A simple interactive physics simulation with a ball.
End goal is to have the ball bounce around the form window smoothly.
FormMain.cs
BallPhysics.cs
Ball.cs
Got all the skeleton in place for the form layout and appearance.
Got a feel for events such as MouseClick and got the text to successfully disappear when the mouse is held down.
Later I would realize that I can just specify that the text label is not allowed to have focus, and that will make it disappear when I click on it.
Got the ball to draw upon clicking the mouse, although I didn't bother getting it centered just yet. Focusing on small steps.
This is when I figured out the setting to make elements non-focusable.
As you can see, the ball correctly updates position even if I click inside it's drawbox.
Enlarged the ball for better visibility.
The ball now centers on the mouse pointer.
Implemented ball physics.
As you can see, I was having some trouble with absolute/relative mouse coordinates. Relative coordinates are not always available depending on where in the scope you try to reference them.
Ball position is now consistent with release point. I figured out how to deal with the relative/absolute mouse position stuff.
Ball physics are working ok, but not as smooth as I would like. Not sure how complicated it's going to be to fix. I'm running the physics loop at a time step of 7 milliseconds, so maybe if I increase that to be closer to 60 Hz rather than my monitor's 144 Hz.
Next step is implementing collision with the form walls.
