Hey,

I currently worked on a script which edits a map so I can delete specific models which are in the zone.

However

my Dict looks like this:

Syntax: Select all

removeDict = {'mg_course_dev_server': {'deletelist': [], 'deleteCoords': [(Vector(-385.1864318847656, 3057.462646484375, 22.29857063293457), Vector(-144.25393676757812, 3600.712646484375, -31.96875), Vector(-468.97247314453125, 2856.05029296875, 43.889564514160156), Vector(0.0, -95.67604064941406, 0.0))]}}

When I want to save it via this script (which worked on 2.5)

Syntax: Select all

def saveDict():
    fileStream = open(mapsPath, 'wb')
    pickle.dump(removeDict, fileStream)
    fileStream.close()

Im getting

Code: Select all

RuntimeError: Pickling of '_mathlib.Vector' instances is not enabled (http://www.boost.org/libs/python/doc/v2/pickle.html)

You can work around that issue by converting the Vector instances to a tuple when you want to save it. Then, when you read it, you simply create Vector instances from the tuples.

If you need some more help you could look at my SpawnPoints cookbook example. It uses JSON and list(), however the principle is the same: viewtopic.php?f=31&t=751 [needs to be updated, haven't looked into it for ages...]

How would that look like

I believe like this way

Vector -> tuple

Syntax: Select all

tuple(my_vector)

tuple -> Vector

Syntax: Select all

Vector(*my_tuple)

Works, thank you

I have added pickle support for the mathlib classes, so pickling Vector instances will work with version 345:

Ayuto, could you also add a "normalized" - method to mathlibs Vector module? right now, im always changing it locally, but always have to update it myself. would help if its added to sp too. the math is just : copy the vector and divide it by the native Vector.normalize(). thanks
