"Can't invoke" help

Hey everyone,

I have a question. It might sound a bit nooby, but I'm trying to expand my knowledge on for loops.
I am having this bug.
I have this here:

Code:

Player[] onlinePlayers1 = Bukkit.getOnlinePlayers().toArray(new Player[Bukkit.getOnlinePlayers().size()]); {
                     Player[] player = onlinePlayers1;

No errors there. However when I use "player" I get errors.
For example at "player.getName()" it says
"Cannot invoke getName() on the array type Player[]"

At "player.hasPermission()"
it says
"Cannot invoke hasPermission(String) on the array type Player[]"

How can I go about fixing this? Sorry if this sounds a big nooby

@glasseater You are trying to invoke the method on the Array object itself. Anyways what's the point of your code? I am positive there is a better way to achieve what you are trying to do.

 

@teej107
I'm setting a players particle effect inside a runnable. Please let me know if there is a better way to do this! I'm sorry I do not really understand how to make it so it doesn't invoke on the array?

 

@glasseater https://docs.oracle.com/javase/tutorial/java/nutsandbolts/arrays.html.

Setting a player's particle effect or every player's particle effect? I can assure you that you do not need an Array for either.

 

@teej107
Just setting one players particle, but for everyone on the server to see.

 

I still don't quite understand. Are you having particles only on one player? Perhaps you should post what you have tried first. Or attempt something if nothing was attempted yet.

 

@teej107
Yes only on the player who selects the particle effect.

Heres what I have tried.

Code:

        Bukkit.getScheduler().scheduleSyncRepeatingTask(this, new Runnable() {
            double i = 0.0;
            double newY;
         
            @Override
            public void run() {

                final double slice = 6.283185307179586 / points;
                final double slice2 = 6.283185307179586 / (points * 2.5);
Player[] onlinePlayers1 = Bukkit.getOnlinePlayers().toArray(new Player[Bukkit.getOnlinePlayers().size()]);                     Player[] player = onlinePlayers1;
                    final Player player = onlinePlayers1;
                    if (Particle.this.LavaPopperz.contains(player.getName()) && player.hasPermission("particle.lavapop")) {

 

@glasseater
You should probably learn how arrays and variables work in Java first.
1. You have two variables of the same name.
2. An array of players cannot be a player. They are different types.

@rbrick
I posted the wrong bit of code that's my fault. This still may be wrong but is it for the same reason?

Code:

 Player[] onlinePlayers = Bukkit.getOnlinePlayers().toArray(new Player[Bukkit.getOnlinePlayers().size()]); {
     Player[] p = onlinePlayers;
//Other code here
            

 

I don't quite understand what you are trying to do, but I'll try to help out.

1. The method
   Code:

   Bukkit.getOnlinePlayers()

   returns a collection of Player objects, which you do not need to turn them into an array. Simply use the the methods provided by the Collection.
2. You are assigning a variable to another variable, which is redundant. I guess you are trying to find a particular player from the server ?
3. If you are simply playing particle effects on a player, it should be played to the nearby players too. There is not a need for you to handle the visibility of the particles.

 

@Chloe-chan
But then how would I define p/player? Because now im using Player[] player = onlinePlayers (which if I um understand correctly, thats where I am wrong. If I am correct with that bing wrong, how would I define the player?

 

for (Player p : Bukkit.getOnlinePlayers)

 

Are you trying to find a particular player?
If so, you can try

Code:

Bukkit.getPlayer("Notch");

to get the player with name "Notch". NOTE: It is recommended to use UUID instead of player name.



Are you trying to loop every player online ?
