- vector2: a 2D vector, used in the Vector2 class.
- vector3: a 3D vector, used in the Vector3 class.
- vector4: a 4D vector, used in the Vector4 class.
- matrix: a matrix, used in the Matrix class.

Example
This example shows a function that can be used to work around the impossibility to transfer vectors as arguments when using triggerClientEvent and triggerServerEvent, by converting them into a table which can be used safely.
function safeArgsForTransfer(...)
local args = { ... }
for index, arg in ipairs(args) do
if type(arg) == "userdata" and getUserdataType(arg):match("vector") then
-- Transform every kind of vector userdata to a table which can be transfered safely
args[index] =
{
arg:getX(),
arg:getY(),
arg.getZ and arg:getZ() or nil,
arg.getW and arg:getW() or nil,
-- Extra field to distinguish from normal tables
["isVectorWorkaround"] = true
}
end
end
return unpack(args)
end
