Player移动:
public float speed = 6f;
Vector3 movement;
Rigidbody playerRididbody; void FixedUpdate () {
float h = Input.GetAxisRaw("Horizontal");
float v = Input.GetAxisRaw("Vertical");
Move(h, v);
Animating(h, v);
}
void Move(float h, float v) {
movement.Set(h, 0f, v);
movement = movement.normalized * speed * Time.deltaTime;
playerRididbody.MovePosition(transform.position + movement);
}
通过h和v的值判断Player是否移动
void Animating(float h, float v) {
bool walking = h != || v != ; //判断Player是否移动
anim.SetBool("IsWalking", walking);
}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
int floorMask;
float camRayLength = 1000f;
同时还要获取Floor层
floorMask = LayerMask.GetMask("Floor");
//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。
void Truing() {
Ray camRay = Camera.main.ScreenPointToRay(Input.mousePosition);//返回一条射线
RaycastHit floorHit;
if (Physics.Raycast(camRay, out floorHit, camRayLength, floorMask)) {
Vector3 playerToMouse = floorHit.point - transform.position;
playerToMouse.y = 0f;
Quaternion newRotation = Quaternion.LookRotation(playerToMouse);
playerRididbody.MoveRotation(newRotation);
}
}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。 |
