Spectate on a vehicle/ped/object

orel56000 · September 27, 2017

Hi, someone knows how to spectate an object or a ped or a vehicle? SetCameraTarget can spectate only players and I saw server the made me spectate on a vehicle or a ped inside idk...

if someone knows how to do it please help...

any help will be welcome!

lol I needed the exact same thing just a few hours ago Have a look at my topic:

The functions which did it for me were:

GetCamera()

setElementPosition()

atachElements()

The code example at the first function's wiki is what we're looking for.

Thank you for reply.

I need that free camera movement too.. so it does not helped me too much but thanks anyway

I found a way for all who looking for that too

that the calculations:

local specdis, specon = 0, nil

function MoveMouse(rx, ry, x, y)
	if not isCursorShowing() then
		local sx, sy = guiGetScreenSize()
		AngX = (AngX + (x - (sx/2))/10) % 360
		AngZ = (AngZ + (y - (sy/2))/10) % 360
		if AngZ > 180 then
			if AngZ < 315 then AngZ = 315 end
		else
			if AngZ > 45 then AngZ = 45 end
		end
	end
end
function RenderVeiw()
	local ox, oy, oz
	local x, y, z = getElementPosition(specon)
	ox = x - math.sin(math.rad(AngX)) * specdis
	oy = y - math.cos(math.rad(AngX)) * specdis
	oz = z + math.tan(math.rad(AngZ)) * specdis
	setCameraMatrix(ox, oy, oz, x, y, z)
end

function PlayerSpecOnElement(spec, distance)
	if spec == nil or distance == nil or spec == "None" then
		specon = nil
		specdis = 0
		return 1
	end
	if specon then
		removeEventHandler("onClientRender", getRootElement(), RenderVeiw)
		removeEventHandler("onClientCursorMove", getRootElement(), MoveMouse)
	end
	specon = spec
	specdis = distance
	addEventHandler("onClientRender", getRootElement(), RenderVeiw)
	addEventHandler("onClientCursorMove", getRootElement(), MoveMouse)
end

addEvent("setPlayerSpecOnElement", true)
addEventHandler("setPlayerSpecOnElement", getRootElement(), PlayerSpecOnElement)

@orel56000 AngX and AngZ are not defined anywhere and give error. Can you give example on how to use these functions to set the camera on an object and make it move freely to look around that object via mouse move (just like it is in normal spectating).

oh sorry, that a fix:

that the calculations:

local AngX, AngZ, specdis, specon = 0, 0, 0, nil

function MoveMouse(rx, ry, x, y)
	if not isCursorShowing() then
		local sx, sy = guiGetScreenSize()
		AngX = (AngX + (x - (sx/2))/10) % 360
		AngZ = (AngZ + (y - (sy/2))/10) % 360
		if AngZ > 180 then
			if AngZ < 315 then AngZ = 315 end
		else
			if AngZ > 45 then AngZ = 45 end
		end
	end
end
function RenderVeiw()
	local ox, oy, oz
	local x, y, z = getElementPosition(specon)
	ox = x - math.sin(math.rad(AngX)) * specdis
	oy = y - math.cos(math.rad(AngX)) * specdis
	oz = z + math.tan(math.rad(AngZ)) * specdis
	setCameraMatrix(ox, oy, oz, x, y, z)
end

function PlayerSpecOnElement(spec, distance)
	if spec == nil or distance == nil or spec == "None" then
		specon = nil
		specdis = 0
		return 1
	end
	if specon then
		removeEventHandler("onClientRender", getRootElement(), RenderVeiw)
		removeEventHandler("onClientCursorMove", getRootElement(), MoveMouse)
	end
	specon = spec
	specdis = distance
	addEventHandler("onClientRender", getRootElement(), RenderVeiw)
	addEventHandler("onClientCursorMove", getRootElement(), MoveMouse)
end

addEvent("setPlayerSpecOnElement", true)
addEventHandler("setPlayerSpecOnElement", getRootElement(), PlayerSpecOnElement)

put that on client side

If you wanna use it on clientside:

PlayerSpecOnElement(element, lookDistance)

if you wanna use it on serverside:

triggerClientEvent(player, "setPlayerSpecOnElement", getRootElement(), element, lookDistance)

sorry for posting again i coulden't edit my reply

And the distance is how far you see around the object, right?

No, to disable it just write "None" instend of the arguments

ex.

on server side:

triggerClientEvent(player, "setPlayerSpecOnElement", getRootElement(), "None")

koragg · September 28, 2017

Nice, works like a charm. But is there a way to keep the focus of the camera behind the object when I'm not moving my mouse? I mean, when the object I'm spectating (a ghost car) makes a turn the camera stays at the same spot at which I left it via my mouse. I need it to go behind the object (ghost car) after a few seconds of not moving my mouse. Hope you can help!

OK, it works almost perfect. But do any of you know if there is a way to know when the camera has stopped moving itself and it's at the back of the target? What I mean is this:

After not moving my mouse for some seconds the camera goes behind the object automatically. Can I somehow know when the animation of it going to the back has ended? I hope you understood me I need to know when the animation of the camera going to the object's rear has ended because I want to force it to stay behind the object then (if mouse is not moved). @orel56000 @idan1432

It didn't work at first but when I removed the 'ticks2' variable it worked fine. All I needed was "if dis1 < speed then". Now I'll try to set the camera's Z position according to the car's rear position. Currently it keeps the same Z position even if car goes down a hill for example (isn't pointing directly at it's back, but is below the gta textures sometimes). Hope I can do that alone , if not I'll reply here again. Thank you for everything!

koragg · October 1, 2017

Don't even have slightest idea how to do this, maybe some hint?

Here's an updated code if anyone needs it. With it you can use Q and E (and both) just like in normal spectating. Q - look left of vehicle, E - look right of vehicle and Q+E - look infront of vehicle:

But I still can't figure out how to automatically fix the Z position of the camera If you know the maths behind it (you knew how to fix the X position to always be at the car's back) I'd be grateful if you tell me how to achieve this as well The camera just stays at one Z position, even if the vehicle is going up or down a hill and it looks bad. Need it to always stay behind the car just like it does on a normal straight road.

Still can't find a way to fix the camera's Z position to be like in normal spectating mode - always behind the car, not under or ontop of it.

koragg · October 10, 2017

Here's a video explaining the problem better:

As you see in the first 50 seconds of the video the camera is behind the car. But from around 0:55 when the car goes up the hill the camera does not stay behind it but goes ontop of it.Also on 1:05 you can clearly see how the camera goes under the GTA textures because it does not stay behind the car, but this time is under it as it's going downhill. Could somebody please help me out with a code or formula so that the camera will stay always behind the car, thus avoiding those under-texture peaks and ontop-of-car weird look. It should always be focused at the back of the car as it is on a straight road from the start of the video until around 0:50. This is the full code for the camera function:

local AngX, AngZ, specDist, specTarget, ticks, speed, fixedCam, isMinimized = 0, 0, 0, nil, 0, 0.8, true, false

omg, why don't you just use setCameraTarget?

edit: ok, I see, it is only for players.

As for your problem:

- use attachElements instead of setMatrix (it won't shake)

- to sovle camera rotation, usssh.... it requires quite harsh 3D Vector manipulations. You have to use Vector to keep camera position relative to vehicle, then rotate it on mouse movement and transform from global coordinates to vehicle local coordinates, meanwhile moving it back to target position (which has to be updated with vehicle x rotation) when no mouse movement happens. I made custom camera this way for my project, but it uses modified vectors, so I don't really know any easy way to help you.

At first I did it with attachElements but the camera couldn't be moved by mouse then. Anyway, the shake is from the race_ghost resource, it lags even when not spectating it . Can you have a look at the code I posted and see how the X position is fixed? I think @orel56000 fixed it.(OK, it was @idan1432) Maybe something similar for the Z one (though I tried and meh)? Problem's that I'm not that good at maths stuff (like Vectors, etc) otherwise I'd do it myself but can't do anything with such calculations And if not, thanks for trying atleast

Sadly it didn't. But I noticed that you tried to fix it only by using 'AngZ'. Isn't the 'AngZ' variable used while moving mouse? The problem in video is that without moving mouse, the camera does not go up/down a bit so that those glitches can be avoided.

Spectate on a vehicle/ped/object
