Fix a game that shows nothing once it sits in a folder on the web

A game can run perfectly on your computer and show a blank screen when put on a hosting page that serves it from a sub-address. The cause is how file paths are written. This entry finds the risky paths and rewrites them so they work wherever the game sits.

Why this works

A path that starts from the top of the site means the top of the whole website, not of your game. Writing each path starting from the folder of the file that uses it keeps the game working wherever it is placed, since the pieces always move together.

When not to use it

Needless if you host the game on its own address at the top of a site, where paths from the top are correct. It also does not help when the host rewrites addresses itself or serves files from a separate server; then follow the host's own instructions.
