Note: Text in blue needs to be a constant. Text in red needs to be an argument.
The dock script:
If Link has the sail, then when he steps on the ffc (the dock), a list of unlocked islands popup, and Link warps to a screen where he sails to the one chosen.
Else, when he steps near the ffc, he freezes and a message is played (do only once).
The boat script:
Ok. This is where it gets complicated.
There are 3 ffcs on the screen right now. Link is frozen and invisible.
FFC#1 is the boat and sail.
FFC#2 is "Link".
FFC#3 is the water behind the boat.
When up is pressed, ffcs 1 and 2 move up.
When down is pressed, ffcs 1 and 2 move down.
When left or right is pressed, nothing happens.
If A is pressed, the ffcs 1 and 2 jump.
3 types of obstacles will "move" to the left from a random position off the right side.
If one hits FFC#2, Link loses a heart.
FFC#4 will be used for the barrel/ice.
FFC#5 will be used for the whirlpool.
FFC#6 will be used for the cyclone.
Also, if Link has a cannon, the obstacles will appear less often and zoras will appear and shoot fireballs at FFC#2.
If B is pressed, the cannon fires.
FFC#7 will be used for the cannon ball.
After a few min. Link will warp to Dmap, screen.
I will owe whoever makes me this a big favor.
