The BC2NetLogo program enables one to build models in the Behaviour Composer and to run them in NetLogo. It speeds up and automates the process of sending the model from the browser to the NetLogo program. It has many advantages over using Java applets.
Download and unzip these files then click on StartBC2NetLogo.jar inside the BC2NetLogo folder after unzipping. Note that if you have previously installed BC2NetLogo we recommend you extract these files to the current BC2NetLogo folder. If you choose to use a new folder then reset the 'folder' option in the settings dialogue after start BC2NetLogo. If you unable to install Java version 8 or you encounter errors with the new release try the previous release which can run under Java 7.
Some Mac users have reported problems with the latest release. If you have administrator rights try clicking on the StartBC2NetLogo.jar file while holding down the control button and then allow it to run. Mac users may need to run the previous release. The previous version generates annoying but harmless warnings. You can stop these warnings by changing the server to http://778.m4a-gae-hrd.appspot.com/ in the advanced settings dialogue.
If you get an error such as installation is missing required file then most likely it is because your operating system is displaying the contents of the zip file but the files have not yet been extracted from the zip archive. To fix this, copy the BC2NetLogo folder to anywhere on your computer. If you get an error such as windows doesn't know how to open this file then you need to install Java 8 (or higher) from java.com.
Just click on the StartBC2NetLogo.jar file inside the BC2NetLogo folder. We recommend you create a shortcut to StartBC2NetLogo.jar on the desktop for convenience.
After launching click on the No, show advanced settings button to customise the launch. You can alter
You should see NetLogo being launched and a web page being opened. Create your model in the browser as usual. Instead of the Run and Download tabs you'll see a Send model to NetLogo tab. When you click on that your model will be assembled and loaded automatically into NetLogo.
You can switch between as many models as you like using the My Models tab. We recommend you give descriptions to the models you are working on and click the hide check box of those you aren't. Next time you launch BC2NetLogo it will begin with the last model you worked on.
If you want to use a model that you have the URL of (either a frozen model or one that recreates the session perhaps copied from an earlier use of BC2NetLogo) then paste the URL in the first line of the Code tab in BC2NetLogo and then click 'Send model to NetLogo'.
BC2NetLogo reconstructs your session when it loads. This provides a history that you can inspect and move back and forth through versions. But the longer the history the more time it takes to load. We recommend that now and then you click on Settings and Reload without history.
NetLogo commands such as import-drawing should use the path "NetLogoData" in order to work in both applets and BC2NetLogo. If, for example, you wanted to use the file 'world.png' then
The BC2NetLogo tool stores any experiments created with the BehaviourSpace tool so that experiments are not lost when the model is updated.
There are two ways to import a model:
Click on the Share tab and copy and paste the first URL into a new browser tab or window.
Warning: experimental feature. You can edit the code and the user interface widgets and then when you send a model from BC2NetLogo the system will attempt to copy your edits to your current Behaviour Composer model.
