Why doesn my project work in the new version of StarLogo (version 2.0+)?
There are two possible reasons for your old project not working in the new version of StarLogo. The first reason is that the command for pressing buttons from the command center has changed. Before you only had to enter the name of the button. For example, if your button was named “go”, you simply had to enter “gobutton”; however, in the new version you will have to enter “startgobutton”. In other words, you have to append the word “start” to the beginning of code calling for pressing buttons. This may have to be done manually in old projects and then resaved. The second reason your project may not work in the new version of StarLogo is that version 2.0 implements tighter error checking for code in the command center. One of the most common errors is the code: “(3 +5)”. This error used to be ignored in the old StarLogo. However, in the new version, this error will stop a project from compiling properly. Make sure your old code is free from these errors.
