PROPERTIES OF AN OBJECT YOU CAN ANIMATE WITH A MOTION TWEEN
- An object’s location
- An object’s scale
- An object’s rotation
- (For symbols only) An object’s tint/transparency
RULES FOR A MOTION TWEEN
- The animated “object” must be on it’s own layer
- It must be either a grouped object or a symbol
- It must be the ONLY thing on it’s layer
- There must be two keyframes for the motion tween to be between
- The “objects” in each keyframe must be the same object.

MORE ABOUT KEYFRAMES
- Whenever you add a keyframe where there is no motion tween, it is a duplicate of the previous keyframe.
- A Keyframe means either:
- Something is different on this frame
- OR -
- Something will begin to be different on this frame
- When you modify or add anything to the stage, you are always modifying a keyframe.
- If you are on a frame that has no keyframe and no motion tween (like frame 10 in the illustration below), any edits that you make are happening to the most previous keyframe.

- If you are on a frame that is in the midst of a motion tween all you will be allowed to do is change the object’s location. Once you do this, a keyframe will automatically be created on that frame, allowing you to make other edits.
