help with log error message

[DGill]

Ive used the line:

if(missionVariables.access == System.systemNameForID(system.ID))

but get a log error message (Oolite 1.75.1) of:

Error: System.systemNameForID: Invalid arguments (-1) -- expected system ID

any help to sort it out would be appreciated

That should only happen in interstellar space (i.e., after a misjump). You can’t look up a system that doesn’t exist.

In any case, what’s wrong with system.name ?

there was a misjump so that must be it - thanks Ahruman

I have the if statement following the call:

this.shipExitedWitchspace = function()

is there a test I can use in the if statement to exclude misjumps?

"what’s wrong with system.name ?" - ??? not sure, I'll have a look at at the wiki pages again to see if I've missed something

Yep, system.name does work fine in interstellar space, and it's also faster than System.systemNameForID(system.ID))!

Still, -1 is a valid - albeit special - system id meaning 'generic interstellar space'. Maybe amend systemNameForID to return the 'interstellar space' string for -1?
