AI Difficulty System

What is this?

This is the brand new system that allows to tweak settings related to zeds through server configs "on fly", and that way create various difficulty presets.

Its main difference from other solutions is that it doesn't natively modify zed pawns, but rather allows to quickly configure their parameters through a server-side INI-file.

Currently the system is limited to custom zed parameters, but in future it will be expanded with few other mechanics, such as different effects based on damage type, zonal hit system for players and stuff like that.

Apart from that, it includes custom behaviour and stages of the bosses, generally making them harder.

All changes are organised into difficulty presets that can be switched back and forth during a match:

  • !dcad set to false enables the sytem, allowing to use custom zed presets;

  • !ad <index> switches between difficulty presets.

Available Presets

There are few presets of zeds defined by their index:

  • 0 - Vanilla Zeds;

  • 1 - Pivo Zeds;

  • 2 - Harder Zeds by Kore;

  • 3 - Nightcore Zeds by fanta.

Please note that all listed options are only available on Precision/HoE+ servers, while Vanilla has only 1 and 2.

Note

There is another parameter in Harder and Nightcore zeds called Low Intensity Attack Scale of Fireball Interval, however it is not used because Game Conductor is disabled on both HoE+ and CD, therefore this parameter is obsolete.

Same with the Elite Pawns (EDARs) which are natively disabled on HoE+/Precision servers.
