我正在使用柏林噪声生成一个Map，并试图将坐标保存到一个json文件中。但由于某种原因，我面临的问题是，只有最后50个左右的坐标被保存到json文件中。
我也不确定我是否完全理解setjsonobject为什么将i作为它的第一个参数（我只是从文档中这样复制它以使其工作）
非常感谢你的帮助！
int tileSize = 20;
float scl = 0.1;
int[] x = new int [2000];
int[] y = new int [1000];
int[] terrainType = new int [2000];
JSONArray values;
void setup() {
size(1080, 720);
noStroke();
colorMode(HSB);
drawTerrain();
//ptintln(x, y);
}
void draw() {
}
void keyPressed() {
if (key == ' ') {
noiseSeed(millis());
drawTerrain();
}
}
void drawTerrain() {
values = new JSONArray();
for (int i = 0; i < width/tileSize; i++) {
for (int j = 0; j < height/tileSize; j++) {
x[i] = i;
y[j] = j;
JSONObject coordinates = new JSONObject();
coordinates.setInt("x", i);
coordinates.setInt("y", j);
values.setJSONObject(i, coordinates);
println(x[i], y[j]);
fill(getColour(i, j));
rect(i * tileSize, j * tileSize, tileSize, tileSize);
}
}
saveJSONArray(values, "data/new.json");
}
int getColour(int x, int y) {
float v = noise(x * scl, y * scl);
if (v < 0.3) {
//water
return color (155, 255, 255);
} else if (v < 0.4) {
//sand
return color (30, 255, 255);
} else if (v < 0.7) {
//grass
return color(66, 255, 255);
} else {
//forest
return color (80, 255, 200);
}
}这是println打印出来的：

我能为任何寻找答案的人找到答案：
基本上可以归结为以下几点：
显然地，
i必须是一个唯一的标识，用于标识存储到文件中的对象（或类似对象），如果存在重复的对象，则它将用相同的编号覆盖上一个对象。这就是为什么它只存储第二个系统的最后53个对象for循环的迭代。解决的办法是，几乎只是宣布一个新的
int count然后在第二个for循环中增加一次。然后使用它来标识传递给json文件的每个对象。
