。 我决定编写一个自定义脚本，不必一直使用mathf.lerp，但是它似乎无法正常工作，我也不知道为什么。
这是您要做的测试
1）创建一个新场景并在其中添加一个新立方体
2）将“ call_timer.cs”添加到多维数据集
3）按播放
4）如果您按“ o”，则“ molo”的值将从0秒增加到2秒7秒
5）如果按“ u”，则“ mola”的值将在6秒内从0增加到
6）那么我的问题在哪里，或者错误在哪里？：在控制台中，我可以看到该值在增加，但是在“检查器”中该值仍然为0，而我没有确切知道为什么

感谢您抽出宝贵的时间来学习它。
答案 0 :(得分：1)
简而言之，您实际上从未更改过Inspector公开的值。并且您只记录参数或本地变量，而不记录实例字段（Inspector公开的实例字段）。
您的mola和molo是原始类型，并按值作为参数传递。更改函数中参数的值不会更改用于调用该函数的变量的值。
请参见ref关键字https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/ref
