Stellar manip and movement in simultaneous game

[douglas]

The information on when stellar manipulation happens currently in the FAQ is incorrect. I have tested it pretty thoroughly and posted my results in the Updated the FAQ thread a little while back. Here are the most relevant parts to this discussion:

A ship's ID number is a unique identifier assigned to ships when they are built. It is not visible to the player. The first available ID is the one assigned. When a ship is destroyed, its ID becomes available again.

Within each day in a turn's movement, ships move in order by ID number. This matters for certain stellar manipulations, seek after orders, and minesweeping. Fleets move all at once when their lowest-ID ship moves.

Stellar manipulation: Whether trying to open a warp point and go through it at exactly the same time works or not depends on whether the warp opener has a lower ID than the moving ship. Also, destroying and recreating a planet in one turn with two different ships requires that the create order be executed either on a later day or on the same day by a ship with a higher ID.

Now for a way to make all this information actually useful: Ships are sorted in the fleet transfer screen by ID number, lowest ID at the top. This sort order is in effect both in the list of ships not in fleets and within each fleet. The order of the fleets is by fleet ID, which is used for nothing else that I can tell, except the order fleets are displayed in the ships screen (F6). The order ships are gone through by the "Next ship" operation, typically accessed by the space bar hotkey, is also by ship ID. Unfortunately, this order is cyclical and your current position in it appears to be stored in the savegame, even through turn execution. Of course, you could try building an escort on turn 1 specifically to keep it around forever as your known lowest-ID ship, but this isn't guaranteed to work perfectly unless you're player 1 - anything players before you build on turn one will have a lower ID, which could possibly be freed later and taken up by another one of your ships.

Another kind of stellar manipulation where ship ID can matter: star destruction/nebula creation/black hole creation. A ship moving on the same day as the scheduled mass destruction order has two possible options if it has a lower ID than the stellar manipulation ship. First, if it is on a warp point, it can warp to safety an instant before the superweapon goes off. Second, if it is one sector away from the stellar manipulation ship, it can move there and prevent the ship from doing anything, provided that you do not have a non-aggression or higher treaty with the owner of the stellar manipulation ship. If it has a higher ID than the stellar manip ship, it can't do anything but wait to die.

All orders that do not spend movement points happen just before the ship's next move action. This means that if a ship runs out of movement with a stellar manipulation or load/drop or similar order at the top of the queue, that order will not be executed until its first movement of the next turn.
