Hello Everyone! I need help with packets. This may use NMS (which I'm fine with), or maybe just the api. Can someone tell me how I can tell when someone middle clicks (pick block), and have a way to cancel it. Also, I am am essentially trying to when someone middle clicks in survival mode, I will run some code on the block their looking at. Bottom Line: I need a way to detect when a survival player middle clicks (and maybe even a way to cancel it). This may help Thanks so much! - Blue Bump.
