MUIDrawManager.lineList python returns an error when it's passed an MPointArray

[calibrix]

I'm trying to create some custom UI elements using the MPxLocatorNode class. This is my first time using viewport 2.0. I'm following the basic setup from the pyFootPrintNode.py file. When I get to MPxDrawOverride.addUIDrawables function. I'm finding that the MUIDrawManager.lineList function does not work. My code looks something like so: drawManager.lineList(om.MPointArray, False) The MPointArray is a variable of course. In maya, the function draws the lines, but throws an exception: // Error: SystemError: file C:/Users/Chris/Documents/maya/homeEnv/plugins/FxLocator.py line 149: error return without exception set //

I don't see what I'm doing wrong. Perhaps someone with more viewport 2.0 experience can help out.

Hi,

It should be a bug. I've logged it as a defect in our system. Our engineers will look at it.

Yours,

As a work-a-round I found I can use MUIDrawManager.line and loop through my MPointArray object.

for i in range(0, MPointArray().length(), 2):

    MUIDRawManager.line(MPointArray[i], MPointArray[i+1])

Same is true for lineStrip() by the way
