FairLoc short for FairLocations are some functions in RMS scripting which are used to place e.g. Settlements fairly.
Here a Quote from MythicFreaks Code Reference: "These special commands are designed to place critical resources, such as Settlements and sometimes Gold Mines. They are expensive and slow, so should not be used for many objects, but can insure that objects that "must place" are present on a map."
The FairLocs are probably threated differently by the code to ensure they are being placed. That we cannot replicate, but I was more interested in the fair positioning, like placing forward or backward TCs.. x.x
If it is for guaranteeing placement is there a way to detect failure and try again in a different position until succeed? I had a feeling there was some sort of way to detect placement failure but I may be wrong.
