骨骼动画

骨骼动画资源需要用导出插件导出，导出之后可以用以下方式进行使用

// 按1 2 3 4键 切换动画
protected onKeyDown(e: egret3d.KeyEvent3D) {
    switch (e.keyCode) {
        case egret3d.KeyCode.Key_1:
            if (this.role) {
                this.role.animation.play("Idle");
            }
            break;
        case egret3d.KeyCode.Key_2:
            if (this.role) {
                this.role.animation.play("Run");
            }
            break;
        case egret3d.KeyCode.Key_3:
            if (this.role) {
                this.role.animation.play("Attack1");
            }
            break;
        case egret3d.KeyCode.Key_4:
            if (this.role) {
                this.role.animation.play("Death");
            }
            break;
    }
}

// 加载资源完成后 创建骨骼动画
protected createSkeletonAnimation() {
    // 加载完成后用url查找资源 
    var geo: egret3d.Geometry = this.queueLoader.getAsset("resource/doc/ganning/Ganning.esm");
    var clip0: egret3d.SkeletonAnimationClip = this.queueLoader.getAsset("resource/doc/ganning/Idle.eam");
    var clip1: egret3d.SkeletonAnimationClip = this.queueLoader.getAsset("resource/doc/ganning/Run.eam");
    var clip2: egret3d.SkeletonAnimationClip = this.queueLoader.getAsset("resource/doc/ganning/Attack1.eam");
    var clip3: egret3d.SkeletonAnimationClip = this.queueLoader.getAsset("resource/doc/ganning/Death.eam");
    var textures: egret3d.ITexture[] = [];

    textures[0] = this.queueLoader.getAsset("resource/doc/ganning/Ganning.png");
    textures[1] = this.queueLoader.getAsset("resource/doc/ganning/Ganning_f.png");
    textures[2] = this.queueLoader.getAsset("resource/doc/ganning/Ganning_Weapon.png");

    // 给每个动画指定名字 用于动画切换使用
    clip0.animationName = "Idle";
    clip1.animationName = "Run";
    clip2.animationName = "Attack1";
    clip3.animationName = "Death";

    // 创建Mesh
    var mesh: egret3d.Mesh = new egret3d.Mesh(geo, new egret3d.TextureMaterial());
    this.role = mesh;
    for (var i: number = 0; i < geo.subGeometrys.length; ++i) {
        var mat: egret3d.MaterialBase = mesh.getMaterial(i);
        if (!mat) {
            mat = new egret3d.TextureMaterial();
            mesh.addSubMaterial(i, mat);
        }

        mat.diffuseTexture = textures[i];
    }

    mesh.animation.skeletonAnimationController.addSkeletonAnimationClip(clip0);
    mesh.animation.skeletonAnimationController.addSkeletonAnimationClip(clip1);
    mesh.animation.skeletonAnimationController.addSkeletonAnimationClip(clip2);
    mesh.animation.skeletonAnimationController.addSkeletonAnimationClip(clip3);
    mesh.animation.play("Idle");

    this.view.addChild3D(mesh);
    // 监听动画播放完成事件 
    mesh.animation.skeletonAnimationController.addEventListener(egret3d.AnimationEvent3D.EVENT_PLAY_COMPLETE, this.onPlayComplete, this);
    mesh.animation.skeletonAnimationController.addEventListener(egret3d.AnimationEvent3D.EVENT_FRAME_CHANGE, this.onPlayChange, this);

}

// 播放完成事件 如果是循环动画 完成一次会触发一次
protected onPlayComplete(e: egret3d.AnimationEvent3D) {
    var skeletonAnimation: egret3d.SkeletonAnimation = e.target;
    console.log("onPlayComplete:" + skeletonAnimation.currentAnimName);
}

// 换帧事件
protected onPlayChange(e: egret3d.AnimationEvent3D) {
    var skeletonAnimation: egret3d.SkeletonAnimation = e.target;
    //console.log("onPlayChange:" + skeletonAnimation.currentAnimName);
}
