Sometimes it is worth stepping back from work related projects and focus on something that you find more fun. Over the last month or so, I started to work on a couple of these fun little projects.
The project I’m going to show here is a sand simulator. There is a short animated gif shown below.
This project came from watching a Youtube video where someone explained creating their own version of a sand simulation. I used many of their ideas, but implemented them in my own ways. What you see above is the current version of what I have been playing with. The app includes 8 different types of particles that interact with each other in different ways. Sand will pile up like sand does. Water attempts to level itself. Snow and ice pile up in their own ways and fire will turn water, ice or snow into steam that will rise off the screen.
There were many interesting techniques used to make this all happen with the main movement based on Cellular Automata theories. Each particles moves by looking at it’s surrounding neighbors and then decided how to move. For the most part, they only care about the 8 locations directly surrounding them. As simple as that sounds, it allows for some interesting and occasionally surprising interactions.
Doing this project let me work through some interesting programming issues, while at the same time giving me something fun to play with. A majority of the code fits in around 400 lines and it does everything you can see above.
So, if you find yourself stuck – step back and find a small project that appeals to you and work on that. It will not only better your programming skills, but it will also allow your brain to reset before you return to your actual work.
