Building the CarryDrop simulation in Eclipse Creating a new project with existing code from John Murphy’s RePast tutorial
Preparation • For these slides you will need: • The Eclipse IDE installed and running. • Access to the source code from John Murphy’s RePast tutorial, step 14.
Creating a new project • Start Eclipse • Go to File -> Project • In the New Project dialog box select “Java Project” and hit the Next button • In the next screen, name the project and choose a location. • Leave the default setting for the project layout.
Creating a new project cont. • Add RePast to the build path under the “Libraries” tab. • Click the “Finish” button. Please refer to Installing Repast in the Eclipse IDE under section IV.B of the RePast Study Group homepage for details on adding the RePast jar to a project build path.
Creating a new class • Now that we have the project established we can add the first new class. • Go to File->New->Class. • A New Class window should appear. • For the Package, enter “demo” • For Name, enter CarryDropModel. • Leave all other settings at default values. • Hit the “Finish” button.
The first class: CarryDropModel • Go to step 14 of Murphy’s tutorial. • In your browser, select all the Java code for the CarryDropModel class and go to Edit->Copy • In Eclipse, select all the pre-written code in the new CarryDropModel
The first class: CarryDropModel • Go to Edit->Paste. • The code from the tutorial webpage should have now replaced the pre-written code.
Adding the other classes • Save the CarryDropModel in Eclipse and it is done • Repeat the previous steps to create new classes, copy code from the tutorial, and paste it in Eclipse for both CarryDropAgent and CarryDropSpace. • The CarryDrop simulation is now in Eclipse and ready to be run.
The CaryyDrop simulation • To start the simulation, go to Run->Run… • In the Run dialog box CarryDropModel, • make sure the Project name is correct • the Main Class box has demo.CarryDropModel • Hit the “Run” button
The CarryDrop Simulation • RePast will start • Press the Initialize button • The CarryDropModel window will appear with the initialized money space.
