Vehicle aim

[Anubhav]

Is it possible to get vehicle's aim? I din't find any function, please help me to get the functions. I'm trying to create a image there, and I saw this in MTA Battlefield #1/2 server.

Thank you for helping!

I'd assume you should be able to calculate it using getVehicleTurretPosition perhaps?

createVehicle -- That for create vehicle 
createPed -- That for create driver 
setElementAlpha -- If you want hide driver 
warpPedIntoVehicle -- That for create warp driver into vehicle 
setPedAnalogControlState -- That for control vehicle

Sorry, you din't get what I meant. I meant to get where the vehicle is aiming to FIRE. Like hydra missile aiming.

and Dealman can you give me a small example of it? I'm bad at calculating things such as this, first time.

getVehicleTurretPosition has the following example:

local vehicles = getElementsByType ( "vehicle" ) 
-- Loop through the vehicle list 
for vehicleKey, vehicleValue in ipairs(vehicles) do 
    -- Get the vehicle's turret position 
    local x, y = getVehicleTurretPosition ( vehicleValue )  
    -- Convert the positions to degrees, as that's much more useful if you'd want to output it 
    x = math.deg ( x ) 
    y = math.deg ( y ) 
    -- Get the vehicle's name 
    local vehicleName = getVehicleName ( vehicleValue ) 
    -- Tell everyone in the F8 console the turret's position 
    outputConsole ( vehicleName .. "'s turret rotation: " .. x .. ", " .. y .. "." )     
end 

Once the script starts, it'll tell you the rotation of the turret ( the gun on a tank, etc ). However, this will give you errors if the vehicle isn't equipped with a turret.

I know, I tried doing that, din't work for me.

If I get it right, returned rotation of turret is relative to vehicle's rotation. So in order to get the target position, you would have to get the aiming vector from turret's rotation, combine it with turret's position using getVehicleComponentPosition and then transform the result into world coordinate system by multiplying it by vehicle's matrix (getElementMatrix).

[Anubhav]

What is the turrent component called? and what do you mean by aiming vector? and which matrix?

[Castillo]

It was either: "misc_a", "misc_d" or "misc_b".

[Anubhav]

And aiming vector + which vector? how will I know misc_a or misc_b or misc_d?

[Dealman]

misc_a = Turret (Mesh)

misb_b = Gun Mantlet (Mesh)

misc_c = Muzzle (Dummy)

[DiSaMe]

By 'aiming vector' I mean the vector pointing to direction where the turret is aiming. And I said which matrix exactly, vehicle's matrix.

[Anubhav]

Sorry for bumping, but still I don't get this aiming vector. How should I get it?

[Anubhav]

I did myself, using vehicle component position to getPedTargetEnd.

There must be right click and it shows perfect! Thanks everyone whoever helped me.
