This class allows you to handle matrixes without using MTA's OOP functions
This class is called POP because it doesn't use any OOP functions while keeping Lua's class structure.

Syntax

MatrixPOP MatrixPOP( element eheElement )

Required Arguments

  • theElement: The element which you wish to retrieve the matrix for.

Returns

Returns a matrix class
Returns false if the element is not streamed in, and not a vehicle, ped or object.

Code

MatrixPOP = setmetatable({},{
    __metatable = 'MatrixPOP',
    __call = function(self,ply)
        local matrixObj = {}
        setmetatable(matrixObj, self)
        self.__index = self
        
        if not isElement(ply) or (
            getElementType(ply) ~= 'player' and
            getElementType(ply) ~= 'vehicle' and
            getElementType(ply) ~= 'object'
        ) then return false end

        matrixObj.matrix = getElementMatrix(ply)
        matrixObj.rotation = { getElementRotation(ply) }

        return matrixObj
    end
})
function MatrixPOP:getRotation()
    if not self then return false end
    return Vector3(self.rotation[1],self.rotation[2],self.rotation[3])
end
function MatrixPOP:getLeft()
    if not self then return false end
    local matrix = self.matrix[1]
    return Vector4(matrix[1], matrix[2], matrix[3], 1)
end
function MatrixPOP:getForward()
    if not self then return false end
    local matrix = self.matrix[2]
    return Vector4(matrix[1], matrix[2], matrix[3], 1)
end
function MatrixPOP:getUp()
    if not self then return false end
    local matrix = self.matrix[3]
    return Vector4(matrix[1], matrix[2], matrix[3], 1)
end
function MatrixPOP:getPosition()
    if not self then return false end
    local matrix = self.matrix[4]
    return Vector4(matrix[1], matrix[2], matrix[3], 1)
end
function MatrixPOP:__tostring()
    local matrix = self.matrix
    local m1 = matrix[1]
    local m2 = matrix[2]
    local m3 = matrix[3]
    local m4 = matrix[4]
    m1 = ('{ %s, %s, %s }'):format(m1[1],m1[2],m1[3])
    m2 = ('{ %s, %s, %s }'):format(m2[1],m2[2],m2[3])
    m3 = ('{ %s, %s, %s }'):format(m3[1],m3[2],m3[3])
    m4 = ('{ %s, %s, %s }'):format(m4[1],m4[2],m4[3])

    return ('MatrixPOP: {\n%s,\n%s,\n%s,\n%s\n}'):format(m1,m2,m3,m4)
end
collectgarbage('setpause',100)

Example

Transform player's matrix into MatrixPOP

Example
addEventHandler('onPlayerJoin',root,function()
    local matrix = MatrixPOP(source)
    local position = matrix:getPosition()
    outputChatBox(('Your coordinates are: %s, %s, %s'):format(position.x, position.y, position.z)
end)
