Week 12: November 16 to November 22
BLOG topic Week TWELVE: Animation is a very broad label for the activities you are getting into this week in Flash. Animation comes by duplicating and then moving individual elements on the stage, sometimes with Frame-by-Frame animation and sometimes with Motion or Shape Tween animation. Please discuss the differences between these and why you'd pick one type over the other. What part does Symbols play with Animation?

Motion tween lets you move an object (graphic, button, movie clip, text) from one point to another and also change properties of the object. Classic tween lets you have more than one instance of an object during a tween span (p.4-20). So classic tween would be good to use if you want to have the object start with one speed or other characteristic, then stop, then begin again and behave in a completely different fashion.
Frame-by-frame animation offers even more control, with each frame functioning as a separate picture of the object: just like a movie.
Shape tweens morph the shape of an object from one form to another.
I'd use (have used) shape tweening to try to surprise the viewer as to what's happening on screen; that one object can become another.
I may be wrong here, but I think that symbols must be used for each type of animation.

I'm not going to duplicate what Ruth said, as she explained this rather well. It seems to me that one of the "tweens" I seen use most is motion Tween. It generally works well for most animation needs. Frame by frame would give you even more control, although it's more time intensive.
I second Hollingswoth in his seconding of Ruth, but not entirely.
I don't think one technique overall gives greatest control and or better time management. In the lab i have seen Mark take tweening to a greater level, resulting in much more time usage for the higher quality of his finished work. I have worked with the frame by frame animation and love the diversity, in that each frame can have it own absolute settings. Time speeds by in animating using frame by frame too, but it can be done at a rabbits pace as well; control takes practice;practice makes perfect. Lastly animating by morphing an object can be just as rewarding as the other ways of animating.
More effort, more control, more time equals unparalleled user impact. Im putting time into all three animations because all three by application have unique uses.
I apply and un-apply the symbol so i may give attributes to the animation, also in different frames this is nice that the symbol is already in my library so I copy and paste it.
I'm really having a hard time with the tweening - I think that the built in tween tools and motion paths are really helpful in Flash. Tweening is where you set up the beginning frame of an object to animate, then you insert a keyframe into the frame where the animation will end. Then you insert a preformatted motion tween or you can do step-by-step animation. I think that step-by-step would be helpful if you are doing alot of changes to the symbol along the animation path(i.e. alpha, color, shape, etc.). The symbol tools are cool - I'm just beginning to understand them a little better. What I found out the hard way, was how to create your symbol and then if you want to copy it and change it, you break it apart and then it becomes an "instance" where you can customize it without changing the original symbol.
One other neat thing about symbols is that once you've created them, everytime you make a change to it, all the places you've used the symbol in your animation will change also.
You are all fairly correct on Tweening. Ruth, shape tweens do not have to be symbols to work, although CS4 has done a few things to this concept too. Just remember that when you are using tweens, Flash is doing all the 'in-between' work for you. This all happens in those F5 frames that are just for Flash to use. When you are using Frame-by-frame animation you are using those F6 and F7 frames that you control.
