(Python) (Blender) How can I take the number of every frame on which there are markers?

Question

有没有办法获取时间轴上有标记的每个帧编号，并将其设置为所选对象上f曲线的噪波修改器 r的起点？

Answer 1

The marker data can be found in scene.timeline_markers

The fcurve data is in object.animation_data.action.fcurves

If you wanted to add a noise modifier that lasts 10 frames starting at each marker you could use -

import bpy

# data_path='location' with an index=1 is the y location curve
fc = bpy.context.object.animation_data.action.fcurves.find('location', index=1)

for m in bpy.context.scene.timeline_markers:
    nmod = fc.modifiers.new(type='NOISE')
    nmod.strength = 1.5
    nmod.use_restricted_range = True
    nmod.frame_start = m.frame
    nmod.frame_end = m.frame + 10

Note that the fcurves.find() used here is only available from blender 2.76+, for earlier versions you will need to loop through the fcurves and test the data_path to find the one you want.
