[HELP] Camera rocket script!

[AlvarO]

Hello guys, yesterday i was creating a script, a car who launch rockets, but i got a question...

How can I put for that when you launch a rocket (for example a grenade) it goes for where you are looking with the screen? I dont know if I explained good because my english is a pretty shit.

There you have the code:

function shootProjectile() 
    local vehicle = getPedOccupiedVehicle(localPlayer) 
    if(vehicle)then 
        local x, y, z = getElementPosition(vehicle) 
        createProjectile(vehicle, 19, x, y, z) 
        else 
        outputChatBox("No estas dentro de un vehiculo",255, 0, 0) 
    end 
end 
bindKey("k", "down", shootProjectile)

try

local x, y, z = getElementPosition(localPlayer) 

instead of

local x, y, z = getElementPosition(vehicle)

Is the same, make the same function but what I want is launch the rocket where the camera is looking.

I don't know but I think I've to use:

setCameraMatrix 

[Mr.unpredictable.]

You want to aim where your car is facing?

[AlvarO]

No, see, I want the missile looking out to where the screen, for example the car is looking at a building and I'm looking to the right, so I want that the missile will be launched to the right.

I guess you will then have to use getCameraMatrix and its facing integers together with few arithmetic operations.

[AlvarO]

Then how it will looks like? The script I mean

[Mr.unpredictable.]

use these functions

  
getCameraMatrix  
getElementPosition 
getElementMatrix 
getElementRotation
