tick method

void tick(double dt)

Advances deadlines and queues expired removals.

Implementation

void tick(double dt) {
  var i = 0;
  while (i < _length) {
    final remaining = _deadlines[i] - dt;
    if (remaining > 0) {
      _deadlines[i] = remaining;
      i++;
      continue;
    }
    final index = _indices[i];
    final generation = _generations[i];
    final type = _types[i]!;
    // Swap-remove first; the row swapped in from the end has not been
    // ticked yet this pass, so continuing at [i] ticks it next.
    _removeRow(i);
    final entity = world.entities.resolve(index);
    if (entity.generation != generation) continue;
    if (!world.stores.isRegistered(type) ||
        !world.stores.require(type).containsIndex(index)) {
      continue;
    }
    world.commands.removeByType(type, entity);
  }
