Animation Clip关键函数

【AnimationClipSettings】

设置clip loop

    AnimationClipSettings setting = AnimationUtility.GetAnimationClipSettings(clip);
    setting.loopTime = true;

[tip: 通过clip.wrapMode无法设置clip 的类型]

【AnimationUtility】

clip curve 曲线key 帧数，
一般推荐预设帧数，然后设置关键帧的时间

CODE：

    var rate =30
      clip.frameRate =rate
     //
     var keyFrames = new Keyframe[8];
     keyFrames[0] = new Keyframe(0, 0);
     keyFrames[1] = new Keyframe((float)50 / rate , 0);
     var idleCurve = new AnimationCurve(keyFrames);
     //帧左侧曲线状态
     AnimationUtility.SetKeyLeftTangentMode(idleCurve, 0, AnimationUtility.TangentMode.Linear);
     AnimationUtility.SetKeyLeftTangentMode(idleCurve, 1, AnimationUtility.TangentMode.Linear);
     //帧右侧曲线状态
     AnimationUtility.SetKeyRightTangentMode(idleCurve, 0, AnimationUtility.TangentMode.Linear);
     AnimationUtility.SetKeyRightTangentMode(idleCurve, 1, AnimationUtility.TangentMode.Free);
     //设置一条轨道
     clip.SetCurve(relativePath, typeof(SkinnedMeshRenderer), propertyName, idleCurve);

【AnimatorController】

Animator Controller 创建layer数据。因为layer是struct 结构，初始化layer 信息需要再次赋值。

               var ac = new AnimatorController();
               ac.layers = null;
                ac.AddLayer("Default");
                ac.AddLayer("Face");//表情层
                //
                ac.parameters = null;
                var layers = ac.layers;
                //Default
                layers[0].defaultWeight = 1;
                //FACE
                layers[1].defaultWeight = 1;
                ac.layers = layers;
