我正在尝试用java组合一个小游戏概念，并且遇到了一个奇怪的问题； int 数组似乎没有在我的代码的某些部分存储任何值!
(使用netbeans 8.2)
我怀疑这是我错过的一些小而乏味的事情。
这是基本生物的构造函数。看到“addTrait”方法了吗？这才是重点。
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);
}
这是Creature类中的方法。
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();
}
在我的驾驶员类(class)中，我尝试将“Sharp Eyesight”特征添加到我的测试生物中。
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();
}
这是特征的构造函数。
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);}
}
我有一个类，应该处理启动每个特征的统计提升，称为 TraitList。它保存每个特征的所有数据。然而，当调用“getEffects”方法时，结果始终为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)];
}
}
我不知道我说得有多清楚，但我非常感谢任何提示、建议，如果我指出我的愚蠢错误，我会接受有用的侮辱。我将附上我的调试输出。

如果找不到解决方案，我可能会从头开始。 (当然，我会重用一些工作代码!)
最佳答案
在构造函数中，您正在重新分配效果的值。这是潜在的问题。
effects[0] = feedertype;
effects[1] = size;
effects[2] = power;
effects[3] = stealth;
effects[4] = senses;
effects[5] = dangerous;
