Tank you for your answer,but i don鈥檛 know how i can access tick number and use it in my script!.how i can convert this code to dotnet code?.
——start code
rollout test 鈥淭est Timer鈥?br>
(
timer clock 鈥渢estClock鈥?interval:1000 –tick once a second
label testLabel 鈥?鈥?br>
on clock tick do
(
testLabel.text = (clock.ticks as string)
)
)
createDialog test
—–end code
鈥搈y goal is clock.ticks

The argument passed to the 鈥榚lapsed鈥?event handler includes the 鈥楽ignalTime鈥? You can use that to determine precisely how much time has gone by.

鈥ut it sounds like you might just need to increment a counter?

rollout test "Test Timer"
(
	label signalTime ""
	label elapsedTime ""

	local startTime
	local myTimer = dotnetobject "System.Timers.Timer" 1000 autoreset:true
 	
	fn onElapsed sender args =
	(
		signalTime.text = args.SignalTime.ToString()
		elapsedTime.text = (args.SignalTime.Subtract(startTime)).ToString()
	)

	on test open do
	(
		dotnet.AddEventHandler myTimer #elapsed onElapsed
		startTime = (dotnetclass "datetime").now
		myTimer.Start()
	)

)
try (destroyDialog test) catch()
createDialog test

Tank you for your answer.actually yea,counter is a good and simple way.and maybe best way!
I鈥檓 going to make UI for loading archive animations on character.first i made a listbox,but it was not enough good.next idea was using windows-media in UI for showing animations preview,but it has many bugs such as video size don鈥檛 work with script!and many other bugs.next idea was making a button for showing image sequences.but max dialog has a bug in update that cause jump in frames and bad showing images.finally i decide to use dotnet form instead of max UI,it was perfect!my code is not complete but take a look at.
