Navigation based from variables

Hello, 

I want to make an interactive presentation which uses variables as a method of choosing which 'route' / next state to take, rather than using the existing keyboard / remote / UDP etc inputs. 

 

Background: I have 2 video files - 50fps and 59.94fps. an Interactive menu shows 2 menu items - one for each file. when the user selects the 50fps version, it instigates a video mode change to 1920x1080 50p , which in turn reboots the XT1143 player. (and vice versa for the 59.94 file). Currently, after the player has rebooted into the new frame rate, it starts as normal at the menu screen, but I would like it to jump directly to the correct file. So I can set variables, which 'stick' through the reboot, its just I have not worked out a way of performing logic on these, once the reboot has completed, to play the file directly. 

 

Is this possible?

 

Thank you

  So I wonder if you could set Conditional Targets on the first iten in your Presentation?  And those would examin the variable such that if it is equal to X then do this thing and if equal to Y then do another thing.

  Hi Allen, - yeah thats what I thought would do the trick, but I have not yet got round the limitations of brightauthor.. e.g. Conditional Targets dont appear on media items, only on 'event' items like keyboard , IR etc events.. you can do them on media end events, but this didnt work for me.

  I have only ever put them on media ends and timers.  You could throw down an Event Handler as the initial state and attach a .2 second timer and put the Conditional Targets in there...

   

   

  Or put a see-thru PNG file as the initial state and attach the timer there.

  Sorry, I said "timer" and I meant variable.  I am used to using countdown variables to act as "timers" to do stuff.

  Hi - this is now solved with: 

  an initial state of 1 seconds of silent .WAV. Media End event connects this to an arbitrary Event Handler. The Media End event has the conditional targets configured, to transition to the video files based on the variable. All good! thank you.
