You just want a copy of a map already in the game to build off of? If so you just need one edit, cq_map. Lets say you want to make a copy of cata. Lookup cata in your cq_map and basically copy & paste what are not zeros.
Code:
insert into cq_map (id,name,describe_text,[COLOR="Red"]mapdoc[/COLOR],[COLOR="Blue"]type[/COLOR],portal0_x,portal0_y,[COLOR="DarkGreen"]reborn_map[/COLOR])
values
(5201,CataCopy,CataCopy,[COLOR="Red"]5200[/COLOR],[COLOR="Blue"]1075904516[/COLOR],825,1024,[COLOR="DarkGreen"]5000[/COLOR])
mapdoc - Usually the id of the original map.
type - Optional. Defines special status of a map. For example you cannot mount in cata.
reborn_map - The map you will transfer to when you revive.
You can do the same thing with cq_generator if you want same spawns on a new map.
