Random Generators

Here are a bunch of random generators for all kinds of things like Dungeons & Dragons, World of Warcraft, and even some silly stuff, like Survivor.

Star System Generator

PLEASE NOTE: The sheer amount of information here makes it impossible to format the system generator for small screens. Please use this on a medium or higher screen for best display results.

I've been involved in star system generation code for quite a while. There was one in particular that offered everything I needed: Aina's Star Generator.

Unfortunately Aina stopped updating the code over twenty years ago and can no longer be reached. He published his code base online back in the day so others could use and improve it.

Here we are in the here and now. I've updated his code to work with php and have made quite a number of modifications. The goal is to make a few tweaks here and there and test out the random generator in a gravity simulator like Universe Sandbox 2 to see just how viable these star systems are.

temperatures: planet temperatures are seriously out of whack. I've left them in until I can figure out the problem.
