In the sounds folder there is a File called materials, or something like that, so u need to set it to play your sound, but if u give some1 the map and they use it, they will just hear the generic footstep shit because they don't have it modified

and sorry for my bad spelling

just apply your custom texture to the ground , then make the trigger when walked on to play your sound

i believe there manually set the sound for you...

Like if you put snow texture you will get snow foot steps .

Dirt , you'll get dirt foot steps ..

so i think there no need to mess around with setting

Q. How do I change weapons players get/buy?

Give weapons to players on start
Create one single game_player_equip for all players in the map. You can set what weapons will be given in the entity's properties, or even make the players spawn with sparks flying around!
Note the more than one weapon of each category can be given at once. e.g. A player can receive AWP, M4A1 and AK47 all at once!
