Unity 网络转换问题 - 客户端在错误位置生成对象
Unity network transform problem - Client spawning objects at wrong location
我正在为 Unity 开发一款类似 Fortnite 的游戏。
玩家生成，可以生成方块来制作 "base"。
一切都在单声道中运行良好，但我在网络方面遇到了一个奇怪的问题。在服务器上，我的播放器可以在客户端上根据 Raycast 生命值完美地生成立方体，即使玩家是 Player 预制件的克隆，生成的对象总是在世界原点结束，而不是 Raycast 生命值 -或者 - 如果我从包含 Raycast 信息的播放器脚本中删除 if (!isPlayLocal) {return;}，则立方体生成不准确并且没有相应的 material。
我会尝试找出代码，以便我可以将它放在这里，但我想它可能有很多东西。
在生成预制件上选中本地玩家身份验证，并且所有预制件都已在网络管理器中注册。

[Command]
public void CmdPlaceBlock()
{
GameObject newBlock = Instantiate(blockPrefab, buildPos, Quaternion.identity);
Block tempBlock = bSys.allBlocks[blockSelectCounter];
newBlock.name = tempBlock.blockName + "-Block";
newBlock.GetComponent<MeshRenderer>().material = tempBlock.blockMaterial;
NetworkServer.SpawnWithClientAuthority(newBlock, connectionToClient);
}
没有参数。
一个Command在客户端被调用但是在服务器
执行
=> 使用 Server!
的局部变量
例如由于
，buildPos 在服务器上将始终具有默认值 0,0,0
if(!isLocalPlayer) return;
稍后的行
buildPos = new Vector3(Mathf.Round(point.x), Mathf.Round(point.y), Mathf.Round(point.z));
从不在服务器上执行。这同样适用于例如blockSelectCounter 以及您的 CmdPlaceBlock 可能依赖的其他值。
解决方案
您应该将客户端的 buildPos 值（以及客户端和服务器上所有其他不同的值）传递给服务器命令，以便服务器知道新对象应该放置在哪个正确位置：
//...
if (Input.GetMouseButtonDown(0))
{
CmdPlaceBlock(buildPos);
}
//...
[Command]
public void CmdPlaceBlock(Vector3 spawnPosition)
{
GameObject newBlock = Instantiate(blockPrefab, spawnPosition, Quaternion.identity);
Block tempBlock = bSys.allBlocks[blockSelectCounter];
newBlock.name = tempBlock.blockName + "-Block";
newBlock.GetComponent<MeshRenderer>().material = tempBlock.blockMaterial;
NetworkServer.SpawnWithClientAuthority(newBlock, connectionToClient);
}
我只添加了一个位置示例，知道它在客户端和服务器上总是不同的。但它也可能适用于您的其他价值观，例如blockSelectCounter.
对所有必须是客户端的值而不是服务器的值进行此更改。
请注意，网络方法之间可以传递的类型是有限的！你不能通过例如任何组件引用。
The allowed argument types are;
- Basic type (byte, int, float, string, UInt64, etc)
- Built-in Unity math type (Vector3, Quaternion, etc),
- Arrays of basic types
- Structs containing allowable types
- NetworkIdentity
- NetworkInstanceId
- NetworkHash128
- GameObject with a NetworkIdentity component attached.
其他提示
为了可读性和行数，你应该改变一些东西，例如
if (buildModeOn)
{
// weapon.SetActive(false);
crossHairOn = true;
}
else
{
// weapon.SetActive(true);
crossHairOn = false;
}
简单
// weapon.SetActive(!buildModeOn);
crossHairOn = buildModeOn;
并检查 bools 不像
if (isLocalPlayer == false)
而是
if(!isLocalPlayer)
它只是 reads/writes 更容易 ;)
