WantsToViewVehicle how to use?

I have a problem with WantsToViewVehicle function.

My code changes only the type of camera, but not the player.
This is my code:
i call the function with in UpdateScoring:

Code:

CameraControlInfoV01 a;
                a.mID = vinfo.mID;
                a.mCameraType = 4;
                int uu = WantsToViewVehicle(a);

Code:

unsigned char ExampleInternalsPlugin::WantsToViewVehicle(CameraControlInfoV01& camControl)
{
    
    if (camControl.mID == -1) {
        return(false);
    }
    else {

       /* long id = camControl.mID;
        long cam = camControl.mCameraType;
        camControl.mID = id;
        camControl.mCameraType = 0;*/
        return (true);
    }
    
    
}

 

I'm slightly confused, why do you have code calling WantsToViewVehicle() ? The game will call that function, and it's up to you to decide if you want to do something, set the incoming .mID and mCameraType, and return true (or return false if you don't want to change anything).
