This project grows out of my desire to learn Kotlin and Processing simultaneously. It is also an experiment to gain access to Processing's core library (all those graphics functions) without using its IDE. As it turned out, Processing and Kotlin can work together quite seamlessly.
All programs are small and stand-alone. You need Java 8 and Gradle 4.4 to build them:
gradle classesto compilegradle runto see it
In chronological order:
Model gravity and bouncing.
Follow a fixed point on a rolling circle. Some beautiful curves are traced out.
Use arrow keys to adjust the launching angle and speed, use spacebar to launch. Model gravity and wind resistance.
Experiment with JBox2D. Can the house stop the boulders?
