What is the value of 'simulation frame' in Export.lua?

[JedimasterLu]

I'm trying to export data through Export.lua file. I read the example but couldn't find a function returning the velocity of all the units. Therefore, I wonder if I can manually calculate the velocity base on the difference between the position in each frame. In order to calculate the velocity, I have got to know the time between each simulation frames.

Is it a constant value like 60? Or is it the actual FPS of the game?

And are there other ways to get velocity of an object by its ID in Export.lua?

Thanks for all the help!

My experience with export is limited, but IIRC there is no "schedule function" to make sure something runs in X seconds from now or anything like that. But what you can do is use onSimulationFrame to check the time between it was last run and you can then execute functionality every x seconds rather than every single frame. 

It might aim for 60, but its best to sample the time each time it is run and check the difference.

Thanks! I find a function called,

LoGetModelTime() -- returns current model time (args - 0, results - 1 (sec))

and it do return the actual time!

On your client side instance it will depend on your FPS, on a dedicated server its a fixed time, 0.0154 the last time i checked.
