Latest version Released: Jun 7, If not, there is a batch file that you can use to do this.
Put it in the same directory as the jar file and double click it to run the world builder. This file is in the distribution zip in a Windows directory. If you have trouble, create a file named WorldBuilder.
It is written in Java 1. The button highliting doesn't happen though. If you work on a Macintosh under OS 9, there is an application shell for the world builder. It is in the Macintosh folder in the distribution zip. Put it in the same folder as the KarelJRobot. The Macintosh OS 9 world builder application shell and the Windows batch file mentioned just above are now in the zip in separate folders.
Move the file appropriate to your system to your working directory the one that contains KarelJRobot. You can then just double click to run the world builder.
On Mac OS X, double clicking the jar itself should work. It may also on Linux, but I have no way to test it. The simulator now shows the mouse's position in the main window as the closest corner.
The coordinates are in the control dialog. Note that as before the control dialog has a close box, but it is inactive. The dialog may be resized, however, for fine grained speed control. Robots are now shown slightly differently after they turnOff. They have a greyed out look.
There are two new messages understood by UrRobots and hence by all robots. You can make a robot invisible at the next drawing of the screen by sending it a message like. You can make it visible again with setVisible true. You can also ask an UrRobot if it is currently visible with the predicate isVisible. Note especially that predicates are only introduced for Robots Chapter 5 in the text. These new instructions are useful, however, if you have a lot of robots, only some of which are of interest at a given moment, or if you want to remove robots from the screen after they turnOff.
Thanks to Don Slater of Carnegie-Mellon for suggesting this. Even though it is one code base there are really two applications here. The world builder is separate from the simulator. You can run them at the same time, however. You can even keep the world builder open as you run your Robot programs in the simulator. You will need to save the world in the world builder using a name known to the Robot program to do this effectively, however. The Robot program only gets a new copy of the world when it executes readWorld.
Note that readWorld will merge the contents of the file into the existing world, not replace it. Use your browser to open the index file. I started out to build a world builder, but got carried away. The simulator part has a new feature that you can use if you like, though you don't need to. You can still put robot commands and world building commands into a Java main and it will work.
However, in looking for something simpler for students to use, I included the following:. Build a new class that is in the kareltherobot package and implements the RobotTask interface.
This extends Directions, so you don't need to implement both. Give this new class a method with protocol public void task. Put all of your robot commands and any world commands inside this task method. Here is an example:. Now, build a project that includes the above file and the KarelJRobot.
In the last case, you will be prompted for the name of the class and you can respond with either Test1 or kareltherobot. This assumes you have put your classes into package kareltherobot, which you should do in any case.
For each of these the task will be run AND you will be prompted at the end to ask if you want to run it again without restarting. Any response that does not begin with the letter 'n' or 'N' will be treated as a yes--even just a return. Before it runs again the world will be automatically cleared and the task then re-executed, including any world setup commands.
There are two sample such test programs packaged in the distribution zip. Note that on the Macintosh there is no command line normally, so the last form of the run is equivalent to double clicking on the application that your IDE Codewarrior, for example creates. Also, if you run a task in which all robots run in separate threads, the prompt for rerun will come immediately after the robots are created.
This can be a little disconcerting, as the task hasn't run yet and you are being asked to run it again. Eventually the robots will complete and your response to this prompt will have effect. NOTE: March 15, KarelRunner was called KarelTest until recently. RobotTask was previously called RobotTester. This is a change for naming consistency with other items see below. Also note that a RobotTask class should not also extend a robot class.
These task classes only work if they have a no-argument constructor available and usually robot classes do not have such a constructor. RobotTasks are to exercise robot classes, not to BE robots. The simulator now shows street and avenue numbers if you have up to 50 streets. If you have a small screen, this will be effective only for smaller numbers, however. Added Aug. Karel J. Robot now comes with a testing framework based on JUnit. It permits test first programming.
You can learn more about this idea and how to use it on the Test Infected Programming page. There is a new June, way to give executable specificiations of Karel J Robot programs for student exercises and to exercise and test programs as they are written. It is important to note that this is an executable specification. You execute it by pushing a test button on the page that contains it not here, visit the link above.
