Another LNSU challenge
I just had an idea of how to force the player to take a specific path through space (no, its not specially-shaped deadly spobs, although that would work)
Lets say that the mission is for the player to investigate howevermany hostile stations by flying by them and "taking pictures".
Here's how it works:
The mission triggers a series of invisible missions to make this accomplishable.
There is a ship which is an escape ship that carries itself as an escape ship (recursive escape ship). This ship is given to the player.
The stations all have a gun with perfect accuracy/speed, and a short range. Damage values can be adjusted. All are hostile to the player. The gun will kill the player in two shots. Reload time is however long you want the player to hang each station for. The guns only have two pieces of ammo so that each station can only destroy the player once.
The invisible missions all fail on player destruction/ejection/whatever.
The player flies by the first station. The station kills him, forcing him to eject into a new ship, and forcing the invisible mission to fail. This sets a bit (say, b1) and triggers another invisible mission.
The player flies by the second station, The station kills him, forcing ejection, making the current invisible mission fail, thus setting b2 and starting another mission.
And so on and so forth for howevermany stations.
If the player doesn't visit all the stations, not all the bits will be there, and the visible mission won't complete.
Can the player change ships mid-flight without ejecting (mission-triggered)? If so, then the station will only disable the player, the mission will fail on disable, and make the player change into a new ship. This way the player can have a limited number of ships, which is useful if enemy ships are in the system (the player might actually fail the mission).
Hey, maybe by using the "grant pay on failure" flag, the mission can make the player's government status change, and therefore force the player to visit the stations in a specific order, if each station has its own govt.
