There was a problem hiding this comment.
I honestly have no idea if the distance numbers I chose for these InsertSound calls make sense. I estimated them assuming that a player width is 32 units.

Description
Emit sound entities for bots to detect player cloak/footstep sounds. While existing EmitSound() calls play sounds for humans, bots did not detect those sounds. Adding InsertSound entities allows bots to react to cloak and footsteps as additional significant sound emissions to react to.
The lack of bot reactivity to footsteps and cloak was made more apparent in PR #1795 where bots lay detpack traps. Before this change, bots did not react to footsteps or cloak, but they did react to gunfire.
