Flash Templates Tutorials - Animated symbol - Converting animations from the scene into the movie clips
Converting animations from the scene into the movie clips - If you have created animation on the scene, and want to use it elsewhere in your clip, or if you want to manage this animation as an instance, you can mark it and make a movie clip from it. For inter-conversion right click for Windows or Control-click for Macintosh ... and then select 'Copy frames from the context menu',
mark each frame including all layers of your animation. Make sure that nothing is marked in your scene. And select Insert > Create Symbol from the menu. Name the symbol as you wish, select 'Movie Clip' in the properties and then click OK. Flash will open a new symbol at once and even will enable symbols editing mode.
Mark the first frame at the timeline and select Edit / Paste Frames. Select Edit / Edit Movie to return to the regular mode, remove animation from the main timeline: mark all frame and layers, and select Insert / Delete Frame
Note: while working in Flash, it is useful to bear in mind the possibility of canceling some of your previous actions: use Edit / Undo or Ctrl + Z for the step-by-step canceling, to restore the cancelled actions, use Edit / Redo or Ctrl + Y.
