By this, I mean the kind of keystrokes you'd have in a fighting game. Effectively detects you pressing multiple keys quickly to allow for things like dashing by double tapping or combos. I'm using it in a game of mine. Not case sensitive, since I'm only making it do what I need for my game. Keystroke window(time after pressing a key before your stroke ends) is only 0.5 seconds, so you must be quick. You can change this and it will still work. The RunKeystroke block is empty because in the detector, there isn't anything I want it to do once I've completed my keystroke. How it normally works is once its realized that you've stopped pressing keys, it runs whatever you want that keystroke to do, though it may be difficult to set up a lot.
Please give credit if you use this, as it took some time to try and come up with a script that works for this purpose.
