Hi. I've built a couple handfuls of challenge checkers with the Project-GC tools, and I recall running into very much the same issue when I did my first polygon-based checker.
The format you want is the one that's hardcoded into the "GenericPolygonChecker" code that lillfiluren authored. What PGC Support will tell you is to provide them a file in the format, and that they'll eventually post it on their servers so you can just tag GenericPolygonChecker and pass in your filename. I've waited weeks and gotten nowhere on that tactic. And because I'm the impatient type, I usually make a copy of GenericPolygonChecker, and plug my own data into it... run it, test it, verify it, list it... and THEN send a note to PGC Support. If and when they move the file up, I go back and rebuild the checker as a tag to the generic script.
The specific JSON format you need is like this:
local myChallenge_polygons = {
["Three Finger Jack"] = { polypoints = {{ {44.375,-121.875},{44.375,-121.75},{44.5,-121.75},{44.5,-121.875},{44.375,-121.875}} }},
["Black Butte"] = { polypoints = {{ {44.375,-121.75},{44.375,-121.625},{44.5,-121.625},{44.5,-121.75},{44.375,-121.75}} }},
["Little Squaw Back"] = { polypoints = {{ {44.375,-121.625},{44.375,-121.5},{44.5,-121.5},{44.5,-121.625},{44.375,-121.625}} }},
... etc ...
}
If you need more info, feel free to ping me -- I'm not a very frequent browser of this forum, so an email/message would be fastest.
