[VSCRIPT] Real Time Common Infected

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 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.
• Increased zombie stacking to a range of 16, allowing for tighter clustering without causing them to push each other.

¡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.

• For Sourcemod Users, i recommend the below plugins

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

-- Sets the NPC update frequency.
nb_update_frequency 0.0

-- Frame limit for NPC updates.
nb_update_framelimit 100

-- Maximum slide for NPC updates.
nb_update_maxslide 0

-- Sets the forward friction for NPCs. (to prevent them moving back and forth at high tickrates.)
nb_friction_forward 0

-- Sets the sideway friction for NPCs. (to prevent them sliding around like ice when turning in 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)
z_max_neighbor_range 16

-- Forced Lerp Values, as high values are not needed anymore.
sv_client_min_interp_ratio -1
sv_client_max_interp_ratio 0
