Who can help solve the problem with the engine, I do not know what the problem is, added vector3 no result, still writes this error

b_size = 3

function PtoT(x,y,z)
if type(x) == “userdata” then
x,y,z = x.X,x.Y,x.Z
end
return Vector3.new(math.floor(x/b_size + .5)),Vector3.new(math.floor(y/b_size + .5)),Vector3.new(math.floor(z/b_size + .5))
end

Is b size a vector value if so you cant add a regular number to them it has to vector + vector. for example
this would work

local vector1 = Vector3.new(0,2,0)

local vector2 = Vector3.new(0,3,0)

print(vector1 + vector2)

this would not work

local vector1 = Vector3.new(0,2,0)

print(vector1 + 5)

I could not solve the problem, can you give me your dc?

Lets just debug it here shall we? that way other people can input there answers to.

It’s because you’re trying to add a number to a Vector3. It isn’t possible because a Vector3 data type has 3 properties/numbers, X, Y and Z respectively while a number only has one.

If you want to specify which property to add to (X, Y or Z), you need to create a new Vector3 with the number you wish to add in it. So for example if you wanted to add to the X.

-- Vector3(X, Y, Z)

local vector1 = Vector3.new(0,2,0)
print(vector1 + Vector3.new(5,0,0))

-- result: 5,2,0

Okay, here’s the problem

b_size = 3

function PtoT(x,y,z)
	if type(x) == "userdata" then
		x,y,z = x.X,x.Y,x.Z
	end
	return math.floor(x/b_size + .5),math.floor(y/b_size + .5),math.floor(z/b_size + .5)
end

Adding or subtracting vectors with a number is not possible. You need to add a another vector3 to it like this:

local v = Vector3.new(1,7,3) + Vector3.new(3,2,4) -- X:4, Y:9, Z:7

The only kind of single number math that can work on vector3 or cframe is multiplication and division

local v = Vector3.new(15,20,5) / 2 -- X:7.5, Y:10, Z:2.5
local v2 = Vector3.new(15,20,5) * 2 -- X:30, Y:40, Z:10

function PtoT(x,y,z)
	if type(x) == "userdata" then
		x,y,z = x.X,x.Y,x.Z
	end
	return math.floor(x/b_size + .5),math.floor(y/b_size + .5),math.floor(z/b_size + .5)
end

What needs to be changed here?

#9

Does it still give you the same error when you run it?

#10

I did not understand what you wrote, can you correct this error, here is the code

b_size = 3

function PtoT(x,y,z)
	if type(x) == "userdata" then
		x,y,z = x.X,x.Y,x.Z
	end
	return math.floor(x/b_size + .5),math.floor(y/b_size + .5),math.floor(z/b_size + .5)
end
#11

As @BappoSama Said, you cannot add Vector3 Value with a regular number, you need to make a new Vector3 Value then add it.

#12

Maybe there are 2 variables named X, Y and Z

function PtoT(x,y,z)

X,Y,Z = x.X,x.Y,x.Z

when i tested it, it doesnt give that error, instead it just says 0, 0, 0 0, 0, 0 0, 0, 0,

i dont understand a single line here

#13

Looks to be a type() problem, I guess? I changed type(x) == "userdata" to typeof(x) == "Vector3", and made 3 local variables that are the same as x, y, and z.

b_size = 3

function PtoT(x,y,z)
	local X, Y, Z = x, y, z
	if typeof(x) == "Vector3" then
		X,Y,Z = x.X,x.Y,x.Z
	end
	return Vector3.new(math.floor(X/b_size + .5), 0, 0),
		Vector3.new(0, math.floor(Y/b_size + .5), 0),
		Vector3.new(0, 0, math.floor(Z/b_size + .5))
end
