Class 9 Computer Science Layers and Frames Notes

To Delete a Keyframe/ Blank Keyframe:

• Put the red marker on any of the created frame number, go to the Insert menu on the Menu bar and select delete frame.

OR

• Right Click the mouse button on any create frame number and select the option Delete frame.

Concept of a Symbol

Flash provides the facility to store the objects (i.e. images and text) in a place called

Library. Everytime a symbol is selected from the library to be used in the movie, its copy is used and this copy of the symbol is called as the Instance.

MOTION, SHAPE TWEENING

Flash provides you the facility to show the transition of the image from one keyframe to another keyframe. This transition is called as Tweening.

Through tweening, the user can not only see the transition from one image to another in terms of its shape but also in terms of its motion. For example, through tweening you can show a ball bouncing or moving vertically or horizontally or showing the change in the color of the text slowly, etc.

Flash has two types of tweening:

1. Motion Tweening

2. Shape Tweening

Motion Tweening: It is used to tween the text/image in terms of its: Position (i.e. to show the object moving from one place to another), Scale (i.e. to show the change in the size of the object),

Rotation (i.e. to show the change in the angle of the object),

Color (i.e. to show the change in the color of the text/image in terms of making the object light/bright, etc.)

Motion Tween works only on symbols and will not work oh layers, which contain more than one symbol. Shape modification is not allowed in motion tweening.

Shape Tweening: Shape Tweening is used when the change in the shape of the object is required to be shown. For example, shape tweening can be used to show the conversion of a circle to a semicircle. Shape Tweening doesn't work on symbols.
