How is it that a game can know a parameter of a function without assigning it?
function RayIgnoreCheck(hit, pos)
if hit and (hit.Transparency > 0 or hit.Name == "Bullet" or hit.Name == "Handle" or hit:IsDescendantOf(char)) then
return true
end
return false
end
so you know how it says if hit but how does it know how does the game know what hit is and what pos is?

For a ray something like "local hit, position, normal = Workspace:FindPartOnRay(ray, ignore)" where hit is the part that was hit, position is the center of the ray and Normal returns normal to the surface that was hit (if hit). The ignore would obviously be defined locally above this line. ABK2017 406 — 5y

Methods (:) automatically pass `self` which is responsible for why it knows the parameter. EpicMetatableMoment 1444 — 5y

When you run a function, you may want to add stuff to the stuff Inside the function... For that reason there are parameters!!
here is an example:
local function printText(Some_Random_Text)
print(Some_Random_Text)
end
printText("Hello world")
Like I said, you need to define whatever is in the parenthesis for later use.
More examples:
local function random(a)
print(a)
end
random(math.random(0,10))
In this example, math.random is the parameter.
Basically parameters are a random variable that soon gets defined when you call the function.
