• Tutorial Main Page
• Step 1: How to create a RePast model- Overview and introduction
• Step 2: The SimModel Object- The basic model object in RePast
• Step 3: The CarryDrop model- The example model this tutorial builds
• Step 4: Adding User-settable Parameters- Parameters the user can vary at runtime
• Step 5: Compiling and Running the Basic Model- Starting a RePast model
• Step 6: Default Values for User-Settable Parameters- Providing defaults for the parameters in the interface
• Step 7: Alerts in Subroutines- A crude but useful reporting method
• Step 8: The Space Object- Where agents and other model elements are located
• Step 9: The space Object in the Sim Model- Making the model object instantiate the space object
• Step 10: Initializing the Space Object- Basic setup for the landscape
• Step 11: Getting Money- A Brief Aside- Some revisions for simplicity
• Step 12: Some Visible Output- Setting up the display of the space object
• Step 13: Creating a Color Map- Defining a color map for the display
• Step 14: Generating a Display- Making RePast show the space object
• Step 15: The Agent object- Adding basic attributes to the agents
• Step 16: Creating the agents- Making the model make N agents
• Step 17: Agents in Space- Making the space object able to use the agents
• Step 18: Adding Agents to the Space- Placing the agents into locations in the space object
• Step 19: Reporting- Some basic ways to output model status
• Step 20: Displaying agents- Showing agents on the screen
• Step 21: Adding a schedule and Some Action- Creating a schedule of events
• Step 22: Another Schedule Example- Another thing that could be done with the schedule
• Step 23: Displays and Schedules- How RePast uses the schedule to update the displays
• Step 24: The Circle of Life: Agents Dying and Being Born- Making agents arrive and leave the model
• Step 25: Agents Learn Their Place- Making agents know where they are in space
• Step 26: Agents Get Money- A 'take money' function that allows agents to pluck money from the landscape
• Step 27: Agents on the Move- Making it possible for agents to move around the landscape
• Step 28: Money Changing Hands- When agents collide they exchange money
• Step 29: Probing the Space and the Agents- RePast allows the model to be interrogated in the GUI
• Step 30: Adding a Chart- Using RePast for displaying data in a chart
• Step 31: Adding a Histogram- Using RePast for displaying data in a histogram
• Step 32: Conclusion- Final comments and JavaDoc
