)

Landgen (short for Land Generator) is the command line program that generates land files for Worms 2. It's located at "%Worms_2_Install_Dir%\Binaries\Landgen.exe". Landgen is executed by frontend, which sets "Default Dir" for Landgen to "Worms 2 Install Dir". This means the paths passed to Landgen by frontend are relative to "Install Dir", not "Binaries\".

Landgen is used to create:

• Thumbnails for Terrain Editor

Command Line: Landgen.exe /thumbnail Path\name_of_generated_thumbnail Land_base_line Base_line_noise Noise_randomization

Example : Landgen.exe /thumbnail levels\thumbs.dat 444831613 24 54

• Previews - 1:1 terrain data file that is used in manual terrain editing.

Command Line: Landgen.exe /preview Path\name_of_generated_preview Land_base_line Base_line_noise Noise_randomization

Example : Landgen.exe /preview levels\preview.dat -1891240261 95 29

• Land that is used for game and land preview in Terrain Editor

Command Line: Landgen.exe /generate Path\name_of_generated_land Path_to_level_sprites_dir Path_to_water_sprites_dir Land_base_line Object_code Objects_count Base_line_noise Noise_randomization

Example : Landgen.exe /generate data\land.dat .\data\level\FARM .\data\water\Blue 1765502980 24323 50 4 40

• Land for game and land preview generated from edited terrain

Command Line: Landgen.exe /grafitti Path\name_of_generated_land Path_to_edited_land_data Path_to_level_sprites_dir Path_to_water_sprites_dir Land_type Object_code Objects_count

Example : Landgen.exe /grafitti data\land.dat levels\grafitti.dat .\data\level\SNOW .\data\water\Blue 1 18688 50

Land_base_line 

random signed 32-bit integer, used for land randomization, first 8 hexadecimal digits of Terrain Code, never equals to 0

Base_line_noise 

random number, values 0-100, used for land randomization, 9-10 hex-digits of Terrain Code

Noise_randomization 

random number, values 0-100, used for land randomization, 11-12 hex-digits of Terrain Code

For Line Noise and Noise randomization hex values greater than 100 recalculates as [HexVal MOD 100].

Example : Terrain Code = 2E3C132D6466 -> Land_base_line = [2E3C132D] = 775689005; Base_line_noise = [64] = 100; Noise_randomization = [66] = [102 MOD 100] = 2

Object_code 

random number up to 11 digits or more, used for level object's sprites randomization

Random numbers are generator seeds, which means same numbers generate same terrain. Still researching how this numbers change affects generated terrain.

Objects_count 

set how many object appears on terrain, values 0-100, by default = 50

Land_type 

0 = Open, 1 = Cavern

---

There can be more. Research continues.
