    if (Keyboard.GetState().IsKeyDown(Keys.Left)) player.rotation.Y += 0.1f;

    if (Keyboard.GetState().IsKeyDown(Keys.Right)) player.rotation.Y -= 0.1f;



    player.velocity *= 0.9f; // friction



    if (Keyboard.GetState().IsKeyDown(Keys.Up))

    {

       acceleration.X = (float)Math.Sin(player.rotation.Y) * 0.001f;

       acceleration.Z = (float)Math.Cos(player.rotation.Y) * 0.001f;

    }



    // camera follow

    gamecam.position = new Vector3(50, 50, 50) + player.position;

    gamecam.target = player.position;



    MovePlayer(dt);



    foreach (basicCuboid WallSegment in walls)

    {

        if (player.hitBox.Intersects(WallSegment.collisionbox))

        {

            ElasticCollision(WallSegment);

        }

    }

    if (player.hitBox.Intersects(door.collisionbox))

    {

        ElasticCollision(door);

    }



    if (player.hitBox.Intersects(TriggerBoxRockFall) && !rockFalling)

    {

        rockFalling = true;

        rock.velocity = new Vector3(0, 0.2f, 0);

    }



    if (rockFalling)

    {

        Vector3 gravity = new Vector3(0, -0.01f, 0);

    }

So this is the code I have so far, I am unsure about how to make the rock actually fall though. What am I missing or have I typed something in wrong? I need the rock to fall upon the player colliding with a trigger box below the rock.
