unity 3d生存游戏ui制作

Day 1

操作

创建Terrain作为基础地形

创建一个空对象，命名为Player

对Player对象

创建一个Cylinder作为玩家人物，移除原有碰撞体，使用Character Controller（该组件加在Player上）

将主视角摄像机移动到Player下，做第一视角游戏

添加PlayerMovement与Mouse Movement（其中PlayerMovement存在bug，在开始游戏的时候如果大幅度移动鼠标会导致人物亲吻地面）

创建空对象GroundCheck并至于玩家脚底，保证人物拥有落地检测（人类暂时不应该二连跳）

注意：记得给地面Terrain放置到Ground层，并将落地检测的层也设置为Ground

代码

         isGrounded = Physics.CheckSphere(groundCheck.position, groundDistance, groundMask);
 
         if (isGrounded && velocity.y < 0)

         controller.Move(move * speed * Time.deltaTime);
 
         //如果在地面上，就可以跳（不许连跳）（以后多加个能力参数来解锁连跳吧）
         if (Input.GetButtonDown("Jump") && isGrounded)
         {
             //the equation for jumping
             velocity.y = Mathf.Sqrt(jumpHeight * -2f * gravity);
         }
 
         velocity.y += gravity * Time.deltaTime;

         //控制以x轴为轴心的旋转（抬头/低头）
         xRotation -= mouseY;
 
         //保证抬头/低头幅度不超过90°
         xRotation = Mathf.Clamp(xRotation, -90f, 90f);
 
         //控制以y轴为轴心的旋转（左右看）
         YRotation += mouseX;
 
         //applying both rotations
         transform.localRotation = Quaternion.Euler(xRotation, YRotation, 0f);//不太懂，先用着
 
     }
 }
