characterState method

@override void characterState(int character, CharacterState3D out)

Reads character's state into out without moving it; a dead character reads as zeros, in the air.

Implementation

@override
void characterState(int character, CharacterState3D out) {
  final c = characters[character];
  if (c == null) {
    _clearState(out);
    return;
  }
  out.position.setFrom(c.position);
  out.velocity.setFrom(c.velocity);
  out.groundState = c.groundState;
  out.groundBody = c.groundBody;
  final ground = bodies[c.groundBody];
  if (ground != null) {
    out.groundNormal.setValues(0, -1, 0);
    out.groundVelocity.setFrom(ground.linearVelocity);
    out.groundPosition.setValues(c.position.x, ground.minY, c.position.z);
  } else {
    out.groundNormal.setZero();
    out.groundVelocity.setZero();
    out.groundPosition.setZero();
  }
  out.contactCount = ground == null ? 0 : 1;
}
