Why next code runs in same time with for loop and not after it

[PhantomGame_Youtube (Ze_InSoRiTy)]

Topic explains everything. For some reason next code after loop run in same time with for loop

code:

tween.Completed:Connect(function()
			building.Effects.Smoke.Enabled = false
			cc.CFrame = bc2.CFrame
			for _,beamRacks in pairs(building.Union.Photons:GetChildren()) do
				for _,beamRack in pairs(beamRacks:GetDescendants()) do
				if beamRack:IsA("Beam") then
					local thread = coroutine.create(function(object, time, action)
						transparent(object, time, action)
					end)
					
					coroutine.resume(thread, beamRack, 2, "decrease")
				end
				end
			end
			transparent(building.Union.BeamConnectMain.Beam, 2, "decrease")
		end)

Because the loops in are wrapped in a coroutine which doesn’t yield.

Well i can’t do this without coroutine then what i should do

You could just add a task.wait(2)

@PhantomGame_Youtube

transparent(building.Union.BeamConnectMain.Beam, 2, "decrease")

before this
