How do I detect if a Players score equals to 1

public final class Abilities extends JavaPlugin implements Listener {

@Overridepublic void onEnable() {
getServer().getPluginManager().registerEvents(this,this);}
@EventHandlerpublic void when(PlayerJoinEvent event) {
event.setJoinMessage("l,");}
@EventHandlerpublic void onMove(PlayerMoveEvent e) {
Player p = e.getPlayer();Scoreboard board = p.getScoreboard();Objective obj = board.getObjective("dash");Location loc = p.getLocation();Vector vector = loc.getDirection();Score score = obj.getScore("p"); if (score.equals(1)) {
p.setVelocity(vector.multiply(3));}
}
}

 

A request for help
sorry I Forgot to type ? and sorry if not giving enough info
this is my first time trying to make a plugin and i'm trying to edit the player velocity when the score of the player in the scoreboard named "dash" is 1
the velocity does work I just don't really know how to make the scoreboard or if the equals is actually the problem

 

thanks but can I multiply Vector Y or Vector X or do I just use setX
and how do I close a thread or does it close automatically

 

im asking if I can multiply Vector Y separately then the entire Vector

 

I meant than my bad
