Setting custom state transition time from code

Question

Is it any possibility to set a transition time for certain state directly from game code?  

For example, we want to perform a state transition during the level loading (duration which varies from time to time).

Answer 1

Unfortunately, no, you can't.

The only way to specify a transition time in the game code is by using the API function ExecuteActionOnEvent.  With this function, you can Stop, Pause, Resume and Break on existing event actions.
