[SOLVED] Calling a function without parenthesis?

Hi there! So I found a script somewhere in the toolbox and decided to see how it is written. However in the script I saw that some functions are called without parenthesis and I don't get how. Can someone explain? Any help appreciated :)

It is a Module Script that looks something like this:

01local module = {}
02 
03local function disablePlacement(plane) -- Function 1
04    if (currentPlane) then
05        renderConnection:disconnect()
06        renderConnection = nil
07        currentPlane = nil
08        module.currentPlane = nil
09        currentEvent:Destroy()
10        currentEvent = nil 
11 
12        if (currentTexture) then
13            currentTexture:Destroy()
14            currentTexture = nil
15        end
16 
17        for i = 1, #currentObjects do
18            local object = currentObjects[i]
19            object.model = nil
20            currentObjects[i] = nil
21        end
22 
23        unbindInputs()
24    end
25end
26 
27local function setLoading(plane, isLoading) -- Function 2
28    if (plane.loading == isLoading) then
29        return
30    end
31 
32    plane.loading = isLoading
33 
34    if (plane == currentPlane) then
35        if (isLoading) then
36            for i = 1, #currentObjects do
37                setState(currentObjects[i], states.loading)
38            end
39        else
40            for i = 1, #currentObjects do
41                setState(currentObjects[i], states.neutral, true)
42            end
43 
44            obstacleCollision()
45        end
46    end
47end
48 
49 
50module.new = function(base, obstacles, grid)
51    local plane = {}
52    plane.base = base
53    plane.obstacles = obstacles
54    plane.position = base.Position
55    plane.size = base.Size
56 
57    if (math.floor(.5 + plane.size.X/grid) % 2 == 0) then
58        plane.offsetX = -grid/2
59    else
60        plane.offsetX = 0
61    end
62 
63    if (math.floor(.5 + plane.size.Z/grid) % 2 == 0) then
64        plane.offsetZ = -grid/2
65    else
66        plane.offsetZ = 0
67    end
68 
69 
70    plane.stateEvent = Instance.new("BindableEvent")
71    plane.stateChanged = plane.stateEvent.Event 
72 
73    plane.grid = grid
74    plane.enable = enablePlacement
75    plane.disable = disablePlacement -- Calling function 1 without parenthesis??
76    plane.rotate = rotate
77    plane.place = place
78    plane.setLoading = setLoading -- Calling function 2 without parenthesis??
79 
80    return plane
81end
82 
83module.setLoading = setLoading
84module.currentPlane = false
85 
86return module

NOTE: These are only some parts of the script, not the full version.

Again, any help will be appreciated :)

My question here is that it doesn't? Please explain further NarwhalAndMe 141 — 3y
