This idea seems similar to screeps, robocode, battle-code, and to a lesser extent, Neural MMO. Source: over 1 year ago

Looks cool! Reminds me of robocode. Source: over 1 year ago

I found https://robocode.sourceforge.io/ in Java, https://screeps.com/ in JavaScript (WASM from Golang seems not to work), and https://leekwars.com/ had its own language…. Source: about 2 years ago

You had to write the intelligence of a robot/tank in a C-like language of these game development software. The bottom line is two of these programs competed against each other. If I remember correctly these battles took place in a recurring tournament and you could win a license of the game developement software, or maybe nothing. The only one I found in a 2-minute search that is similar to this is Robocode... Source: about 2 years ago

One of the first incantations of this idea that I encountered, when I had just started working at my first corporate job back in the day, was Robocode ( https://robocode.sourceforge.io/ ) - it was great fun, and I see it's still going. - Source: Hacker News / about 2 years ago

CodeGym is one of my favorite Core Java online courses. It’s very practice-oriented. There are more than 1,200 coding tasks with code validations and tips to help a student solve tasks. Also, it contains short lectures that cover all core Java topics (except lambdas, for the moment). - Source: dev.to / over 1 year ago

I started learning it from their russian version (this course was originally written in Russian) but if English version is as good as Russian, then it's probably the best way to start learning java, as they have probably few thousands of exercises https://codegym.cc/. Source: over 1 year ago

If you want to take a slightly longer, but imo easier path. I went from learning coding using https://codegym.cc/ to being a Software Quality Assurance Automation Engineer (current) and will eventually transition to BE Dev on my company's dime: At the last 3 companies I've been a QA Engineer at, there's always been a pipeline from QA -> Dev that the company is willing to work with you on.

Https://codegym.cc/ - my preferred site for interactive learning. Source: about 2 years ago

You could try something interactive CodeCademy to get them started, or something game-based like Code Combat or Code Gym. Alternatively, try finding any local groups or classes aimed at teens. Source: about 2 years ago
