Health-hack (bulletproof) detector - ******* video
Estimated reliability:
Calibration:
1. Increase delayer time in case if there are false detections
2. Evaluate if there are false detections by spectating each detected player
3. Repeat step 1 until there is no false detections
Individual script modification needed:
-afk check has to be added
-number of hits without losing health needed to take action(after calibration)
-final action (after calibration)
No-spread detector - ******* video
It's not effective if the player is waving the gun around.
