To create your own map you need to be at starting map which is map 0.0 and have level at least 50. I added these conditions to prevent abuses.
Enter in chat window this command to create your own map:
Now you can go there using command:/createmymap
To go back to map 0.0 use the same command./gotomymap
To start editing map use this:
or press tabulator key if you are using PC client./e
The created map has standard size. Later I will add option for defining map size and default background.
At this moment you can create only one map per account maybe later I will increase this limit. I am thinking also about
option for giving access to other players to our map.
If the map will be good then I will add it to the game. I am going to improve map editor to support adding portals, signs, monsters, etc.
