Working with Flash
Flash is computer animation software that is used to make movies, websites, games etc. Some of the important terms while working on Flash are Frames, Keyframes, Playhead and Layer. Frames are little rectangular cells on the Timeline. Keyframes are the frames with specific contents that are created to insert into the movie inexistent content. Playhead indicates the current frame that is displayed on the stage. Layers are used to organize the artwork and animation in a document.
An object can be selected, transformed, rotated, flipped, copied and moved. There are two methods to create an animation: Frame-By-Frame Animation and Tweened animation. In frame-by-frame, images are created in every frame. In tweened animation, both starting and ending keyframes are created and the animation is created between these frames. Two types of tweened animations can be created in Flash: Tint tween and Shape tween.
Tweening is a process of producing intermediate frames "in between" the key frames of an animation to give an impression of a continuous movement. In motion tween, position of the symbol is specified in the beginning and ending frames and Flash fills in the in-between frames. Shape tweening only works with vector images and with objects that are not symbols and ungrouped. When the shape of one object is changed into a new one, it is known as morphing. Motion Guide Tween is used to move an object on a path. Masking is used to selectively block the areas of a layer.
