unity3d:动画animator，AvatarMask，边走边攻击，单独设置run动画速度

本文主要是介绍unity3d:动画animator，AvatarMask，边走边攻击，单独设置run动画速度，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

分为3layer，run-idel层（layer0），攻击时上半身层（layer1），原地攻击层（layer2），其中layer1，layer2里面完全复制的动画状态机
在这里插入图片描述

其中layer1设置mask，屏蔽下半身动作
在这里插入图片描述

在移动时切换layer1，layer2的权重，同时只存在一个为0，一个为1
