mdl edit attack sound

i have manny new models with their own new projectiles, now there is no sound if they attack, how can i add a sound to them via mdl editing?

Sounds are added through EventObjects, which look like this:

EventObject "SNDXASPS" {
ObjectId 7,
EventTrack 1 {
2400,
}
}

That 8-letter code tells what it is. SND means that it's a sound. X is used to make this particular code unique. ASPS is the code cooresponding with the sound. The coorespondences can be found in UI\SoundsInfo\AnimLookups.slk .

The ObjectId is just like any other; just line them up.
The EventTracks showwhen to play. In this case, it plays during frame 2400.

is that the way like u added the deathsound avatar screem to your sc models?

You're welcome and yes.
