I fixed this bug but it happens again

Does this happen consistently or only randomly?

3

randomly. It seems to me that this happens when players leave the game (I’m not sure)

if v.Character then
						local char = v.Character
						for o, p in pairs(char:GetDescendants()) do -- this is line 14
							if p:IsA("ProximityPrompt") and p.Name == "Arrest" then
								p.Enabled = true
							end
						end
					end

Can you share the full script? It seems that this is incomplete.

local plr = game.Players.LocalPlayer
local PickDebounce = false
local ArrestDebounce = false

coroutine.wrap(function()
	while wait(0.5) do
		local char = plr.Character or plr.CharacterAdded:Wait()
		if char then
			if plr.Character:FindFirstChild("Handcuffs") then
				for i,v in pairs(game.Players:GetChildren()) do
					if v ~= plr then
						if v.Character then
							for o,p in pairs(v.Character:GetDescendants()) do
								if p:IsA("ProximityPrompt") and p.Name == "Arrest" then
									p.Enabled = true
								end
							end
						end
						
					end
				end
			else
				for i,v in pairs(game.Players:GetChildren()) do
					if v.Character then
						if v ~= plr then

							for o,p in pairs(v.Character:GetDescendants()) do
								if p:IsA("ProximityPrompt") and p.Name == "Arrest" then
									p.Enabled = false
								end
							end
						end
					end
					
				end

	end

You may need to increase the wait.task() time as running a loop through all players every 0.5 seconds might be too frequent.

can you not change the variable names?

I did it to make it easier to understand when I was going through it, you’re welcome to change them back.

10

Because of this, the script does not work and I cannot figure out what names you chenged.

11

this is not a complete part of the script. where are more lines

12

That might be where the issue occurs then.

13

no errors, but the script stopped working completely

14

Move it to StarterCharacterScripts.

15

it was already there. before that, the script stopped working after the first arrest (all promps disappears), and now they don’t even appear

16

Try StarterPlayerScripts instead. Are you receiving any errors in console?
