Hi
I refer to my old topic http://www.killersites.com/community/index.php?/topic/4265-mysql-database-design/page__p__21707__fromsearch__1#entry21707 which was about my mysql database design.
Now, I wonder how I am going to trigger an EVENT for a certain time, For example, let's say I want to add a new building, it's going to take about 20 minutes until it's "builded".
If i want to upgrade it to "level 2" it will take a certain time, before it's updated, For example another 20 minutes. And when you upgrade, let's say you lose som resources like 200, 300, and so on.
How do I trigger actions after a few time?
