Maximizer Blake Great things Deserve the wait

Kyber66 Fixed

Xerxes which one

T.Re.Viento Makes sense now

Regarding the no running, I use the script in testing on every map and never had a no running issue, what round/step the zombie was supposed to run and it didn't?

WolflexZ They Respawn/Die if they have met certain conditions that I disabled here:
1 - Zombie is far away
2 - Zombie is Idle (he stands in place for too long)
I couldn't find anything related to needing to hit the player

As you said, many people don't need this script, and it might do them more harm then good, it's intended for some uses and not normal play.

T.Re.Viento Thanks for trying it, but I'm curious, why do you use it ?

yeah, Origins and Motd and some areas in other maps need the things I disable here for them to respawn the zombies, I can think of a way to make it work, but that isn't what I intended for the script, only thing you can do is only move out and in the crazy place if the rounds are changing.

Oh wow you are doing Perks too!
Thank you for doing it

works really well, Thanks for the work!

xNando compare your script with the one from the post above, see where you made a difference, I just tried the one in the post and it works

xNando hmm, did you just copy the script of origins?

every map has its own thing, some things are the same though

Update: All maps have been added, except Nuketown

JezuzLizard don't know how it works

xNando you can make on big replace func and add a check for each map so it auto loads from one script

or make a file for each map

I might do it later

iluisey each map has the same checks, it just a name change

replaceFunc(maps\mp\zm_tomb::tomb_round_spawn_failsafe, ::tomb_round_spawn_failsafe)
replaceFunc(maps\mp\zm_tomb_distance_tracking::delete_zombie_noone_looking, ::delete_zombie_noone_looking);

zm_tomb is orignis, zm_transit is for tranzit etc

Hello,

This is a simple script using replace function to cap the zombies numbers in a round to 1 player.
Now instead of 389 zombies for 4 players on round 26, it's now 84

You can also make it a X number of zombies for X number of players, all from the simple function, 8 players in game but only spawns zombies up to 6 players.

Or change how much zombies get added per player for better
calculating, example on round 40 for normal calculations:
1 Player: 168 Zombies
2 Players: 312 Zombies, 1.85 Worth of zombies
3 Players: 600 Zombies, 3.57 Worth of zombies
4 Players: 888 Zombies, 5.28 Worth of zombies

It's also possible to change the formula, you can have any number of zombies you want.

the change is simple:
From --->

if ( player_num == 1 )
        max = max + int( 0.5 * level.zombie_vars["zombie_ai_per_player"] * multiplier );
    else
	max = max + int( ( player_num - 1 ) * level.zombie_vars["zombie_ai_per_player"] * multiplier );

To --->

        max = max + int( 0.5 * level.zombie_vars["zombie_ai_per_player"] * multiplier );
    else

Hello,

In order to stop Zombies from dying by being Idle for too long & if they are far from you, you change these functions ( This is for Origins, Other maps should be the same by replacing the names and some don't use a function from this ), First Idle:

tomb_round_spawn_failsafe()//tomp is Origins name

replace OR comment out:

self dodamage( self.health + 100, ( 0, 0, 0 ) );
level.zombie_total++;
level.zombie_total_subtract++;

zombie_damage_failsafe()//this for damaged or missing limbs

replace OR comment out:

self.enemy dodamage( self.enemy.health + 1000, self.enemy.origin, self, self, "none", "MOD_RIFLE_BULLET" );
continue_failsafe_damage = 1;

for far away:

delete_zombie_noone_looking( how_close, how_high )//every map has this

replace OR comment out:

self notify( "zombie_delete" );
self delete();
level.zombie_total++;           level.zombie_respawned_health[level.zombie_respawned_health.size] = self.health;
