Hi you all I am new to this forum and also quite new to ruby...I have some PHP knowledge but I'm definitely no pro in programming... Now I have a project at school...I will try to explain it as short as possible... I need to generate a grid, let's say of 196 cells (grid of 14x14), I'm now generating it with an array: grid = [1, 2, ..., 195, 196] 1. first of all is there a way to somehow automatically generate an array of following numbers or other characters because when I later on plan to change the gridsize it would be nice if this can be filled automatically... 2. The grid is then intended to be used for a land use project...first of all I have to give particular cells the characteristics of infrastructure, for instance all the cells on the right hand side (cell 14, 28, 42, 56 etc.) of the grid form a road from top to bottom... 3. when there are enough roads for a good infrastructure (to be judged by myself) i need to fill the open areas with houses...each cell in these areas should have some location characteristics like distance to infrastructure...when a cell meets some demands it can then be located as a suitable cell for building some type of house on it... I see that this is a bit much too ask in one time and I'm not expecting a totally worked out answer to all my questions but maybe someone can help on the way and after that I can come back if I encounter problems... Thanks very much you all, hope you can help in any way! Greets -- Posted via http://www.ruby-forum.com/.
