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)

#4 
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
#5

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

#6 
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

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?

#9

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?
