Table.find not working correctly

[crisgamer3YT (Taitansito)]

I am making a construction system that is activated by pressing the F key, when the construction mode is deactivated all the selected objects should be deselected, but that does not happen, only some are deactivated, so I was searching in my code the error is in the table.find, since for some reason it does not return the value it should and does not work, I have been racking my brain for 5 hours looking for a solution.

function unSetSelection(obj)

   if table.find(selections, obj.Parent) then
      table.remove(selections, table.find(selections, obj.Parent))
      obj.Selections:Destroy()
      
   else
      warn("Objeto no esta enlistado")
   end
   
end

If you see any errors, please let me know and thanks in advance.

Can you provide the full code with the selections table etc.?

[loudbytes]

is the selections table an array?

[crisgamer3YT (Taitansito)]

sure

local selections = {}

function setSelection(obj) -- inserts the parent of the object into the table, which in all cases is a Model
   local mark = Instance.new("SelectionBox", obj)

   mark.Name = "Selections"
   mark.Color3 = colorSelection[obj.Parent:GetAttribute("type")]
   --mark.SurfaceColor3 = Color3.new(1, 1, 1)
   mark.LineThickness = 0.025
   mark.SurfaceTransparency = 0.75
   mark.Adornee = obj

   local t = TWEEN:Create(mark, TweenInfo.new(1, Enum.EasingStyle.Linear, Enum.EasingDirection.InOut, -1, true), {["SurfaceTransparency"] = 0.6})
   t:Play()

   table.insert(selections, obj.Parent)
end

function unSetSelection(obj) -- removes the selected instance from the table

   if table.find(selections, obj.Parent) then
      table.remove(selections, table.find(selections, obj.Parent))
      obj.Selections:Destroy()
      
   else
      warn("Object is not listed")
   end
   
end

UIS.InputBegan:Connect(function(key, GameProcessed)
   if GameProcessed then return end
   
   if key.KeyCode == Enum.KeyCode.F then

      configPlayer:SetAttribute("editorMode", not configPlayer:GetAttribute("editorMode"))

      showSelection(nil)

      for _, o in selections do
         unSetSelection(o.selectionPart)
      end

      warn("Editor Mode:", configPlayer:GetAttribute("editorMode"))

   end
end)

As seen in the script, pressing F should deactivate all selections but instead of doing that the following happens:

@crisgamer3YT

for _, o in selections do
         unSetSelection(o.selectionPart)
      end

When using table.remove() it shifts all the other elements in the array to fill the gap. Which is why in the video it removes the first ok, and then the third (which is now the second element).

You could loop the table backwards, or recursively call unset while the table length is greater than 1.

for i = #selections, 1, -1 do
    unsetSelection(selections[i].selectionPart)
end

--or

while #selections > 1 do
    unsetSelection(selections[#selections].selectionPart)
end

@Wigglyaa

for i = #selections, 1, -1 do
    unsetSelection(selections[i].selectionPart)
end

Thank you very much for your help, I will take it into consideration in my future projects
