Hello every body.
I would be thankful if you could help me.
I am trying to run Binflow ,However there are some errors :(LIGGGHTS (Version LIGGGHTS-PUBLIC 3.3.1, compiled 2016-01-14-14:02:34 by kloss, git commit 9b1fc57b77c483deaf2c0a6c69241c5d4f91e3c2 based on LAMMPS 23 Nov 2013)

Thank you so much Daniel .
I have modified the code but still there is an error.(ERROR: Unknown command: overlapcheck yes vel constant 0 0 -1 region factory ntry_mc 10000 (/build/liggghts-QCz4in/liggghts-3.3.1+repack1/src/input.cpp:256)

Rocket Gamble is not your typical casino game. While it shares some similarities with games like slots or roulette, it introduces an element of strategy and timing that sets it apart. The premise is simple: players place bets on the trajectory of a virtual rocket, which ascends at a rapid pace. The longer the rocket stays in the air, the higher the potential payout. However, there's a catch – the rocket can explode at any moment, and if it does, players lose their bet.
