Warcraft 3 modding community led me to take Computer Science course and I am really thankful for it. I was like 11 or 12 when I created my first spell and posted it on here (dont look it up, its really bad) and now I'm back for reforged.
I'm using Jass now and created a physics and missile system for my map and I'm wondering if my code can further be optimized
As you can see, my physics system is somehow similar to Quillnez rigid body physics except that it doesn't work in upward slope (For balance purposes)
