(处理)删除数组中以前使用过的对象
(处理)删除数组中以前使用过的对象
提问于 2014-11-24 03:10:46
抱歉，标题的措辞太糟糕了。我正在为我的编程类创建一个处理过程中的“战争”游戏。我需要更改我的代码，以便将使用的每一张卡从甲板/数组中删除。我偶然发现一些帖子和谷歌的结果提到了"ArrayList"，但我仍然有点不知所措。
下面的代码显示两个独立的随机卡片，并在单击鼠标时显示两个新的随机卡。
(第一次‘战争’)
void draw(){
image(card[imageIndex],40,150);
image(card2[imageIndex2],340,150);
}
void mousePressed(){
imageIndex = int(random(card.length));
imageIndex2 = int(random(card2.length));
}(第二张卡片)
PImage[] card = new PImage[13];
PImage[] card2 = new PImage[13];
int imageIndex = int(random(0,12)),
imageIndex2 = int(random(0,12));
void setup(){
size(500,500);
card[0] = loadImage("2_of_clubs.jpg");
card[1] = loadImage("3_of_clubs.jpg");
card[2] = loadImage("4_of_clubs.jpg");
card[3] = loadImage("5_of_clubs.jpg");
card[4] = loadImage("6_of_clubs.jpg");
card[5] = loadImage("7_of_clubs.jpg");
card[6] = loadImage("8_of_clubs.jpg");
card[7] = loadImage("9_of_clubs.jpg");
card[8] = loadImage("10_of_clubs.jpg");
card[9] = loadImage("jack_of_clubs.jpg");
card[10] = loadImage("queen_of_clubs.jpg");
card[11] = loadImage("king_of_clubs.jpg");
card[12] = loadImage("ace_of_clubs.jpg");
card2[0] = loadImage("2_of_clubs.jpg");
card2[1] = loadImage("3_of_clubs.jpg");
card2[2] = loadImage("4_of_clubs.jpg");
card2[3] = loadImage("5_of_clubs.jpg");
card2[4] = loadImage("6_of_clubs.jpg");
card2[5] = loadImage("7_of_clubs.jpg");
card2[6] = loadImage("8_of_clubs.jpg");
card2[7] = loadImage("9_of_clubs.jpg");
card2[8] = loadImage("10_of_clubs.jpg");
card2[9] = loadImage("jack_of_clubs.jpg");
card2[10] = loadImage("queen_of_clubs.jpg");
card2[11] = loadImage("king_of_clubs.jpg");
card2[12] = loadImage("ace_of_clubs.jpg");

使用ArrayList看起来有点像：
// gonna use strings instead of images
// just to show the idea. I don't have all this images...
ArrayList<String> card = new ArrayList<String>();
ArrayList<String> card2;
int imageIndex, imageIndex2;
String display1, display2;
void setup() {
size(500, 500);
card.add("2_of_clubs.jpg");
card.add("3_of_clubs.jpg");
card.add("4_of_clubs.jpg");
card.add("5_of_clubs.jpg");
card.add("6_of_clubs.jpg");
card.add("7_of_clubs.jpg");
card.add("8_of_clubs.jpg");
card.add("9_of_clubs.jpg");
card.add("10_of_clubs.jpg");
card.add("jack_of_clubs.jpg");
card.add("queen_of_clubs.jpg");
card.add("king_of_clubs.jpg");
card.add("ace_of_clubs.jpg");
card2 = new ArrayList<String>(card);
imageIndex = int(random(card.size()));
imageIndex2 = int(random(card2.size()));
display1 = card.get(imageIndex);
display2 = card2.get(imageIndex2);
card.remove(imageIndex);
card2.remove(imageIndex2);
println("\ncard draw from card : "+ display1);
println("card draw from card2: "+ display2 + "\n");
}
void draw() {
}
void mousePressed() {
if (card.size() > 0) {
imageIndex = int(random(card.size()));
imageIndex2 = int(random(card2.size()));
display1 = card.get(imageIndex);
display2 = card2.get(imageIndex2);
card.remove(imageIndex);
card2.remove(imageIndex2);
println("\ncard draw from card : "+ display1);
println("card draw from card2: "+ display2 + "\n");
} else {
println("The deck is empty...");
}

如果必须使用数组，则必须执行类似于以下代码的操作：
PImage[] removeCardFromDeck(PImage deck, int index){
PImage[] newdeck = new PImage[deck.length -1];
int count=0;
for(int i =0 ; i<newdeck.length;i++){
if(count==index) count++;
newdeck[i] = deck[count];
count++;
}
return newdeck;
}但是对于这个任务，最好使用ArrayLists。
