Thread: Repeated warnings and sys.txt editing.

You are correct; the warning distance is triggered by the "warn_distances=" command, and the repeat distance setting works exactly as you describe in your second post. You can have an overall setting in the [warning] section of sys.txt or you can have individual settings for each speedcam type in separate [speedcam_category:xx] sections.

Each pair of numbers in the "warn_distances=" string (in your case "120:1000,90:690,70:690,50:690,30:540") is actual road speed to the left of the colon and warning distance to the right,

How it works:
The first setting in your string is 30:540 - because 30 is the lowest speed listed, you will not receive a warning when your actual road speed is less than 30 km/h.
At 30 km/h or faster, the 30:540 rule takes effect and you will get the first warning 540 metres from the recorded position of the hazard.
When your road speed increase to 50 or more the 50:690 rule takes effect and you now get the first warning 690 m before the hazard.
The next two rules in your example, 70:690 and 90:690, have no effect because they specify the same warning distance as the 50:690
Finally at speeds of 120 km/h or greater, the first warning will be 1000 m from the hazard.
I have no idea if it is important in which order the rules are written , but in every example I have seen the highest speed is always written first

I'm finding it difficult to write all this down clearly so i hope what i have said makes some sense to you.

Just a note about testing; be aware that one or more of the .ini files within Primo may also contain some of these settings. If you don't override these in sys.txt they will continue to be applied so its worth extracting all the .ini files from data.zip to see whats lurking in them. Usual offender is data.zip\project_config\igo9.ini but there can be others.

I too am still interested to know the use of "speedcam_snap_distance", "min_frc", and the assorted "skin_..." commands so if any other users reading this can clarify, please feel free to contribute your knowledge.
