PlayerMoveEvent and camera shake

Hello.

I want block player moving when some variable is true.

I'm using

Code:

    @EventHandler
    public void onMove(PlayerMoveEvent e) {
        if(e.getPlayer()!= null  ){
            if(x==true)
                  e.setCancelled(true);
          
          
        }
    }

This function block all events including camera move.
2.when i have moved my camera is shaking :0
How to unlock camera and dont shake it?

 

You could store the block that the player is in inside a variable then periodically check if they have moved out of that block, if they have then teleport the player back. That would give them full range of movement but without letting them leave the current block

 

You can teleport the player to the x, y, z they can from with the yaw and pitch they are going to. It's a bit juddery but you can still look around.

 

Why would the player ever be null? You don't need to check that.

 

Why don't you just check if the getFrom x y and z is not equal to the getTo x y and z?

Code:

            if (!e.getTo().equals(e.getFrom())){
                e.setCancelled(true);
            }

 

Code:

player.setWalkSpeed(0); //prevent player from walking.
player.setWalkSpeed((float) 0.2); //restore normal walk speed.
player.addPotionEffect(new PotionEffect(PotionEffectType.JUMP, 10000, 128)); //this will prevent player from jumping.

I think that method is a lot smoother

 

Code:java

if (e.getFrom().getPitch() == e.getTo().getPitch() && e.getFrom().getYaw() == e.getTo().getYaw()) {
p.teleport(e.getFrom());
//or this: (could by buggy)
e.setCancelled(true);
}
