Attempt to call a Instance value - lua

Question

This error keeps popping up in output, and I'm not sure what I am doing wrong.
Here's the code:
function bullet() --function giving me errors
bullet = Instance.new("Part") --instance
bullet.Size = Vector3.new(1,1,1)
bullet.Position = script.Parent.Position
bullet.Parent = workspace
bullet.Velocity = script.Parent.CFrame.LookVector * 90
bullet.CanCollide = false
--dont think making the script disable then enable after a certain time will work
end
script.Parent.Parent.Activated:Connect(function() --the script is in the handle of the tool
bullet() -- where the error is
--weird thing is, i have made functions like "explode()" that worked just like this and did not have any errors
--pretty sure this is a roblox problem, but i am not sure
--someone help
end)
the error: "Workspace.Tool.Handle.Script:12: attempt to call a Instance value"

Answer 1

--pretty sure this is a roblox problem, but i am not sure
Not the cause is your code.
You define a global function named bullet
function bullet()
-- more code
end
The first thing you do in that function is
bullet = Instance.new("Part")
Doing that you assign the return value of Instance.new("Part") to bullet.
Let's call function bullet the first time bullet()
Now the function is executed and bullet becomes an Instance. It is not a function anymore.
If we now call bullet a second time we get the error
"Workspace.Tool.Handle.Script:12: attempt to call a Instance value"
So bullet basically overwrites itself so it can not be called a second time.
Just use different names to avoid this. Then you should think about the scope. If you want to create a new bullet every time you call bullet you need to make the Intance value local as you would otherwise overwrite the same global bullet every time you call the function.
Try something like
function SpawnBullet() --function giving me errors
local bullet = Instance.new("Part") --instance
bullet.Size = Vector3.new(1,1,1)
bullet.Position = script.Parent.Position
bullet.Parent = workspace
bullet.Velocity = script.Parent.CFrame.LookVector * 90
bullet.CanCollide = false
return bullet
end
script.Parent.Parent.Activated:Connect(function()
SpawnBullet()
end)

Answer 2

Try naming the bullet variable inside the bullet function something besides bullet or change the name of the function

Answer 3

Did you try changing the name of the function or the variable? Maybe that's the problem.
Try:
function CreateBullet() --function giving me errors
bullet = Instance.new("Part") --instance
bullet.Size = Vector3.new(1,1,1)
bullet.Position = script.Parent.Position
bullet.Parent = workspace
bullet.Velocity = script.Parent.CFrame.LookVector * 90
bullet.CanCollide = false
end
script.Parent.Parent.Activated:Connect(function()
CreateBullet()
end)
I'm sorry if it didn't work or if I wasn't helpful.
