俄羅斯方塊代碼java

⑴ java編寫的俄羅斯方塊游戲

以下為一個渣鄭俄羅斯方塊的源代碼，以---------線分隔一個類。
郁悶太長了，不能全部粘貼上來，要的基梁並話搏跡在線M我吧。

⑵ 在這段java代碼--俄羅斯方塊，方塊是怎麼旋轉的

貼出來的代碼還不夠，不過已經基本能回答你的問題了
我的推理過程：從(turnstate+1)%4可以看出，turnstate是一個數字，取值只有0123，因此它僅僅是一個標識符，0123四種取值分別標記著這個方塊處於原狀，旋轉90度，180度或者270度。然後blow函數應該是一個判斷旋轉之後會不會出現和已有方塊重疊的函數。
因此，這個turn函數的功能是：把標識符變成下一個狀態，然後判斷如果旋轉，會不會和已有的方塊重疊，如果重疊，就取消這個旋轉標記的改變。
因此，答案就很明顯了：真正實現旋轉方塊的操作並不在這里，或者說，你再仔細研究一下這個程序的代碼，它可能實際上根本沒有旋轉過那個方塊，只是用turnstate這個數字標記方塊旋轉了多少度，判斷重疊以及繪制的時候才真正計算或者從表裡直接讀取旋轉後狀態而已。

⑶ java俄羅斯方塊旋轉演算法,求解

可以給每一個小方塊設置為一個坐標，變為一個三階行列式，3*3矩陣，轉變為二元數組旋轉。觀察一下左旋：

11 12 13 31 21 11

21 22 23 →→ 32 22 12

31 32 33 33 23 13

坐標變換如下：（1,1）變為（1,3），（1,2）變為（2,3），（1,3）變為（3,3）

（2,1）變為（1,2），（2,2）變為（2,2），（2,3）變為（3,2）

（3,1）變為（1,1），（3,2）變為（2,1），（3,3）變為（3,1）

規律就是（i,j）變為(j,3-i+1)：

如果是2*2的方格，就可以變為二階行列式，也就是2*2的二元數組，這里給出3*3九宮格改變的示意，我的代碼如下：

importjava.util.Random;

publicclassT{

publicstaticvoidmain(String[]args){

int[][]a=newint[3][3];
System.out.println("");
Randomr=newRandom();
for(inti=0;i<3;i++){
for(intj=0;j<3;j++){
a[i][j]=r.nextInt(10);
}
}
System.out.println("thearrayisshownasfollows:");
for(inti=0;i<3;i++){
for(intj=0;j<3;j++){
System.out.print(a[i][j]+"");
}
System.out.println();
}
System.out.println("左轉九十度");
for(inti=0;i<a.length;i++){
for(intj=0;j<a[i].length;j++){
System.out.print(a[a[i].length-1-j][i]+"");
}
System.out.println();
}
}
}
