我是一名文凭学生，是基于处理程序制作游戏的，这是一种塔防游戏，女主人公将朝着向城堡冲刺的僵尸射击箭。我对此有多个问题。
充电器僵尸被枪杀后不会重生。
当我仅拍摄一个充电器僵尸时，所有充电器僵尸都会死在一起。
假设我希望丧尸在击落一组敌人后反复产生波浪，然后我希望充电器丧尸单独死亡，具体取决于我单击的那个。

充电器的大部分问题都来自这里：
if (onScreen.size() == 0 && chargerIndex == numCharger) {
println("Game won! :)");
// gameWon = true;
}
// while onScreen charger less than 5 only and chargerIndex havent reach 300 it will only respawn
while (onScreen.size () < maxChargerOnScreen && chargerIndex <= numCharger - 1) {
if (chargerIndex < chargerArr.length) { // <--- this is the problem chargerArrayLength
Charger chargerMobs = chargerArr[chargerIndex];
// starts from chargerArray[0] to chargerArray[300]
onScreen.add(chargerMobs);
chargerIndex++;
// chargerIndex keeps looping why?
// println("ADDED ZOMBIE TO ONSCREEN Zombs on screen: " + onScreen.size());
}
}
// Adjusts maxZombOnScreen based off the current index Difficulties?
if (chargerIndex == 10)
maxChargerOnScreen++;
else if (chargerIndex == 50)
maxChargerOnScreen++;
else if (chargerIndex == 100)
maxChargerOnScreen += 2;
else if (chargerIndex == 150)
maxChargerOnScreen += 2;
else if (chargerIndex == 190)
maxChargerOnScreen += 3;
else if (chargerIndex == 250)
maxChargerOnScreen += 3;
else if (chargerIndex == 260)
maxChargerOnScreen += 3;
else if (chargerIndex == 270)
maxChargerOnScreen += 5;
// removes dead zombies, living zombies act normally
for(int i = 0; i < onScreen.size(); i++) {
Charger c = onScreen.get(i);
// add money when a zombie is dead
// if (c.getHealth() <= 0)
if (chargerShot==true) {
c.chargerDying();
onScreen.remove(i);
chargerKilled++;
i--;
} else {
c.act(); ///it should just act

}

最佳答案
该代码有几个问题，但现在，我将忽略有些“不干净”或“不优雅”的部分，而将重点放在引起该问题的主要问题上：
所有Charger实例的状态都相同。田野
boolean chargerReachedTarget = false, chargerShot = false, chargerDive = true;
已全局定义。只需将这一行（即这3个字段）移到
Charger类中，然后更改该行if (chargerShot==true) {
至
if (c.chargerShot==true) {
游戏似乎已经很接近您想找的东西了。修改后，可以射击单个对手，而在旧对手消失之后，新对手不断出现。
再说一遍：该代码的结构并不是很好，并且有许多可能的细微改进。例如，类似
if (c.chargerShot==true) { ... }的东西最好是if (charger.isShot()) { ... }。但是我对处理及其最佳实践不是很熟悉，因此我不确定在全球范围内“最佳”解决方案的外观如何……
