This makes it so that only inputs between 1 and 255 inclusive will be accepted. Otherwise, the command has no effect. This is because the text case is stored as one byte in a string, and a value of zero would be the null terminator. We also want to minimize potential weirdness with integer wrapping if we accept inputs from outside those bounds. While the textcase variable as used throughout the codebase is plain unqualified `char` (which, unlike other integers, exists in a quantum superposition of being signed and unsigned depending on compiler, machine, and various other stuff) and so there still might be issues there, we definitely don't want anything higher than 255.
This is the source code to VVVVVV, the 2010 indie game by Terry Cavanagh, with music by Magnus Pålsson. You can read the announcement of the source code release on Terry's blog!
The source code for the desktop version is in this folder.
VVVVVV is still commerically available at thelettervsixtim.es if you'd like to support it, but you are completely free to compile the game for your own personal use. If you're interested in distributing a compiled version of the game, see LICENSE.md for more information.
Discussion about VVVVVV updates mainly happens on the "unofficial" VVVVVV discord, in the vvvvvv-code channel.
