Did we ever get the ability to make bombs stick to an actor?

Pretty easily coded with lua. IIRC multiple people already did implementations of the concept. Try doing a search for stuff like "sticky bombs" or the like

Or look at the lua code for the Coalition's Sticky Grenade Launcher, or so I thin at least.

I will do that. I have been out of the modding loop for a year, I had a Heart Transplant in October.

pretty sure the frag nailer shots stick to actors if you can hit them with the shots, they auto detonate a while afterwards tho as thats how the gun works

yeah just checked it out they do, and its got an LUA script you can look at as well.
