How can I make the for loop "for i,v in pairs(char:GetChildren())" do only happen once?

Backstory So for loops can be used for many things either that being getting the children of a object or making and event happening a certain amount of times. For me I'm using a for loop to get the children in a object that i will turn its transparency to 1. This script will then will be sent to the server using FE.

Problem So my actual problem is this. How can i make the for loops for i,v in pairs(char:GetChildren()) do only happen once. This script is playing mutiple times and then stopping when the player has for looped v enough times. Thank you!

Local Script

game.Workspace.Spart.ClickDetector.MouseClick:Connect(function()
    UIS.InputBegan:Connect(function(Input,gp)
        if Input.KeyCode == Enum.KeyCode.E and not gp then
            if not en then return end
            en = false
                                    for i,v in pairs(char:GetChildren()) do
                if i:IsA("Accessory") then
                    local BackupAc = v:Clone()
            game.ReplicatedStorage.SRemote3:FireServer(hum,root,Mouse.hit,SCircle,char,BackupAc)
            wait(0.1)
            char["Left Arm"].Transparency = 0
            char["Right Arm"].Transparency = 0

                end
            end
end)

Try not to pay attention to the actual script but the problem because the script is quite long.
