Error attempting to index a nil value?
The script is suppose to allow the player to simulate "shooting" and when there cursor goes over a player, they will take damage. the issue is, after a while of "shooting" i get this error attempt to index local 'raw' (a nil value)
Any solutions?
01 | player = game.Players.LocalPlayer |
02 | character = player.Character |
03 | gun = character:FindFirstChild("Rifle") |
04 | mouse = player:GetMouse() |
05 | auto = false |
06 | function getModel(raw) |
07 | for _, child in pairs(workspace:GetChildren()) do |
08 | --calling pairs is barely any slower than using next directly, plus it's easier to read. |
09 | if raw:IsDescendantOf(child) then |
10 | return child; |
11 | end; |
12 | end; |
13 | return nil; --this allows us to not use pcall |
14 | end; |

Your problem is that when mouse.Target is the skybox, it returns nil. The simple fix is checking to make sure it isn't nil before carrying out with the code
Check line 9 to see what I've changed
01 | player = game.Players.LocalPlayer |
02 | character = player.Character |
03 | gun = character:FindFirstChild("Rifle") |
04 | mouse = player:GetMouse() |
05 | auto = false |
06 | function getModel(raw) |
07 | for _, child in pairs(workspace:GetChildren()) do |
08 | --calling pairs is barely any slower than using next directly, plus it's easier to read. |
09 | if raw ~= nil and raw:IsDescendantOf(child) then |
10 | return child; |
11 | end; |
12 | end; |
13 | return nil; --this allows us to not use pcall |
14 | end; |

Well, as seen in your question, you're indexing a nil value. The only thing I can think of making game.Players.LocalPlayer:GetMouse().Target return nil is this script's implementation.
This script should be ran from a LocalScript, since LocalScripts are the only class that can invoke game.Players.LocalPlayer and have it work correctly throughout servers.
Hope this helps! Comment if you need more assistance or a further explanation!
