I meant would there be a faster way to cache the dangers of points on the secondary wave. For the first wave paths, I use an array and a quicksort that takes an array of dangers and returns an array of the order of the dangers, which was the fastest way I could think of doing this. I don't know much about hashmaps so I was wondering if there would be a faster way to store about 400 points and thenk check if any of them were identical to another point, on thinking it over, the points would probably be added in increasing or decreasing order of X and Y so I may be able to keep an arraylist sorted without much overhead.
