Reseting scenario

[heavy garden]

I have an array of object and i would like to know how can i reset their position. Or better, delete those objects and create new ones and start everything from the beggining. Is this possible?

When the scene starts, save the original location to the userData. And when a reset occurs, change their location to originPosition.

Deletion and creation may cause performance problems. You can use visible property instead.

how do i save that thing?

const pos1 = new THREE.Vector2(0, 0);
const pos2 = new THREE.Vector2(0, -200);
const pos3 = new THREE.Vector2(0, 200);

const vel1 = new THREE.Vector2(0, 0);
const vel2 = new THREE.Vector2(-2, 0);
const vel3 = new THREE.Vector2(2, 0);

// Celestial Bodies initialization
const bodies = [
  new CelestialBody(pos1, vel1, 1000, "white", scene),
  new CelestialBody(pos2, vel2, 100, "red", scene),
  new CelestialBody(pos3, vel3, 100, "teal", scene),
];

  resetButton.addEventListener("click", () => {
    cancelAnimationFrame(simulationId);
    bodies.forEach((body) => {
      scene.remove(body.mesh);
    });
    bodies.length = 0;
    bodies.push(
      new CelestialBody(pos1, vel1, 1000, "white", scene),
      new CelestialBody(pos2, vel2, 100, "red", scene),
      new CelestialBody(pos3, vel3, 100, "teal", scene)
    );
    paused = true;
    startButton.textContent = "Resume Simulation";
  });```

I would like to do this, but it isnt working

like, object keep moving from where they were

should i just better set each body to its original position?

@sinful oar

maybe i need to remove the body and not the mesh and add them back?

can you teach me about CelestialBody? If CelestialBody is a class, you just copy position of pos1, pos2, pos3.
