I would like to create a landmine that explodes when an explosion goes off near it, but not when it is shot. How was this accomplished in the Surface Tension levels? (you might be able to detonate them with bullets - i have never tried - but i would prefer it if it was not possible)
I could set a func_breakable to "pressure" or "touch" flags to active, and have them go off that way, but then they can be detonated by shooting them with anything.
any advice?
