how to set camera in the car?

Hey there,

I have a car that is moving,I want to set the camera in the cab,and follow the car.
I tried using ‘trackEntity’ ,but the perspective is outside the car.

And I found a demo：GEFS Online can achieve this effect

how can I do that?

Thanks,

-Zhang

You can use Camera.setView() along with a destination (where do you want the camera to be) and an orientation. The destination would just be the same as the car’s (maybe with a bit of an offset) and the orientation would also be the same as the car’s (although I found I needed to add PI/2 to the entity’s heading).

Try setting up an onTick() listener and updating the camera every clock tick. This creates a really smooth view.
