Try 'if inkey$()="k" then print "K was pressed"'

Hope this helps

Whatever I did I didn't do it!

You can also use scancodes, codes that define what key is pressed, which works for every key on the board. This even includes Print Screen, all 3 locks and Pause.

This has "Fiasco" written all over it.

If your going for in game responsive controls go with scancode() or keystate(). I think keystate() is better again for controls but I'm not sure.

Keystate() is used if you want to check for a specific key, and so is useful for game controls. Scancode() is used if you want to see which key the user presses, and so is useful for a text editor or something.

to find the scancodes just run this and note down what keys do what or make it into a little function to see it in game as a debug screen

scancode() is used to check one key at a time.
keystate() can be used for multiple keypresses.

use indi's code snippet to find the scancode() and if you want to check more than one key at a time then put the scancode() between the ()s in keystate()

and inkey() can be used to find the "text" version of whats being pressed...if k is pressed then k will appear BUT if SHIFT AND THEN k is pressed the K (not k) will appear

There is a number for each key.
The "(" and ")" in keystate should be the scancode.
To check for the Return key use this:


To find other scancodes use indi's snippet. If you press return it should print 10. (Not testet)
