Skully's Zombie Collision[/h1][h3]A mod that adds proper collision between zombies, preventing them from phasing through each other while chasing the player.

Internally tested and balanced. Reported by other players to work in multiplayer for extended sessions without issues (see comments for feedback). [hr][/hr]

The issue:

In vanilla, zombies usually go through one another when they are chasing you, especially if you hit or push the zombie at the front.

[hr][/hr]

The solution:

This mod aims to fix the lack of collision that zombies have when they are chasing the player in a way that doesn't ruin your performance. It only considers the zombies close to you and only a small amount, which is what matters. Whether you have 10 zombies or 100 zombies around you, the additional performance strain remains roughly the same.

Multiplayer tested:

(With 200 ping and the usual MP desync. When fighting alone, feels like in single player)

Shoutout to goco for helping me test, much apreciated [hr][/hr]

Zombies dont go through walls!

Tried a new logic for the zombie displacement and tried some optimization methods

Testing Results

My testing, on my own medium-high end gaming PC, showed that there is little impact on the addition of the mod. At the highest sandbox settings, with 50 zombies in a cramped space, CPU usage, and FPS were not impacted by any considerable margin compared to vanilla zomboid. This does not mean that less powerfull PCs will have the same percentage impact, you should test the mod by itself vs vanilla on your rig, and not on a 500+ modlist where something else might be the culprit. I dont have my old rig set up to test and record, would be a hassle just to test a mod lol.

Now with sandbox settings, translated for 11 languaged (With AI)

Its currently balanced. But if anyone wants to change any setting be it for collision size or less collisions, I recommend downloading a sandbox config editor mod, and testing in single player to find a good balance to your liking, since it requires a reload each time you change [hr][/hr]

  • Safe to add and remove midgame
  • Should be compatible with most mods
  • Works in MP according to commenters
  • I'll make a list of incompatibilities if any come up

Recommended Mods:

Tripping zombies, for people who want zombies to trip when bumping [hr][/hr]
