Noise detection AI

[imcrx_zyy (maria)]

I want to achieve a good Doors fangame, and I would like to know how to make an AI that detects footsteps.
How do I do this?

Making enemies respond to sound

I mentioned my past project because the same general idea can still be applied to your game. Whenever your gun is fired, you can go through a list of NPC’s in the level and check their distance from the player. If they are within range of the sound, move the NPC’s towards the player. Or, if you like, you can skip the entire process of checking the NPC’s distance to the player, and just start moving them towards the player immediately after they fire a gun.
