I am playing an Age of Rebellion campaign with my friends and a problem occurred in an encounter with some stormtroppers on board a stardestroyer. We are fairly new to the game and used to playing DnD. The Stormtroopers were inside a room, and our group was outside and the door was already open. To start the encounter a PC moved and stood in the door opening, then started shooting at the troopers. After this we rolled initiative. Problem is that this PC could move first in the encounter, use his action to shoot and move out of the way to be hidden from line of sight. Is this possible? Also could all of the PC's have a "Surprise" turn to stand in the door and shoot?
Another thing, are you able to move into the doorway, shoot and move out again all in one turn? It seems wrong.
I am not sure but it seems like it doesn't cost a maneuver to move within short range. So can you move anywhere within short as an incidental?
