Without spoiling too much, I'm destroying a baddie with a script, but it doesn't actually "kill" him. You know, with a yell and smoke, etc. . .he just disappears. I got the sound taken care of easily enough, but it is an incredibly vacant effect without the smoke or something similar to accompany his sudden vanishing. Figure some of you fellas have come up with a few creative workarounds already, so thought I'd ask for advice before tearing the engine down to find a solution. (again!)
Any pointers gents?

You can look up / try out all of the particle systems that come packaged with the game by looking in 'asset_pack_v2/assets/particles/' folder. I'm sure there are more applicable / unique ones out there in the community - but one of the built in ones might just do you fine.

I don't know what 'death_dust' or 'hit_dust' look like, but they might be worth a shot?

Hey mate when i make a Monster disapear with a Teleporter or something else i use the FX (death_smoke) with party:shakeCamera, playSound, hudPrint("Ill be backkkkk") (LOL). Simular to party xy position but Monster xy Position.

--Die Monster Die Hook--
I clone a Monster give it a new name and add the Ondie Hook to the new monster which allows you do things, like (above) its awesome..
EG: Ghoul cloned and when the Ghoul dies, doors open, sound, spawn fx, text, and drop item for a puzzle..

I did find away to - When the Monster gets to a ceratain Health level a teleporter would activate and send the monster somewhere else on the same level, with the Smoke ,sound and text..But i lost the object.lua Script and the Editor Scripting sorry...

Is this what you are looking for??
Ill find the Particle Sys for you if you wantm or I think its part of the assets pack2..
