大家都看过carrydrop的程序吧,里面设置moneyspce时将钱任意分布在空间中9 A8 L# d. S" ^
public void spreadMoney(int money){3 C7 P1 O+ X5 l! R( g) B7 p( A
// Randomly place money in moneySpace
& o9 Y& C: T. _ E0 i" h7 L1 T for(int i = 0; i < money; i++){3 q) m, p6 Q8 I. l) i! }
( e8 f1 i, }7 q' J6 i
// Choose coordinates
! V; ^4 D) d. @9 C+ L9 L int x = (int)(Math.random()*(moneySpace.getSizeX()));
* J a; M) A+ S2 F4 o int y = (int)(Math.random()*(moneySpace.getSizeY()));7 Q0 d% n% m2 c8 B8 p) R
. l/ R3 g. M' E d, [ F2 n7 T, b6 B // Get the value of the object at those coordinates/ o: t6 r" T6 |/ Q" |+ C: Y: C
int I;
% B; H$ G' Y8 p6 C; H# v) g4 ] if(moneySpace.getObjectAt(x,y)!= null){( _( n& Z6 d: V) l& K% H
I = ((Integer)moneySpace.getObjectAt(x,y)).intValue();
* J' F& O' i+ R. J } g3 }( s7 P9 {0 h/ ~0 j% X/ W
else{: \1 L; I Y- V) {- E
I = 0; W, x8 Y0 |* g+ U9 J7 t
}
5 m" V( b2 X. s, e I // Replace the Integer object with another one with the new value
4 u2 U; Q' c0 ?$ e5 U moneySpace.putObjectAt(x,y,new Integer(I + 1));
- `) Z: n! @- K* I4 B }
. j; O# m+ V0 B+ P$ w% T这里面if(moneySpace.getObjectAt(x,y)!= null){
* r ^, _5 b2 `5 @ I = ((Integer)moneySpace.getObjectAt(x,y)).intValue();1 h1 k8 M2 s" L& n0 j- t9 X
}
! c3 k9 A& C" M* z2 e else{
. Y! R! b6 N3 i+ T I = 0;0 r; L- T) j! u5 g* K& ?4 \
是在干什么啊?为什么后面的moneySpace.putObjectAt(x,y,new Integer(I + 1));要用new Integer(I + 1),这都在原来钱的基础上加一啊,我怎么看不出来是随意放置钱财的呢?& j. l% Q" d2 l6 }! l2 Q
