Collider Goal in Python: List[Object] type?

Hi everyone,

I am trying to use the K2 Collider Goal in Python, but I am having hard times understanding what does a 'List[Object]' is.

This is the error I am getting when feeding in a list of Lines:

"Runtime error (ArgumentTypeException): expected List[object], got list".

I tried to check in the C# example goal in Daniel Piker GitHub (https://github.com/Dan-Piker/K2Goals/blob/master/Collisions.cs) but I am pretty new in scripting and I could not figure out which is the problem.

Any help would be much appreciated,

Thanks.

Luca

It's referring to the .NET generic list type. To instantiate one using IronPython you can do like so:

# Import the type
from System.Collections.Generic import List

# Instantiate a list
myDotNetList = List[object]()

Edit: Object might be capitalized, I forget. Also, If you're making a list which contains a specific type (like say, Kangaroo2 goals) you might want to declare this instead of object (for instance: ks.IGoal with the KangarooSolver.dll imported under the alias ks).
