Hi !
I want to make boss battle on my map however i don't know how to create bombs that will target players like in original portal 2 campaign.
Thanks for answer.

You can put an info_target on the part of the body where the bombs should fly towards.
Then put in a logic_auto
Onmapspawn <info_target name> setparent !player

Then put the trigger_catapult's target to be the info_target name's

thank you soo much. It's working

Alternately, Valve actually used the point_futbol_shooter entity for the final boss fight. Send it a SetTarget input with a parameter of "!player", and then trigger the "ShootFutbol" input every time you want a bomb to be thrown.
