How to edit maps in ultrono arena:

1.  Make sure that newmap.cfg and edit.cfg are in your ua/ folder.

2.  Set an administrator password on your localhost-only server (for example, sv_adminpass "local"), connect your UA client, and gain admin privileges by typing "admin local".

3.  Choose a name for your new map, say "test1.map".  In the console, issue the commands

  set _mapfile test1.map
	exec newmap.cfg

4.  See the instructions printed at the top of the screen.  Most importantly, the buttons 1 and 7 (or End and Home on the keypad) serve as "save" and "reload" keys.  The editing cycle is as follows:

  - Create or modify some geometry.
	- Hit 1 when you're satisfied to save the changes you've made.
	- Hit 7 to reload those changes on the server, so that e.g. collision detection works as it should.

5.  If you quit UA and want to edit an existing map, connect to your localhost, gain admin privileges, issue the following console commands and then hit 7 and K.

  set _mapfile test1.map
  exec edit.cfg

6.  If you change maps on the server while editing, you will often respawn somewhere outside the map.  Similarly, if you fall off a map-in-progress, you will be stuck in the deep void.  Hit K (or type "kill" in the console) to remedy this.  If, after done editing, you would like to use a UA server for normal purposes, type "rc set debugmap 0" so that players are respawned between maps in the usual way.

7. If UA crashes between editing sessions (sorry!), delete uaconfig.cfg and try again.  This has always fixed it for me.
