HairGuides.SetPoint(id, p) has the same explanation as GetPoints()
"Gets a list of points for the guides."
This is of course wrong.
HairGuides.GetPoints() is also listed twice in the R13 sdk.
Concerning the rest of the SDK and Hair. There's not much there.
There isn't even an explanation on how to create hair objects and guides.
So here's an example I put together:
import c4d
def main() :
obj = c4d.BaseObject(c4d.Ocube) #Creates a Cube in memory only
doc.InsertObject(obj) #Adds it to the OM
ho = c4d.BaseObject(1017305) #Creates a hair object in memory only
ho[c4d.HAIRSTYLE_LINK]= obj #Puts the cube into the hair's link field
doc.InsertObject(ho) #Adds it to the OM
c4d.DrawViews(c4d.DRAWFLAGS_ONLY_ACTIVE_VIEW|c4d.DRAWFLAGS_NO_THREAD|c4d.DRAWFLAGS_NO_REDUCTION|c4d.DRAWFLAGS_STATICBREAK) #forces redraws
ho = doc.SearchObject("Hair") #Lost the focus upon creation so we need to get it again
guides = ho.GetGuides() #Assign the guides to a variable
gcount = guides.GetCount() #Gets the number of guides
print gcount
segcount = guides.GetSegmentCount() #Number of segments per guide (number of points is one more than this)
print segcount
gpcount = guides.GetGuidePointCount() #Gets the number of points per segment.
print gpcount
owner = guides.GetObject() #Gets the guides owner object
print owner.GetName()
pnts = guides.GetPoints() #Gets a list of the points on all of the guides.
print pnts
guides.SetPoint(17, p= c4d.Vector(0,500,0)) #Moves one of the hair points to this vector position
ho.SetGuides(guides,clone=False) #Error:The object doesn't own the guides!! Really?..Then who does?
c4d.EventAdd()
if __name__=='__main__':
main()
I'm not sure what's going on with the SetGuides() function.
In C++ the hair object owns the guides. And the python SDK also says the same thing.
Yet I get an error that the hair object doesn't own the guides in my code.:dizzy_face:
I'm not sure if that's a real bug. Or another one of those things that's documented clearly.
