How to Create a Line

• Define the begin point (1) and the end point(2)

• Begin Point: x1, y1• End Point: x2, y2• The Command to Draw the Line :– Line x1, y1, x2, y2– Example: Line 40, 50, 100, 200

How to Create Shapes:

• A Rectangle: define the point in the upper-left corner(1) and the point in the lower-right corner(2).– Rectangle x1, y1, x2, y2– Example: Rectangle 40, 50, 100, 200

• A Circle: define it like a rectangle. The circle is drawn inside that rectangle.– Circle x1, y1, x2, y2– Example: Circle 40, 50, 100, 200

//To draw a line, define the begin point and end point.//Line x-coordinate of begin point, y-coordinate of begin point,// x-coordinate of end point, y-coordinate of end point

Line 0,400,800,400

//Rectangle, x-coordinate of upper-left corner, y-coordinate of upper-left corner,// x-coordinate of lower-right corner, y-coordinate of lower-right corner Rectangle 100,100,200,300

//Circle is created the same way as a rectangle with coordinates for a rectangle,//BUT drawn INSIDE the rectangle.

Circle 300,100,500,300

Robot Basic Commands & their Meaning

• rLocate x,y

• rTurn angle

• rForward pixels

• End

• Places the robot simulator on the screen at the x, y coordinates.

• Turns the robot at the angle specified (it defaults to pointing up).

• Moves the robot forward the number of pixels.

• Ends the program.

ALL ROBOT COMMANDS BEGIN WITH AN ‘R’

•Places robot at coordinates 100 for x, and 200 for y.•Robot turns 90 degrees (right).•Robot moves forward 500 pixels.•Robot turns 180 degrees (halfway arount).•Robot moves forward 500 pixels.•Program ends.
