I'm generating a map using perlin noise and attempting to save the coordinates to a json file. But for some reason the problem I'm facing is that only the last 50 or so coordinates are getting saved to the json file.
I also am not sure I fully understand why the setJSONObject takes i as its first parameter (I just copied it like that from the documentation to make it work)
Your help is very appreciated!
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);
}
}
This is what Println prints out:
