Solved Health Change (Event?)

How would I go about event that gets called when player's health changes. Including damage, regen or set via another plugin. I have searched the javadocs but haven't found any events like that.
If there's no event, would there be any way to call code when player's health changes?

Regen - EntityRegainHealthEvent
Damage - EntityDamageEvent

For the last one, I'm not sure. I don't think there is a way, you'd probably have to create a custom event.

 

MrSparkzz
Will those event get called with beacon/potions as well?

 

deathknife
With the beacon it will, potions... I'm not sure. But try it, if it doesn't work, you could always create an on right click event with the throwable potions an have the event set to cancelled. And for the drinkables, I'm not sure how you'd do that.

 

MrSparkzz
Done some testing and it seems that beacon and potions do call regen event.
Now I'm wondering, if there would be any way to detect change when plugin uses .setHealth();

 

deathknife
I'm not sure on how to do that, I mean the only way I could think of is to create a custom event that checks a players health every second or so, then if it isn't equal to what it was, set it back to what it was. But I'm sure that would cause a lot of lag. Good Luck!

 

MrSparkzz
Alright. Thank you, that shouldn't be a big of a problem though. But I came across a problem with those events, when I get player's health in any of those events, it gets the health they had before it regened/damaged.

 

deathknife
show me your events?

 

Code:java

public class CookiesListener implements Listener {
 
 
 
@EventHandler
public void onHeal (EntityRegainHealthEvent event) {
if(!(event.getEntity() instanceof Player)) {
return;
}
Player player = (Player) event.getEntity();
 
Damageable damag = player;
double health = damag.getHealth();
player.sendMessage("HP:" + health);
 
}
 
@EventHandler
public void onDamage (EntityDamageEvent event) {
if(!(event.getEntity() instanceof Player)) {
return;
}
 
 
Player player = (Player) event.getEntity();
 
Damageable damag = player;
double health = damag.getHealth();
player.sendMessage("HP:" + health);
 
}
}

If I have 20 health, and jump off a cliff and take damage, it shows 20.0, but I do get damaged. For regen the same. For example, i have 10 hearts and regen 1 heart. It will say 10 instead of 11.

add this

Code:java

 
event.setCancelled(); // you might need to put `true` in the parentesis
 

under this

Code:java

 
if(!(event.getEntity() instanceof Player)) {
    return;
}
 

that will stop the player from receiving damage or health. Also, you can make that instanceof if statement into a simple if statement, like this

Code:java

 
if (!(event.getEntity() instanceof Player)) return;
 

 

MrSparkzz
I don't want to cancel that event, I want to get player's health (when they regen/dmg), but it gets the health they had before they regened/dmged.
For example, if player has 20 health and gets damaged 1 HP, It returns his HP as 20 instead of 19.

 

deathknife
Ohhh, I thought you wanted it not to damage/heal you. Well hmm... this should work, but I'm not sure if it takes armor and potion effects into account.

Code:java

 
Player player = (Player) event.getEntity();
 
double health = player.getHealth - event.getDamage();
 
player.sendMessage("HP:" + health);
 

 

MrSparkzz
That works great! used event.getAmount() for regen. All works perfectly now! Thank you!

if all is well and done, please set this thread to solved.
