how can i stop player if they move by a certain blocks

Location loc = player.getLocation();
Vector unitVector = new Vector(player.getLocation().getDirection().getX(), player.getLocation().getDirection().getY(), player.getLocation().getDirection().getZ());
unitVector = unitVector.normalize();player.setVelocity(unitVector.multiply(tmp));
if(player.getLocation().distance(loc)>(move_d)-1.0){
Vector zero_vec = new Vector(0,0,0);player.setVelocity(zero_vec);
}

code is like this.. but it didn't work
move_d and tmp is parameter
how can i fix it?

 

You need to handle PlayerMoveEvent and cancel it.

 

I want to push the player out at a certain speed by a certain block with command.
should i handle playerMoveEvent to do so?

 

@Gyul you said you wanted to stop a player from moving in the title. Moving a player at a different speed is a different story and one with which i have no experience.

 

@Gyul Can you explain what you want to happen in more detail?
