| I use this 
 deletatimer.monkey
 
 
 
Strict
Import mojo.app
Class DeltaTimer
	Field fps:Float = 60
	Field currentticks:Float
	Field lastticks:Float
	Field frametime:Float
	Field delta:Float
	
	Method New(inpfps:Float)
		fps = inpfps
		lastticks = Millisecs()
	End
	
	Method UpdateDelta:Void()
		currentticks = Millisecs()
		frametime = currentticks - lastticks
		delta = frametime / (1000.0 / fps )
		lastticks = currentticks
	End
End
 
 
 then make it a global so all classes /methods can reach it
 
 
Import deltatimer ' import the file
Global dt:DeltaTimer ' next line make it global
 
 in the game class do this
 
 
Method OnCreate:Int()
 		dt = New DeltaTimer(30) ' or something else
		SetUpdateRate dt.fps
		
		' do things
		Return 0
	End
	
	Method OnUpdate:Int()
		dt.UpdateDelta()
		' do things
		Return 0
	End
 
 
 then you can use it in all classes like this
 
 
y=y+10 * dt.delta
