RLOP1'S PROFILE

RPG Maker VX Ace
I'm a total newbie in script making, so this might not make much sense.
But basically I'm trying to make a script that will allow a boat to go on tiles with the region id 1. So far this is what I have:

def movable?
!moving? && ! (@type == :boat && @gameMap.region_Id === 1)
end

It wasn't working, so I decided to come here for help. Like I said, I'm a newbie. This is literally my first script. So it probably makes no sense. But if anyone can help me make one that works that'd be great.
