'Parameter must be a Guid or string representing a Guid' Help

Hi, I am having some issues with python scripting in grasshopper. For all my (limited) experience and research this should return a 'True' boolean value.

Unfortunately I keep getting the error:

'Runtime error (TypeErrorException): Parameter must be a Guid or string representing a Guid'

My print function returns:

[<System.Guid object at 0x000000000000003A [57e6def5-658b-4347-b7ad-a125509c7c97]>]

ResetObjs = rs.GetObjects("Game Over -- Click Reset", 8, False, True, None, False)
print ResetObjs

ReStart = rs.IsObjectSelected(ResetObjs)

I feel there is an obvious solution, any help will be greatly appreciated.

Also note I am doing this in the python editor in grasshopper and bobbing in and out of rhino and grasshopper using 'scriptcontext' library.

GetObjects returns an array of objects. The clue is in the name -s, plural. IsObjectSelected expects to operate only on a single object.

You must either use GetObject(...) or loop over your ResetObjs selection.

Excellent, thank you for pointing me in the right direction. It has been a while since I have played with this.

I am now getting a value of '2' when I print the outcome of rs.IsObjectSelected. Does the mean the command hasn't worked? I was expecting a 0 or 1 at least.

I think there's more than one way for an object to be selected. Something about being persistently selected or only for the duration of a picker, and then there's sub-object-selection. I guess you'll have to look at the documentation to see what each integer represents.
