Hi, I've tried to make a "Surface Blast Doors", but my script everytimes make the doors open BUT not open. I use CFrame Lerp and it makes that like the doors are open and not moving, but for roblox it moves, it moves only like a 0.001 stud and I don't know how to fix it. Please help. There is my script.

01local db = false
02local open = false
03 
04script.Parent.ClickDetector.MouseClick:Connect(function()
05    warn("Checking if SBD's are open..")
06    if open == false then
07        warn("SBD's closed, checking if in move!")
08        if db == false then
09            warn("SBD's not moving. Opening SBD's!")
10            db = true
11            local finish = script.Parent.Parent.PrimaryPart.CFrame*CFrame.Angles(0,math.rad(90),0)
12            for i = 0,1,.00001 do
13                local cfm = script.Parent.Parent.PrimaryPart.CFrame:Lerp(finish,i)
14                script.Parent.Parent:SetPrimaryPartCFrame(cfm)
15                wait()
16            end
17            open = true
18            warn("\nSBD's SUCCESSFULLY OPENED!")
19            wait(1)
20            db = false
21            warn("\nPrepared to close!")
22        end
23    elseif open == true then
24        warn("SBD's opened, checking if in move!")
25        if db == false then
26            warn("SBD's not moving. Closing SBD's!")
27            db = true
28            local finish = script.Parent.Parent.PrimaryPart.CFrame*CFrame.Angles(0,-math.rad(90),0)
29            for i = 0,1,.00001 do
30                local cfm = script.Parent.Parent.PrimaryPart.CFrame:Lerp(finish,i)
31                script.Parent.Parent:SetPrimaryPartCFrame(cfm)
32                wait()
33            end
34            open = false
35            warn("\nSBD's SUCCESSFULLY CLOSED!")
36            wait(1)
37            db = false
38            warn("\nPrepared to open!")
39        end
40    end

(The doors itself are the ClickDetector, I made that just for testing.)

The problem is that you are not creating the CFrame from the start point.

Lerp is used to get the % between a start and end values (a CFrame is a list of value) in the value range 0~1 (1 being the end value). You are changing the start point each time resulting in a glichy effect.

Do not change the start or end points while doing the lerp.

1-- create a variable of the start point as it should not change
2local start = script.Parent.Parent.PrimaryPart.CFrame
3local finish = start * CFrame.Angles(0,-math.rad(90),0)
4 
5-- lerp from start to finish point
6for i = 0,1,.00001 do
7    cript.Parent.Parent:SetPrimaryPartCFrame(start:Lerp(finish, i))
8    wait()
9end

Hope this helps.

Thank you so much, you helped me a lot! zeptak 4 — 6y
