Development Assistance Error, Eclipse is suggesting me to "Rename in file"

Hello, there! Here is my code.

Code:

    @EventHandler
    public void onSneakEvent(PlayerToggleSneakEvent event) {
        Player p = event.getPlayer();
        if (p.isSneaking()) {
            p.addPotionEffect(PotionEffectType.INVISIBILITY, 1, 0);
        }
        else if (p.isSneaking()) {
            p.removePotionEffect(PotionEffectType.INVISIBILITY);
        }
    }

I only have one error, and it's on this line:

Code:

p.addPotionEffect(PotionEffectType.INVISIBILITY, 1, 0);

It's underlining addPotionEffect in red, and Eclipse is telling me to "rename in file". What does this mean?

P.S. I'm a noob, so there may be other things not working properly. This error may be the only one Eclipse is giving me, but everything else still might not work.

Thanks!

There is not a method defined to take in what you just supplied as parameters. The parameter required is PotionEffect. You insert your three parameters into the constructor of PotionEffect when you are creating the PotionEffect object. (Which you pass into addPotionEffect)

 

@Gater12
So, I would replace PotionEffectType with PotionEffect?

 

@MaskedPigman

Code:

p.addPotionEffect(new PotionEffect(PotionEffectType.INVISIBILITY, 1, 0));

Thank you! Eclipse is no longer giving me any errors, but when I sneak, I don't turn invisible. My plugin.yml has no problems, and I made sure I saved the code.

 

@MaskedPigman In pseudo code, here's what you're saying.

Code:

if the player is sneaking
   give them invisibility
or else if the player is sneaking
   remove the invisibility

I think there's a '!' that you're missing before the argument to the second if.
Also, have you written in your onEnable()

Code:

getServer().getPluginManager().registerEvents(listener, plugin);
