Unity3d game development Animation class and animator class

Animation class
The animation component is used to play the animation. You can assign an animated clip to an animation component and control the animation playback from the script. The animation system in unity is based on weights and supports animation blending, overlay animations, animation blending, labeling and full control of all aspects of animation playback.
If you want to play a simple animation, You can use Animation.play; if you want to cross-fade between animations, you can use Animation.crossfade, or if you want to change the animation mode (loop, once, ping-pong), you can change the animation frame's WrapMode in the animated import settings, or change it at run time Animationst The value of Ate.wrapmode; Animationstate can be used to change the animation layer, modify the playback speed, and directly control the fusion and blending. Animations also support enumerations, so you can cycle "dog planing learning nets" between animationstates like this:

// reduce the playback speed of all animations for this character by half for (var state : animationstate in animation) { State . speed = 0.5 ; }

Variables variable
Clip's default animation clip.
playautomatically If the default animation is automatically played at the beginning
WrapMode what to do after the animation clip has finished playing
is isplaying playing any animations?
This [string name] returns the animation state named name.
Animatephysics If this option is turned on, the animation will be executed during the physical loop. This option is useful only when combined with a kinematic rigid body.
animateonlyifvisible If this option is turned on, unity may stop playing when it thinks the user won't see the current animation.

IsPlaying The animation named name is playing?
Play does not have any mix of playback animations.

Getclipcount gets the number of animated clips for the current animation.
Synclayer synchronizes the playback speed of a layer of animation.

Animation Playback and sampling
When you create an animation of 60 frames per second in 3ds Max or Maya, it is also a 60-frame animation when imported into unity. However, when the game is running, the frame rate is not constant. The frame rate will be faster on some faster PCs, and the frame rate will be different from the complexity seen on the camera at any point given. Basically this means that we can not assume the exact frame rate when the game is running. If there is a 60-frame animation, it should be back from a different frame rate, such as 56.18 fps, or 87.61fps, can be any point.
Unity's sampling animations at different frame rates are not their true frame rates. Fortunately, the animations on 3D computer graphics are not composed of separate frames, but are continuous curves. These curves are suitable for sampling at any point, not just those points of the original frame on the timeline. This means that when the game is running, the animation will look smoother and smoother at higher frame rates.
In the case of most exercises, the fact that unity sampling animations do not have to be connected in these variable frame rates is not what you imagine. However, if you have a game logic to judge the control animation of the coordinate properties, then you have to pay attention to. For example, if you have a 30-frame animation that is to rotate an object from 0-180 degrees, you want to know when the code goes to 90 degrees when the animation is halfway through, you should not add a conditional statement to determine if the rotation of the object is now 90 degrees. Because Unity's animated samples are based on the different frame rates of the game, it's time to judge when the rotation is below 90 degrees, and it happens when you're 90 degrees. If you need to know when to specify a point in the animation, you should use Animationevent instead.
To pay attention to the causal relationship on the variable frame rate, it is impossible for a playback animation to be sampled with wrapmode.once for the exact time of a previous frame. The animation frame on the game can be sampled after the animation is played, the time on the next frame will have an extra animation length, so close will not be sampled. If you really need a previous frame of animation to do the sampling, you need to wrapmode.clampforever. This way the animation will keep the last frame sampled until you stop playing the animation.
