Bare code not inside a function just runs. On pattern start. Using @jeff 's init example is good practice though.

From personal experience, performance on 2D arrays can be very slow. You might want to make separate 1D arrays, if possible. Sometimes a frame buffer makes it easier, but sometimes it’s unneeded. For an example of frame buffer like behavior, see [Multimap multi-pattern](https://forum.electromage.com/t/multimap-multi-pattern-its-alive/1213)
