I think I know the answer already, but just in case anyone has any ideas or I'm missing something...
Is it not possible to include a user variable as part of the input string on a UDP event? To be clear, I'm not trying to manipulate the variable, but use it as part of the "listening" value. For example, using the player's IP address (defined as a system variable and addressed as $$myIP$$) as an identifier.
So with the above, a UDP event defined as $$myIP$$=displayPowerOn
Doesn't seem to work.
The idea here was to be able to send out commands on the broadcast address that reference all players, groups of players, or only a single player by encoding just 3 strings in a user event, and not having to manipulate every single project to enter unique values on UDP inputs.
