CombinedWorld
Switch between dimensions as if they are different servers.
About this Mod
Switch between dimensions as if they are different servers.
Your inventory and most of the properties would be saved and loaded when you switch dimensions.
Here, we categorize dimensions as such:
Group - all dimensions in the same namespace, you can travel without changing inventory.
World - dimensions that are overworld, nether or the end of the same prefix, they are considered as the same dimension by the mod, but the mod can remember the last dimension you were in when you leave this world.
Dimension - elementary dimension as the game define.
You must modify level.dat manually and add dimensions as you want(since I don't know what kind would you like).
If a dimension is named as xxx:yyy_overworld or xxx:yyy_the_nether, you can lit a nether portal there and go to corresponding dimension.
If a dimension is named as xxx:yyy_the_end, it would be used as the end of xxx:yyy_overworld and xxx:yyy_the_nether and an end portal would send you back to xxx:yyy_overworld.
Make sure you have created these dimensions if you want these functions, otherwise don't use these suffixes.

To customize seed of a specific dimension, simply add a Long field to data/seed/ in it, set the key to the identifier of the dimension, and value to be the seed. If seed is not set, seed of the whole server would be used.
To customize default gamemode of a specific group(namespace), simply add an Integer field to data/gamemode/ in it, set the key to the namespace of the group, and value to be the numeric ID of the gamemode(0=survival, 1=creative, 2=adventure, 3=spectator). If gamemode is not set, gamemode of the whole server would be used.
