unable send data controller javascript

so have few questions. first. javascript game code(graphic display in browser) wich time working. want calling controller , transfer data it. , receive data controller(physic engine). dont want reload of page controller action. second. idea making comunication controller in case?

it's fine use transfer data between client , controller without reloading page. i.e. using ajax , @responsebody tag in controller.

alternatively, can bypass controller altogether , go straight defined remote methods (e.g. in service layer) direct transfer of data using dwr (direct web remoting. direct transfer using ajax bypass mvc framework.
