The position of the unit is interpolated depending on its speed and movement direction.

Due to interpolation the position might not be accurate, but it's updated frequently, resulting in a smooth motion.

  1. isPlayer _entity does not return true immediately. Once the entity has become a player, it is transferred to the client.
  2. 2.0 2.1 Note in single player that while the environment is Scheduled (canSuspend returns true), the engine seems to wait until the script is done executing, essentially behaving similarly to an Unscheduled environment - infinite loops will freeze the game, uiSleep may pause the game for up to ~20s (postInit), waitUntil can cause catastrophic issues, etc.
  3. player is not available immediately.
