Position and Rotation Tweening Practice I

Flash can not only create single tweens that calculate the intermediate states of an animation it can also perform multiple simultaneous tweens. This is because the animations are based on vector information which can be added together. The effect is that relatively complex motion and simulations can be achieved by simply adding multiple tween effects to an object.


Rotation	+	Displacement	=	Roll

In this exercise we will create a rotation tween on a basket ball then move its final position. The resulting effect will be the ball rolling from one location to the next.

Exercise I Position and Rotation Tween.

Download this .fla

Step I	Download this image. Then open a new flash file and import the image onto the stage.


Step II	Rasterize the image.

Step III	Apply a simple rotation tween to the basketball (1 clock wise rotation).


Step IV	Move the position of the ball in the final keyframe. Then add a few frames to create a pause at the end of the animation.

Exercise II Position and Rotation Tween.

Using these images create your own "rolling" animations.

Note: In each case Flash automatically converts the drawn object or the image into graphic symbol in order to create/calculate the tween (images between the keyframes).
