      While functionally it seems to be completely ok (although I currently can't remember the case where vec3 would be needed in Gideros, but I don't exclude the possibility that it might)
      but you are not utilizing the power of Gideros provided OOP approach.

      While you do it right in the constructor, assigning x,y and z to the self as instance properties, you then go completely other way around and plugin your own method through metatable and do not reuse the self instance properties at all.

      It could all be as easy as:
      Vector3 = Core.class()
 
function Vector3:init(x, y, z)
	self.x = x
	self.y = y
	self.z = z
end
 
function Vector3:toString()
	return self.x .. "," .. self.y .. "," .. self.z
end
 
function Vector3:add(b)
	if type(b) == "number" then
		self.x = self.x + b
		self.y = self.y + b
		self.z = self.z + b
	else
		self.x = self.x + b.x
		self.y = self.y + b.y
		self.z = self.z + b.z
	end
end
 
function Vector3:getLenght()
	return math.sqrt(self.x*self.x + self.y*self.y + self.z*self.z)
end
 
--etc
      But thats just my suggestion. Cheers ;)

      Thank you!
      3D vectors want to use in a small engine, rotation of a 3D shape. as flash old technology (flash7). Again, I am new, gideros saw 3 days ago) and Lua is also seen. mainly programmed in flash.soon I'll show 3D shape )

      Oh, I forgot gideros chose to porting games:

      but for some reason became interested in 3D :)

      I'm really interested in this, Vector3 would be really useful and should be native imho, especially for v2 of Gideros.

      Yes, I agree! vecor2&3 should be native) soon I'll show 3D shape with environment maping. Although to start make flat shading)
