I want to make a KeyHandler class to make it so I can press multiple keys, but I don’t know how to get the ASCII integer value for every key, how do I do this?

Why do you need the ascii code? What are some example keys that you’re trying to use?

I’m not sure I understand what you’re asking- doesn’t the `keyCode` variable already give you that?

It only gives coded keys like shift, control, ect.

Have you tested that theory? The `keyCode` variable prints out ascii values for all of the keys on my keyboard.

Yup. I have. Every other key prints out 0.

This is also for that 3D engine!

Hmm, interesting. The `keyCode` works fine for me on Windows. Maybe it’s a platform-specific thing.

The `key` variable contains the character that was typed. You can probably just cast to `int` to get the ascii code:

```auto
println( (int) key );

```

I’ll try that, but, I AM using Windows! Hmmm…

Try this sketch:

```auto
void draw(){}

void keyPressed(){
 println("key: " + key);
 println("int key: " + (int) key);
 println("keyCode: " + keyCode);
 println();
}

```

For me, this prints out reasonable values for every key on my keyboard.
