我正在寫一個簡單的tictactoe遊戲,每個玩家可以是人或AI。 所以創造遊戲的新實例,我做到了,使得我要做的就是:如何讓java等待事件?
Player p1=new RLPlayer(world);
gameInstance = new GameInstance(this, p1, new HumanPlayer(this, world), world);
但是,如果我這樣做
Player p1=new RLPlayer(world);
gameInstance = new GameInstance(this, p1, new HumanPlayer(this, world), world);
Player p2=new RLPlayer(world);
gameInstance = new GameInstance(this, p2, new HumanPlayer(this, world), world);
只有1場比賽得到發揮。我發現這是由於這樣一個事實,即對於HumanPlayer來說,它在等待移動輸入時停止並且什麼也不做,如果之後的代碼就會跳過。如何讓執行等待輸入?或者我的方法完全錯誤?我有一種感覺。
public class HumanPlayer implements Player {
private GameGUI gameGUI;
private TicTacToeWorld world;
public HumanPlayer(GameGUI gameGUI, TicTacToeWorld world){
this.gameGUI = gameGUI;
this.world = world;
}
public boolean makeMove() {
gameGUI.setMoveInputEnabled(true);
return false;
}
public boolean makeMove(int move){ //false means no move made
if(!world.isMoveLegal(move)) return false;
world.makeMove(move);
gameGUI.setMoveInputEnabled(false);
return true;
}
public void observeMove(){
}
}
僅適用於某些情況。我認爲問題在於上面的問題。
public class GameInstance {
private Player[] players;
private TicTacToeWorld world;
private GameGUI gameGUI;
public GameInstance(GameGUI gameGUI, Player player1, Player player2, TicTacToeWorld world){
this.gameGUI = gameGUI;
players = new Player[]{player1,player2};
this.world = world;
runGame();
}
public void runGame(){
gameGUI.updateGUI(world.getWorldState());
while(!world.isGameOver()){
if(!makePlayerMove())return;
gameGUI.updateGUI(world.getWorldState());
}
}
public boolean makePlayerMove(){
int[] state;
state = world.getWorldState();
if(players[(state[0]-1)%2].makeMove()){
players[state[0]%2].observeMove();
return true;
}
else
return false;
}
public void makePlayerMove(int move){ //force move AI OR input human move
int[] state;
state = world.getWorldState();
if(players[(state[0]-1)%2].makeMove(move)){ //if move was made e.g. AI. Human player would return false;
gameGUI.updateGUI(world.getWorldState());
players[state[0]%2].observeMove();
runGame();
}
}
}
研究觀察者模式... – Thihara
這裏的狀態模式可能會更好。 –
我googled這些模式,但我沒有得到他們如何消除需要讓程序等待。你能給一個簡短的解釋嗎? – kokocrunch
