Removing an FCurve

Question

I'm trying to delete an F-Curve. I'm aware that an F-Curve can be deleted when iterating through bpy.data.actions and using the ActionFCurves.remove method. In a case such as this, however, I'm not sure how to get to the F-Curve's ActionFCurves.

fcurves = bpy.context.visible_fcurves[:]
for fcurve in fcurves:
    if fcurve.mute:
        #deletion code goes here

Can anyone please advise on how to delete an F-Curve without having to loop through the bpy.data.actions? Thank you!

Answer 1

I think that you can get the action from the fcurve with the id_data attribute (since actions are an ID type):

for fcurve in bpy.context.visible_fcurves :
    if fcurve.mute:
        action = fcurve.id_data
        action.fcurves.remove(fcurve)

i changed a bit the beginnig of your code, you can also go for a one liner :

for fcurve in [fcurve for fcurve in bpy.context.fcurves if fcurve.mute] :
    action = fcurve.id_data
    action.fcurves.remove(fcurve)
