Loop *technically* only runs once

basically, i have a loop that moves a certain part to a certain enemy. pretty simple. now theres a bit of a glitch with this: the first while loop works fine… but the next one just ignores everything and doesnt run the “moving the part” code. here’s the script:

while slashstormmainpart ~= nil do
	print("starting loop")
	local smallestdistance = 70
	local targetpart
	
	for i, v in pairs(workspace.zombiesworkspace:GetChildren()) do
		task.wait()
		if v:FindFirstChild("HumanoidRootPart") ~= nil and v:FindFirstChildOfClass("Humanoid") ~= nil and game.Players:GetPlayerFromCharacter(v) == nil then
			print("maybe found")
			if (v.HumanoidRootPart.Position - slashstormmainpart.Position).Magnitude < smallestdistance and v:FindFirstChildOfClass("Humanoid").Health > 0 then
				print("whoa found")
				smallestdistance = (v.HumanoidRootPart.Position - slashstormmainpart.Position).Magnitude
				targetpart = v.HumanoidRootPart
			end
		end
	end
						
	if targetpart ~= nil then
		local timetomove = smallestdistance/4
		print(timetomove)
		for i = 0.01, timetomove, .01 do
			print(i/timetomove)
			slashstormmainpart.Position = slashstormmainpart.Position:Lerp(targetpart.Position, i/timetomove + 0.05)
			slashstormmainpart.CFrame = CFrame.lookAt(slashstormmainpart.Position, targetpart.Position) * CFrame.Angles(math.pi, 0, 0)
			task.wait(.01)
		end
	else
		print("no targetpart")
	end
	print("ending loop")
	task.wait(.4)
end

the first time it runs it fully prints the “i/timetomove” thingy buut the next time it just spams
“starting loop” “maybe found” “no targetpart” “ending loop”

Instead of printing some words after an if check, print the variables checked inside the if before it for better troubleshooting. It lets you know why an if is doing something unexpected.
Something like:

print("x = ", x, "   y = ", y) -- tells you what's going on with the variables
if x < y then 
print("it worked")   -- doesn't tell you why it's NOT working
-- code
end

Then you know where to look at the variables to see why they aren't working.

ahh alright ill do that when im able to.

oh, it seems that… for some reason after it finishes the for i = 0.01 loop it just goes to the coordinates 0, -3, 0. welp i think ill be able to fix that. probably. maybe.

oh wait its not 0, -3, 0. its actually 0, -340282346638528859811704183484516925440, 0. very weird pls help

i think i found the issue, the positions given to cframe.lookat are the same, which causes it to go ASTRONOMICALLY far away. i can just switch the places of these lines and it should work alright. slashstormmainpart.Position = slashstormmainpart.Position:Lerp(targetpart.Position, i/timetomove + 0.05) slashstormmainpart.CFrame = CFrame.lookAt(slashstormmainpart.Position, targetpart.Position) * CFrame.Angles(math.pi, 0, 0)

fixed it by doing this:

for i = 0.01, timetomove, .01 do
								print(i/timetomove)
								if slashstormmainpart.Position == targetpart.Position then
									slashstormmainpart.Position = slashstormmainpart.Position + Vector3.new(0, 1, 0)
								end
								slashstormmainpart.CFrame = CFrame.lookAt(slashstormmainpart.Position, targetpart.Position) * CFrame.Angles(math.pi, 0, 0)
								slashstormmainpart.Position = slashstormmainpart.Position:Lerp(targetpart.Position, i/timetomove + 0.05)
								if i == timetomove then
									slashstormmainpart.Position = targetpart.Position
								end
								task.wait(.01)
							end
