=================Instructions================ Welcome to my black hole simulator! Use the W, A, S, D keys to control the black hole, (use joystick if mobile,) then you can tap around the screen to create some stars, set the GROW variable (up, left) to 1 to let the black hole grow and set it to 0 to keep it its size. the STAR TYPE variable slider, (down left, above the JOYSTICK? variable slider,) can go from 1 to 6, each mode creating a different star each with different densities. when the screen is clicked: red dwarf; main sequence; subgiant; red giant; white dwarf; and neutron star. WARNING: more star's mean's more lag. Change the SPEED variable to edit the speed of the black hole from 0.1 to 0.99 (up, left, below the GROW? variable), but only when you're using a keyboard, and press the J key to show/hide a joystick (down, left), or move the slider. Play on Turbowarp for better pen quality and infinite particles: https://turbowarp.org/1187170419?hqpen&clones=Infinity# =================Update Log================ 6/11/2025: Initial release. 6/21/2025: Added a MASS variable (down, left, above the JOYSTICK? variable) reporter to show how massive the black hole is, then added a SPEED variable reporter to control the speed of the black hole, next changing some code so a particles velocity depends on the black hole's size and finally added a JOYSTICK? variable reporter to be able to turn on/off a joystick. 6/24/2025: Added the STAR TYPE variable to change the color, and density. Also made the stars move like there's a camera, and finally renamed the particles stars.
This is my first mobile project! Thanks to Griff-patch for the tutorial of the joystick, although I only followed part of it: https://www.youtube.com/watch?v=9TK8x2nSMPI# Also, thanks to Kurzgrast: In a Nutshell for the style of the black hole.
