Function Documentation

down()

void down

(

int

n

)

Moves the pen's position "down" (increases the y coordinate).

Example: down(10) will move the pen's position down 10 spots (y will change by 10).

Parameters

n	The number of steps to move down.

end()

void end

(

)

Indicates the end of your drawing.

go()

void go	(	int	x,
		int	y
	)

Moves the pen's position to the given coordinate.

Example: go(10, 5) will cause the pen's position to change to (10,5).

Parameters

x	The x coordinate to move to.
y	The y coordinate to move to.

left()

void left

(

int

n

)

Moves the pen's position "left" (decreases the x coordinate).

Example: left(10) will move the pen's position to the left 10 spots (x will change by -10).

Parameters

n	The number of steps to move left.

pendown()

void pendown

(

)

Sets the pen down so that using go() or the other movement functions will cause a line to be drawn until penup() is called.

penup()

void penup

(

)

Lifts the pen so the go() and the other functions may be invoked without causing a line to be drawn.

right()

void right

(

int

n

)

Moves the pen's position "right" (increases the x coordinate).

Example: right(10) will move the pen's position to the right 10 spots (x will change by 10).

Parameters

n	The number of steps to move right.

start()

void start

(

)

Indicates the start of your drawing.

up()

void up

(

int

n

)

Moves the pen's position "up" (decreases the y coordinate).

Example: up(10) will move the pen's position up 10 spots (y will change by -10).

Parameters

n	The number of steps to move up.
