So im using the SFX system that Package_Complex uses for my weapons and im having trouble implementing sounds played from locations that projectiles land.
Heres the support script:
function strStart(%str, %search)
{
return getSubStr(%str, 0, strlen(%search)) $= %search;
}
function strEnd(%str, %search)
{
%len1 = strlen(%str);
%len2 = strlen(%search);
return strlen(%len1) >= strlen(%len2) && getSubStr(%str, %len1 - %len2, %len2) $= %search;
}
function strStartCut(%str, %search)
{
return getSubStr(%str, strlen(%search), strlen(%str));
}
function strirpos(%str, %search)
{
%len = strlen(%search);
for (%i = strlen(%str) - %len; %i >= 0; %i--)
{
if (getSubStr(%str, %i, %len) $= %search)
return %i;
}
return -1;
}
function SFXEffect::onAdd(%this)
{
%name = %this.getName();
if (%name $= "")
{
error("ERROR: SFXEffect objects must have a name!");
%this.delete();
return;
}
// If this is a duplicate, delete the old one.
%this.setName("");
%original = nameToID(%name);
%this.setName(%name);
if (%original != -1 && %original.class $= "SFXEffect")
%original.delete();
// Go through fields to discover all layers
// We'll have to use local variables for everything because this looks
// through the fields of %this, and we don't want to mess it up.
for (%i = 0; 1; %i++)
{
%tag = %this.getTaggedField(%i);
if (%tag $= "")
break;
%field = getField(%tag, 0);
%value = getFields(%tag, 1, getFieldCount(%tag));
// This part is really repetitive because we can't use fields here
// Sorry! :P
// Technically it could be cleaned up with globals but that's a whole
// other can of worms
if (strStart(%field, "file"))
{
%field = strStartCut(%field, "file");

}
and using this guy
FireSFX.playFrom(%obj.getMuzzlePoint(%slot), %obj);
I can play a set of audio from the position "MuzzlePoint"
Now i want to be able to play the SFX when a projectile explodes or collides with the ground but im not sure how to write it out so it gets the location of the projectile and plays the SFX from there.
The HE grenade in Package_Complex does this
HEGrenadeExplodeSFX.playFrom(%position, %object);
but ive tried this with my weapons plus other variations (which is basically just me plopping random variables) and ive gotten no luck.
Can someone show me how to set this up or tell me what im doing wrong?
This is what i have for the projectile that im using
function SMAWProjectile::onCollision(%this, %slot)
{
ATExplosionSFX.playFrom(%this.getPosition(%slot), %this);
}
