While conditional loop causing lag?

Help and Feedback Scripting Support
#1

I was using a while loop to delay a part of a script

while tick() - lastick < 30.5 do
if not char:IsDescendantOf(game) then
       break
end
if tick() - lastick >= 30 then
      -- what the script will do when conditional is done, I have this because if i put the rest of the script under this while loop and the other conditional breaks the loop it will error
      break
end
RService.Heartbeat:Wait()
end

lastick gets updated so that it resets my timer if needed be, however this is lagging my game. I’ve reached this conclusion because I’ve checked script performance, but I don’t know why it lags my game. I think it may be that its constantly calculating tick - lastick which causes lag, but this shouldn’t be performance heavy right?

Why not remove the while condition check if you’re already checking for it inside the loop itself?

#3

Tried that didn’t change anything

Is this being run cross server or locally? Also while loops for me have always sucked no matter the condition and I try to avoid them. If I am correct (kind of a beginner scripter heh) you might want to consider using a loop under RunService not sure if this applies though.

If you mean, A to run a while loop under a heartbeat event, then that would lead to a memory leak cause you would start a new while loop per frame. B, if you mean to use the conditional under heartbeat and disconnect it later, then that would be the same thing basically, no?

#6

Not really knowledgeable on memory leaks so I cant say for sure, now for your second part I think I was talking about RunService.RenderStepped though I think that would effect the actual timer on the local side for users?

#7

Its being ran on server per player

#8

Have you tried putting print(“n”,tick()) where n is a number to indicate the print location in the code and tick gives you the time it reached that print.
Might help finding where the lag is.

I already found the source of lag and fixed it, thanks for the help though

#10

Would you care to share what you found so others may know how to resolve similar problems?

#11

It was the rate I was checking the if statement, I was running the loop 60 times a second and that wasn’t needed because I’m checking if I delayed the script for 30 seconds. Replacing the heartbeat with a wait(1) fixed it.
