The Quadrants.txt file determines how the systems are arranged on the Galaxy Map, and how many of each type of system is in a particular map.
There can be as many types of quadrants in the file as you want. We shall take a look at part of the Mid-Life quadrant:
Name := Mid-Life Description := Standard middle age section of the galaxy. Min Dist Between Systems := 1 System Placement := Random Max Warp Points per Sys := 5 Min Angle Between WP := 60 Number of System Types := 39 Type 1 Name := Standard 1 Type 1 Chance := 240 Type 2 Name := Standard 2 Type 2 Chance := 237 Type 3 Name := Standard 3 Type 3 Chance := 195
The rest of it is just more system types, and so is repetitive.
Name := Mid-Life Description := Standard middle age section of the galaxy.
The name is what is displayed when selecting a quadrant type when creating a game. The Description is never displayed anywhere.
Min Dist Between Systems := 1
This is the minimum number of system squares on the Galaxy Map that must be between each system. At 1, this means that no 2 systems can be in directly adjacent squares.
System Placement := Random
This determines how the systems are set up on the Map. The possible values are: Random, Clusters, Spiral, Diffuse, Grid. Random places the systems in a chaotic fashion. Cluster makes the systems be placed in 12 areas on the map. The systems are concentrated in these 12 groups. The groups are organized with 4 groups in 3 rows on the Map. Spiral makes the systems organized into a spiral-type pattern. Diffuse places the systems in a more organized fashion than Random. Grid sets the systems into a rigid gridded pattern.
Max Warp Points per Sys := 5
This determines the maximum warp points that can be in a system. This can be overridden to ensure connectivity.
Min Angle Between WP := 60
This determines the minimum angle that the warp lines coming out of a system on the Galaxy Map can make. This can be overridden to ensure connectivity.
Number of System Types := 39
This determines how many system types can be in the galaxy.
Type 1 Name := Standard 1 Type 1 Chance := 240 Type 2 Name := Standard 2 Type 2 Chance := 237 Type 3 Name := Standard 3 Type 3 Chance := 195
These lines determines which system types can be present in the quadrant, and what chance they have of appearing. The Chances are in tenths of a percent. They should total up to 1000 (100%) for the quadrant. However, do not worry to much about getting it at exactly 1000. If the total is 1010, 990, or something like that, SEIV will compensate and readjust the values when it generates maps with that quadrant.
