I want to change this script up but how?

What you need to do is add Debounce. Debounce prevents a piece of code from running too many times.

local Brick = game.Workspace.TeleBrick --Replace this with your brick 

local debounce = false

Brick.Touched:connect(function(Obj) --Connects the Touched event to an anonymous function 
   if debounce == true then return end -- Prevents the code from executing multiple times.
  debounce = true -- Makes the above line work.
   Brick.Transparency = 1 
    Brick.CFrame = CFrame.new( --Replace the Min and Max in the math.random() with your numbers 
                        math.random(-62.5, 62.5 ), 
                        math.random(3.19, 3.19), 
                        math.random(-62.5, 62.5)
                    ) 
Brick.Transparency = 0
    if Obj and Obj.Parent then --Making sure the Obj still exists 
        local Player = game.Players:GetPlayerFromCharacter(Obj.Parent) --Gets the player from the character 
        if Player then 
            local PointStat = Player.leaderstats:FindFirstChild("Points") --Replace STAT_NAME with the name of the stat 
            if PointStat then 
                PointStat.Value = PointStat.Value + 2 --Change 1 to how many points you want to award 
            end 
        end 
    end 
    wait(1) -- Waits a second before the code below executes.
    debounce = false -- Makes the code work once again.
end) 

If I helped please put me as the answer and vote me up. Thank you for reading!
