Ok. I know that you can make an explosion occur when the func_breakable breaks, but how can you make multiple explosions happen? I tried entering in the field both explosion names with a comma, and also with a ";", but it doesn't work. How do I do that?

use a multimanager (MM)

target the func_breakable to the MM, then goto the properties of the MM and turn smart edit off.

click add then type the name of the first explosion u want to add, and set the value to a number (how long in seconds that ur explosion will be triggered after the MM is triggered) then to add another just click add again

so for instance u wud have

Key - explosion1
Value - 0.1

that wud trigger "explosion1" 0.1 seconds after the MM was triggered

/edit spelling

i hope that helps, if not just ask me, and ill try again

for more information on the multi_manager entity

Sweet! It worked! Thank you

no problem dude, thats what this forums here for =]

just so you know, the explosion trigger will only work ONCE per loading of the map
(this made me remove paret of my old map)
if its an NS map, it shouldnt matter, but that can cripple a CO map

Well there's this map I play called co_freefall_rc1 and it has loads of func_breakables, so they just reload the map round.

The map I'm working on is going to have certain parts of the walls breakable, with very high damage, and then when it breaks the game is soon over because the hive is right by the cc.
