[L4D1 & L4D2] Remove Weapons/Carryables Collision [v1.0.6 | 17-September-2021]

Marttt · **Author**

Description

This plugin changes the collision from all weapons or carryables to collide only with the world and static stuff.

Useful on servers where is possible to have many items in almost the same place (e.g. through !buy system), which can cause lag because of the number of items colliding.

Features

Changes the collision for all weapons or carryables to collide only with the world and static stuff.
Allows disabling motion for all weapons or carryables on hit/shove.

Cvars

A configuration file named "l4d_remove_item_collision.cfg" will automatically be created for you upon the first run in the "\cfg\sourcemod\" folder.

Change Log

Spoiler

Notes

This plugin precache some models.
Collision Group (m_CollisionGroup) was changed to 2 (COLLISION_GROUP_DEBRIS_TRIGGER).
BUG: Using m_CollisionGroup = 1 (COLLISION_GROUP_DEBRIS), prevents prop_physics entities from being picked up, but weapon_* entities seems to work normal with m_CollisionGroup = 1.
Because of the new collision group, some items can be in the same place, looking as if it was just one.

To Do

Create specific config for each entity class.

Recommended Plugins

Use with [L4D & L4D2]Physics Object Pushfix[Left 4 Fix] plugin by Lux, to prevent props from moving when passing over them.

Not only. I saw a crash due to this type of collision caused due to some people by intention abusing grab/drop the weapon feature from the Silver's Guns Cabinet.

Hi, Marttt.

Plugin contains an incorrect check for the allowed game engine for L4D1.
Prevents plugin from loading.
