Calculating coordinates behind a vehicle.

[roaddog]

As the title said, how to calculate the world coordinates of the behind of vehicle?

Like this:

I tried the getVehicleComponentPosition but getting confused because of this vehicle component

You can use getElementPosition and getElementRotation, e.g. if you are facing north then -5 in the y of your current position, if you facing south then +5, but you need to find out the trigonometry formula determine how much you add or subtract on the y or x axis. Btw why you need this?

If it's client-side you can calculate it using getElementMatrix, there's an example on wiki that's exactly what you need.

More specifically, you'll want to use this example;

function getPositionFromElementOffset(element,offX,offY,offZ) 
    local m = getElementMatrix ( element )  -- Get the matrix 
    local x = offX * m[1][1] + offY * m[2][1] + offZ * m[3][1] + m[4][1]  -- Apply transform 
    local y = offX * m[1][2] + offY * m[2][2] + offZ * m[3][2] + m[4][2] 
    local z = offX * m[1][3] + offY * m[2][3] + offZ * m[3][3] + m[4][3] 
    return x, y, z                               -- Return the transformed point 
end 

To get the co-ordinates behind the vehicle, simply do something like this;

local vX, vY, vZ = getPositionFromElementOffset(0, -1, 0)

Ah, after reading over and over again, I have understood now. Thanks for helping me out.
