I am stuck on the part when you fight darth vadet and I can't get past..

In the beginning of the battle keep your distance and wait for him to throw his lightsabor then block the sabor he should be vulnerable for a few seconds(tip don't force dash into him that effect won't work on vador) after that when the starkiller clones appear use the mind trick on as many starkiller clones as possible (it is tempting to kill them but you need them to stop vador)(when you have controlled as many as you could sit back and watch them try and fail to stop vador) then when vador has either killed them or they timed out return to your basic beginning strategy then when vaador kills one by choking him then throwing him into that object now mostly a ball of electricity when vador is throw him into it throw your lightsabors at the ball of electricity then hurry up and get him (he is now more vulnerable and will stay that way for a little bit longer but still not forever force dash is still ineffective) and that electricity ball will appear again but you either have to wait for it to appear again or you could return to your beginning strategy
