Head Rotation

[Sasu]

I have this script:

function onClientLookAtRender() 
    for i,v in ipairs(getElementsByType("player")) do 
        local rotcam = math.rad (360 - getPedCameraRotation (v)) 
        local xpos,ypos,zpos = getPedBonePosition (v, 8 ) 
        local xlook,ylook,zlook = xpos - 300*math.sin(rotcam), ypos + 300*math.cos(rotcam), zpos 
        setPedLookAt (v, xlook, ylook, zlook, -1) 
    end 
end 
addEventHandler ("onClientRender", root, onClientLookAtRender) 

But I saw that it does not work. The localPlayer works correctly but the other players only see to north, I think. Can you help me?

Because client-side functions are only triggered to the remote client. You need to make it synchronize it with all players by hooking client- and server-side with a timer. Or you could also set element data on each player with the head rotation and in the render function you fetch all streamed in and on screen players and their head rotation and then set it.

[Sasu]

You mean to do a loop of all player and then use triggerClientEvent for each player?

[IIYAMA]

Well triggerClientEvent or elementdata.

- TriggerClientEvent uses 3+ times more data but you can choose what player receives the data. (the closes players)

- ElementData uses less data but it will send to all players directly.

It depends on this:

- 30+ players and for big maps (or full gta san) use triggerClientEvent.

- Less players and players are all in the same part of the world, use elementdata.

Use the command: /shownetstat to choose between those ways of data transfer.

I tried with this but it doesnt work:

function onClientLookAtRender() 
    setElementData(localPlayer, "CRotation", getPedCameraRotation(localPlayer)) 
    local cx,cy,cz = getPedBonePosition (localPlayer, -- s8) -->
    setElementData(localPlayer, "CRotationX", cx) 
    setElementData(localPlayer, "CRotationY", cy) 
    setElementData(localPlayer, "CRotationZ", cz) 
    for i,v in ipairs(getElementsByType("player")) do 
        local CCam = tonumber(getElementData(v, "CRotation")) or 0 
        local rotcam = math.rad (360 - CCam) 
        local xpos,ypos,zpos = tonumber(getElementData(v, "CRotationX")), tonumber(getElementData(v, "CRotationY")), tonumber(getElementData(v, "CRotationZ")) 
        local xlook,ylook,zlook = xpos - 300*math.sin(rotcam), ypos + 300*math.cos(rotcam), zpos 
        setPedLookAt (v, xlook, ylook, zlook, -1) 
    end 
end 
addEventHandler ("onClientRender", root, onClientLookAtRender) 

Then I tried with this other one but it doesnt work too:

Server:

function rotateHead() 
    for i,v in ipairs(getElementsByType("player")) do 
        triggerClientEvent("rotateHead", v) 
    end 
end 
setTimer(rotateHead, 3000, 0) 

Client:

addEvent("rotateHead", true) 
addEventHandler("rotateHead", root, 
function() 
    local rotcam = math.rad (360 - getPedCameraRotation (source)) 
    local xpos,ypos,zpos = getPedBonePosition (source, 8 ) 
    local xlook,ylook,zlook = xpos - 300*math.sin(rotcam), ypos + 300*math.cos(rotcam), zpos 
    setPedLookAt (source, xlook, ylook, zlook, -1) 
end) 

[IIYAMA]

send this information over from server to client:

https://wiki.multitheftauto.com/wiki/GetCameraMatrix

  
float targetX, float targetY, float targetZ 

[Sasu]

Something like this?:

Server:

function rotateHead() 
    for i,v in ipairs(getElementsByType("player")) do 
        local _,_,_, x,y,z = getCameraMatrix(v) 
        triggerClientEvent("rotateHead", v, x, y, z) 
    end 
end 
setTimer(rotateHead, 3000, 0) 

Client:

addEvent("rotateHead", true) 
addEventHandler("rotateHead", root, 
function(rx, ry, rz) 
    setPedLookAt (source, rx, ry, rz, -1) 
end) 

It says in debugscript 3: Bad Argument @ 'setPedLookAt'

[pa3ck]

You defined x, y, z not rx, ry, rz. You gotta correct that on the client side.

[Sasu]

It will not change anything because you can put everything you want as variable.

[xXMADEXx]

You need to trigger the client event for all of the players.

[WASSIm.]

addEventHandler("onClientRender", getRootElement(), function() 
  
for k,player in ipairs(getElementsByType("player")) do 
if getElementHealth(player) >= 1 then 
local width, height = guiGetScreenSize () 
local lx, ly, lz = getWorldFromScreenPosition ( width/2, height/2, 10 ) 
setPedLookAt(player, lx, ly, lz) 
end  
end 
    
end) 
  

[OGF]

Something like this?:

Server:

function rotateHead() 
    for i,v in ipairs(getElementsByType("player")) do 
        local _,_,_, x,y,z = getCameraMatrix(v) 
        triggerClientEvent("rotateHead", v, x, y, z) 
    end 
end 
setTimer(rotateHead, 3000, 0) 

Client:

addEvent("rotateHead", true) 
addEventHandler("rotateHead", root, 
function(rx, ry, rz) 
    setPedLookAt (source, rx, ry, rz, -1) 
end) 

It says in debugscript 3: Bad Argument @ 'setPedLookAt'

a Timer? are you crazy?

end)

What I mean is that you triggered ('rotateHead', v, x, y, z) then you wanted to set the ped looking at rx, ry, rz, which is not defined.

ignore pa3ck his post, it seems he doesn't know what the source is....

Btw try this: (not tested)

It will give you better information about the head rotation, the default update of the camera matrix is 4 secs.

addEvent("sendRotateHead",true) 
addEventHandler("sendRotateHead",root, 
function (xr,yr,zr) 
    if isElement(source) then -- make sure he is still in game 
        triggerClientEvent(root,"rotateHead",source,xr,yr,zr) 
    end 
end) 

  
  
  
  
local headUpdateFunction = function () 
    local x,y,z,xr,yr,zr = getCameraMatrix(localPlayer) 
    if xr and getElementHealth(localPlayer) > 0 then 
        triggerServerEvent("sendRotateHead", localPlayer, xr,yr,zr) 
    end 
end 
  
addEventHandler("onClientResourceStart",root, 
function () 
    setTimer(headUpdateFunction,1000,0) 
end) 
  
  
addEvent("rotateHead", true) 
addEventHandler("rotateHead", root, 
function(xr,yr,zr) 
    if isElement(source then -- make sure he is still in game 
        setPedLookAt (source, xr,yr,zr, 100) 
    end 
end) 

Updated.

[Desaster]

idk if I am late try this

function movePlayerHead() 
    for k, players in ipairs(getElementsByType("player")) do 
        if (getElementHealth(players) > 1) then 
            local w, h = guiGetScreenSize() 
            local lookatX, lookatY, lookatZ = getWorldFromScreenPosition(w/2, h/2, 10) 
            setPedLookAt(players, lookatX, lookatY, lookatZ) 
        end 
    end 
end  

lol after reading this topic I saw that I use the same as wasim's one

Updated.

Now, the character is looking at me(camera).

Something like this?:

Server:

function rotateHead() 
    for i,v in ipairs(getElementsByType("player")) do 
        local _,_,_, x,y,z = getCameraMatrix(v) 
        triggerClientEvent("rotateHead", v, x, y, z) 
    end 
end 
setTimer(rotateHead, 3000, 0) 

Client:

addEvent("rotateHead", true) 
addEventHandler("rotateHead", root, 
function(rx, ry, rz) 
    setPedLookAt (source, rx, ry, rz, -1) 
end) 

It says in debugscript 3: Bad Argument @ 'setPedLookAt'

a Timer? are you crazy?

Have you got any good idea?

[IIYAMA]

I will look at it tomorrow, probably because the camera end stops at the player.

It should be extended.

[Vinyard]

Any ideas? It's a bit late to ask, but who knows..

[IIYAMA]

Any ideas? It's a bit late to ask, but who knows..

Ah, you are hunting for free scripts...

I know because I already fixed it and shared it with the poster.

So yes a bit late,

So yes a bit late,

Could you give us some instructions on which functions are needed?

[IIYAMA]

For what I created:

"onClientResourceStart" 
"onClientRender" 
"onPlayerSpawn" 

triggerClientEvent 
table = {} 
getNetworkStats 
getDistanceBetweenPoints3D  
getTickCount 

and much more...

for a working a script, that's keeping up the performance of your internet speed.

At the moment I am busy with something similar to combination of slothbot and dayZ, I don't have time to guide you, sorry.

[pa3ck]

Mkaay, so it's not an easy thing, is it? Thanks anyways.
