How to make this "Special SCRIPT"

I can get my last boss so he dies the gate opens with this SCRIPT in Doom Builder:

#include "zcommon.acs"

Script 2 (void)
{
// LowerToLowest
Floor_LowerToLowest (2, 2);
}

Where the first "2" is the monster marked and the second "2" is the speed of action "going down the wall"

but...

How do I make my last boss as soon as he dies all the monsters die at once TOO?

That works to lower the gate when the boss dies?

OIC. The monster is the activator.

I think, Thing_Destroy is what you want.

{
Floor_LowerToLowest (2, 2);
Thing_Destroy (0, 0, 0);
}

Give all monsters a specific tag, and use Thing_Destroy in the script above.

I think you don't have to give them a tag if you're targeting them all. Just use zero. That's what they are by default.

from zdoom:
"If you have a TID of 0, then it will kill all the monsters on the map..."

A big thank you, it worked out "0, 0, 0" ... it was like I did not have to write "massacre" ... thank youuuuu!
