This video will introduce you to another way to create Library Symbols which can be independently animated.
Create a new file called intro2-3.fla and create a scene with at least one character that needs a motion tween to move around. Think about what additional animation can make the character(s) come alive and create little Library Symbols for these eg blinking eyes, a talking mouth, hair moving...
When you have finished creating the full animation, save it and upload it to your Google Drive folder.
