How do I get the keyCode?

Processing Coding Questions
1

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?

2

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

3

I need to get if any key on the keyboard is pressed.

4

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

5

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

6

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

7

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

8

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:

println( (int) key );

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

Try this sketch:

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.
