I first started the how to make Java games series to solve a bunch of problems. Many people in the forums are posting extremely complicated ways to rotate polygons in Java for example. It is very easy to rotate polygons!

I also saw many people struggle with other calculations like:

1. Finding the length and angle of a line between vectors
2. Calculate the points of a rotating polygon
3. Calculate the area of irregular polygons
4. Find the center points of an irregular polygon
5. Repeat keyboard clicks if the user holds down a key

Much, much more….
