Punchcard Robots

by tony-li
It's the 1960s, and real nerds prove their mettle in the Robo-Wars! Program your robot in RoboBASIC using punchcards and send it into the arena. Share your RoboBASIC code with others by pasting the encrypted program text into the Comments to see how it fares against other players!

If you're hard core, you can program your punchcards by punching holes in it. If you're a wuss, you can type your code into the input field, and the game will punch the card for you. :-)

I havent done a proper punchcard in a long time. After purchasing c64 and later amiga, punchcards went out of fashion.

A bit of a learning curve but after that it was fun to program your own robot!

Very fun! I think there might be something wonky with angular momentum whenever collisions happen, but it makes for a good show nonetheless. A great take on old tech, and you succeeded in teaching me things about punchcards I never paid attention to in school.

But the real reason we're here: Take on THIS!

the game took a while to load, and I got this error: abort("both async and sync fetching of the wasm failed"). I’m not sure if it’s an issue on my end

The punchcard mechanic looks interesting to play around it but it's confusing and a bit weird even with the manual. Some feedback I'd have is a more practical tutorial that walks the player through how to code a basic robot and let them go from there. The concept is really cool though and I like it a lot!

Needs some time to get it, but very nice idea and great feel to the game.
