The difference between flash cs4 tween animation and traditional tween animation lies in the difference between the boot layer and the traditional boot layer.

The difference between tween animation and traditional tween animation should only appear in flashcs4. If you use it in an earlier version of flash, you should be more accustomed to using traditional tweens.

The order of traditional tween animation is to determine the key frames at different time points on the time axis (each key frame must be the same MC), and then select the traditional tween between the key frames to form the animation. This animation is the simplest point-to-point translation, that is, an MC moves from one point to another at a constant speed. There is no speed change, no path deviation (arc), and all effects need to be adjusted by other subsequent methods (such as guiding lines and animation curves).

The new tween animation is that after MC is drawn on the stage, you don't need to type keyframes elsewhere in the timeline. Select tween animation directly on this layer, and you will find that this layer turns blue. After that, you only need to select the place where you need to add the key frame on the time axis, and then drag the MC on the stage directly to automatically form the tween animation. Moreover, the path of this tween can be displayed directly on the stage and can be adjusted by adjusting the handle.

Generally, when using the 3D function of cs4, this kind of tween animation will be used. Generally speaking, FLASH projects are more traditional. It is easier to control, and the traditional tween is smaller than the new tween animation and easier to load in the web page.
