Hi all, I'm looking for an algorithm which makes shoots my zombie from one location towards the other, in a parabolic matter. I found this thread on Bukkit, but the algorithm seems to go incorrect as soon as you start adjusting the height. I had to also adjust the gravity, as the given one doesn't seem to be correct. The height in my case is variable; it can change dynamically since the entity walks around in an area at different Y levels. So I'm looking for an algorithm that calculates a parabolic velocity from A to B, with a variable height, that's consistently accurate. I'm pretty terrible at math, so would appreciate small comments explaining some code samples. Anyone that can help?
