MultiPlayer 注意点

本篇是对项目的一些记录

 public void Move(float horizontal, float vertical){Vector3 movement = new Vector3(horizontal, 0f, vertical);movement = movement.normalized * speed*0.025f;// * Time.deltaTime;PlayerRigidbody.MovePosition(transform.position + movement);}

注意这里的不能乘以,因为要保证每一帧走的距离是一样的而不是随着帧率改变！！

否则再不同客户端会看到每一次Input在不同客户端上的距离不同（不同客户端的帧率不同），造成不同步！

.和.的区别：

.

n;

The of the .

. you to get and set the of a using the . If you the of a ., the will be after the next step. This is than the ., as the will cause all to their to the .

If you want to move a use , which takes into .

比如：

.cs

 if (msg.msg_type == (int)RequestType.INPUT){InputMessage Input_msg = msg as InputMessage;viewPlayer.get_Rigidbody().position = new  Vector3(viewPlayer.get_Rigidbody().position.x,Input_msg.moving_y, viewPlayer.get_Rigidbody().position.z);viewPlayer.Move(Input_msg.moving_x, Input_msg.moving_z);}

如果使用：

.. = new (...x,., ...z);

如果环境复杂（有很多）就会卡住很久！

例如这种环境：

因为如果使用., 将导致所有附加的重新计算它们相对于刚体的位置。

例如：简单的环境中：

 viewPlayer.transform.position = new Vector3(viewPlayer.transform.position.x, Input_msg.moving_y, viewPlayer.transform.position.z);

用完全没有问题

.在下一次时就会改变。

最终的设置和设置

代码更改的地方：

. 冻结旋转

: bool

描述

控制物理是否改变物体的旋转。

If is , the is not by the . This is for first , the needs full of the using the mouse.

如果被启用，旋转不会被物体模拟修改。这对于创建第一人称射击游戏时是很有用的，因为玩家需要使用鼠标完全控制旋转。

using UnityEngine;
using System.Collections;public class example : MonoBehaviour {public void Awake() {rigidbody.freezeRotation = true;}
}

Input.

You need to call this from , since the state gets reset each frame. It will not true until the user has the mouse and it again. are 0 for the (often the left ), 1 for , and 2 for the .

using UnityEngine;
using System.Collections;// Detects clicks from the mouse and prints a message
// depending on the click detected.public class ExampleClass : MonoBehaviour
{void Update(){if (Input.GetMouseButtonDown(0))Debug.Log("Pressed primary button.");if (Input.GetMouseButtonDown(1))Debug.Log("Pressed secondary button.");if (Input.GetMouseButtonDown(2))Debug.Log("Pressed middle click.");}
}

.()失效的原因：

Drag、 Drag设成了无穷大，所以给推力时动不了，还要记得所有的碰撞要放在里！

把Drag、 Drag改小就好

穿过地面的原因：（ 和地面都添加了还时穿过了。。）

不能用.()！！必须通过让运动！，还有所有的运动都要放在()里！！！

让贴着地面走

只需要给,y轴方向一个速度就行！和,一样的道理，相当于给一个重力，并不需要投一条射线再判断交点（卡死 = =）

鼠标的位置，就是最终的位置！而不是旋转差！这样的好处是鼠标定在哪，的旋转角度就固定在哪，否则，若是旋转差的话，会出现鼠标不能与枪口一致的情况
