我在 Unity3D 中有一个应用程序(充当服务器),它从具有以下结构的外部应用程序(单个客户端)接收消息:
数字(浮点数) 数字(浮点数) 数字(浮点数)
前两个数字代表局部位置(x,z 轴),最后一个数字代表旋转值(y 轴)。
目标是使用此数据更新游戏场景中的 Camera 游戏对象位置(使用 LoadPositions 方法)。从我读过的内容来看,在 Unity 的主线程之外操作游戏对象是不可能的。
话虽如此,我如何在 Unity 主线程之间进行切换,以便我既可以收听消息又可以更新游戏对象的位置。此外,是否有人碰巧知道 Unity 中一个简单的 TCP 服务器的工作示例,而无需求助于线程?
