Is there any possibility to make a 2 worlds, one creative one survival, and when people join creative, they have creative mod, but when they come back to the survival they should have they own inventory? Give me plugin link please. If you can help me with PEX too, i cant see where am I making mistake, please check permissions.yml here: http://pastebin.com/4BPhLMh4
I believe this question is in the wrong place this is for creating plugins not how to use them there is a plugin that can do this I think but I can't remember so just try searching around
Agreed, this is not a coding question. The plugin Multiverse-Core will manage the different player mode for each world. The plugin MultiInv will manage the inventory separation between worlds.
