我正在使用unity3D引擎来创建一个涉及汽车的游戏

在执行控件时，遇到以下错误。

Assets/Car/Scripts/NewBehaviourScript.js(78,22): UCE0001: ';' expected. Insert a semicolon at the end.

Assets/Car/Scripts/NewBehaviourScript.js(78,10): BCE0044: expecting (, found 'ShiftGears'.

Assets/Car/Scripts/NewBehaviourScript.js(79,9): BCE0043: Unexpected token: if.

Assets/Car/Scripts/NewBehaviourScript.js(79,41): UCE0001: ';' expected. Insert a semicolon at the end.

这些错误通常不会统一出现在sxripting中，这是我第一次遇到它。这是我的代码

在座的任何人都可以帮助我进行调试吗？多谢。
