May/June 2021: More Collisions

+ Obviously, the month of April did not go as planned. I got caught up with a number of tasks that I couldn't handle, + namely, the pill collisions. These, as I discovered, were quite unfeasible and involved a lot of complex maths + that I didn't quite yet understand. They are also unreasonable for game development's sake, so I will ditch that + effort and focus on doing other things. This, of course, is not time entirely wasted, as I now I have a somewhat + better understanding of why ellipses (and by extension ellipsoids, although I am not entirely sure of this). I should + instead try to figure out the intersection using pills, not ellipses. Pills are simply 2D shapes made of a + rectangle in the middle and two half-circles at either ends. This is a far less expensive collision to calculate. +
+ I also failed when it came to getting a good physics collision system going. This stemmed from a general misunderstanding + of moment of inertia and how it can properly be implemented for each shape. I think I am getting a better grip on it now, + however. +
+ And that brings me to May/June. I am combining these two months because I am quite busy in May with family stuff, + and hence won't be able to give my full attention to the project. That being said, as a high-level goal, I hope to + get some more 2D collisions going, and maybe move onto 3D fairly soon. For 3D, I would simply like to get the physics + simulation up and running with simple objects (spheres, cubes, etc.). From there, I want to begin exploring more complex + physics simulation topics like oct-trees, multiple collision resolution, etc. We will see what happens, but I am optimistic, + so long as I stay the course. +
