[VSCRIPT] Real Time Common Infected & Witches

DESCRIPTION

This V-SCRIPT tweaks several core parameters of all common infected and witches, which share the same AI (nextbots). The script enables infected to update continuously rather than every 0.100 ms as in vanilla, ensuring that players with 0.0 lerp won’t experience lagging or teleporting common infected.

This will negatively affect the performance of the host. Setting the refresh rate to 0.0 ms requires the host to use more resources because it needs to process updates faster than if it were set to 0.100 ms. Although on a mid-range or high-end computer the impact is minor, almost not noticeable, it is likely that Valve has limited this frequency thinking about older computers, from around 2008-2009.

FEATURES
• Continuous AI updates for Commons & Witches (No Special Infected)
• Smoother commons and witches for low-lerp players
• Prevents zombies from moving back and forth during attacks, which was causing players to miss their melee swings in some occasions.
• Improves hitbox positioning accuracy, making CI & Witches appear closer to where they actually are.
• Increased zombie stacking to a range of 16, allowing for tighter clustering without causing them to push each other.
• Makes the game harder, since commons get more frequent updates and behave more “smarter”.

¡THIS IS FOR LOCAL SERVERS, not for Official Dedicated Servers!

Known Bugs:

• If you set sv_cheats to 1, the update frequency will reset to default values (0.100 ms)

• With high update frequency, commons can get stuck when trying to climb cars or some surfaces, or else they can also get stuck and crouched on some tables or low places. (Tables at c1m3_mall, alarm event, cars and surfaces in c2m1_highway) For now I know that you can multiply the probability of this error occurring by using high tickrates, and since vanilla has 30 ticks, it has a low chance of occurring. Currently, there is no patch for this in VScript, but there are various solutions available with SourceMod See below for more information.

• If you're interested in which convars this changes, maybe to use in your server with sm_cvar, see below.

• How frequently nextbots are updated (lower = more frequent updates, default is 0.1).
nb_update_frequency 0.0

• Maximum number of nextbots updated per frame (default is 15).
nb_update_framelimit 100

• Reduces delay between nextbot updates.
nb_update_maxslide 0

• Forward friction (prevents them from moving back and forth evading melee attacks) (i think this affects the most at high tickrates).
nb_friction_forward 0

• Sideways friction; helps prevent infected from sliding when turning corners. (Thanks Melon for This)
nb_friction_sideways 10

• Maximum detection range between common infected. (to prevent them pushing eachother in a horde, bile, incapped, etc) ( i added this because somehow, more updates broke the vanilla clustering so i manually forced it similar to vanilla).
z_max_neighbor_range 16

• Rotation speed of common infected & witches (higher = faster turning). (added so witches turn faster when you try to melee them from the back and repeatedly jump to evade her attacks).
nb_yaw_rate 800

• I... seriously don't know why cl_interp_ratio exists...
It divides (cl_interp_ratio / cl_updaterate), but why?! you can't set 0.0 lerps because of this ♥♥♥♥.
only if you set your cl_updaterate to something like 30 000 then it will divide by that high number and give you 0.0 lerp
I mean, it's not even needed anymore anyway.
sv_client_min_interp_ratio -1
sv_client_max_interp_ratio 0
