Useful Patterns

Scheduling routine for collectible entitites

This is a good approach to prevent iterating over all the collectibles every frame, thus distributing the CPU load.

C#

int schedulePeriod = 10;
foreach (var (entity, c) in f.Unsafe.GetComponentBlockIterator<Collectible>())
{
  if (entity.Index % schedulePeriod == f.Number % schedulePeriod)
  {
    CheckCollectDistance(f, entity, c);
    if (c->TTL <= FP._0)
    {
      f.Destroy(entity);
    }
    c->TTL -= timeMultiplier * schedulePeriod;
  }
}
