XYZLocation仅存储3个整数和1个布尔值以及BlockLocation 2个整数。 这只是为了保存尽可能少的世界实例，而且还保存整数而不是双精度。
离岛是在玩家能够加入之前生成的，因此，如果有可能防止服务器发狂，这也将非常有用。
我为此工作了好几天，却无法找出解决方案，因此，感谢您提前提供的帮助。

您的代码中有很多循环，您应该对其进行一些优化。 例如，此getRollingParticle不应小一些吗？

您在代码中创建了一个无限循环，具体取决于所生成的随机数，噪声将保持在-1以下，从而导致y for循环永远不会执行，因此变量hb永远不会更新为除0以外的任何其他值。使可变噪声永远不低于0并不是一个好的解决方案，因为对于任何坐标，总是存在这样的风险，即噪声可能会在0到35之间徘徊，从而再次引起bug。
该错误的解决方案是更改代码以在生成器的第四维噪声谱中选择一个不同的点，然后再次尝试使用该点以查看它是否产生了至少35高度的更好噪声。
为此，将执行以下操作：
int attempt = 0;
while(highestBlock < 35) {
attempt++;
blocks.clear();
int hb = 0;
for(int x = 0; x < xWidth; x++) {
for(int z = 0; z < zWidth; z++) {
double noise = gen.noise(x, z, attempt*5, 0.5, 0.5) * HEIGHT * rollingParticle[x + z * xWidth];
double noisePlusOne = noise + 1;
for(int y = 1; y < noisePlusOne; y++) {
if(y > hb) hb = y;
if(y == ((int)noise)) {
blocks.add(new XYZLocation(x, y, z, true));
} else {
blocks.add(new XYZLocation(x, y, z, false));
}
}
}
}
System.out.println("max:" + hb);
highestBlock = hb;
}
请注意，我添加了一个system.out调试语句以打印出最大块数，尝试解决孤岛高度冲突时，您应该看到它有所变化，如果仍然花费很长时间，则可能需要将第三个参数增加到gen.noise，例如，使用attempt*10使其在噪声频谱中移动得更快。
我建议您使用该参数，以查看产生最佳结果的参数。
