For a while now I’ve been thinking about the barriers preventing me from doing cooler, more awesome visuals and interactions. I’ve come to the conclusion that what is missing is rudimentary trigonomic and geometric principles in my development approaches. So, I am going to do something about that.
My first step is to conjure up all those things I learned (or should have learned) in high school/early college that I thought I would never use again in my life. I started with these two:
Using these you can easily find distances between two DisplayObjects and the degrees to rotate a DisplayObject to point at another DisplayObejct. Basically you are creating imaginary triangles and using math/code to get the properties of that triangle.
Here is what I came up with. The triangle (movable by keyboard) will always point at the reticle/crosshair (which follows the cursor). Click to shoot. I now have the beginings of a Geometry Wars style game. Next step is collision detection and then fractals.
