How to correctly use tables with "If"?
So, i have a table with some string values:
1 | table = {"Part","Brick","Something"} |
And i have script which destroys anything it touches:
1 | function destroy(WhoTouched) |
2 | WhoTouched:Destroy() |
3 | end |
4 | script.Parent.Touched:connect(destroy) |
But i need to check the name of the brick, and if name in the table, do not destroy that part:
1 | for index,value in pairs(table) do |
2 | if WhoTouched.Name ~= value then |
3 | WhoTouched:Destroy() |
4 | end |
5 | end |
The problem is - if table contains more than one value, script destroys everything, even parts with names in the table. So how exactly do i check name?

Instead of using a for loop use a trick some people use, a "map-style" table or a Dictionary.
Dictionary
It's an array where you can actually SET the index in the table.
1 | table = { |
2 | ["ROBLOX"] = "Multiplayer game", |
3 | ["LordDragonZord"] = "Amazing", |
4 | ["Scripting"] = "Cool" |
5 | } |
6 |
7 | print(table["ROBLOX"]) --Will print "Multiplayer game" |
Final Product
01 | safe = { |
02 | ["Part"] = true, |
03 | ["Brick"] = true, |
04 | ["Something"] = true |
05 | }--You can fit this on one line, I just did this so it's easier to read. |
06 |
07 | script.Parent.Touched:connect(function(p) |
08 | if not safe[p.Name] then |
09 | p:Destroy() |
10 | end |
11 | end) |
Hope it helps!
