Projectile direction problem


Recommended Posts

Hi all!

I'm trying to do a shooter script but I have a problem with the projectile direction:


function ejectProjectile() 
    local localVehicle = getPedOccupiedVehicle(source) 
    local ax, ay, az = getElementPosition(source) 
    local x,y,z = getPositionFromElementOffset(localVehicle,0,5,0) 
    local _, _, rz = getElementRotation(localVehicle) 
    local vx, vy = x - ax, y - ay 
    createProjectile(source, 19, x, y, z, 100, nil, 0, 0, 180 - rz, vx/3, vy/3, 0) -- I take velocity math here: viewtopic.php?p=357503#p357503 

The problem is that the projectile goes right(red arrow) and not straight(blue arrow) where it should go. I'm not good in math so if anybody can help me I will be very grateful :roll:. Thank you very much.

You can just do this and it will automatically shoot forwards, and it wont collide with your vehicle either.

function ejectProjectile() 
    local vehicle = getPedOccupiedVehicle(source) 
        local x, y, z = getElementPosition(vehicle) 
        createProjectile(vehicle, 19, x, y, z) 

I edited the wiki page for createProjectile for others that need it as well.
