Code example
mirror.py, a script that mirrors maps in a WAD, which is included in the 0.2 release: from sys import argv from omg import * from omg.mapedit import *

def mirror(map): ed = MapEditor(map) for v in ed.vertexes: v.x = -v.x for l in ed.linedefs: l.vx_a, l.vx_b = l.vx_b, l.vx_a for t in ed.things: t.x = -t.x t.angle = (180 - t.angle) % 360 ed.nodes.data = "" return ed.to_lumps

def main(args): if (len(args) < 2): print " Omgifol script: mirror maps\n" print " Usage:" print " mirror.py input.wad output.wad [pattern]\n" print " Mirror all maps or those whose name match the given pattern" print " (eg E?M4 or MAP*)." print " Note: nodes will have to be rebuilt externally.\n" else: print "Loading %s..." % args[0] inwad = WAD outwad = WAD inwad.from_file(args[0]) pattern = "*" if (len(args) == 3): pattern = args[2] for name in inwad.maps.find(pattern): print "Mirroring %s" % name outwad.maps[name] = mirror(inwad.maps[name]) print "Saving %s..." % args[1] outwad.to_file(args[1])

if __name__ == "__main__": main(argv[1:])
