一眼就看到
//Minimum difference between two different ads (float)
new const Float:RAND_MIN = 60.0;

//Maximum difference between two different ads (float)
new const Float:RAND_MAX = 80.0;

I am thinking how to change the min and max..這源碼的min max意義是什麼 什麼的最大最小

"I am thinking how to change the min and max"
懂得用英文回應我的話那幾句英文應該也看的懂吧
RAND_MIN=minimum time
RAND_MAX=maxmum time
if you don't know this english
i cannot help you

Ok,thanks. 大致上明白了..
