我想在java中放一個小遊戲的概念，並遇到了一個奇怪的問題; int數組似乎沒有在我的代碼的某些部分存儲任何值！
（使用netbeans 8.2）
我懷疑這是一些小而乏味的事情，我錯過了。
這是一個基本生物的構造函數。看到「addTrait」方法？這是重點。試圖調試int數組
public Creature(String inputname)
{
if(DEBUG>0){System.out.println("DEBUG: CREATURE ");}
creaturename = inputname;
size = 1;
population = 1;
addTrait(new Trait("TEST",0,new int[]{4,4,4,4,4,4}),0);
addTrait(new Trait("EMPTY",0,new int[]{0,0,0,0,0,0}),1);
addTrait(new Trait("EMPTY",0,new int[]{0,0,0,0,0,0}),2);
}
這是在生物類中的方法。
public void addTrait(Trait newtrait, int slotnum)
{
myTraits[slotnum] = newtrait;
if(DEBUG>0){System.out.println("DEBUG: CREATURE > "
+ "addTrait > myTraits["+slotnum+"].getName() = "+
myTraits[slotnum].getName());}
for(int k=0;6>k;k++)
{
System.out.println("DEBUG: CREATURE > "
+ "addTrait > myTraits["+slotnum+"].getEffects()["+k+"] = "+
myTraits[slotnum].getEffects()[k]);
}
System.out.println();
}
在我的驅動程序類中，我試圖給測試生物添加「Sharp Eyesight」特性。
public class EvoDriver {
public static void main(String[] args) {
// initilize TraitList
TraitList myTraits = new TraitList();
// initilize Creature
Creature player1 = new Creature("Dragon Bear");
player1.addPop();
player1.addPop();
player1.growSize();
// add specific trait
//player1.addTrait(myTraits.getTrait("Carnivore"), 0);
player1.addTrait(myTraits.getTrait("Sharp Eyesight"), 1);
//player1.addTrait(myTraits.getTrait("Fire Breath"), 2);
//force update
player1.updateStats();
//print creature
player1.printCreature();
}
這是特質的構造函數。
public Trait(String newname, int fv, int[] effects)
{
if(DEBUG>0){System.out.println("DEBUG: TRAIT");}
traitname = newname;
feedvalue = fv;
//handle effects
effects[0] = feedertype;
effects[1] = size;
effects[2] = power;
effects[3] = stealth;
effects[4] = senses;
effects[5] = dangerous;
if(DEBUG>0){System.out.println("DEBUG: TRAIT > traitname = "+traitname);}
if(DEBUG>0){System.out.println("DEBUG: TRAIT > senses = "+senses);}
}
我有一個類，應該處理啓動stat稱爲TraitList每個特徵的提升。它包含每個特質的所有數據。但是，當調用方法「getEffects」時，結果始終爲0！
public class TraitList {
//DEBUG MODE
final int DEBUG = 1;
Trait[] allTraits = {new Trait("EMPTY",0,new int[]{0,0,0,0,0,0})};
// **** Constructors ****
/* HINTS
____________________________________________________________________________
effects[0] = feedertype;
effects[1] = size;
effects[2] = power;
effects[3] = stealth;
effects[4] = senses;
effects[5] = dangerous;
*/
public TraitList()
{
if(DEBUG>0){System.out.println("DEBUG: TRAITLIST ");}
boolean[] special = new boolean[2];
special[0] = false; //Alert the Herd
special[1] = false; //Pack Tactics
//add effects to list
// Sharp Eyesight; increases Senses by 3
//feedertype;
//size;
//power;
//stealth;
//senses;
//dangerous;
addTrait(new Trait("Sharp Eyesight", 2, new int[]{0,0,0,0,3,0})
.setDesc("Helps detect other creatures!"));
// Camouflage; increases Stealth by 3
addTrait(new Trait("Camouflage", 0, new int[]{0,0,0,0,0,0}));
// Alert the Herd; increases Senses by Population number
addTrait(new Trait("Alert the Herd", 0, special));
// Pack Tactics; increases Power by Population number
addTrait(new Trait("Pack Tactics", 0, special));
// Carnivore; creature can only eat meat; Senses +1, Stealth +1
addTrait(new Trait("Carnivore", -1, new int[]{0,0,0,0,0,0}));
// Omnivore; creature can eat meat and plants
addTrait(new Trait("Omnivore", -5, new int[]{0,0,0,0,0,0}));
// Horns; increases Dangerous by 1
addTrait(new Trait("Horns", 0, new int[]{0,0,0,0,0,0}));
// Fire Breath; increases Dangerous by 3, increases Power by 3; feed 10
addTrait(new Trait("Fire Breath", 10, new int[]{0,0,0,0,0,0}));
}
// **** Methods ****
public void addTrait(Trait newtrait)
{
// create temp array
Trait[] temp = new Trait[1];
temp[0] = newtrait;
Trait[] newtemp = new Trait[allTraits.length+1];
for (int k=0; allTraits.length>k;k++)
{
newtemp[k] = allTraits[k];
}
newtemp[allTraits.length] = temp[0];
allTraits = newtemp;
}
public Trait getRandomTrait() // to do
{
return null;
}
public int getTraitIndex(String searchname)//returns 0 if not found
{
for(int k=0;allTraits.length>k;k++)
{
if(DEBUG>0)
{System.out.println("DEBUG: TRAITLIST > getTraitIndex > k = "+k);}
if(DEBUG>0)
{System.out.println("DEBUG: TRAITLIST > getTraitIndex > "
+ "allTraits[k].getName() = "+allTraits[k].getName());}
if(searchname.equalsIgnoreCase(allTraits[k].getName()))
{
return k;
}
}
System.out.println("ERROR IN TraitList > getTraitIndex! TRAIT "
+ searchname +" DOES NOT EXIST!");
return 0;
}
public Trait getTrait(String name)//returns EMPTY trait if not found
{
return allTraits[getTraitIndex(name)];
}
}
我不知道該怎麼清楚，我一直在，但我非常感謝任何提示，建議，地獄我會帶一個有用的侮辱指出我的愚蠢的錯誤。我將附上我的調試輸出。

如果找不到解決方案，我可能會從頭開始。 （當然，我會重複使用一些工作代碼！）
請發佈整個'Trait'類。 –
