# Career Limits¶

The theme of KSP’s “career mode” is that some features of your space program don’t work until after you’ve made some upgrades. kOS now supports enforcing these checks, as described below.

## The rules being enforced¶

These are rules inherited from the stock KSP game that kOS is simply adhering to:

• If your tracking center is not upgraded far enough, then you cannot see future orbit patches.
• If your mission control center AND tracking center are not upgraded enough, then you cannot add manuever nodes.

The following are rules invented by kOS that are thematically very similar to stock KSP, intended to be as close to the meaning of the stock game’s rules as possible:

• In order to be allowed to execute the PartModule :DOACTION method, either your VAB or your SPH must be upgraded to the point where it will allow access to custom action groups. This is because otherwise the :DOACTION method would be a backdoor “cheat” past the restricted access to the action group feaures of various PartModules that the game is meant to have.
• In order to be allowed to add a nametag to parts inside the editor so they get saved to the craft file, you must have upgraded your current editor building (VAB or SPH, depending) to the point where it allows at least stock action groups. This is because name tags are a sort of semi-advanced feature.

You can see some of these settings by reading the values of the Career() global object, for example:

print Career():PATCHLIMIT.
print Career():CANDOACTIONS.


## Structure¶

structure Career
Members
Suffix Type Get Set
CANTRACKOBJECTS Boolean yes no
PATCHLIMIT scalar yes no
CANMAKENODES Boolean yes no
CANDOACTIONS Boolean yes no
Career:CANTRACKOBJECTS
Type: Boolean Get

If your tracking center allows the tracking of unnamed objects (asteroids, mainly) then this will return true.

Career:PATCHLIMIT
Type: scalar Get

If your tracking center allows some patched conics predictions, then this number will be greater than zero. The number represents how many patches beyond the current one that you are allowed to see. It influences attempts to call SHIP:PATCHES and SHIP:OBT:NEXTPATCH.

Career:CANMAKENODES
Type: Boolean Get

If your tracking center and mission control buildings are both upgraded enough, then the game allows you to make manuever nodes (which the game calls “flight planning”). This will return true if you can make maneuver nodes.

Career:CANDOACTIONS
Type: Boolean Get

If your VAB or SPH are upgraded enough to allow custom action groups, then you will also be allowed to execute the :DOACTION method of PartModules. Otherwise you can’t. This will return a boolean letting you know if the condition has been met.
