Need Help with percentual math!

Hello!

I'm currently working on a Custom Battle System.

Every Mob has a maximum health. For our example, it's 5.

Then, every mob has a current health, which is also stored in a HashMap.

I want to display the left health of the mob using the players' hearts. So I'm using the following code:

Code:java

 p.sendMessage("Current Lifes:" + MonsterLifes.get(l));
p.sendMessage("Maximum Lifes:" + MaximumMonsterlifes.get(l.getCustomName()).toString());
double PlayerHealth = MonsterLifes.get(l) / MaximumMonsterlifes.get(l.getCustomName()) * 20;
p.sendMessage(PlayerHealth + " left.");

And the Output is the following (I'm using a weapon that deals 2 damage) after 2 hits:

Current Lifes: 3
Maximum Lifes: 5
0.0 left.

Current Lifes: 1
Maximum Lifes: 5
0.0 left.

The thing that is confusing me right now: Why the hell is the quotient of Monsterlifes divided by MaximumMonsterLifes always 0.0? How can I fix this?

 

int / int results in int.
Cast one of these to double first.

 

Gabum I'm just wondering why you would need to divide the two variables...
Wouldn't you just subtract the current from the maximum?

I need to get the percentual value of the both, which I then multiplied by twenty to get the health I need to fill in.

Thank you very much, that helped!

 

Gabum This is not the inexperienced Bukkit Developer you're looking for... *shifty eyes*

 

What?
