如何在unity中用C#调用ui按钮中的键码？

Question

这是脚本......在开始的几行你可以看到键码的用法。我想为安卓系统添加UI按钮，当用户点击该按钮时，它将作为Keycode.A或任何我想要的Keycode。当用户点击该按钮时，它将作为Keycode.A或任何我想要的Keycode，我不想改变脚本。任何解决方案？我是完全的初学者，我不太了解这个代码，所以不想改变它。我得到了它的免费资产2D游戏套件，其中字符艾伦移动与PC控制。我只想把人物控制从PC改为ui按钮。请帮助我，如果我必须改变脚本，我会得到很多错误，我不能处理，所以请帮助。

这是不可能的。我建议你在按钮被按下的时候直接调用你想要的功能。
