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) C/ h. n( M* \, a% u) w
public void spreadMoney(int money){
" P) o9 @& J% f7 j% S( q) a // Randomly place money in moneySpace
, [& W6 [# n3 M5 V- l" A for(int i = 0; i < money; i++){$ m; f& ]' `# d- g/ @3 l
& Z; S( m1 J5 v7 I. [ // Choose coordinates
7 `' Q7 k' ^5 ]2 O1 [ int x = (int)(Math.random()*(moneySpace.getSizeX()));& k( E7 y0 r4 M* i/ Q
int y = (int)(Math.random()*(moneySpace.getSizeY()));
' D; `: s2 s/ g. e& q
- r0 |3 k& C, b6 Q // Get the value of the object at those coordinates( Z4 g0 F/ \6 \, _4 E5 R2 U, v0 ~
int I;) e& e- b! r+ |- w
if(moneySpace.getObjectAt(x,y)!= null){
. u6 E' t$ }6 O* n5 Y4 O+ \( e I = ((Integer)moneySpace.getObjectAt(x,y)).intValue();0 u: v5 V, i: l, w* m4 r+ l
}% h3 f" f5 H9 Z. P m
else{
4 w2 o! `7 @9 T' e, k- S I = 0;( z1 [$ l1 R- k5 i1 C4 p2 c
}
. A* o2 \7 L" l // Replace the Integer object with another one with the new value
' A- t- m' H1 v" }- F2 Z: k moneySpace.putObjectAt(x,y,new Integer(I + 1));
0 L- ^, E" x; m2 f6 I }% \4 A. k1 X6 S
这里面if(moneySpace.getObjectAt(x,y)!= null){
" [ U+ F$ V* X$ |% A I = ((Integer)moneySpace.getObjectAt(x,y)).intValue();2 p+ O8 |* R3 \. V
}
2 Q& _/ P1 {+ f else{
% V3 k, H+ T I' k* _ U7 K I = 0;
* i3 v4 J) P$ H3 U% W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?. e( z3 p; n1 n1 M% l x }
初学者,还请见谅! |
