Can't replicate example: Grid

[fredguth]

I am trying to replicate: http://printingcode.runemadsen.com/examples/grid/only_once/

This throws an error:

var modules = grid.modules.slice();

I couldn't find modules in grid. What am I doing wrong?

Thanks @fredguth. This is an example based on an older version of Rune.js. The grid.modules array was replaced by grid.children which is used throughout the library as a scene graph. You could try rewriting this example by not copying the grid.modules array and instead getting randomized modules using the grid.getModule() function.
