出于某种原因，“numAlive”变量显示为 3，但当传递回 numAlivePass 时，它显示为“0”这是康威人生游戏
根据下面的评论编辑
public int countLiveNeighbour(int x, int y){
int numAlive = 0;
if(x >= 3 && y >= 3 && x < HEIGHT-3 && y < WIDTH-3)
{
if(generation[x][y+1] == ALIVE) {numAlive++;}
if(generation[x][y-1] == ALIVE) {numAlive++;}
if(generation[x+1][y] == ALIVE) {numAlive++;}
if(generation[x+1][y+1] == ALIVE) {numAlive++;}
if(generation[x+1][y-1] == ALIVE) {numAlive++;}
if(generation[x-1][y-1] == ALIVE) {numAlive++;}
if(generation[x-1][y+1] == ALIVE) {numAlive++;}
}
if(x ==31 && y==16){
System.out.println("ALIVE INclass: " + numAlive);
}
return numAlive;
}
//cell will be alive in next generation if alive cells = 3 or if already alive then 2 or 3
private int aliveCell(int x, int y){
int numAlivePass = 0;
numAlivePass = countLiveNeighbour(x, y);
if(x ==31 && y==16){
System.out.println(" NumAlivePass(ed) = " +numAlivePass+ " Live Neighbour Call = " + countLiveNeighbour(x, y));
}
int aliveState= 0;
if(x ==31 && y==16){
System.out.println(x + " x val 1, " + y + " x val 1, ALIVE 1: " + numAlivePass + " Alive State 1: " + aliveState);
}
if (numAlivePass > 3 || numAlivePass < 2){
aliveState = DEAD;
}
if(numAlivePass == 3){
aliveState = ALIVE;
System.out.println("Alive");
}
if (generation[x][y] == ALIVE && numAlivePass == 2){
