Day 2
Today i created little test area with main existing objects. Red sphere is a bomb, green pyramide - HackGun, yellow cube - terminal, green flat cylinder is a finish.
I added collider to every of them, so now they can somehow work. Finish Place and terminal print messages when you is nearby, bomb explodes and kills you, and also you can pick up HackGun. ALSO, i could emit Raycast from HackGun and determine what it targets to. And if target is a bomb - explode it from distance. Now i think how disable bomb and mb other mechanisms in future, but not destroy them.
