Hello :) I need help with my project .-. im trying to build something like moba+tower defense but i have problem how to call / get hp from another class, so each class have its own hp, and damage i tried this before just example Minion1 class public int hp = 300; public int damage = 25; Hero1.class //i need help here , how to call that public int hp and damage .-. i dont quite understand in there, Thx a lot before, and sorry for my english ._. im still trying to learn it >.<

It is not the class that has the int values -- it is the objects (minion objects) created from that class that each has an 'hp' and 'damage' value. So, you need a reference to a particular minion. So, the question is, which minion are you trying to acquire the values from?

You usually wouldn't 'call' these ints. You would call a method on the enemy to damage it when attacking. 
//in Hero1's act method
Minion1 minion = (Minion1) getOneIntersectingObject(Minion1.class);
if (minion != null)
{
    minion.loseLife(damage); //damage should be the damage of the Hero
}
//in Minion1
public void loseLife(int dmg)
{
    hp -= dmg;
    if (hp <= 0)
    {
        getWorld().removeObject(this);
    }
}
The minion can itself have the same code to damage the Hero or the Hero could get the damage of the minion and deals it to itself.

Remember: a class is not the same as an object. Line 7 calls the method on the minion object which is touching the hero.

so something like this? 1.Minion1 have a public void loseLife(int dmg) >>then 2.The hero call minion1 method in minion.loseLife(damage)

Yes I was hoping that line 1 in both code snippets would make that clear.

Show how you tried to implement it. What does "doesn't work" mean: Does it compile? What is happening?

it compile, but the minion immediately got removed after intersecting .-. i tried to put int hp as 300, so if it intersecting, hp will be reduced by 35 but not working xD

for hero class public void minion() { Minion1 minion = (Minion1) getOneIntersectingObject(Minion1.class); if (minion!= null) { minion.kurangHp(35); } } for minion class int hp = 300; public void kurangHp(int dmg)//i tried to change the int with number, not working .-. { hp -= dmg; if (hp <= 0) { getWorld().removeObject(this); } }

Right now, the minion will die after the 9th hit of the Hero. (Which will happen if the intersection lasts about a 6th of a second.) If you change 35 to 1, it will take about 5 seconds. If you want the hero to deal damage just every two seconds (for example) or you only want him to do damage when the intersection "starts" and not as long as he intersects, you have to change the code to your needs.
