SOLVED utils.ViewportSelect() Problem

Hi! guys! Here's the problem with utils.ViewportSelect()

This is my code:

ViewportSelect = c4d.utils.ViewportSelect()

frame = bd.GetFrame()
left = frame["cl"]
right = frame["cr"]
top = frame["ct"]
bottom = frame["cb"]
width = right - left + 1
height = bottom - top +1

pick_obj = ViewportSelect.PickObject(bd, doc, mx, my, 0, c4d.VIEWPORT_PICK_FLAGS_0)
print pick_obj

ViewportSelect.Init(width, height, bd, pick_obj, c4d.Mpolyedgepoint, True, c4d.VIEWPORTSELECTFLAGS_IGNORE_HIDDEN_SEL)
for obj in pick_obj:
        print obj
        nearest_poly = ViewportSelect.GetNearestPolygon(obj, mx, my, 0, False)

Cinema 4D giving feedback: RuntimeError: Object is not initialized yet.
How can i fix it?

Hi,

you cannot use the ViewportSelect before you have initialised it. So you can only invoke PickObject() after you have invoked Init().

ViewportSelect.Init(width, height, bd, pick_obj, c4d.Mpolyedgepoint, True, c4d.VIEWPORTSELECTFLAGS_IGNORE_HIDDEN_SEL)

pick_obj = ViewportSelect.PickObject(bd, doc, mx, my, 0, c4d.VIEWPORT_PICK_FLAGS_0)

Like this? But C4D giving feedback: UnboundLocalError: local variable 'pick_obj' referenced before assignment.

Hi,

unless you have defined pick_obj somewhere else you cannot pass it to your Init() before you actually define it in the next line.
