Is there anyway I can get the metatable of for example Instance.new("Part") even though the metatable is locked?

you can make your own

myColor3 = {
__index = function(t,k)
if k=="R" then return t.r end
if k=="G" then return t.g end
if k=="B" then return t.b end
return nil
end;
}
function myColor3.new(r,g,b)
return setmetatable({r=(r or 0),g=(g or 0),b=(b or 0)},myColor3)
end
function myColor3:__tostring()
return table.concat({self.r,self.g,self.b},",")
end
--etc

print(myColor3.new(1,1,1))

or you can get all of the functions of the regular color3

local b = Color3
Color3 = {}
for k,v in pairs(b) do
Color3[k] = v
end

--and now you unlocked Color3 for editing

{r=(r or 0)

what is this

"r=(r or 0)"

wouldn't that be true or false?

or picks the first value that is not nil or false

and picks the last value if all is not nil or false, returns false if not

so

2 and 0
>0
nil and 0
>false

2 or 0
>2
nil or 0
>0

and/or operators in lua work like this:

a and b
if a then return b, else return a

a or b
if a then return a, else return b

that doesn't work properly, I inserted my own method there and it doesn't work. Also "Color3[k] = v" just throws an error, you need to actually copy the table and set Color3 to it.

@TimeTicks

Color3:lerp(Color3.fromHSV(h,s,v),alpha)

No the actual function lerps through HSV color space and not through RGB color space like the roblox function does.

Well you said you wanted LerpHSV, is that not what you want now?

No I made my own custom function that doesn't work like the roblox Color3:lerp(). Look up HSV interpolation and compare it to RGB interpolation

then literally just do this and add your custom function


local b = Color3
Color3 = {}
for k,v in pairs(b) do
Color3[k] = v
end

function Color3.wow()
print("WOW")
end

Color3.wow()

how does this possibly error

But it is still not a method of the Color3.
It is just a function in the Color3 table which does not help at all. Cause it doesn't work like a method on something like Color3.new(1,0,1):LerpHSV(Color3.new(0,1,0),alpha)

instead

and you can just edit Color3.new()
