A stop sign detector to see if you have clicked the stop sign! Yes, this works, all right! Feel free to use this in your projects (just credit me for this)! Just please note that pressing the stop sign multiple times does break the detector. To have it detect again, press the green flag first.
IMPORTANT NOTE: Any games that utilize the "timer" block will be messed up if you use this. Please check this and use it at your own risk.
