I'm creating a simple add-on that allows you to give each frame a custom description and keywords, which I hope to write to a frame_name.txt file when the frame is saved.

I've got the basic option set-up working, but I can't seem to figure out how to get the option to reflect the current frame. Ideally, each frame should have a separate value to be input.


Frame 1:

  • Title: This is frame one.
  • Description: This is some guy doing something.
  • Keywords: Running, Race, etc

Frame 2:

  • Title: This is frame two.
  • Description: This is some guy doing something else.
  • Keywords: Jumping, Leaping, etc

I attempted to add custom names to each field using

current_frame = bpy.context.scene.frame_current

But that does not work since the values are only registered once. Perhaps I'm going about it all wrong? Its a simple frame-based information system.

What am I doing wrong to get this input-system frame-based and per object?

import bpy  
from bpy.types import Operator  
from bpy.props import FloatVectorProperty, FloatProperty, StringProperty   

current_frame = bpy.context.scene.frame_current


class PaperDoll(bpy.types.Operator):
    """Sequential Paperdoll Character Class"""

    bl_idname  = "object.paperdoll_operator"
    bl_label   = "Paperdoll Sequence"
    bl_options = {'REGISTER','UNDO','PRESET'}  

    root_title = StringProperty(
        name    = "Title",
        default = "Enter a Title"

    root_description = StringProperty(
        name    = "Description",
        default = "Enter a Description"

    root_keywords = StringProperty(
        name    = "Keywords",
        default = "Enter Keywords"

    def execute(self, context, event):  
        return {'FINISHED'}    

    def execute(self, context):  
        return {'FINISHED'}  

def add_object_button(self, context):  

def register():  

if __name__ == "__main__":  

A StringProperty gives you a single value for the scene, to get a new value for each frame you will need a list or collection to hold all the values for each frame.

Blender does offer a CollectionProperty which should suit your needs. You want to have a value for your string then an index or key that will be the frame that value is good for.
