How Star Collector works (for kids)

A Three.js game is just 3 things repeating:

1. Scene — the world (lights, ground grid, camera).
2. Things — ship (cone + wings), stars (spinning octahedrons), rocks (red icosahedrons).
3. Loop — every frame: move ship, spin stars, check distances.

if (star.position.distanceTo(ship.position) < 1.1) {
  score += 10; // collect!
}

That’s the whole trick! Distance checks = collisions. Next we’ll learn about requestAnimationFrame and why we use dt (delta time) so the game runs the same speed on any computer.
