Plr is a nil value?!
I'm trying to script a door which requires a key to open it. Here is the script:
01 | script.Parent.Touched:connect(function(hit) |
02 | if hit.Parent ~= nil then |
03 | local plr = game.Players:GetPlayerFromCharacter(hit.Parent) |
04 | if plr.Backpack:FindFirstChild('Temple Key') then -- The problem!!! |
05 | script.Parent.Transparency = 0.7 |
06 | script.Parent.CanCollide = false |
07 | plr.Backpack['Temple Key']:Destroy() |
08 | wait(5) |
09 | script.Parent.Transparency = 0 |
10 | script.Parent.CanCollide = true |
11 | end |
12 | end |
13 | end) |
When I touched the door (with and without the key), the output stated this error: 16:56:04.906 - Workspace.Union.Script:4: attempt to index local 'plr' (a nil value)
How am I able to fix line 4 of the script above?

You're assuming that some brick didn't just hit the part. Line 2 would tell the script to proceed, however line 3 will return nil if the brick's parent isn't a character model. Therefore line 4 will give the mentioned error. M39a9am3R 3210 — 8y

Please provide explanation with your answers. Simply posting code does not spread knowledge of integral scripting processes which helps people understand the logic and reasoning behind your answer.
01 | script.Parent.Touched:connect(function(hit) |
02 | local human = hit.Parent:findFirstChild("Humanoid") |
03 | if (human ~= nil ) then -- check if it is a player |
04 | local plr = game.Players:GetPlayerFromCharacter(hit.Parent) |
05 | if plr.Backpack:FindFirstChild('Temple Key') then |
06 | script.Parent.Transparency = 0.7 |
07 | script.Parent.CanCollide = false |
08 | plr.Backpack['Temple Key']:Destroy() |
09 | wait(5) |
10 | script.Parent.Transparency = 0 |
11 | script.Parent.CanCollide = true |
12 | end |
13 | end |
14 | end) |
