Why does this coin collect script that I inserted in the coin not work?
In my game, I inserted collectable coins, but for some reason, the script is not working and I get the message:
18:10:42.625 - Workspace.Coin.CollectScript:8: attempt to index local 'player' (a nil value)
Does somebody know what this means and how I can fix it?
This is the script inside the coin:
01 | local db = true |
02 | script.Parent.Touched:Connect(function(hit) |
03 | if hit.Parent:FindFirstChild("Humanoid") == nil then |
04 | if db == true then |
05 | db = false |
06 | script.Parent.Transparency = 1 |
07 | local player = game.Players:GetPlayerFromCharacter(hit.Parent) |
08 | player.leaderstats.Coins.Value = player.leaderstats.Coins.Value + 1 |
09 | script.Sound.Play() |
10 | wait(60) |
11 | script.Parent.Transparency = 0 |
12 | db = true |
13 | end |
14 | end |
15 | end) |
and this is the script in the workspace:
1 | game.Players.PlayerAdded:Connect(function(plr) |
2 | local f = Instance.new("Folder", plr) |
3 | f.Name = "leaderstats" |
4 | local coins = Instance.new("IntValue", f) |
5 | coins.Name = "Coins" |
6 | coins.Value = 0 |
7 | end) |

The problem with the coins script is very simple. See line 3.
1 | if hit.Parent:FindFirstChild("Humanoid") == nil then |
That line checks if FindFirstChild returned nil. The coins could be touching another part, and because of that it fired Touched, and the part's Parent had no Humanoid inside of it. All you need to do is switch the == nil to ~= nil. However that can get messy, so simply don't have it at all:
1 | if hit.Parent:FindFirstChild("Humanoid") then |
2 |
3 | --if not hit.Parent:FindFirstChild("Humanoid") then |
4 | -- If you want to check if it DIDN'T exist, add a 'not' |
Final product:
01 | -- I'm not checking for the humanoid anymore, as you're already checking for the player. |
02 |
03 | local db = true |
04 |
05 | script.Parent.Touched:Connect(function(hit) |
06 |
07 | local player = game.Players:GetPlayerFromCharacter(hit.Parent) |
08 |
09 | if db and player then -- Player may not exist! |
10 | db = false |
11 | script.Parent.Transparency = 1 |
12 |
13 | player.leaderstats.Coins.Value = player.leaderstats.Coins.Value + 1 |
14 | script.Sound.Play() |
15 | wait(60) |
16 | script.Parent.Transparency = 0 |
17 | db = true |
18 | end |
19 | end) |

You set the if statement to check if the humanoid IS nil. Do this.
1 | if hit.Parent:FindFirstChild("Humanoid") ~= nil then |
2 | -- code |
3 | end |
