setElementPosition lags onClientPreRender

[diegofkda]

Well, we all know that making a camera movement onClientRender causes desync (the camera lags).

Well, that's what's happening but onClientPreRender (with a minor intensity) so I wanted to know what's the problem (I know this isn't the best way to make what I'm making, but I'm tired with these math calculations).

object1 = createObject ( 1097, 0, 0, 0 ) 
setElementAlpha ( object1, 0 ) 
vehicle1 = createVehicle ( 441, 0, 0, 0 ) 
setElementAlpha ( vehicle1, 0 ) 
attachElements ( vehicle1, object1, 5, 0, 0.8 ) 
speed = 8 
wheelRotation = 0 
wheelRotationY = 0 
  
  
addEventHandler ( "onClientCursorMove", root, function (cursorX, cursorY, absoluteX, absoluteY) 
    if isCursorShowing ( ) then return end 
    abx = (absoluteX*1024)/sWidth 
    if abx < 512 then 
        speed2 = (512-abx)/speed 
        wheelRotation = wheelRotation-speed2 
    elseif abx > 512 then 
        speed2 = (abx-512)/speed 
        wheelRotation = wheelRotation+speed2 
    end 
  
    aby = (absoluteY*768)/sHeight 
    if aby > 384 then 
        speed2 = (384-aby)/speed 
        wheelRotationY = wheelRotationY-speed2 
    elseif aby < 384 then 
        speed2 = (aby-384)/speed 
        wheelRotationY = wheelRotationY+speed2 
    end 
    setElementRotation ( object1, 0, wheelRotationY, wheelRotation ) 
end) 
  
  
  
function onClientPreRender() 
    local vehicle = getPedOccupiedVehicle ( getLocalPlayer() ) 
        isCamera = true 
        x, y, z = getElementPosition ( localPlayer ) 
        setElementPosition ( object1, x, y, z+0.5 ) 
        x1, y1, z1 = getElementPosition ( object1 ) 
        x2, y2, z2 = getElementPosition ( vehicle1 ) 
        setCameraMatrix ( x2, y2, z2, x1, y1, z1, 0, 80 ) 
end 
addEventHandler ( "onClientPreRender", root, onClientPreRender ) 

Test it, works quite fine, but it's like it desyncs.

id say that you should use freecam resource as a base, and tear parts down/add new as you go.

and no, you are not going to make it without sin and cos.

This one works quite fine dude... but it's not what I want to do

centre = createObject ( 1097, 0, 0, 0 ) 
setElementAlpha ( centre, 0 ) 
point = createObject ( 1097, 0, 0, 0 ) 
setElementAlpha ( point, 0 ) 
speed = 0.8/15 
cx = 0 cy = -5 cz = 1 ox = 0 oy = 0 oz = 1
