Basic knowledge of flash

First of all, you need to understand what a framework is. All kinds of frames belong to the concept of frames. In fact, it can be understood as the process required for the passage of time. The animation will continue when arranged frame by frame, and then the difference between key frames and ordinary frames is that you arranged the picture of the moment of the process represented by this frame. If you want to put something on this frame as you want, turn it into a key frame, or when you want to put components on the scene, you can create a new key frame and put it on it. Similarly, when you want to choose an object on the stage, you will inevitably choose a key frame, because this is a static moment you arranged. Blank keyframes are like a concept between normal frames and keyframes. It is a key frame, but it has some characteristics of ordinary frames. It is usually used to delete the object you put on the stage in the last keyframe. This frame represents blank, and there is nothing on this frame. This is a blank moment and can also be used to add a timeline.

Now, when you want to create an animation, the animation must have a beginning and an end. According to the concept mentioned above, these two moments are arranged by you, so both of them will occupy a key frame. Two key frames, one is the beginning and the other is the end. Then create a tween between two key frames, and an excessive action will be automatically generated in the middle. Now you know when to insert a key frame. That is, when you want to create an animation according to your own meaning, you need to insert a key frame in the first and second pictures. If you want to slow down the animation, it means that the animation will run for a long time. If you look at the above, that frame is delayed, so insert a frame between two key frames, so the animation time will not be very long, a continuation of time.

As mentioned above, blank keyframes are mainly used to make the pre-existing content disappear and add code to it. Of course, if you don't continue the box, there will be no box behind, and it will be blank. It's just that animation is sometimes needed at the back of this layer, so the frame must be continued, so that the frame can be converted into the key frame at the back to put the picture you want.

The above is different from the dogmatic interpretation of various information books, but tries to use an interpretation that seeks understanding and image. When I first started learning, I also encountered your confusion that I didn't understand. I hope this article is helpful to you.

If you find it useful, don't forget to give me the best one.

2.flash basic knowledge short answer questions

1. You can set the scene size. Right-click in the workspace and select "Document Properties …" from the shortcut menu to pop up the following menu: In the "Document Properties" window, you can modify the film properties: 1, and the size: determine the stage size. The above picture is now 550 X 400 (width x height). 2. Stage background color: click the color block to modify the background color.

3. Frame rate: that is, the speed of animation playback. The picture on the left is now 12 frames per second (fps). 4. Proportional units: centimeters, pixels and inches can be selected. Second, rename the layer Click the layer you want to rename, and double-click the rename layer.

Third, delete the layer Click the layer to be deleted and click the trash can to delete the layer, as shown in the figure (trash can in the lower right corner): Fourth, click the layer to be moved with the black arrow tool for moving the layer, hold down the layer to be moved and drag the layer up or down with the left mouse button. V. Copying Layers There seems to be no function of copying layers in Flash, only copying frames and pasting frames: click the frame to be copied with the Shift key on the time axis, right-click to copy the frame, then insert the layer, click the first frame of the new layer, and right-click to paste the frame to copy.

6. Set the animation of the fade-in and fade-out effect (this problem is not clear in one or two sentences). Take the fading effect of a picture as an example: 1. Drag the picture from the library to the stage, set the size, and right-click the picture to convert it into an original (either a movie clip or a graphic original). 2. Insert key frames in the 20th, 80th and 100 frames of the time axis respectively. Do the same for the frame 100.

3. Right-click any frame from frame 1 to frame 20 to create tween animation, and right-click any frame from frame 80 to frame 100 to create tween animation. Seven, you can set the frame rate according to the requirements of the third answer in question one.

Eight. Motion and shape tweening animation Right-click any frame from frame 1 to frame 20 to create tweening animation, and right-click any frame from frame 80 to frame 100 to create tweening animation. Nine, you can choose to set animation on the mask layer or the mask layer according to the setting intention. X. You can modify the properties of the object: (After modifying the content of the component, all references to the component will change) XI. Specify the frame according to the time. 12. Import the picture into the specified layer 1. External materials such as sound, pictures and videos can be applied in flash, and these external materials can be introduced into the command of Flash (library or stage) through File >: Import ...

2. Import one picture, and import multiple pictures (consecutive pictures, select multiple pictures with ctrl or shift) 3. Import the picture into the specified layer: click the first frame of the specified layer to import the picture, and then click File > Import ... to introduce the command to the stage. I'm going out because of the time.

It's too late to say two in the middle. Please forgive me.

3.flash learning knowledge points

The following knowledge points cover the basic and intermediate knowledge points of FLASH, and the latter two points are particularly important in design, guidance and masking. (software ADOBE FLASH)

What is frame animation?

Frame-by-frame animation has become a frame-by-frame animation. Frame-by-frame animation is the basic form of animation and can be used when it is necessary to show the motion effect of objects in detail. Frame-by-frame animation has different content in each frame. As we all know, in Falsh, key frames will affect the volume of published works. The more key frames, the more works. Therefore, in practical use, frame animation and tween animation should be used reasonably according to the needs of the content of the work. What is tween animation?

The so-called tween animation is also called intermediate frame animation and gradient animation. As long as the start and end pictures are established, the middle part is automatically generated by the software, which saves the tedious process of making the middle animation. This is the charm of Flash, and tween animation is the most commonly used animation effect in Flash. What is shape tweening?

Shape tweening, also known as shape gradient, is suitable for graphics. Shape tweening can realize the effects of moving, scaling, rotating, filling gradient, accelerating, decelerating and deforming objects. The start and end objects of a tween shape must be graphics (shapes). The drawings drawn by the tools in the Flash software toolbox are graphics, which can be directly used for shape interpolation. What is an action movie?

Tween animation, also known as motion gradient, is suitable for components. Tween animation can achieve the effects of position movement, size change, color change, transparency change, light and shade change, tone change and so on. The start and end objects of tween must be components. What is the way to distinguish between graphics and components?

Select the black arrow tool and click an element in the scene. If elements are pitted, they are graphics, and those with blue borders are component or combination graphics. If you want to use a tweened shape when the element is not a graphic, you can use the "Break (Separate)" command. When an element is not a component, if you want to use tween animation, you can use the Combine or Convert to Component command. Method of using guide wire

The guide line is actually a trajectory built on the guide layer and given motion. First, note that the guide layer should be above the motion layer, and enable the Align Objects tool. Pay attention to the alignment (adsorption) mask layer of the registration point at the beginning of the auxiliary line.

The mask layer should be located above the masked layer, and the shape of the elements in the mask layer is the shape of the picture we see below. Pay attention to the difference here. In many Flash works, people usually use matte to hide animations and elements that they don't want to display in the scene in the workspace. Masking is usually to create a layer, draw a figure larger than the scene, and leave a gap in the middle to show the layer below. The mask is located at the top of all layers, which is a normal layer, while the mask layer is only located above the mask layer, which is a special layer.

4. Seek the basic knowledge of 4. glitter

Landlord, if you use Toona sinensis arm studio or more advanced Toona sinensis arm Animate Pro animation software to do this animation, it will be much easier, because these professional animation software have camera function, which means you can do this camera lens motion animation just by moving the camera position in the software! Very easy!

However, since you don't know Flash at present and want to learn the basic operation of Flash, it is necessary to know it. Because of Flash animation experience, it is much easier to learn Toona sinensis Animate Pro, a truly professional animation software!

5.5 What are the common problems in getting started? Flash beginner?

4。

Why do objects always move in a straight line when they are animated along the trajectory? The center position of the first or last frame object is not on the track. There is a simple check method: you set the screen size to 400% or more to see if the circle in the middle of the graph is aligned with the motion trajectory.

5。 Why do objects always move in a straight line when doing closed trajectory animation? The teacher of South China Huian Animation Design Training School told you to try to get rid of the closed path.

6。 How to solve the speed problem in Flash? To modify & gt movies, just adjust the system frame rate (or Ctrl+M) after the text box, or shorten the frame moving distance.

7。 Why are the text buttons not flexible? When making a button, you don't specify the click area (that is, the trigger area of the button), especially when making a text button, you usually define a rectangle as the click area. If you don't define the click area, the system will use text as the trigger area of the button, which is naturally not very flexible to use.

The hit area is hidden and will not be displayed in the scene. .
