How to set effector translation using python?

[1284933037]

I want to change the world position of effector.first,I get the effector

TargetCharacter = lApp.CurrentCharacter
rigEffector_L = TargetCharacter.GetEffectorModel(FBEffectorId.kFBLeftKneeEffectorId)

then, I sucess get the world position of the effector

world_pos = FBVector3d()   
rigEffector_L.GetVector(world_pos , FBModelTransformationType.kModelTransformation, True)
print(world_pos )

 the finally,i try to set new world position of the effector,but failed

world_pos2=FBVector3d(world_pos[0],world_pos[1],0)
print(world_pos2)
rigEffector_L.SetVector(world_pos2, FBModelTransformationType.kModelTransformation, True)

,nothing happened .

then I try to set the new value in animation curve，but something happened I cant understand,

the curve key value had change，but the properties didnt change，I  was confusion.

have you used

FBSystem().Scene.Evaluate()

after setting Vector? This function is important after functions like SetVector or SetMatrix, because it updates whole scene after setting transformations programatically.

BTW. if you want to get position vector then it would be better to use this attribute 

FBModelTransformationType.kModelTranslation instead of FBModelTransformationType.kModelTransformation.

kModelTranslation - means position

kModelTransformation - means whole obj transform (position, rotation and scale)
