Can someone quickly explain a script to me?
Hello, I just wanted to know what this script does in a model I found, so I can try and make something simular on my own. If you could add a comment to each line it would be appreciated. Thanks, Jhunlzeus4.
function OpenDoors()
door.AccessGranted:play()
for i,v in pairs (DoorModel.Lights:GetChildren()) do
v.brickColor = BrickColor.new("Lime green")
end
door.DoorOpen:play()
for i=0,math.pi*2,math.pi/30 do
r.Stepped:wait()
door.CFrame=ret+Vector3.new(2.5,0,2.5)*look-math.cos(i)*2.5*look
door1.CFrame=ret1-Vector3.new(2.5,0,2.5)*look+math.cos(i)*2.5*look
if string.format("%3.2f",i)=="3.14" then
door.Transparency=1
door1.Transparency=1
wait(3)
door.Transparency=Original
door1.Transparency=Original1
door.DoorClose:play()
end
end
door1.CFrame = ret1
door.CFrame = ret
for i,v in pairs (DoorModel.Lights:GetChildren()) do
v.brickColor = BrickColor.new("Institutional white")
end
end

door.AccessGranted:play() -- AccessGranted is evidently a sound. Note that play is deprecated; use Play instead.
for i,v in pairs (DoorModel.Lights:GetChildren()) do
v.brickColor = BrickColor.new("Lime green")
end
Assigns each child of "Lights" the BrickColor Lime green. Note that it should be v.BrickColor (brickColor is deprecated).
for i=0,math.pi*2,math.pi/30 do math.pi*2 is 360 degrees, so this for loop is rotating the doors 360 degrees in increments of 6 degrees (math.pi/30 == 180 degrees /30 == 6 degrees)
r.Stepped:wait() 'r' must be the RunService. Stepped runs 2x as often as wait(). :wait() is deprecated, use :Wait()
door.CFrame=ret+Vector3.new(2.5,0,2.5)*look-math.cos(i)*2.5*look
door1.CFrame=ret1-Vector3.new(2.5,0,2.5)*look+math.cos(i)*2.5*look
I'd need to see more of the script to explain this properly, though it's clearly doing rotation. Another way of rotating something is to use CFrame.fromAxisAngle(Vector3.new(0, 1, 0), angle), which you would then add to the door's position so that it stays in place. You have to do a bit more work if you want the door to rotate on its edge rather than around its centre.
if string.format("%3.2f",i)=="3.14" then This is an interesting way of determining whether the door is half-way through its rotation. A better way might be to extract the CFrame code into a function and then use two for loops separated by the contents of this if block:
local function rotate(angle)
--CFrame code here
end
local step = math.pi/30
for i = 0, math.pi, step do
r.Stepped:Wait()
rotate(i)
end
rotate(math.pi) -- this line may not be needed
--play sounds, wait(3), etc here
for i = math.pi, math.pi*2, step do
r.Stepped:Wait()
rotate(i)
end
After the for loop is done, the function returns the doors to their previous state (including lights) -- setting the light colour should really be its own function, by the way.
