Unity新手开发游戏遇CS1022错误，代码调试无果求助

错误原因及修复点 #

你的代码存在多处语法错误，导致编译器无法正确解析类结构，具体问题如下：

• 方法定义语法错误：代码中private void update;是非法写法，Unity的Update方法正确定义应为private void Update()（注意大写U，使用括号而非分号）。
• 代码块位置错误：Update方法结束后，有一段if (isJumping)代码直接暴露在类作用域中，C#不允许类作用域下存在独立执行代码块，必须将其移入方法内部。
• 大小写错误：camera.main.enabled = false;中的camera需改为大写Camera，Unity的Camera类为大写开头。
• 重复代码冗余：存在两段完全相同的if (isJumping)代码块，需移除多余的那一段。
