Controlling livingentity did not work

I am trying moving a sheep with nms, but there's a big problem.
see here.

Code:java

 
@EventHandler
void ontar(EntityTargetEvent event){
event.setCancelled(true);
}
 
@EventHandler
void ontar2(EntityTargetLivingEntityEvent event){
event.setCancelled(true);
}
 
@EventHandler
void oni(PlayerInteractEntityEvent event) {
if (event.getRightClicked() instanceof LivingEntity) {
LivingEntity le = (LivingEntity) event.getRightClicked();
CraftLivingEntity l = (CraftLivingEntity) le;
EntityInsentient en = (EntityInsentient) l.getHandle();
Navigation na = en.getNavigation();
na.a(0, 0, 10.0, .5);
System.out.print("test");
}
}

No err prints.The screen can print "test",but the sheep did’t move.
PS.The server is running on spigot


Yeah,the question has been solved,The reason is "na.a(0, 0, 10.0, .5);"
This location should be the player's location.
