[HELP] Problem With Rotations

[HustraDev]

Hi Guy's i have been maken a mounted minigun Script and i have few problems with it

first problem is when i command to create the minigun and attach it to the Player the rotations

of the Elements { Player , Weapon } are not Match's i mean by that the Weapon not In front of the Player <

a Screen Shot of the Problem

The second Problem is I want the Weapon to move up & down for aiming i made it move but !! the problem

is the weapon and the player are Attached Of course but if there a way to move the weapon only up and down

ScreenShot :

  
 setElementFrozen(localPlayer,false) 
local x,y,z = getElementPosition(localPlayer) 
local gunCol = createColSphere ( x, y, z, 2 ) 
local vehicle = getPedOccupiedVehicle (localPlayer) 
local x2,y2,z2 = getElementPosition(vehicle) 
local screenW,screenH = guiGetScreenSize() 
local weapon 
function attach ( ) 
local detection = isElementWithinColShape ( localPlayer, gunCol ) 
    if detection then 
     weapon = createWeapon("minigun", x2, y2, z2+2) 
    attachElements ( weapon, vehicle, 0, -1.5, 0.7,0,0,180 ) 
    setWeaponClipAmmo(weapon, 99999) 
  --  setWeaponState(weapon, "firing") 
    setWeaponProperty(weapon, "fire_rotation", 0, -30, 0) 
    --setElementPosition ( localPlayer,  x2, y2-1.5, z2+2 ) 
    attachElements ( localPlayer, weapon, 0, 0, 0 ) 
    setElementFrozen(localPlayer,true) 
    toggleAllControls(localPlayer,false) 
    setElementData(localPlayer,"firedoska",true) 
    setPedRotation(localPlayer,90 ) 
    setPedAnimation( localPlayer, "WEAPONS", "SHP_Tray_Pose",0,false) 
setWeaponOwner(weapon,localPlayer) 
end 
end 
addCommandHandler ( "attach", attach ) 
  
local aimSensitivity = 330; 
  
function rotateGun_Handler(cX, cY, aX, aY, wX, wY, wZ) 
    local oX, oY, oZ, oRX, oRY, oRZ = getElementAttachedOffsets(weapon); 
    if (oRX-((cY-0.5)*aimSensitivity) > 45 or oRX-((cY-0.5)*aimSensitivity) < 30) then -- Pitch Restriction 
           oRX = oRX-((cY-0.5)*aimSensitivity); 
    end 
    if (oRZ-((cX-0.5)*aimSensitivity) > 30 or oRZ-((cX-0.5)*aimSensitivity) < 50) then -- Yaw Restriction 
            oRZ = oRZ-((cX-0.5)*aimSensitivity); 
    end 
    setCameraTarget(localPlayer,localPlayer) 
    setElementAttachedOffsets(weapon, oX, oY, oZ, oRX, oRY, oRZ); 
    setCursorPosition(screenW/2, screenH/2); 
end 
addEventHandler( "onClientCursorMove", getRootElement( ), rotateGun_Handler) 
  
           function pedrot() 
              local _,_,rZ = getElementRotation(weapon) 
              setElementRotation(localPlayer, 0, 0, rZ) 
           end 
  addEventHandler("onClientRender", getRootElement(),pedrot) 
  
function fireme() 
if getElementData(localPlayer,"firedoska") == true then 
if getWeaponState(weapon) == "ready" then 
fireWeapon(weapon) 
else return end 
end 
end 
bindKey("mouse1", "down",fireme) 
  
function unaat() 
detachElements (localPlayer, weapon) 
removeEventHandler( "onClientCursorMove", getRootElement( ), rotateGun_Handler) 
removeEventHandler("onClientRender", getRootElement(),pedrot) 
destroyElement(weapon) 
end 
bindKey("k", "down",unaat) 
setTimer(function() 
if getElementData(localPlayer,"firedoska") == true then 
addEventHandler( "onClientCursorMove", getRootElement( ), rotateGun_Handler) 
  addEventHandler("onClientRender", getRootElement(),pedrot) 
end 
    end,1000,0) 
  
  

i well be grateful for help Thanks all,

This piece of code will give you the matrix of 1 point which has a direction vector.

i'm sorry but can you explain for me more i don't get it >?

Well, you want the minigun aiming to a location somewhere in mta. (pointX2,pointY2,pointZ2 )

You also have the location of the minigun. (which you can fill in on line 31) (pointX1,pointY1,pointZ1)

When you get the direction vector from those 2 locations you can make a matrix(table).

This matrix can be used on your minigun element: https://wiki.multitheftauto.com/wiki/SetElementMatrix

How to find this vector?

local pointX1,pointY1,pointZ1 
local pointX2,pointY2,pointZ2  
  
local vectorX,vectorY,vectorZ = pointX2-pointX1,pointY2-pointY1,pointZ2-pointZ1 

I am not a pro at matrix and vectors, so it is kinda hard to explain it to you.
