Mr. Maverrick

So I have a few hours in this game and I really like and enjoy it and I asked a friend if we want exploration mode together and we build a nice little base but then we wanted to redo it from the scratch but breaking blocks takes ages so I thought I just put down the barrier generator and destroy the blocks with the hammer but then and yes I know the following.... My friend can't either build stuff place stuff or interact with stuff as long my barrier is active. So far so good but can he somehow build and do stuff within my barrier range? Or is there a way to remove the barrier? Because always switch it on and off and on and off is kinda annoying same for doin it without the barrier. If no will someday comes a patch where this is possible? Like give people you decide who can or can't do stuff under your barrier?

Thanks mate

Oh ok guess I try this then but how exactly I'm doing this?
