how to make a debounce on this

[burnt smelt]

i got a similar script but it's on the baseplate but idk how to apply it

you need to add a then statement after your condition

local KillBrick = script.Parent
local IsTouched = false

KillBrick.Touched:Connect(function(HitPart)
    local Humanoid = HitPart.Parent:FindFirstChild("Humanoid")

if Humanoid then
      Humanoid.Health -= 25
  end
end)

second, your checking if an instance is false, which is not the correct way to check if something exists. you need to see if it exists by checking if it's not nil, which there are two methods for:

if example ~= nil then
-- code here
end

and the better way:
if example then
-- code here
end
