How would I make this door opening script more efficient and universal?

Asked 207 views1 answers

I got this script that this site helped me make, but every time I make a new door, I have to tinkle and tweak the CFrame positions so it will open and close (and be in the correct place.) It becomes a hassle, and I dread the next time a level requires me to make a door

So, I want to make this door universal and be able to use in any position or place, but me being a noobie, I don't know where to start!

local Door = script.Parent
local distanceToOpen = 10
local used = false

function onClicked(playerWhoClicked)
    local dist = playerWhoClicked:DistanceFromCharacter(Door.Position)
    if dist <= distanceToOpen and not used then
        used = true
        Door.CFrame = CFrame.new(34.6, 12.3, 105.1)*CFrame.Angles(0,math.rad(-90),0)--opened
		print("door opened")
		wait(3)
		used = false
		Door.CFrame = CFrame.new(32.1, 12.3, 103.4)*CFrame.Angles(0,math.rad(0),0)--closed
		print("door closed")
    end
end

Door.ClickDetector.MouseClick:connect(onClicked)

(Script is inside an object (the door) and relies on a ClickDetector)

Think: What is changing whenever I make another door? The Door Position... Does that have a relation to the CFrames that the door moves to when closing and opening? Yes, those CFrames can relate directly to the door

http://wiki.roblox.com/index.php?title=CFrame#Methods

Use ToObjectSpace(DoorCFrame) which will return the difference in CFrame of a position compared the the Door's CFrame.

I'll give some code example:

doorPos = game.Workspace.Door.CFrame --you can reset this to the exact hierarchical position of the door in your place

--next we can get the difference of the open and close CFrames relative to the door using ToObjectSpace

currentOpenPos = CFrame.new(0, 5, 0) -- The current open position you are using in the above script

openPos = currentOpenPos:toObjectSpace(doorPos) --We can get the difference

--With this information, simply add the difference to find the new open door position whenever you change the position of a door

newDoorPos = CFrame.new(0,5,0) --Change this to what you want

newDoorOpen = newDoorPos + Vector3.new(openPos.X, openPos.Y, openPos.Z)

--Then to change the rotation, simply multiply by CFrame.Angles(keep in mind we are using radians
--This final line is giving me errors, I'm trying to get the rotation of openPos and in a sense add it to this CFrame. In the meantime you will have to make up your own rotations each time, should remain constant for this projec though
newDoorOpen = newDoorOpen.CFrame.p * CFrame.Angles(0, math.pi/2, 0)

--CFrame.p returns the 3D position of the object in vector3 form

I'm sorry, but I do not know where to go from here. Good idea with Vector, I knew I had to use math somehow (P.S. I didn't downvote you, and whoever did should contribute and answer this as well >:( )

Its fine, I probably deserved it, I'll explain it better with some code...
