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
0 F: ?9 J4 d+ s9 gpublic void spreadMoney(int money){: X/ d1 }* x7 j0 ^
// Randomly place money in moneySpace* M" b+ n8 F U1 N8 _

int x = (int)(Math.random()*(moneySpace.getSizeX()));

t7 w1 G6 m/ u; m% T \3 U d. m# M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?! j5 T" x% m. L* P; o
