Stop spawning creatures after hive is destroyed?

Hi all! In my platform game I have an enemy hive that has creatures spawning behind it every 3 seconds. I set up the hive to be destroyed when I stomp on top of it, but I don't know how to stop the creatures from spawning once it's gone. My 2 separate events look like this:

1. (<system> every 3 seconds) = (<system> create object <creature>)

2. (<player> on collision with <hive> + Y < 820) = (<hive> destroy)

What kind of event could I create to stop the creatures from spawning once the hive is destroyed? Any help would be greatly appreciated! Thanks. <img src="smileys/smiley1.gif" border="0" align="middle" />

Create global variable = HiveAlive and set equal to 1

change

1. (<system> every 3 seconds) = (<system> create object <creature>)

2. (<player> on collision with <hive> + Y < 820) = (<hive> destroy)

to

1. (<system> every 3 seconds)

   (HiveAlive = 1)

= (<system> create object <creature>)

2. (<player> on collision with <hive> + Y < 820)

                        = (<hive> destroy)

                          (set HiveAlive to 0)

Awesome, that worked well! Thanks bigpappapuck. <img src="smileys/smiley16.gif" border="0" align="middle" />
