Recently I had needed a way to determine whether any key was pressed on the keyboard. This was because any key could potentially be used as an event trigger, and I didn’t want to assume anything about what those keys might be.
Without this check, the other safest way was to constantly execute the relevant methods, which may lead to reduced performance given a sufficient number of events on the map. Then I remembered there was a keyboard script available, which showed how to check the state of every key.
Using this idea, I could simply check if any of the keys were pressed, and set a flag as needed, and then provide that as a convenient script call.
Script: download here
In the script editor, place this script below Materials and above Main
To check whether any key is being pressed, use the script call
Which will return true if any keys are being pressed, and false otherwise.
This may not work for input devices other than the keyboard.
