Well thanks, but I was rather hoping for some function that instantly tells me, whether a certain actor can reach a certain destination. Think of an RTS game where you order your units to move to the location you clicked on. The only way to perform this check that I currently know of is to order them to move there right away using MoveToLocation(…) and check the result. But then I have already sent them there, and I don’t always want to do that, but instead have them finish whatever important stuff they may already be doing first. So I’d rather just check if the order is valid, but not necessarily carry it out immediately.
