方式一：通过读取标准avatar.json（可参考demo中assets目录avatar目录下的配置）来获取， 推荐使用该方式 //解析avatar.json val avatarInfo =FUSceneKit.getInstance().decodeAvatarFormJson(avatarJson) 方式二：通过代码生成要添加的道具列表和配置 //身上的道具列表（身体、衣服、五官等） val bundles = listOf( "GAssets/AsiaMale/head/BaseModelAmale_head.bundle", "GAssets/AsiaMale/body/BaseModelAmale_body.bundle", "GAssets/AsiaMale/brow/brow000.bundle", "GAssets/AsiaMale/hair/hair001.bundle", "GAssets/AsiaMale/cloth/lower_inner/shorts/shorts001.bundle", "GAssets/AsiaMale/cloth/upper_inner/shirt/shirt003.bundle", "GAssets/AsiaMale/face_components/eye/eye201a.bundle", "GAssets/AsiaMale/face_components/face/face201b.bundle", "GAssets/AsiaMale/face_components/mouth/mouth201a.bundle", "GAssets/AsiaMale/face_components/nose/nose201b.bundle" ) .....骨骼捏型，道具颜色配置类似这里就不一一列举了，可参考avatar.json自行实现
（2）将道具和配置添加到avatar对象中去（这里只拿avatar.json方式举例）
//解析avatar.json
val avatarInfo =FUSceneKit.getInstance().decodeAvatarFormJson(avatarJson)
/** 添加avatar.json中配置的bundle道具。*/
avatarInfo?.bundles?.apply {
controlConfigBundle?.let { controlConfig ->
/** 由于可能存在套装bundle（空bundle，内部记录了真实道具列表）
，所以需要通过读取bundle的meta信息来校验得到道具的完整列表， 在进行verifyAvatarJson校验之前需要确保完成了初始化AvatarDecoder，和待校验bundle的下载**/
FUAvatarDecoderHelper.getInstance().verifyAvatarJson(this, controlConfig)
?.let { componentList ->
if (componentList.isNotEmpty()) {
needCheckBundles.addAll(componentList)
val countDownLatch = CountDownLatch( componentList.size)
//拿到完成道具列表后，再次校验并下载可能本地不存在的道具
componentList.forEach {sourceId ->
FUResourceHelper.getSourceBeanRemote(sourceId,
object : OnLoadRemoteSourceListener {
override fun onError(code: String, message: String) {
countDownLatch.countDown()
}
override fun onFinish(fileSourceBean: FileSourceBean) {
countDownLatch.countDown()
getFUBundleData(fileSourceBean)?.let { component ->
avatar.addComponent(component)
}
}
},resourceType)
}
countDownLatch.await()
} else {
FULogger.d(TAG, "verifyAvatarJson but componentList is empty")
}
}
}
}
//添加道具颜色配置
avatarInfo?.let {
it.colorName.forEachIndexed { index, name ->
it.colorData[index]?.let { color ->
avatar.color.setColor(name, color)
}
}
}
//添加骨骼捏型配置
avatarInfo?.let {
it.deformationName.forEachIndexed { index, name ->
it.deformationData[index].let { value ->
avatar.deformation.setDeformation(name, value)
}
}
}
//添加动画graph配置文件
FUFileUtils.readContentByPath("graph/animGraph.json")?.let {
animationGraph.setAnimationGraph(it)
}
FUFileUtils.readContentByPath("graph/animLogic.json")?.let {
animationGraph.setAnimationLogic(it)
}
//配置动画
avatar.animation.playAnimation(FUAnimationBundleData("GAssets/animation/AsiaMale/common/ani_ptag_amale_huxi.bundle"))避免avatar出现裸体，兜底逻辑
添加和替换道具时进行道具校验，处理套装bundle情况。

}//设置bundle背景 scene.setBackground(FUBundleData(sceneResourceConfig.getScenePath())) //设置color背景 scene.setBackgroundColor(FUColorRGBData(255,255,255,255))
//设置灯光 scene.setLightingBundle(FUBundleData(lightBundlePath))
//这里的相机bundle可以是融合相机，也可以是普通相机 scene.cameraAnimation.setAnimation(FUAnimationBundleData(sceneDefaultCameraPath))
：方法即可实现相机的切换，cameraIndex即为内部相机的下标，type 为切换动效类型，transitionTime为动效过度时间scene.cameraAnimation.setAnimationModuleIndex( cameraIndex, type = FUCinemachineBlendTypeEnum.EASE_IN_OUT, transitionTime = 0.5f )
//重新为场景 scene加载新的相机位 即可实现普通相机的切换。 scene.cameraAnimation.setAnimation(FUAnimationBundleData(newCameraPath))
//预加载动画道具 avatar.animation.addAnimation(FUAnimationBundleData(animationBundlePath)) //播放动画 avatar.animation.playAnimation(FUAnimationBundleData(animationBundlePath))
