Creating An Animation (part 2) Alice

Recall from last lecture We began the animation creation process We introduced the concept of storyboard We will continue using the example presented last lecture

Step 2: Implementation Implementing an animation requires Setting Up the Initial Scene Writing the Program (Script)

Create Initial Scene

Techniques and Tools Mouse used to set up the initial scene approximately position objects in the scene Camera Navigation is used to set the camera point of view One-Shot Instructions are used to resize objects more precisely position objects in the scene Scene. Editor's Layout Manager is used to obtain specific alignments position one object relative to another object

Writing A Program "Writing" a program (script) a list of instructions to have the objects perform certain actions in the animation

Writing the Program Our planned storyboard (to-do list) is: Snowman turns to face snowwoman. Snowman “makes eyes” and calls out to snowwoman. Snowwoman turns around. The idea now is to put the plan into action How do we translate from the plan to actual program instructions?

Translating the Plan into Actions Some steps in the storyboard can be written as a single instruction The snowman turns to face the snowwoman The snowwoman turns her head Other steps are composite actions that require more than one instruction The snowman tries to catch the snowwoman’s attention is two actions Snowman says “ahem” Snowman raises and lowers his eyes

Actions Sequential Some actions occur one after the other first step (snowman turns to face snowwoman) second step (snowman tries to get snowwoman’s attention) third step (snowwoman turns around) Simultaneous Other actions occur at the same time Snowman makes eyes at the snowwoman while simultaneously calling out to her
