Hello i am astraxrazor.
I am the owner of a minecraft server.
The server is an space based server, but he isnt finished .
While im was searching for some cool plugins for my server, i founded yours.
At time ago i asked an developer to create a kind of simular plugin for me but he hasent done ist because my whishes were to dificult.
Now i also think that my whishes were not realistic.
But i have some great idears for you:

First:
I think its not a good idear to test for player movment.
Its much easyer an much more realitic to make a "timer" that ticks down (i hope you understand me).
Because in reality a person who is i the space will needs oxygen all the time.

Seccond:
How i told you in my pm i think it would be a great thing if there will be some blocks which makes an oxigen bubble but only if they are filled with an oxygen tank.

Thirdly:
It would be realy nice (but i think its not realistic ) if there would be a way to connect blocks which produce oxygen to blocks whichs spread oxygen (i mean the blocks which i described in seccond).
Like oxygenpipes.

Fourthly:
It is not realistic to take a oxygen tank and to fill it with air whilst punching a block which produce oxygen.
Maybe there shoud be some kind of block wich collects oxygen if there are blocks around it whichs produce oxygen naturally.

My last idear was that their shoud be a way to "create" oxygenfilled regions (like it is described in one of the comments) but with one condition.
Namely a percentage of naturally oxygen producing blocks.
This idear is for atmospheres of planets which i want to create.

I hope you like this idears.
Pleas give me an answer if you like them or not.
greeting astraxrazor

PS: please pardon my bad english and ask if you dont understand some things
