[Help]NFS like camera style

[Xierra]

Hi guys!

I have a question.

Do you know most of the NFS games?

What I mean here is that when you steer left or right (x) and not up and down, the camera will always follows it.

On GTA SA, it doesn't. I already think this is possible in MTA, so I got to figure it out how...

I dunno how to start. Can you guys tell me how?

[karlis]

some simple trigonometry, and getting position of vehicle, and zrotation

--clientside
local enabled=false
function getPointFromDistanceRotation(x, y, dist, angle) --credits to robhol
local a = math.rad(90 - angle)
local dx = math.cos(a) * dist
local dy = math.sin(a) * dist
return x+dx, y+dy
end
 
addCommandHandler("nfscam",function()
if enabled then
removeEventHandler("onClientRender",getRootElement(),rendercam)
else
addEventHandler("onClientRender",getRootElement(),rendercam)
end
   enabled=not enabled
end)
 
function rendercam()
local x,y,z=getElementPosition(getPedOccupiedVehicle(getLocalPlayer()))
local _,_,rotz=getElementRotation(getPedOccupiedVehicle(getLocalPlayer()))
local x2,y2=getPointFromDistanceRotation(x, y, 15, rotz+180%360)
setCameraMatrix(x,y,z,x2,y2,z+6)
end

Ah, You put the camera on the cockpit!

Also, I don't want camera like that. Something that doesn't shake and doesn't remove the parts of the HUD.

[Xierra]

No answers?

You know, the camera is like in Magnetwheels resource, but what I want is only follows right and left not up and down.

[karlis]

hud is not removed, and thats also not cockpit, and add some math.round for camera position for camera shake terminating

[Dark Dragon]

i think this will give a similar effect:

-- client
addEventHandler("onClientPreRender",getRootElement(),
function()
setCameraTarget(getLocalPlayer())
end
)

[karlis]

Ye, very nice would be to check mouse and dont set target if mouse moving

[Xierra]

Yeah, I want that. Moving the camera by mouse means making the target to be removed, then after 3 seconds of letting it go, target it back again.

And dragon, where should I put that?

[Jason_Gregory]

In your Clientside Script, onClientRender is a Clientside Function only...

[karlis]

try this, heres included that 3sec timer

local lastMouseTick=0
local enabled=false
 
function mousemove()
  lastMouseTick=getTickCount()
end
 
function targetcam()
if getTickCount()-3000>lastMouseTick then
setCameraTarget(getLocalPlayer())
end
end
 
function enablecam()
if enabled then
removeEventHandler("onClientMouseMove",getRootElement(),mosuemove)
removeEventHandler("onClientPreRender",getRootElement(),targetcam)
else
addEventHandler("onClientMouseMove",getRootElement(),mosuemove)
addEventHandler("onClientPreRender",getRootElement(),targetcam)
end
  enabled=not enabled
end
 
addCommandHandler("nfscam",enablecam)
bindKey("N","up","nfscam")

note:im not sure do i need use onClientMouseMove or onClientCursorMove

[Xierra]

I got bad arguments on line 16 & 19 if I execute a command.

What about this, if the vehicle is only facing down, the camera follows it.

[karlis]

change mosuemove to mousemove
