Flash has two identical keyframes, and inside the frame is the shape, which changes when the shape t

You're right, the first and last frames must be keyframes to create a tween or shape tween, and tweens that animate on the timeline will be straight lines, while tweens that can't be animated are dotted lines: "actions" are used to move and scale and distort objects, while "shapes" are used to make changes between objects. The former only moves a single object, while the latter can do the mutual transformation of two objects.

This is related to the objects that are dealt with by Actions, which deal with Component objects, and Shapes, which deal with foundations or broken objects.

It is important to note that when deforming an object (i.e. "shape"), you must have a separate layer for the deformation of the object, otherwise the animation will not work properly (i.e. there is only the object to be deformed in this layer, and there are no other components, because the deformation is usually done on the front and back objects).

The difference between a shape tween and a traditional tween is that the shape tween creates an automatic change in shape and color, and the traditional tween creates an automatic change in position.

Auto-changes are automatically generated by the software, so the premise is that your two keyframes have a different shape or color or position. Otherwise, of course, nothing will change.

1. First of all, open Flash Professional 8 and set the desired color in the color panel, such as blue.

2. Then click on the Rectangle tool to draw a square.

3. Right-click at a certain point on the timeline and click to insert a blank keyframe.

4. When a blank keyframe appears on the timeline, select the Ellipse tool. Draw a circle and break up both the square and the circle.

5. Right-click anywhere between the 1st frame and the last 1st frame, and select Create Tween.

6. The creation of the tween animation is successful, and the realistic line arrow is displayed in the middle, and this is done.

There is no difference between the first frame insertion and the middle insertion tween;

Select "Conventional Tween" when both keyframes are the same element (movie clip, shape, or button), and "Tween Shape" when both keyframes are vector graphics.

Flash also has a way to animate the tween is "tween", which is different from the previous two creation methods, which only needs a keyframe, adds a normal frame to the end, and then changes the state of the object on any frame (such as moving and scaling, etc.) after creating the "tween", note that the object must be a symbol.

There are four types of frames in Flash. They are as follows:

1) Keyframe: A "solid dot" on the timeline means that this frame is a keyframe, and the frame that generally needs to be changed is inserted into a keyframe.

2) Normal frame: In order to continue the content of a certain keyframe, you need to insert an ordinary frame, which has no obvious mark, but a darker color.

3) Blank keyframes: keyframes without content, the timeline is a "hollow dot", indicating that this frame is a blank keyframe.

4) Transition frame: The frame that is purple or green in the middle of the motion or shape tween is called the transition frame, which is automatically generated when the motion or shape tween is made.

The answer should be that there are three types of keyframes: keyframes, extended frames, and blank keyframes.

Option A, 3 types.

1. Normal frames, also known as static frames, show the content of the last keyframe on the same layer. On the Timeline, keyframes must always be in front of normal frames. The contents of the leading keyframe are displayed in each subsequent normal frame until another keyframe is reached.

2. Keyframes, keyframes are special frames used to define changes in animation, including the movement and characteristics of objects (such as size and color), adding or removing objects in the scene, and adding frame actions. Keyframes must be used anytime the user wants the animation to change, or if they want an action to occur.

3. Blank keyframes are almost the same as keyframes, except that it is inserted without an object, and it is blank!!

There are 2 types, normal frames (static frames) and keyframes.

1.Keyframe 2Blank frame 3General frames.

Normal frames, normal keyframes, blank keyframes.

There are three types of flash frames: normal keyframes, normal keyframes, and blank keyframes. Keyframes are divided into blank keyframes and normal keyframes. Keyframe is any animation to show motion or change, at least two different key states should be given before and after, and the change and connection of the intermediate state can be done automatically by the computer, in flash, the frame that represents the key state is called a keyframe.

A blank keyframe is a key state of the frame, and when the picture has not been added, it is called a blank keyframe.

Keyframe, that is, this frame is to connect two different pieces of content, and there will be new changes or transitions in the ** content behind this frame; On the time pants crack axis, this frame has a small black dot to mark the pure code mark;

Blank keyframes, which have the same effect as keyframes, but there is no content in this frame, and there is no small black dot in this frame on the timeline; Once this frame is filled with content, it becomes a keyframe;

The normal frame is used to measure the time or transition time, and the content of the ordinary frame cannot be set manually, it is automatically filled by the front and rear keyframes and the transition type in the process, and the manual insertion or deletion of the ordinary frame will change the transition time between the two keyframes before and after.
