启用或禁用指定对象动画通道上的所有F曲线。F曲线是控制对象动画变化的曲线。使用该操作可以轻松地启用或禁用对象上的所有动画曲线,从而控制动画效果。
如果成功启用或禁用了F曲线,则返回 {'FINISHED'}。如果未正确指定data_path,则返回{'CANCELLED'}。
启用场景中所有选定对象的动画曲线:
import bpy
for obj in bpy.context.selected_objects:
bpy.ops.anim.channels_fcurves_enable(data_path="", action=None, layer=-1)
禁用所有相机位置Z轴上的动画曲线:
import bpy
camera = bpy.data.objects.get("Camera")
if camera:
bpy.ops.anim.channels_fcurves_enable(data_path="location", action=camera.animation_data.action, layer=-1)
f_curves = [fc for fc in camera.animation_data.action.fcurves if fc.data_path.endswith(".location") and fc.array_index == 2]
for f_curve in f_curves:
f_curve.enabled = False
