How can I push a player forward?

I want to push a player forward, but I dont now how?

 

You can use setMotion to push a player foward

PHP:

$player->setMotion(new Vector3());

 

Yes I know but how?

 

PHP:

$player->setMotion($player->getDirectionVector()->multiply(2));//set 2 to whatever amount of force you want to apply to the player

 

Thanks

 

I want to push the player and make them go up at the same time, how would you do that?

 

Set the motion's y to a positive value
