it can be done with Easy FX? or you dont try it?

tbh I really don't mind what way people go about putting the FX in their map, they can use Phil's or they can use Trem's Easy FX, don't really mind, once again the reason I done the client script way in this tutorial is to cover everyone, I could put Easy FX Tutorial here but then not everyone is using Easy FX, but I know for a fact this method will work for everyone.

My end goal is that for people that who want that Black Ops 2 wall weapon FX in their map, can do so using this, and if they want to use another method to put it in their map, then that's ok.

Alright, just trying help. I didn't see you deleting the origin after adding it, so figured I'd make a suggestion that doesn't contribute to gspawn, and makes your life a bit easier, is all. But really, you should be able to incorporate this into the weapon prob. Without doing easy fx or csc. Just by adding like one line to _zombiemode_weapons, for the play fx part.

I'll look into that, I was not aware also leaving the script_origin could contribute to a g_spawn error. lol I added to the tut to tell people to delete it.

How is this different/better to this?

This one by Bam seems a lot easier to implement also, no need to mess around with coordinates in Radiant.

Well this tut is dif cause bam spawns an ent. This tut doesn't. But really, you can just play fx on the weapon, it is an ent too. Or even play fx at the origin of the trig, unless the angle matters.

Well I tried doing it but I am new to scripting so it's all trial and error for me and obviosuly this is error.

My #1 attemt was via just adding playfx to the original funtion in _zombiemode_weapons.gsc like so:

init_weapon_upgrade()
{
	weapon_spawns = [];
	weapon_spawns = GetEntArray( "weapon_upgrade", "targetname" ); 
	playfx("wall_weapon_light", weapon_spawns.origin);

	for( i = 0; i < weapon_spawns.size; i++ )
	{
		hint_string = get_weapon_hint( weapon_spawns[i].zombie_weapon_upgrade ); 

		weapon_spawns[i] SetHintString( hint_string ); 
		weapon_spawns[i] setCursorHint( "HINT_NOICON" ); 
		weapon_spawns[i] UseTriggerRequireLookAt();

		weapon_spawns[i] thread weapon_spawn_think(); 
		model = getent( weapon_spawns[i].target, "targetname" ); 
		model hide(); 
	}
}

When that didn't work I just made a new GSC and called it in my maps GSC:

wall_weapon_light_fx()
{
	weap_light = getEntArray("weapon_upgrade","targetname");
	loadfx("weapon/fx_wallweapon_light");
 
	while(1)
 
	{
		playFX("wall_weapon_light", weap_light.origin);	
                wait 0.5;
	}
 
 
 
}

But didn't work either, if I could get this to work it would make the whole process 100 times easier.

init_weapon_upgrade()
{
	weapon_spawns = [];
	weapon_spawns = GetEntArray( "weapon_upgrade", "targetname" ); 
	// playfx("wall_weapon_light", weapon_spawns.origin); // not here

	for( i = 0; i < weapon_spawns.size; i++ )
	{
		hint_string = get_weapon_hint( weapon_spawns[i].zombie_weapon_upgrade ); 

		weapon_spawns[i] SetHintString( hint_string ); 
		weapon_spawns[i] setCursorHint( "HINT_NOICON" ); 
		weapon_spawns[i] UseTriggerRequireLookAt();

		weapon_spawns[i] thread weapon_spawn_think(); 
		model = getent( weapon_spawns[i].target, "targetname" ); 
                
                playfx("wall_weapon_light", weapon_spawns[ i ].origin); // here instead, so it plays per member of the array, using the member as a point of origin

		model hide(); 
	}
}

The second, I don't think you loaded the fx right and again tried to play it on an array.
