鼠标点击地面人物自动走动(也包含按键wasd&space控制)

在漫游游戏中常用的功能就是人物在场景中行走，必要的功能就是鼠标点击地面人物就朝着那个方向行走，键盘方向键前后左右也能控制人物的行走和跳跃，在官方自带的第三人称视角中做了一点修改，官方自带的ThirdPersonController中的摄像机自动指向人物的背面，这样不能看到人物的正面或者侧面，对ThirdPersonController脚本做了修改之后，可以旋转摄像机的视角，可以摄像机跟随，类似smoothfollow的功能。

值得注意提醒的一个，就是动画系统，选择老版本的动画系统，不然会提示找不到模型，因为脚本中用的是老版本的动画系统的代码。

一、效果图

1.鼠标点击地面人物朝着点击的点前进
2.按住wasd和space键也能控制人物的动作

二、大概步骤

1.创建一个plane，设置层为Terrain，因为后面要判断是否点击的是这个层

void Update () {

MouseDownMover();

}

public void MouseDownMover() {

if(Input.GetMouseButtonDown(0)) { //如果左击

LayerMask layerMaskPlayers = 1 << LayerMask.NameToLayer("Terrain");

Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);

RaycastHit hit;

if (Physics.Raycast(ray, out hit,600,layerMaskPlayers.value)) {

point = hit.point;

Instantiate(clickPont, point, transform.rotation);

TimeRealtimeSinceStartup();

}

}

}

2.准备好人物模型，并且将三个脚本拖放到人物上，并且将动画文件也拖放好，记得看前面提醒哦！

1.ThirdPersonCamera(相当于smoothflow)
