I've looked around, but haven't found a solid example on spawning a smoke (the kind a smoke grenade creates). Not sure if I should be looking toward the particle system or temporary entities for this.

Ideally I just want to spawn the smoke exactly as thrown from a smoke grenade at given coordinates. Even better would being able to adjust the duration of it.

I explored this a bit awhile back but never got to the point of mimicking the underlying effect that well. Ended up using an env_smokestake which looks quite a bit different. A few things I would try are spawning the weapon_smokegrenade and AcceptEntityInput(smokegrenade, "FireUser1")

The underlying effect is from the env_particlesmokegrenade entity, so it may be possible to create this, giving it the smoke material, materials/particle/...?, etc.

Ive done blood spatter particals by just using the partical name.

If you use the partical viewer in the sdk can you find the smoke partical effect?

Couldn't you just spawn a smoke grenade and detonate it right there?

As the other said you could simply use a smoke grenade and detonate it, but here is another solution which works too. The smoke is a bit different from the smoke grenades

int SmokeIndex = CreateEntityByName("env_particlesmokegrenade" );
if (SmokeIndex != -1 && iEntity != -1)
{
SetEntProp(SmokeIndex, Prop_Send, "m_CurrentStage", 1);
SetEntPropFloat(SmokeIndex, Prop_Send, "m_FadeStartTime", fadestart);
SetEntPropFloat(SmokeIndex, Prop_Send, "m_FadeEndTime", fadeend);
DispatchSpawn(SmokeIndex);
ActivateEntity(SmokeIndex);
TeleportEntity(SmokeIndex, vec, NULL_VECTOR, NULL_VECTOR);

Dr.api made a color smoke plugin before.
but this plugin didn't work anymore after valve change smoke_detonate event

Thanks, I'll try these out.

My attempt at detonating one normally spawns the grenade, but doesn't set it off (I can pick it up and detonate it myself)

float vec[3] = {-670.0, -1630.0, -104.77};
int ent = CreateEntityByName("weapon_smokegrenade");
DispatchSpawn(ent);
ActivateEntity(ent);
TeleportEntity(ent, vec, NULL_VECTOR, NULL_VECTOR);
bool success = AcceptEntityInput(ent, "FireUser1");
LogMessage("sent smoke, success = %d", success);

This does print "success = 1". Using FireUser 2-4 also didn't work, nor did passing myself as the 3rd arg (activator) to AcceptEntityInput. Any help would be appreciated.

zipcore's approach does get me a smoke effect, but I'd have to get all the properties tweaked for it to look normal.

Anyone any progress on this?

Still looking to make a "env_particlesmokegrenade" looking like a real smoke.

One way to do this:

PHP Code:

int entity = CreateEntityByName("smokegrenade_projectile");
TeleportEntity(entity, origin, NULL_VECTOR, NULL_VECTOR);
DispatchSpawn(entity); 


when you want it to explode:

PHP Code:

SetEntProp(entity, Prop_Send, "m_nSmokeEffectTickBegin", GetGameTickCount()); 


Things to keep in mind:
- The grenade will keep moving
- Smoke sound will not be made
- You will get "faded" screen when you get close to the grenade after it exploded. It stays until you remove the grenade, so when smoke disappears you will still get faded screen when you walk into it as grenade stays.
- The smoke doesn't follow the grenade
