Unity：新的 InputSystem 和旧的 EventSystem 之间的冲突

Question

使用新的输入系统时。如果我将 Canvas 组件添加到我的场景中，它会自动带来旧的 EventSystem，并且我在控制台中看到此错误：

InvalidOperationException: You are trying to read Input using the UnityEngine.Input class, but you have switched active Input handling to Input System package in Player Settings.

Answer 1

看起来解决方案在 Inspector 中的自动更新按钮中：

Answer 2

您可能尝试导入新的输入系统包以兼容多种输入设备。这些类型的错误是由于新旧输入系统包之间的冲突造成的，并且可能在最新更新中得到解决。 要解决此问题，请转到 Edit -> Project Settings->Player->Other Settings 下 strong>配置是主动输入处理选项。选择两者。 Unity 将重新启动。现在你的问题应该解决了。您将能够同时使用旧的输入系统包和新的输入系统包。 干杯。 附言

去编辑->播放器->其他设置->配置最后一个选项->你可以选择输入系统然后unity会重启然后它不应该抛出错误:)
