如何检测是否按下了变量的键？

Question

I´m making a game that creates a random key that you have to press. I have an array with the letters from where it takes one randomly. I want to detect if the key is pressed so I did this:

if (Input.GetKey(KeyCode.lettre))

but with letter = "A" for example, it will do this:

if (Input.GetKey(KeyCode."A"))

How do I get this?

if (Input.GetKey(KeyCode.A))

Answer 1

GetKey can be called with a string, so you could just do:

if (Input.GetKey(letter)) // assuming letter is a string

You might need letter to be lowercase for this to work. See the list of key names here .

Alternatively, you could use Enum.Parse to convert your string to an enum value:

if (Input.GetKey((KeyCode)Enum.Parse(typeof(KeyCode), letter)))
