the BLUE alliance has a green over pink trailer vision target. However, I’m not sure that the GetAlliance.vi searches out the vision target. I was under the impression that it did not, however, this could be an eror on my part. The numbers (1,2,3) correspond to the location of the team members in their alliance base. I believe 1 is closest to the fueling station that is adjacent and same color as the alliance base. There is a diagram on the first website I believe.
Hope this helps in some way.
