Earlier quoted context omitted.

Facebook has a patent for using gyroscope data in conjunction with location to know who you are facing with other people around to enhance friend suggestions. You can also determine things like health and other physical characteristics, similar to gait detection.

...wait, how do you get orientation relative to things around you (rather than just your own previous orientation and gravity) from just gyro/accelerometer data + location? If you do have some source of absolute orientation, like a compass, surely you just use that and don't need the gyro.

Agreed. There are so many JS projects these days composed of a dozen abstraction layers and barely-used libraries all mixed together and spread out across multiple files with an insanely complex "build system" on top, that it's very refreshing to see simple, self-contained JS.

My brain hurts just imagining this.

That's cool, also similar idea to a game I made some time ago for a lisp game jam https://orbaruk.github.io/ https://github.com/OrBaruk/squares-lgj

Your game is faster paced, I like it. One issue I noticed is that the red blocks can spawn right in front of your block, making it nearly impossible to avoid. Rage quit inevitable.

Hasn’t been mentioned before: try this on a phone. It uses the gyroscope for control and it quickly becomes second nature to balance/guide the square around the screen. Also a very nice and rewarding discovery process, as it starts out with squares speeding by, until you realize it’s the tilt of your phone that is causing it. Congrats, super fun!

Snowcrash mode :) (In console): setInterval(function() { hero.x = powerUp.x; hero.y = powerUp.y; }, 50); setInterval(function() { hero.x = reward.x; hero.y = reward.y; }, 100);

  maxScore = 0;
  setInterval( function() {
  	if (score > maxScore) {
  		maxScore = score;
  	}
  	if (distance(hero.y, hero.x, ennemi.y, ennemi.x)  PowerUpspawnRate) {
  		hero.y += (powerUp.y - hero.y) * speedLimit / distance(hero.y, hero.x, powerUp.y, powerUp.x);
  		hero.x += (powerUp.x - hero.x) * speedLimit/ distance(hero.y, hero.x, powerUp.y, powerUp.x);
  	} else {
  		hero.y += (reward.y - hero.y) * speedLimit / distance(hero.y, hero.x, reward.y, reward.x);
  		hero.x += (reward.x - hero.x) * speedLimit/ distance(hero.y, hero.x, reward.y, reward.x);
  	}
  }, 25);
