This has been added to SPS-RS3, so no need to copy into your scripts
A function that checks whether you are inside a polygon. This is more customisable than using a simple pointInBox. The polygon can have 3+ vertices, as demonstrated with the SPS Path Generator:
Just declare your polygon as a TPA, exactly the same way you do when making a SPS path (you can just copy the TPA from the path generator):
Some test code would look something like:
