this will play an animated lightning like effect on your perk icons after buying them. this may need to be adjusted if you changed the location the icons show up at

first open up your maps _zombiemode.gsc and at the very bottom place this:

electro_perk_start()
{
players = get_players();
	for( i = 0; i < players.size; i++ )
	{
	players[i] thread electro_perk();
	}
}

electro_perk()//plays hud fx on buying a perk (bo3 style)
{
while (1)
{
	if ( !IsDefined( self.perk_hud ) )
	{
		self.perk_hud = [];
	}

self.perv = self.perk_hud.size;
wait .1;
self.perv2 = self.perk_hud.size;
if (self.perv2  > self.perv )
self thread lightning_zap();
}
}

lightning_zap()
{
	self endon( "disconnect" ); 
	self endon("death");
 
	wait 0.05;
	hud = create_simple_hud( self );
	hud.foreground = true; 
	hud.sort = 1; 
	hud.hidewheninmenu = false; 
	hud.alignX = "left"; 
	hud.alignY = "bottom";
	hud.horzAlign = "left"; 
	hud.vertAlign = "bottom";
	hud.x = self.perk_hud.size * 30 - 30; 
	hud.y = hud.y - 70; 
	hud.alpha = 1;
	wait .1;
	while (hud.alpha > 0){
		for(i=1;i<4;i++){
			hud SetShader( "electro"+i, 24, 24 );
			wait .1;
		}
		hud.alpha -= 0.25;
	}
	hud destroy_hud();
}

then near the top under:

init_flags();

place:

	PrecacheShader( "electro1" );
	PrecacheShader( "electro2" );
	PrecacheShader( "electro3" );
	PrecacheShader( "electro4" );

then under :

	level thread players_playing();

place:

	level thread electro_perk_start();

your now done with that file, save and close it

now if you already havent done so, move the contains of the file (the one from the link at the top) to where they need to be and add this to your mod.csv:

material,electro1
material,electro2
material,electro3
material,electro4

that should be it, have fun and credit if used

note: i have not tested to work with harrybo21's perks, however it should be fine (tell me if not and i'll make a version for that )

Could you upload a pic would like to see what it looks like ^^

theres a video, i thought an image wouldnt really work since it needs to be animated, i can still do that though

Could do a GIF, Gyazo has this ability.

Looks really nice though.

Nice Man , cool little feature to add

Dude how come in every script I see from you, you define the temporary variables on the player? Like self.perv and self.perv2, why define that on the player? Maybe someone else uses those variable names. Just take the "self." Off. Same with the hud. Just define it zap_hud or something but why did you define it on the player? And why did you make an array for it when it's only one hud with one key?

Calm down, lol, if he made mistakes you don't have to be a dick about it. He appears to be doing a good job at learning and I commend him on helping the community while he is, if you want help him better to do it without "I know it all and you should too" attitude.

This is interesting, I've never seen 'animated' hud elements before, this could be used for lots of things +1.

awesome

i'm constantly finding out about new scripting stuff, so theres quite a few gaps in my knowledge about this stuff, i learned the basics of hud elements (besides just adding new ones, like perk icons) only just over a week ago, of which i've taught myself from looking at treyarch's scripts (which is where i usually learn from)

I'm not trying to be a dick or anything, I am just saying if there is a variable that only is defined that one time in that one function, you do not need to define it on something else. And if you are going to define something on a player, make it something more specific than "perv". And the only reason I point it out is because you did not used to do it before.

can be done pretty easily but the trade off is we need to use a material per "frame" for it. so will destroy your material count if you did it a lot. This is ok, only 5 extra materials

I was going to do this for vultures stink but was too lazy


as for the argument, it really makes no difference, so no idea why your arguing about it...

Yes it "could" be used by someone else, but likely not, and would take like 1 minute to identify anyway...

there is no "right way", its all preference ( so long as he is remembering to clear the variables )

If he wanted he could just "prefix" then there will never be a mixup. ie self.dr_variable1 =

yeah, animation (at least this way) isnt hard, its just you cant use it too much cause theres a hud limit and a Precache limit (ive hit this limits at least three times in my wip as it is)
also this does only use one hud spot but you dont have to add much to hit the limit,i think with the stock hud you can add up to around 15-18 things and perk icons take up those spots

are you sure this isnt going to appear for "everyone"?

Should be using a "client" hud element? Unless create_simple_hud( PERSON ) does that, but im not sure it does asi went through this with hintstrings once

Also i didnt know there was a precache limit, what error did it give?

it was defined as self so i think it goes for just the one player, i should check that actually, and i dont remember the erroe but i remember it only showed up in co-op for some reason, i'll check my error log and see if i can still find it, if not i'll uncomment my unused precaches to make it show up again
