Speichern des Rückgabewerts einer Zufallszahl als lokale Variable?

Question

Also praktiziere ich grundlegendes Java, indem ich einen Pokemon-Kampfsimulator (mit JOption Panes) erstelle.

Ich benutze die folgende Methode, um den Angriffswert des Pokémon als Maximum zu nehmen, und setze zur Vereinfachung einen Wert von 0 ein.

public static int randomDamage(int min, int max) { 
    int range = (max - min) + 1; 
    int randomDamage = (int)(Math.random() * range) + min; 
    return randomDamage; 

Hier ist, wo ich die Methode aufgerufen habe.

public static void battle(Pokemon pokemon1, Pokemon pokemon2) { 
    showMessageDialog(null, pokemon2.name + "'s stats are: \n Health: " 
      + pokemon2.health + "\n Attack: " + pokemon2.attack + "\n Speed: " + pokemon2.speed); 
    showMessageDialog(null, pokemon1.name + " begins the fight against " + pokemon2.name); 
    do { 

     if (pokemon1.health > 0 && pokemon2.health > 0) { 
      showMessageDialog(null, pokemon1.name + " attacks " + pokemon2.name); 
      pokemon2.health = pokemon2.health - randomDamage(0,pokemon1.attack); 
      showMessageDialog(null, pokemon1.name + " does " + pokemon1.randomDamage + " damage to " + 
        pokemon2.name + " and " + pokemon2.name + " has " + pokemon2.health + " left."); 
     } 

     if (pokemon1.health > 0 && pokemon2.health > 0) { 
      showMessageDialog(null, pokemon2.name + " attacks " + pokemon1.name); 
      pokemon1.health = pokemon1.health - pokemon2.attack; 
      showMessageDialog(null, pokemon2.name + " does " + pokemon2.attack + " damage to " + 
        pokemon1.name + " and " + pokemon1.name + " has " + pokemon1.health + " left."); 
     } 


    } while (pokemon1.health > 0 && pokemon2.health > 0); 
    if (pokemon1.health < 1) showMessageDialog(null, pokemon1.name + " has been reduced to 0 health. " 
      + pokemon1.name + " has lost the fight."); 
    else showMessageDialog(null, pokemon2.name + " has been reduced to 0 health. " 
      + pokemon2.name + " has lost the fight."); 

} 

Das scheint Schaden randomisiert zu werden, wie ich erwartet hatte, aber es wird immer sagen: „Charmander tut 0 Schaden Rattata und Rattata hat x Gesundheit links“.

Ist es möglich, den RandomDamage-Wert von der Gesundheit zu subtrahieren und diesen Wert dann in meinem JOption-Fenster anzuzeigen?

Vielen Dank!

Sie müssen zuerst den Rückgabewert randomDamage (d. H. In pokemonX.randomDamage) speichern, wenn Sie ihn mehrmals verwenden möchten.

Beispiel (unter der Annahme Pokemon s hat ein int randomDamage Mitglied):

pokemon1.randomDamage = randomDamage(0,pokemon1.attack); 
pokemon2.health = pokemon2.health - pokemon1.randomDamage; 
showMessageDialog(null, pokemon1.name + " does " + pokemon1.randomDamage + " damage to " + pokemon2.name + " and " + pokemon2.name + " has " + pokemon2.health + " left.");
