hello to everyone! if you want to create doors that open is very simple .. Use the whisker version 1.005 beta
placed a door or other opening of .. (I recommend that it is dynamic)
a key place where you want ..
go on the property of the key (right click) and copy the name of the object (in this case 'key')
go on the property of the port and the name stuck on 'use key' and applied
Done!
