"Attempt to index nil with 'CFrame'" error despite script working fine before

Help and Feedback Scripting Support
#1

I am trying to eject a casing on the server side whenever a gun is fired from the player. The entire script is working fine, but I decided to make the casing a model with a cylinder so it can roll and a sphere on one end so it doesn’t always stand up.

However, suddenly my script just decided to not work and error on me?

-- Assume the casing variable is declared before
local CasingPrim = Casing.PrimaryPart -- declare primary part variable
Casing.Parent = workspace.Debris
--[[Error here]] CasingPrim.CFrame = player.Character:FindFirstChild("CaseExit", true).CFrame * CFrame.Angles(0, math.rad(90), 0)
local offsetcframe = CasingPrim.CFrame + CasingPrim.CFrame.LookVector * offset
CasingPrim:ApplyImpulse(offsetcframe.Position * CasingPrim.AssemblyMass)
Debris:AddItem(Casing, 10)

Looks like CasingPrim gets destroyed, try printing it. If it prints nil, then its getting destroyed somehow. Where is this part stored?

#3

It is a part of the model which is a mesh.

#4

Is there a script that calls :Destroy() on members of workspace.Debris?

#5

Are you referring to Debris:AddItem(Casing, 10)?

#6

no, because that is called after the error. it will not run. i mean any other script in your game that could be deleting things.

#7

Nothing else is deleted in the game

#8

This is a pretty obvious fault. Casing has no primary part. Figure out why

#9

I did set its primary part, still the same error.

#10

Observe the primary-part at runtime. You will see that it is not there. Make this observation on the same end of the network that the above code is running on

#11

They all have a primary part when running?

#12

Ah. Don’t mind me then. I scrolled further right and noticed you have a second instance of indexing a CFrame:

player.Character:FindFirstChild("CaseExit", true)

This is likely the cuplrit; no descendant of the character named “CaseExit” could be found

#13

That is part of the gun where the case should be spawning from, and it worked fine previously and because of that I’m not sure how to fix it.
