Here is a follow-up of my completely pointless but incredibly fun side-project to create a retro CRT screen in JS and CSS.
This time I decided to build the hacking minigame from the Fallout game series, which was also the inspiration to start this project in the first place.
Check the full Sandbox for a bigger screen.
The goal of the game is to find the password that is hidden in this garbled mess of characters. You can click a word or move with the arrow keys and use the enter key to confirm. Incorrect guesses will result in a hint indicating how many letters the password has in common with your guess.
Some of the stuff I've learned
- Hexadecimal numbers (
0xffff
) can be used as regular numbers in JS, so you can easily add and subtract them. Seems obvious, just never thought about it. - The CSS
ch
unit (width of one character) combined with a monospace font is super useful for building these kind of text based interfaces, where I want to have a maximum of exactly 80 characters on every line. -
CSS columns is something I rarely use, but works perfectly here. The
column-fill: auto
property was crucial for filling columns one by one, instead of in a balanced manner. - To word-break the passwords and highlight them over multiple lines, I first tried putting a password in a single span with the
word-break: break-all
property, but later switched to one<span>
per character, since that makes the whole thing easier to control using JS and also easier to position. I then assign somedata
attributes to the span to keep track of which word is being clicked and highlighted.
Any cool ideas?
What should I build next? Know any other games with terminal screens like these? Let me know! πππ

This is amazing, Edwin! I loved the hacking mini game from Fallout :D Congratulations!
Yoo this is really cool! I wanted to ask some questions about this in private if you would be willing to I'm a little newer to JavaScript. I wanted to make something similar that is solely text based and I had a bit of trouble trying to reverse engineer what you did. If you wouldn't mind it would be awesome if you could shoot a reply back!
Great work, Edwin! π
Very atmospheric look and feel!
I didn't understand how to win in it though... :)
This is really cool
