I have pretty basic, fundamental question here, but it caused some heated debate at the last game night, so I wanted to ask the community. The scenario is this:
I have an Academy TIE Fighter. I perform a maneuver, and declare my action as a barrel roll left. I place my R1 template on the front left of the ship base, and move the ship to the other side of the template as far back on the ship base as possible. Placing the ship here causes the front corner to overlap debris, so I am not able to complete the action. However, if I was to shift the TIE slightly backwards, it would not be in contact with the debris, and could thus be legally completed.
My question is this: Do I have to try all possible positions in order to legally complete the barrel roll, or can I declare myself unable to complete it if my initial positioning is does not allow it to complete?
Follow up question: Am I allowed to move the ship forward or backward on the template while deciding where I want it to be, or does it have to be kept where I initially placed it?
Thanks!
