Hello all! So I am working on a Java program and we have introduced artificial intelligence to a missile that is hunting a flying aircraft in 2d. The purpose of the program is to compare 3 different guidance systems--pursuit, proportional, and parallel. I am stuck on parallel! We have the aircraft flying at a constant velocity and I am having a hard time understanding where my update should be. Can anyone provide a good link with some detailed info on the subject? I can hardly find anything online! Thanks so much!
