Workspace.Lucky_Blocks.Lucky_Block1.Script: attempt to index nil with backpack?

Asked by

Hello, I was making something for my game, But an error happened, Could anyone fix this?

What I was trying to do is Clone the Tools to the Player's backpack, But this error happened:

"Workspace.Lucky_Blocks.Lucky_Block1.Script: attempt to index nil with backpack"

I don't know how to fix the script.

Script:

local player = game.Players.LocalPlayer
local backpack = player.Backpack
local GearsFolder = game.ReplicatedStorage.Gears

script.Parent.Touched:Connect(function(hit)
    local lucky = math.random(1,6)
    if lucky == 1 then
        GearsFolder.Bloxy_Cola:Clone().Parent = backpack
    elseif lucky == 2 then
        GearsFolder.Lightbox_Jar:Clone().Parent = backpack
    elseif lucky == 3 then
        GearsFolder.Panda_Friend:Clone().Parent = backpack
    elseif lucky == 4 then
        GearsFolder.Red_Rolling_Hoverboard:Clone().Parent = backpack
    elseif lucky == 5 then
        GearsFolder.Taco:Clone().Parent = backpack
    elseif lucky == 6 then
        GearsFolder.Toms_Beans:Clone().Parent = backpack
    elseif lucky > 6 then
        warn("Warning: Your unlucky.")
    end
end)

You cannot get the LocalPlayer on the Server. You can only do this in a LocalScript. but you can use the touched event parameter to get the player MarkedTomato 810 — 3y

In the touched event function do this local player = game.Players:GetPlayerFromCharacter(hit.Parent) add some sanity checks to make sure it's the character before adding the player code in MarkedTomato 810 — 3y

When answering, if your answer does not fully solve the question, it should be written as a comment to the question instead of as an answer.

Hi The problem here is that you are using a script (which is server based) to find a local player, therefore you cannot find the backpack, hence the error. So maybe try changing the script into a local script and see if you get any errors! -- PS YOU WILL NEED A REMOTE EVENT AS LOCAL SCRIPTS CANNOT DETECT TOUCHED EVENTS

Hope this helped!

Any questions? Just ask!

He can use game.Players:GetPlayerFromCharacter(hit.Parent) MarkedTomato 810 — 3y

with a sanity check that checks if hit is actually a character that has a humanoid MarkedTomato 810 — 3y

local GearsFolder = game.ReplicatedStorage.Gears

script.Parent.Touched:Connect(function(hit)
   local humanoid = hit.Parent:FindFirstChild("Humanoid")
   local backpack = nil
   if humanoid then
      if game.Players:FindFirstChild(char.Name) then
         local player = game.Players:GetPlayerFromCharacter(humanoid.Parent)
         local backpack = player.Backpack
      end
   end

    local lucky = math.random(1,6)
    if lucky == 1 then
        GearsFolder.Bloxy_Cola:Clone().Parent = backpack
    elseif lucky == 2 then
        GearsFolder.Lightbox_Jar:Clone().Parent = backpack
    elseif lucky == 3 then
        GearsFolder.Panda_Friend:Clone().Parent = backpack
    elseif lucky == 4 then
        GearsFolder.Red_Rolling_Hoverboard:Clone().Parent = backpack
    elseif lucky == 5 then
        GearsFolder.Taco:Clone().Parent = backpack
    elseif lucky == 6 then
        GearsFolder.Toms_Beans:Clone().Parent = backpack
    elseif lucky > 6 then
        warn("Warning: Your unlucky.")
    end
end)

----------EXPLANATION----------

So, I'm just gonna explain the code that I just added in.

First, there's a variable that checks if hit.Parent has a humanoid. hit.Parent is the character model.

The backpack variable is equal to nil, nil means nothingness.

After that, It checks if the character has a humanoid then, it'll run the code in that scope which is just another sanity check.

Before we go further, you'd be questioning, how is it true? "FindFirstChild just returns an instance" well if it returns something, it's true otherwise, false, or nil.

Next, it'll look through the PlayerService and see if the character name is a child of the PlayerService, I did this just in case if it's an NPC.

After that, it gets the player and the player's backpack.
