Is it possibel that a Hive will be destroyed by a triggert explosion. When yes can someone please tell me how?

Put an env_explosion near your hive, give it a name, next place a trigger_hurt with the same name that does 99999 damage and that covers the hive completely. When you trigger them, the explosion should show and the hive should die.

thanks that work really fine

That wont work all the time depending on a few things.

NS is a bit buggy about structures getting killed by enetities.

I use lasers to kill the hive and other structures since this ALWAYS seems to work unlike trigger hurt, and env explosion.

On the other hand explosions are a great way to destroy function breakables =)

Trust me on this one as it is a key component in my map co_PodRush.

OT: function weldables are buggy in co maps; you can walk through them and get stuck inside them easily.
