World rotation

FuriouZ · August 4, 2014

Hey guys!

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

but how ?

What I mean is the world rotation

tosfera · August 4, 2014

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

FuriouZ · August 4, 2014

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

Well...

Can you see the diffrence huh ?

Addlibs · August 4, 2014

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?

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

* not working

Edited August 6, 2014 by Guest

FuriouZ · August 5, 2014

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

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

Woovie · October 31, 2014

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

-- Changes the camera position on pre-render (to avoid stuttering) 
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

The function getPositionFromElementOffset is missing too

@edit: Mine code example also moves the camera away, when u accelerate.

yoya99 · November 9, 2014

yes but at the andromada you should deative it Nacktrox

Tails · November 9, 2014

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 
)

World rotation
