Week 0 – Flash Animation Course Day 3

Day 3 Morning – MovieClips and Tweens
The first part of the morning was spent showing the class the two major tweens used in flash before CS4: Motion and shape. Tweens are a kind of shortcut for animation in flash. You put the object you want to animate in a position at the first and last frames you want to animate and flash does the rest of the work.
The students learned that a shape tween can only be applied to the area between two keyframes on a layer without symbols in them. Similarly, they learned that motion tweens can only occur between two keyframes on a layer that have only one instance of the same symbol in that frame.
The second part of the morning introduced the students to MovieClips. MovieClips are a type of symbol that instead of being a static graphic can be a looping animation. I showed the students how to put their lip-synched animations into a MovieClip and then animate that MovieClip using a tween.
Day 3 afternoon – Walk Cycles, Motion Guides and exporting to Quick Time

After instroducing looped animation using MovieClips I continued to show the class what a walk cycle was. A walk cycle is a looped animation showing a character walking. Making a walk cycle and then animation the movieclip with a motion tween is a great shortcut to get characters moving quickly and effectively.
We started off with a very simple walk cycle for a stick man – each arm and leg was a symbol, then each one was put on a seperate layer and animated using tweens in order to give the feel of a walk (even if it was very stiff and stilted). After they each had a simple walk cycle I got the students to break the arm and leg symbols up into forearm, arm, thigh and shin, so that the character would have working knees and elbows. I then got them to analyze somebody walking in order to find the best way to make the walk look realistic.
A lot of students at this point took the opportunity to use their lip-synched face animation as the head for their stick man. I commend their creativity.
Once everyone had a walk cycle completed, I showed the students motion guides. Motion guides are a line that can be paired with a layer in order to manipulate the path a tween follows – so that you can create a more diverse movement than just a straight line.
Finally, I taught the students the procedure for exporting an animation to the Quick Time .mov file format for use in video
The final part of the afternoon session was setting a quick one-day project for the students to consolidate the skills that they had picked up. Details to be posted in the day four post.
Day four will be posted up shortly.

CYEC sent a small team of volunteers to Guyana in Summer 2009 to equip young people with online skills.
