COMPLEX COMPOUND BEHAVIORS
determined randomly. If two adjacent junctions have lines toward each other then the junctions would be connected. We save the maze characteristics in an array Maze[ ] to be able to use the maze again. The array holds a binary number (4 bits) to indicate which lines are to be plotted. The code also takes consideration of whether it is the rst time the program is being run which means that the maze should be generated. If it is not the rst time the program is run, the maze is plotted from the array Maze[ ]. Think of this maze as a city with north-south and east-west streets. Some streets intersect, some are dead ends, and parts of the city may not be reachable from some starting points. 14.1.1.5 PlaceRobot This subroutine allows the user to indicate a location (using the mouse) where the robot will be placed. Once the left mouse button is clicked over a position on the screen that also has the color of the line (i.e., it is part of the maze) the robot is placed at that location. If the user keeps the mouse button clicked the robot is rotated (90 at a time) until the user releases the mouse button. The routine also uses rInvisible to set the line color so the robot can use the rSense() function to move over the line. The initial robot position is saved in the variables Rx and Ry. We will not make any use of these in this program, but they will be useful later. If you review the routine you will notice some lines are numbered. These numbers are used only for the purposes of this discussion. The code in Lines 1 to 22 ensures that the robot center is at the center of the line. Since the line is four pixels wide it is possible for the mouse to have been placed slightly off the center of the line when the user selected the position to place the robot. We need to ensure that the robot is at the center of the line because of the line following routine, which is discussed later. You should be familiar with the use of the Delay command; we use it to make it possible to control the rotation of the robot. Without the delay the mouse input will be too fast for the user to control. Lines 20 to 22 ensure that the robot s front is over a line. If it is not, the robot is turned until its front is over a line. This ensures that when it starts following the line it will not fail. 14.1.1.6 SelectGoal The mouse is used to allow the user to indicate a location on the maze where the goal is to be placed. Once the user clicks the left mouse button a small circle is drawn in red to create an obstacle at the indicated position. This obstacle is used to indicate the nal goal of the maze. Once the robot senses this object (think of it as a red cone on the ground) it will have solved the maze. The position of the goal is saved in the variables Gx and Gy. These variables are not used in this program, but will be used in later improvements of the algorithm. 14.1.1.7 DisplayMessage Most of the subroutines in this program will display a message to the user at the top left corner of the screen. These messages help the user understand what is going on and what is required. The calling routine sets a variable Message with the required text and then calls DisplayMessage, which clears the top of the screen and displays the message inside a blue rectangle.
