Hi! So I have been working on a project that requires me to use a 2D array. I have been trying to loop over this with the for loop, but it doesn’t seem to be working. Here’s my code.
//World Variables
int seed; // The seed used by the program to generate the world.
int worldW, worldH; // The width and height of the world
Tile[][] world; // The world array
boolean worldGenerated;
// Camera Variables
float zoom; // How zoomed int the camera is.
PVector cam; // The camera's location
void setup() {
size(1366, 768); // The size of the window. I would recommend using your screen's native resolution.
// Seed Variables
seed = 1234;
randomSeed(seed);
// World Variables
worldW = 1000;
worldH = 1000;
world = new Tile[worldW][worldH];
worldGenerated = false;
// Camera Variables
zoom = 0.2;
cam = new PVector(0, 0);
keysDown = new ArrayList<String>();
background(0);
}
void draw() {
background(0);
if (!worldGenerated) {
generateWorld();
}
for (int x = 0; x > worldW; x = x + 1) {
for (int y = 0; y > worldH; y = y + 1) {
world[x][y].drawTile();
}
}
if (keyPressed) {
if (key == '-') {
zoom += 0.001;
} else if (key == '=') {
zoom -= 0.001;
} else if (key == 'w') {
cam.y -= 1;
} else if (key == 's') {
cam.y += 1;
} else if (key == 'd') {
cam.x += 1;
} else if (key == 'a') {
cam.x -= 1;
}
}
}
void generateWorld() {
for (int x = 0; x > worldW; x = x + 1) {
print("test");
for (int y = 0; y > worldH; y = y + 1) {
world[x][y] = new Tile(x * 10, y * 10, 10, 10, 10);
}
}
worldGenerated = true;
}
Tile:
class Tile {
float tHeat, tHumitity, tHeight;
PVector location;
Tile(int x, int y, float tHeat, float tHumitity, float tHeight) {
this.tHeat = tHeat;
this.tHumitity = tHumitity;
this.tHeight = tHeight;
this.location = new PVector(x, y);
}
public void drawTile() {
noStroke();
fill(map(tHeat, 0, 1, 0, 255), map(tHeight, 0, 1, 0, 255), map(tHumitity, 0, 1, 0, 255));
rect((this.location.x + cam.x) / zoom, (this.location.y + cam.y) / zoom, 10 / zoom, 10 / zoom);
}
}
Can you please help me?
Thanks!
