爲圖像分配一個值

Question

所以我想創建一個真正簡單的骰子游戲...更像是一個骰子游戲，我遇到了一個問題，我還沒有找到答案。所以顯然我有6張圖片（1-6），但我在某處丟失的是如何在「骰子滾動」時爲這些圖片分配值。所以當我開始實施一些遊戲邏輯時，我可以比較模具面的數量。這是我迄今爲止所做的，和往常一樣，任何援助都將受到高度讚賞。

public class CrapsGameActivity extends CrapsActivity { 
    private final int rollAnimations = 50;

     for (int i = 0; i<6; i++){

     }

我可能沒有正確地做，但代碼（下）。當我使用它來查看模擬器上的數字時，它們是隨機的，並且不對應於骰子的面值。所以，如果我想總計骰子的面值（現在再次運行它），0代表6張臉，2代表3張臉，這應該給我一個9的總骰子面，但我得到2

public void onClick(View v) { 
       try{ 
        rollDice(); 
        die1_Total.setText("" + roll[0]); 
        die2_Total.setText("" + roll[1]); 
        diceTotal.setText(""+ diceSum); 
       }catch(Exception e) {}; 

Answer 1

roll[0] = randomGen.nextInt(6); 
roll[1] = randomGen.nextInt(6); 

有自己的價值觀。你不希望圖像包含數據（或者至少，我不會打擾）。相反，您基於這些值呈現圖像/動畫，然後可以在稍後直接使用這些值。

如果你想存儲圖像的值，你總是可以創建一個對象（GameDie）並將圖像和當前值存儲在那裏。
