Hi.
not at all, where did you read that? it's as precise.
to check a down time, record the time when the user pressed down, and when the user press up record the time, then make a substraction and you have the duration of the press, precise as it can be...
use "RealTimeSinceStartup", which means it's not going to be affected by te time scale. use "TimeSinceStartup" if you want to toy around with slowing down time inside the game and account for this in your timer.
Bye,
Jean
