Just like my movable machine gun plugin that you can carry the gun
Anyway good plugin , another plugin using the info_particle_target

Here are some ideas.
Add a cvar to control the attack range and the angle of detection. Also add sone ammo types eg. Fire , explosive , heal , freeze,knockback

Thank you for your guidance.
The beginning of the idea is create a weapon auto attack inftects, the weapon is on your shoulder, like predators in movie, but I find no appropriate model to use, and my hammar tool do not work.

Attack range and damage type are written directly in code , not yet make convars.

Another question to ask, the code below do not work in l4d1, the bullet track start from pos but not end with endpos, "info_particle_target" even do not exsit.

Code:

ShowTrack(  Float:pos[3], Float:endpos[3] )
{  
     decl String:temp[32];        
    new target =0;
    if(L4D2Version)target=CreateEntityByName("info_particle_target");
    else target=CreateEntityByName("info_target"); 
    Format(temp, 32, "cptarget%d", target);
    DispatchKeyValue(target, "targetname", temp);    
    TeleportEntity(target, endpos, NULL_VECTOR, NULL_VECTOR); 
    ActivateEntity(target); 
 
    new particle = CreateEntityByName("info_particle_system");
    if(L4D2Version)    DispatchKeyValue(particle, "effect_name", PARTICLE_WEAPON_TRACER2);
    else DispatchKeyValue(particle, "effect_name", PARTICLE_WEAPON_TRACER);
    DispatchKeyValue(particle, "cpoint1", temp);
    DispatchSpawn(particle);
    ActivateEntity(particle); 
    TeleportEntity(particle, pos, NULL_VECTOR, NULL_VECTOR);
    AcceptEntityInput(particle, "start");    
    CreateTimer(0.01, DeleteParticletargets, target, TIMER_FLAG_NO_MAPCHANGE);
    CreateTimer(0.01, DeleteParticles, particle, TIMER_FLAG_NO_MAPCHANGE);
}

Finally! I knew someone would make this. Just sad this was the first thing I tried to achieve with SourceMod, 2 years ago. (Left 4 Dead 1, playing as a special infected and forcing me to control it)

Hey thanks it worked realy great, but I guess I have a bug and most likely cause my server runs survival, this is the second day and nobody is able to spawn the gun, it will say too many machine when you try to spawn one, I increased the amount allowed and then was able to spawn more, but now just cant spawn any even after map change.

If you need more info about what is running on my server let me know!

BTW the tankrock plugin works great on my server, no errors or crashes hm it crashes my versus server tho

Thanks allot for all your hard work,

Mega

    CreateTimer(0.01, DeleteParticles, particle, TIMER_FLAG_NO_MAPCHANGE);
}

yeah info_particle_target only exist in l4d2
I think for l4d1 you should use the same method as before to create the gun fire
