I am experienced. I just responded with about as much effort as you put in your own post asking for help.
Besides, there are an infinite number of ways to achieve what you want. Without seeing what code you wrote so far, it’s a bit like trying to read your mind and guess what the best solution should be.
Small advice for the future: You don’t want to know how to make an “arrest system” but instead…
Does anyone know how to make an arrest button pop up when in range of a character/NPC?
…this. Try to break down your problem/question as much as possible because no one here can answer how to make an arrest system for your special case but people can give you hints on how to approach the “show something when in range of an NPC” problem.
Well, maybe they do want to know how to make the whole system, including putting handcuffs on the npc and escorting them to the jail. We’ll likely never know
This guy is one of the few people I could find who is currently active and has been on the forum as me and was called inexperienced. The answer he gave is completely fair and exactly how I would do it. Are you new to code entirely and expect people on the forum to just write code for you or explain what every node is. You have to research yourself.
