I re-wrote the script to be much shorter, and more flexible. I'm not trying to step on your toes, or 1-up you or anything like that. Just figured this might help, especially if you are busy and I know you've mentioned updating the script anyways, so maybe this will save you the trouble. If you don't use it that's fine also, no offense taken. I'm not the best scripter, but pretty decent I believe, lol. Here it is.

//Follow the same steps in the tutorial, 
//except name all the triggers shootable_trig, 
//and don't add numbers to them. 
//Then make each trigger target it's bottle by selecting the trigger first, 
//then select the bottle, hit W in radiant to link them.
//Now you can place as many of these as you want, without having to change anything in script.
//Let's get them all as an array 
//instead of writing a seperate function for each bottle, and with no 'while()' loops eating memory

function init()
{
	trigs = GetEntArray("shootable_trig", "targetname");
	level.shootablesNeeded = trigs.size;
	level.shootablesCollected = 0;
    
	foreach(trig in trigs)
        {
    	    trig SetHintString("");
    	    trig SetCursorHint("HINT_NOICON");
    	    trig.bottle = GetEnt(trig.target, "targetname");
    	    trig thread trig_wait();
        }
}

function trig_wait()
{
	self waittill("trigger");
	self.bottle Delete();
	level.shootablesCollected++;
	if(level.shootablesCollected >= level.shootablesNeeded)
	{
		level thread reward();
	}
	IPrintLnBold("Shootables collected = ["+level.shootablesCollected+"]");
}

function reward()
{
	IPrintLnBold("Reward given");
	//insert reward code here
}

No problem   

leonardo745, looking back at your original code, I noticed you weren't getting the trigger using

trig_1 getEnt("whatever", "targetname");

so the game never knew what trigger it was looking for

    trig_1 = GetEnt("trig_shootable", "targetname");
    trig_1 SetHintString("");
    trig_1 SetCursorHint("HINT_NOICON");
    level.etapas = 0;
    correctweapon = GetWeapon("tesla_gun");

    while(1)
    {
    	trig_1 waittill("trigger", player);
    	usingweapon = player GetCurrentWeapon();
    	if(level.powerstatus >= level.poweron)
    	{
    		if(usingweapon == correctweapon)
    		{
       			        playfx(level._effect["powerup_grabbed"] ,GetEnt("trig_shootable","targetname").origin);

				playfx(level._effect["elec_transformer_rod"] ,(-228, -1111, 116), (0,0,0));
 				playfx(level._effect["elec_transformer_rod"] ,(-249, -1098, 116), (0,0,0));
 				playfx(level._effect["elec_transformer_rod"] ,(-269, -1086, 116), (0,0,0));

 				playfx(level._effect["elec_transformer_fx"] ,(-232, -1069, 83), (35, 58 ,0));
 				//playfx(level._effect["elec_transformer_fx"] ,GetEnt("elec_transformer_1","targetname").angles);
 				
 			}
    	}
    } 

Well, I stumbled upon this topic while searching through the help section. Hope this helps

someone in the topic mentioned that it worked for them.

you might need to use this

weapon = getWeapon("tesla_gun");

• are you getting errors while linking your scripts?
• Have you done all the necessary steps to make those fx play?

I can't really test anything at the moment because my game won't open

weapon = getWeapon("tesla_gun");

You can check what gun they have using getCurrentWeapon() and if the current weapon is the tesla_gun, you can do whatever you want after that.

while(1)
    {
    	trig_1 waittill("trigger", player);
    	current_weapon = player GetCurrentWeapon();
    	if(current_weapon == "tesla_gun")
    	{   		       
       		        playfx(level._effect["powerup_grabbed"] ,GetEnt("trig_shootable","targetname").origin);
			playfx(level._effect["elec_transformer_rod"] ,GetEnt("transformer_rod_7","targetname").origin);
 			playfx(level._effect["elec_transformer_rod"] ,GetEnt("transformer_rod_8","targetname").origin);
 			playfx(level._effect["elec_transformer_rod"] ,GetEnt("transformer_rod_9","targetname").origin);
 			playfx(level._effect["elec_transformer_fx"] ,GetEnt("elec_transformer_1","targetname").origin);
 		}
    }
