I think you may need to use "Rubber Duck Debugging". You are casting the Entities last damage cause to an Event

This is repeated multiple times. Move this out of the if statement.

Have you debugged? What lines deal with the player's score?

 

51 to 55
78 to 102

 

Here is your problem. You are looping through all player's online and you are setting everyone's score to be what is in the map.

 

@Zombie_Striker

Yeah I know, but the point is: I have no idea of how to set individual scores... Like... How can I look for players in a certain world then set a world scoreboard with individual scores?

 

@Swakiny
You cann loop through all the players online by using Bukkit.getOnlinePlayers(). This will only return the players, so there are less objects to loop through.

To make sure it is specific to a player, check if the player is the damager. If it is, set his score.

 

@Zombie_Strike

How it looks?

Code:

if(dmge.getDamager() instanceof Player)
                {

@Swakiny
You test if the damager is a player, and then you test if the damager is a player. Shouldn't the one if statement be enough?

Does it work? Have you tried it yet?

 

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/Entity.html#getLastDamageCause()

 

I don't know why, but if I don't check 2 times I get error... I'll see if I can check only 1 time... But it's working...

@Zombie_Striker

By the way, about casting last damage cause to an event, then i just need to...
EntityDamageByEntityEvent xxc = (EntityDamageByEntityEvent)dg;
insteadof
EntityDamageByEntityEvent xxc = (EntityDamageByEntityEvent)dg.getLastDamageCause();??

About one statement I get it to work, wasn't working because I was casting Player player = (Player) dmge.getDamager(); BEFORE veryfing if the damager is a player. LOL

Now I think everything is working fine...

@Swakiny
You may be getting the error if the if "dme" or the damager is null. Check if those two objects are null before creating the player instance.

 

If i remove dg.GetLastDemageCause i get error...

Line 365
EntityDamageByEntityEvent xxc = (EntityDamageByEntityEvent)dg.getLastDamageCause();

 

Yeah but if I don't cast Entities last damage cause to an Event I get error. If I do, everything works fine...

 

@Swakiny
That's not the type of logic you should use. Think about it. You have to make an entity and event to check if it's an entity. In what world does that make sense?

I think what you're looking for is this :
https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/Entity.html#getLastDamageCause()
Using this, you can get the last damager. Use EntitygetLastDamageCause#getDamager to return the damager.

 

oh. Now I got it. Let me try.

@Zombie_Striker

So... like this?

Entity xxc = (Entity) (((EntityDamageByEntityEvent) dg.getLastDamageCause()).getDamager());
