Weaving Motion Practice worksheet I

This worksheet explores the use of the motion path technique in flash animation. The motion path technique is very effective tool for describing complex motion of an object with out the use of actionscript (programming). With the path described on one layer and the object to be set in motion on the other, animators can cleanly separate content and behavior making complex animations from a collection simple paths.

Instructions

Step I	Name the first layer "posts". In this layer draw a set of balls distributed on the canvas that will act as obstacle posts.


Step II	Create a new layer and name it "ball". In the first frame draw a ball (using the circle tool and a radial gradient fill) and convert it to a graphic symbol named "ball_graphic". Then in frame 60 Right click and select "Insert Frame".


Step III	Right click on the "ball" layer and select "Add Motion Guide".

Step IV	In first frame of this motion guide draw a weaving line around your posts with the Pen tool to describe the path of the ball. (see how to use the pen tool)


Step V	In the "ball" layer, position your ball at the left end of motion guide path (with the graphic symbol centered on the line) then create a new key frame in frame 60. In keyframe 10 move the "ball_graphic" to right end of the motion guide path.
