小白的Unity5之路(一)

Player移动:

 1 public float speed = 6f;
 2 Vector3 movement;
 3 Rigidbody playerRididbody;
 4 
 5 void FixedUpdate () {
 6         float h = Input.GetAxisRaw("Horizontal");
 7         float v = Input.GetAxisRaw("Vertical");
 8         Move(h, v);       
 9         Animating(h, v);
10 }
11  void Move(float h, float v) {
12         movement.Set(h, 0f, v);
13         movement = movement.normalized * speed * Time.deltaTime;
14         playerRididbody.MovePosition(transform.position + movement);
15    }

 

通过h和v的值判断Player是否移动

1 void Animating(float h, float v) {
2 
3         bool walking = h != 0 || v != 0;   //判断Player是否移动
4 
5         anim.SetBool("IsWalking", walking);
6     }

 

Player跟随鼠标旋转:

首先建立一个面片作为地板(Floor)层,Layer也要设置成Floor.

然后删除地板的Mesh Renderer组件

 

 

 

 1 int floorMask;
 2 
 3   float camRayLength = 1000f;
 4 
 5 同时还要获取Floor层
 6 
 7  floorMask = LayerMask.GetMask("Floor");
 8 
 9  //Camera.main.ScreenPointToRay方法向某位置发射一条射线，射线与地面碰撞体产生碰撞。取得碰撞点，然后旋转Player。
10 
11     void Truing() {
12 
13         Ray camRay = Camera.main.ScreenPointToRay(Input.mousePosition);//返回一条射线
14 
15         RaycastHit floorHit;
16 
17         if (Physics.Raycast(camRay, out floorHit, camRayLength, floorMask)) {
18 
19             Vector3 playerToMouse = floorHit.point - transform.position;
20 
21             playerToMouse.y = 0f;
22 
23             Quaternion newRotation = Quaternion.LookRotation(playerToMouse);
24 
25             playerRididbody.MoveRotation(newRotation);
26 
27         }
28 
29 }

 

 

 

 

Raycast (ray : Ray, out hitInfo : RaycastHit, distance : float = Mathf.Infinity, layerMask : int = kDefaultRaycastLayers) 

参数

 

ray

射线的起点和方向

hitInfo

如果返回true，hitInfo将包含碰到器碰撞的更多信息。

distance

射线的长度

layerMask

只选定Layermask层内的碰撞器，其它层内碰撞器忽略。
