What exactly is the problem?
So once the data is sent like so on the Photon raise event action, on the TRIGGER, if you want to access Sprite.X, you use say, a local variable Token0 and assigned it to int(tokenat(Photon.EventData,0,"|")).
As an example if Sprite.X = 50 and Sprite.Y = 75, Photon sends as a string 50|75|
tokenat(Photon.EventData,0,"|") gets the 1st element from that string until the delimiter, which is |, so 50, then using int(50) you transform it from string to int.
