Here is a function to show tempents particles. Note that many of them (like rockettrail_! and flamethrower, see this pic) will not turn themselves off, so you'll have to spawn a particle system entity to control those. This method seems to work well with enties that end by themselves (like achieved and crit_text).

            attachpoint=-1,
            bool:resetParticles=true,
            Float:delay=0.0)
{
    // find string table
    new tblidx = FindStringTable("ParticleEffectNames");
    if (tblidx==INVALID_STRING_TABLE) 
    {
        LogError("Could not find string table: ParticleEffectNames");
        return;
    }
    
    // find particle index
    new String:tmp[256];
    new count = GetStringTableNumStrings(tblidx);
    new stridx = INVALID_STRING_INDEX;
    new i;
    for (i=0; i<count; i++)
    {
        ReadStringTable(tblidx, i, tmp, sizeof(tmp));
        if (StrEqual(tmp, Name, false))
        {
            stridx = i;
            break;
        }
    }
    if (stridx==INVALID_STRING_INDEX)
    {
        LogError("Could not find particle: %s", Name);
        return;
    }
    
    TE_Start("TFParticleEffect");
    TE_WriteFloat("m_vecOrigin[0]", origin[0]);

    if (entindex!=-1)
    {
        TE_WriteNum("entindex", entindex);
    }
    if (attachtype!=-1)
    {
        TE_WriteNum("m_iAttachType", attachtype);
    }
    if (attachpoint!=-1)
    {
        TE_WriteNum("m_iAttachmentPointIndex", attachpoint);
    }
    TE_WriteNum("m_bResetParticles", resetParticles ? 1 : 0);    
    TE_SendToAll(delay);
}

Forgot many things as TeamNum,player which fired and more..
Edit:
Can you explain how do we spawn a "particle system entity"?

Not sure what you mean about forgetting TeamNum and player which fired. These aren't weapon projectiles, just visual effects using the particle systems that come with TF2.

Spawning a particle system entity can be done like this:

public Action:DeleteParticles(Handle:timer, any:particle)
{
    if (IsValidEntity(particle))
    {
        new String:classname[STRLENGTH];
        GetEdictClassname(particle, classname, sizeof(classname));
        if (StrEqual(classname, "info_particle_system", false))
        {
            RemoveEdict(particle);
        }
        else
        {
            LogError("DeleteParticles: not removing entity - not a particle '%s'", classname);
        }
    }
}
public ShowParticle(Float:pos[3], String:particlename[], Float:time)
{
    new particle = CreateEntityByName("info_particle_system");
    if (IsValidEdict(particle))
    {
        TeleportEntity(particle, pos, NULL_VECTOR, NULL_VECTOR);
        DispatchKeyValue(particle, "effect_name", particlename);
        ActivateEntity(particle);
        AcceptEntityInput(particle, "start");
        CreateTimer(time, DeleteParticles, particle);
    }
    else
    {
        LogError("ShowParticle: could not create info_particle_system");
    }    
}
AttachParticle(ent, String:particleType[], Float:time)
{
    new particle = CreateEntityByName("info_particle_system");
    if (IsValidEdict(particle))
    {
        new Float:pos[3];
        GetEntPropVector(ent, Prop_Send, "m_vecOrigin", pos);
        TeleportEntity(particle, pos, NULL_VECTOR, NULL_VECTOR);
        GetEntPropString(ent, Prop_Data, "m_iName", tName, sizeof(tName));
        DispatchKeyValue(particle, "targetname", "tf2particle");
        DispatchKeyValue(particle, "parentname", tName);
        DispatchKeyValue(particle, "effect_name", particleType);
        DispatchSpawn(particle);
        SetVariantString(tName);
        AcceptEntityInput(particle, "SetParent", particle, particle, 0);
        ActivateEntity(particle);
        AcceptEntityInput(particle, "start");
        CreateTimer(time, DeleteParticles, particle);
    }
    else
    {
        LogError("AttachParticle: could not create info_particle_system");
    }
}

ShowParticle spawns it at a location. AttachParticle is basically the same thing but attaches it to an entity. You can also set attachement points by using SetParentAttachment (in the same way as SetParent above). For example, when I show healthgained_blu/red I attach it to the player's head.

You'll also need to set the entities targetname to something unique before calling AttachParticle (I use something like DispatchKeyValue(ent, "targetname", TargetName); where TargetName is "myentXXX" and the XXX is the entity ID or some other unique number).

I love you L.Duke


Particle achievements......awesome stuff!

[L. Duke]

Nice use of the achievements effect.

[DiscoBBQ]

L.Duke, Would you have any idea how to call an exploding player? I don't want the console command explode, I just want the animation and effects

I don't. The explode command calls the kill_helper function which sets the damage bits and calls the player's CommitSuicide function. The required effects may be handled client-side. I didn't see anything in the server .so file that looked promising, but I may have missed something.
