サンプルコード

起動 Maze.new

require 'sketchup.rb'


class Maze
	def build_maze(break_walls, maze)
		model = Sketchup.active_model
		entities = model.active_entities
		path = Sketchup.find_support_file "Fence Picket Straight Wide.skp" ,"Components/Landscape/"
		definitions = model.definitions
		compo = definitions.load path
		rows = maze.size
		cols = maze[0].size
		for i in 0..cols - 1
			putc '_'
			putc ' '
		end
		puts
		for i in 0..rows - 1
			putc '|'
			for j in 0..cols - 1
				if break_walls.any? { |a, b|
					a == [i, j] && b == [i + 1, j]
				}
					putc ' '
				else
					putc '_'
					point = Geom::Point3d.new 70 * i, 70 * j, 0
					trans = Geom::Transformation.new point
					entities.add_instance compo, trans
				end
				if break_walls.any? { |a, b| 
					a == [i, j] && b == [i, j + 1]
				}
					putc ' '
				else

					trans = Geom::Transformation.new point
					ins = entities.add_instance compo, trans
					rot = Geom::Transformation.new point, Z_AXIS, 90.degrees
					ins.transform! rot
				end
			end
			puts
		end
	end
	def fill(fm, to, maze)
		rows = maze.size
		cols = maze[0].size
		for i in 0..rows - 1
			for j in 0..cols - 1
				if maze[i][j] == fm
					maze[i][j] = to
				end
			end
		end
	end
	
	def get_random_array(initAry)
		randAry = Array.new
		while(initAry.length > 0)
			randAry.push(initAry.slice!(rand(initAry.length)))
		end
		return randAry
	end
	
	def make(rows, cols)
		maze = []
		for i in 0..rows - 1
			maze << (0..cols - 1).map { |j|
				cols * i + j
			}
		end
		pairs = []
		for i in 0..rows - 1
			for j in 0..cols - 1

		end
		break_walls = []
		pairsshuffle = get_random_array(pairs)
		pairsshuffle.each { |a, b|
			x = maze[a[0]][a[1]]
			y = maze[b[0]][b[1]]
			if x != y
				break_walls << [a, b]
				fill(x, y, maze)
			end
		}
		build_maze(break_walls, maze)
	end
	def initialize
		make 10, 10
	end
end

以上。
