Spawn & set timer with Device and verse basic knowledge.

I have some question on how exactly “think” and “use” verse.
Let me explain.

I placed a timer in the level, and made an editable variable of the Timer-type.
So i can select it correctly and now is stored in the variable (like in the tutorial)

Timers have a var for the “Time” can i set it via verse? how do i know?
Reading in the Timed_objective_device_class’s page i dont see variables, neither functions to set the variables.
I cant do it ?

Writing code using autocompletion, i often get the Full list of everything instead of what is available inside that class, why?

This lead me to a lot of question,
i m using the variable to set the timer,
but can i spawn new stuff via verse?
Can i do Linetracing ?

There is a Parent class to store any object?
Can we still “Cast_to” stuff? or at least check te type inside?

Pretty lost here
