Examples

This page contains a couple of example scripts written in Arena. These should serve to give an impression of how Arena scripts look and feel like. Source code for each example can be downloaded and also viewed as HTML.

Your help is needed in making this section grow! If you have written a small Arena script that illustrates some part of the language or shows how to solve a common problem in Arena, please consider sending it to the maintainer for inclusion here.
