Yes I am this much of a noob SEN.

How do you add footsteps? Example trigger? I swear the wiki is like broken or something cause there's a bunch of nonexistent articles.

Two wikis and a tutorial, I can see how it can get confusing and break.

you have a pixel or inverted location the size of your unit and you center the location on the unit every time he moves out of the location, and play a sound every time he moves, or if thats too often, make it add a DC every time he moves out of the location and once its a certain number of DCs play a sound, that way you can tune it so its in sync.

Have a small location centered on your unit.
When the unit leaves that location play a wav then center the location again.
Adjust the size of the location to get the frequency of footsteps that you are looking for.

Hope that is clear enough for ya.

it's just going on a loop now. Anyone know how to fix that

Don't use an inverted location. Remember that when the unit is outside the location, you play the footstep sound then center the location back on the unit. If it still doesn't work, just post your map and we'll fix it.

tl;dt.
Use 1x1 pixel location.

inverted locations are good especially if your unit has an uneven collision box.
