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; y3 L$ m; J/ f: u- m( V
public void spreadMoney(int money){
/ {8 a" i1 A. ~2 e // Randomly place money in moneySpace
o# Z1 d0 G0 D! e9 m( z5 E2 ] for(int i = 0; i < money; i++){- {5 u! Z( D* S& l6 |8 O' M& W
* V9 c- ]% y( ^4 M- v) o- _
// Choose coordinates3 @0 B/ W Y. l) e( R
int x = (int)(Math.random()*(moneySpace.getSizeX()));& a. X1 ~1 D. S7 i
int y = (int)(Math.random()*(moneySpace.getSizeY()));1 R: |2 A* ^4 @$ A
/ l" |( y- A& z5 t# D- E
// Get the value of the object at those coordinates9 O& ?- q+ ]2 |4 `
int I;0 h# a7 B, H: k. ?
if(moneySpace.getObjectAt(x,y)!= null){) ~/ B1 g% g6 [& z2 @
I = ((Integer)moneySpace.getObjectAt(x,y)).intValue();
6 d$ }6 p( l( i$ t }
+ V+ n" Q( @' O2 @ else{$ U) i9 n- e, M) _8 l3 h& _
I = 0;2 e+ }, Q7 p( m% n. @+ H, V3 E
}, R* s! x! N1 i! r/ z9 V' T
// Replace the Integer object with another one with the new value
0 V$ {/ \3 r$ ~, X; O moneySpace.putObjectAt(x,y,new Integer(I + 1));( V% `. N H1 a
}+ I! x; X- ~& W7 @) X; A$ s
这里面if(moneySpace.getObjectAt(x,y)!= null){
, t: R2 q. T, C# b6 ?( \ I = ((Integer)moneySpace.getObjectAt(x,y)).intValue();" B4 R$ d% X ^
}
, N# |, I/ p8 m- ^ else{+ i, a& ?4 `+ _7 N% |( ]2 i1 p+ _ ^
I = 0;# c! H0 M7 @5 G" A* A p
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?
