Problems with tables

Help and Feedback Scripting Support
#1

Achievement:
Have a script change a value in ReplicatedStorage whenever a Enemy is added into a folder (using tables).

Issue:
Everytime an enemy dies, it shows this as the error
“Workspace.Scripts.Script:15: invalid argument #2 to ‘remove’ (number expected, got Instance)”.

Attempted Solutions:
Trying to change the amount of time till the Enemy gets destroyed inside of a different script, just changed the Error time

Code:

--// Variables
local Folder = workspace.Enemies
local EnemyTable = {}
local EnemyAmount = game:GetService("ReplicatedStorage").GamePlayFiles.EnemyAmount

--// Adding Enemy
Folder.ChildAdded:Connect(function(enemy)
	table.insert(EnemyTable, enemy)
	EnemyAmount.Value = #EnemyTable
end)

--// Removing Enemy
Folder.ChildRemoved:Connect(function(enemy)
	table.remove(EnemyTable, enemy)
	EnemyAmount.Value = #EnemyTable
end)

Thanks to anyone who helped!

enemy is not even a number, you have to put the index of the enemy in the table.remove line

#3

Here we get the index of the enemy, then remove it with the index we found.

local enemyIndex = table.find(EnemyTable,enemy)
if enemyIndex then
	table.remove(EnemyTable,enemyIndex)
end
#4

table.remove(Table, table.find(Table, Value))

#5

The only issue why I did it that way, is because it could result in an error if the enemy doesn’t exist in the table, that’s why I checked if the index was nil before removing.

table.remove(Table, nil) doesn’t error.

local Value = table.remove(Table, table.find(Table, Value))
if Value then --Validate that a table entry was removed.
