目标:使用审核控件从一个场景更改为另一个场景。
问题:在HoloLens仿真器中启动应用程序时,会打开第一个场景。当说"下一步"时,HoloLens确实识别了句子,但sendMessage没有打开OnNextStep()
功能。
感谢您的帮助! :)

答案 0 :(得分:4)
Unity的SendMessage
函数在调用函数时区分大小写。
您的函数名称为OnNextstep
,但您正在调用OnNextStep
:
SendMessage("OnNextStep", SendMessageOptions.DontRequireReceiver);
注意大写和非大写“S”。修复此问题,假设存在其他隐藏问题,则应解决您的问题。
注意强>:
避免在Unity中使用SendMessage
。如果要从另一个脚本调用函数,请使用GameObject.Find
查找 GameObject 然后GetComponent
以获取该脚本然后调用其函数。您也可以使用events and delegates执行此操作。
