我正在用 C++(openFrameworks)构建一个生命 CA 游戏。由于我是 C++ 新手,我想知道是否有人可以让我知道我是否在以下代码中正确设置了向量。CA 没有绘制到屏幕上,我不确定这是否是我设置矢量的结果。我必须使用一维向量,因为我打算将数据发送到仅处理一维结构的纯数据。
GOL::GOL() {
init();
}
void GOL::init() {
for (int i =1;i < cols-1;i++) {
for (int j =1;j < rows-1;j++) {
board.push_back(rows * cols);
board[i * cols + j] = ofRandom(2);
}
}
}
void GOL::generate() {
vector<int> next(rows * cols);
// Loop through every spot in our 2D array and check spots neighbors
for (int x = 0; x < cols; x++) {
for (int y = 0; y < rows; y++) {
// Add up all the states in a 3x3 surrounding grid
int neighbors = 0;
for (int i = -1; i <= 1; i++) {
for (int j = -1; j <= 1; j++) {
neighbors += board[((x+i+cols)%cols) * cols + ((y+j+rows)%rows)];
}
}
// A little trick to subtract the current cell's state since
// we added it in the above loop
neighbors -= board[x * cols + y];
// Rules of Life
if ((board[x * cols + y] == 1) && (neighbors < 2)) next[x * cols + y] = 0; // Loneliness
else if ((board[x * cols + y] == 1) && (neighbors > 3)) next[x * cols + y] = 0; // Overpopulation
else if ((board[x * cols + y] == 0) && (neighbors == 3)) next[x * cols + y] = 1; // Reproduction
else next[x * cols + y] = board[x * cols + y]; // Stasis
}
}
// Next is now our board
board = next;
}
