Doing something when a players health is at a certain amount

The Title says it all, when a players health is a at certain amount, let's say half a heart, for example it would say something to the player, how would I go about getting the players health?

Thanks.

 

Player#getHealth()

 

if (player.getHealth() == (insert number)) {
DoSomething

}

@SuperOriginal ?

 

Yes,
20.0 = 10 Hearts
1.0 = Half a heart
ect

 

@Phishy Make sure you aren't using CraftBukkit. #getHealth() is ambiguous in CraftBukkit.

 

Wrong.
Player has 20 half hearts.
10.0 = 10 full hearts
1.0 = 1 full heart
0.5 = 1 half heart

It is possible:

Code:java

((Damageable)player).getHealth()

 

I'll try it out.

Edit: I've tried that, here is the code

if(((Damageable)player).getHealth() == 10.0) {
event.setCancelled(true);

}

Doesn't seem to be working. Am I doing something wrong?

 

That makes no sense what so ever.
Must I draw you a picture? A player has 10 hearts (ingame). #getHealth and #setHealth returns a double. 1.0 is half a heart. 5.0 is 2 and a half hearts ingame. 10.0 is 5 hearts ingame. 20.0 is 10 hearts ingame. Please, check your math before you post.

While you could do:

Code:

((Damageable)player).getHealth();

It is recommended you just use Bukkit instead.

@Phishy Please post the full code. I'm not sure what event you're using.

 

@CodePlaysMinecraft is this right?

if(player.getHealth() == 10.0) {
event.setCancelled(true);

}

 

@Phishy

 

@EventHandler
public void JesusPlayers(EntityDamageEvent event)
{
if(event.getEntity() instanceof Player){
Player player = (Player) event.getEntity();
if(Jesus.jesusplayers.contains(player.getName())) {
if(player.getHealth() == 10.0) {
event.setCancelled(true);

}
}
}
}

 

@Phishy No, it's not because doubles are doubles, and floating point stuff it's weird as hell.

In any case you want to directly compare you should cast it to integer, otherwise you need to remember that 10.0000001 is not 9.999999

 

So I should do...?

 

@Phishy Cast it to integer or don't directly compare but use 'less than' and 'more than' comparision?

 

Did you even bother checking to make sure you were correct?
