| Summary | 0020871: Ships teleport to a far away location when going through a wormhole | ||||
| Description | Some times when you order ships to go through a wormhole they teleport to a far away location from the wormhole after having gone through it, Steps to reproduce: -Start a new game with Raptors (I think it works better with fast ships) -Build a full cap (60) of Mark I Raptors on planet A -On planet A move the Raptors far away from planet B's wormhole -Order them to go through planet B's wormhole (Screenshot A) and DO NOT look at planet B yet because if you're viewing planet B it wont happen -Pause the game when about half of the Raptors seem to have gone through the wormhole (Screenshot B) -Look at planet B and see how some of the Raptors have teleported to a far away location from the A-->B wormhole (Screenshot C) Attached a save file and 3 screenshots. Load the save file and simply unpause the game and the Raptors will fly trough the wormhole. You can try viewing and not viewing the planet B and see how it affects this bug. | ||||

Thanks. This is related to a number of other cases as well. |

I think this is a race with the wormhole traversal and decollision code. In DoEntityStepLogic_Ship we check if the ship is going to go through a wormhole, and if it is then we call this.Planet.ShipsReadyForWormholeTraversalAtEndOfThisFrame.Add( this ); Then we call this.Inner_CheckForPlannedMove(); this function checks the outcome of the decollisiion logic, then updates the ship's location appropriately. I think the location update in Inner_CheckForPlannedMove() can under some circumstances happen after the wormhole traversal code run from EntitySimLogicImplementation.cs (which handles the ShipsReadyForWormholeTraversalAtEndOfThisFrame list), causing ships to first change planets, but then wind up at the location the decollision logic intends for them. A tentative fix is checked in, where we simply omit handling updates from the decollision thread for the first second after a ship changes planets. It's a bit hacky, but it seems to work. |

After testing with this case, as well as 3,000 ludicrously fast ships in several ways of entering wormholes, this issue appears to be fixed at last. |
