World rotation

Hey guys!

I am more than sure that this is possible in mta:

but how ?

What I mean is the world rotation

Dear friend, why don't you spawn an hydra and fly on your side... please.

Dear friend, why don't you spawn an hydra and fly on your side... please.

Well...

Can you see the diffrence huh ?

local m = getElementMatrix( theVehicle ) 
local pitch = math.deg( math.asin( m[2][3] ) ) -- (-90,90) 
local roll = math.deg( math.atan2( m[1][3], m[3][3] ) ) --(-180,180) - You should only need this one (roll) 
local yaw = math.deg( math.atan2( m[2][1], m[2][2] ) ) --(-180,180) 

You can do the rest.

Oh, ya. That's all about cameraMatrix bud. Thought it was that as default?

local m = getElementMatrix( theVehicle ) 
local pitch = math.deg( math.asin( m[2][3] ) ) -- (-90,90) 
local roll = math.deg( math.atan2( m[1][3], m[3][3] ) ) --(-180,180) - You should only need this one (roll) 
local yaw = math.deg( math.atan2( m[2][1], m[2][2] ) ) --(-180,180) 

You can do the rest.

Jeez, I am dumb in Matrix functions...

So I have to set the matrix to the plane ?

I don't get it, I need to use only roll, right ?

but the damn script needs 3rd argument, then 4,5 ...

Code makes no sense

addEventHandler("onClientVehicleEnter", root,  
    function(theVehicle, seat, jacked) 
        local m = getElementMatrix( theVehicle ) 
        local pitch = math.deg( math.asin( m[2][3] ) ) -- (-90,90) 
        local roll = math.deg( math.atan2( m[1][3], m[3][3] ) ) --(-180,180) - You should only need this one (roll) 
        local yaw = math.deg( math.atan2( m[2][1], m[2][2] ) ) --(-180,180) 
            if (isPedInVehicle( getLocalPlayer() )) then 
                    setElementMatrix ( theVehicle, roll) 
            end 
    end) 

SetCameraMatrix

Use the calculated roll variable and pass it to the camera matrix (get the other values from getCameraMatrix)

What I am doing wrong.. Code is messed up

I do not neeed x, y, z or or only z ?

Damn I am dumb

addEventHandler("onClientVehicleEnter", root,  
    function(theVehicle, seat, jacked) 
        local eM = getElementMatrix( theVehicle ) 
        local x, y, z, lx, ly, lz = getCameraMatrix( theVehicle ) 
        local pitch = math.deg( math.asin( eM[2][3] ) ) -- (-90,90) 
        local roll = math.deg( math.atan2( eM[1][3], eM[3][3] ) ) --(-180,180) - You should only need this one (roll) 
        local yaw = math.deg( math.atan2( eM[2][1], eM[2][2] ) ) --(-180,180) 
            if (isPedInVehicle( getLocalPlayer() )) then 
                if ( getVehicleType( source ) == "Plane" ) then 
                    --setElementMatrix ( theVehicle, roll, y, z, lx, ly, lz) 
                    setCameraMatrix ( theVehicle, roll, x, y, z, lx, ly, lz) 
                end 
            end 
    end) 

  
addEventHandler("onClientVehicleEnter", root, 
    function(theVehicle, seat, jacked) 
        local eM = getElementMatrix( theVehicle ) 
        local x, y, z, lx, ly, lz = getCameraMatrix( theVehicle ) 
        local pitch = math.deg( math.asin( eM[2][3] ) ) -- (-90,90) 
        local roll = math.deg( math.atan2( eM[1][3], eM[3][3] ) ) --(-180,180) - You should only need this one (roll) 
        local yaw = math.deg( math.atan2( eM[2][1], eM[2][2] ) ) --(-180,180) 
            if (isPedInVehicle( getLocalPlayer() )) then 
                if ( getVehicleType( source ) == "Plane" ) then 
                    --setElementMatrix ( theVehicle, roll, y, z, lx, ly, lz) 
                    setCameraMatrix ( x, y, z, lx, ly, lz, roll) 
                end 
            end 
    end) 
  

Almost works, but camera stays in one positsion, I tryed setCameraTarget to the localPlayer and theVehicle, but if I used localPlayer, then world didn't rotate and if theVehicle, then camera stayed in one pos like without setCameraTarget..

addEventHandler("onClientPreRender", root, 
    function(thePlayer) 
        local theVehicle = getPedOccupiedVehicle ( localPlayer ) 
            if not ( theVehicle ) then return end 
                local eM = getElementMatrix( theVehicle ) 
                local x, y, z, lx, ly, lz = getCameraMatrix() 
  
                local pitch = math.deg( math.asin( eM[2][3] ) ) -- (-90,90) 
                local roll = math.deg( math.atan2( eM[1][3], eM[3][3] ) ) --(-180,180) 
                local yaw = math.deg( math.atan2( eM[2][1], eM[2][2] ) ) --(-180,180) 
                   -- if ( getVehicleType( source ) == "Plane" ) then 
                        setCameraMatrix ( x, y, z, lx, ly, lz, roll) 
                        --setCameraTarget( theVehicle ) 
                    --end 
            end) 

Still don't know what's the problem

hey i haev something like that too but when i exit the vehicle the camera matrix is not set to rthge player again...

Holy hell that's overly complicated... I made this as a test one. Works fairly well IIRC.

local function clientPreRender() 
        if not isPilotingCompatibleVehicle() then 
                return 
        end 
        
        local vehicle = getPedOccupiedVehicle(localPlayer) 
        local cameraX, cameraY, cameraZ = getPositionFromElementOffset(vehicle, 0, -7, 4) 
        local lookAtX, lookAtY, lookAtZ = getPositionFromElementOffset(vehicle, 0, 0, 2) 
        local _, rotY= getElementRotation(vehicle) 
        setCameraMatrix(cameraX, cameraY, cameraZ, lookAtX, lookAtY, lookAtZ, (rotY*-1)) 
end 
addEventHandler("onClientPreRender", root, clientPreRender)

yes but at the andromada you should deative it Nacktrox

hey i haev something like that too but when i exit the vehicle the camera matrix is not set to rthge player again...

Add this line to your script

addEventHandler("onClientPlayerVehicleExit", root, 
    function() 
        setCameraTarget(localPlayer) 
    end 
)
