练习:for循环

box() --创建box
--创建一个50*50的box阵列
for a in 0 to 50 do
    (
        
        for i in 0 to 50 do copy $Box001 pos:[25*a,i*25,0] 
            
    )
    
--给box的wirecolor设置随机颜色
for i in selection do
(
    rNumber=random 0 255
    i.wirecolor=(color rNumber rNumber rNumber)--(random black white)--color (random 1 255) (random 1 255) (random 1 255)
    
    )
    
    
--设置box的高度为10-50的随机数    
for i in selection do 
    (
        
        i.height=random 10 50
        
        )
