How to make PVE server?

I know, its stupid question, i just want to be sure how to do it right.
I know its:
server.pve true/false (in console)
but i think it stays until server restart, than it change to PVP.Do i need to put it in config file?

I saw on several forums that on PVE servers u cant destroy buildings.Is that true?How does it work, i can destroy my own buildings but cant destroy others?
Can u use c4 or rockets also to do damage on buildings?

Thanks.

Just do not see the grace in PVE server.
The only small challenge that will have will be to kill a bear.
The game still weak and in PVE is not challenging NPC.

I am running creative server and i need PVE enabled so people cant die or loose their buildings

Can some PVE server owner check this for me:

server.pve true - people loosing health by hitting anything or anyone?
server.pve false - all back to normal

Some peeps just like to build

Add


+server.pve 1

at you startup server script
