Thx for the reply, yes i deleted it because i actually didnt expect any more responses ( im sure its also the fault of my title ) and wanted to delete this post but i didnt know how.
And yes I searched for topics that deals with physic doors and i found one but the only thing i got from it was to use the physics joint function but thats it.
I am focused at another Game Genre now so its ok if i dont get help that fast.
But thx for the response !
