Hello,
First time poster here, so here it goes, the problem i am having is that i can grab items which float in front of player in FPS camera it works all fine i can go around with it i can throw items, the next thing is Doors, as i tried to have same mechanism for doors as items just that i use a hinge that is blocking player from taking the door and walking with it, so the doors are unbreakable. i am currently testing the script with the game so thats why i has some random key inputs but its inputed as it is written in the scripts.
The result i want is that when i press LMB the door pushes so it opens, when RMB is hold in the range of the use door / open door it drags near player so it can be closed as well, as of now it is only possible to open but cannot close, to close i must go behind the door and push it back… that is a big bug for the game as the doors arent supposed to be opening in so much angle.
the whole point with the door push and pull system is that the player has the power to open door slowly or fast as well as only a little and the whole way and all in between for more realistic experience.
the same will work with windows in the future and other hinged doors such as trapdoors, and other entrances.
kind a new to scripting have been learning C# Sharp for 2 weeks only now so kind of a newbie still 
Hope to get this fixed as it is important aspect of the game as the game has to do a lot with different entrances as it is a horror FPS horror game
Also like said i havent scripted so much in my life yet so i know its possible but i am not able to cut back on the script and make it shorter :-/ any advice on that would be also helpful
