[CAS Mechanism] Realistic Reloading Mechanism

[CAS Mechanism] Realistic Reloading Mechanism

CAS Realistic Reloading Mechanism

Warning: This mechanism conflicts with the Normal Magazine Mechanism. Do not enable both at the same time.

This is a Mechanism Pack for the Custom Accessory System.

It adds realistic magazine, chambered-round, magazine capacity, and reload speed behavior for CAS-compatible weapons.

Required Add-on

• CAS Core

Recommended Add-on

• CAS Base Magazine Pack

This add-on only provides the mechanism.

Install a CAS-compatible Magazine Data Pack to get actual magazine accessories.

Main Features

• Tracks real ammunition remaining in the current magazine
• Supports chambered rounds
• Supports open-bolt and closed-bolt weapons
• Supports magazine capacity multipliers
• Supports reload speed multipliers
• Supports reduced-capacity magazines and large drums
• Prevents discarded magazine rounds from automatically returning to reserve ammo
• Uses a lightweight thinker only while reload work is pending

Realistic Reloading

The mechanism tracks the actual rounds remaining inside the loaded magazine.

When you reload, ammunition left inside the removed magazine is treated as real magazine ammunition and is not automatically returned to normal reserve ammo.

Closed-bolt weapons may retain one chambered round.

Open-bolt weapons do not receive an additional chambered round.

Supported CAS Properties

cas_ammo_capacity

cas_ammo_capacity[/code]

Controls magazine capacity using a strict multiplier.

[code]
0.50 = 50% capacity
0.75 = 75% capacity
1.00 = original capacity
1.30 = 130% capacity
1.50 = 150% capacity
2.50 = 250% capacity

Calculation:

target capacity =
ceil(original capacity × cas_ammo_capacity)

Example:

Original capacity = 40
cas_ammo_capacity = 1.50

40 × 1.50 = 60

Values below 1.00 reduce capacity.

Values above 1.00 increase capacity.

Values above 2.00 are normal multipliers and can be used for large drums.

There is no legacy absolute-capacity interpretation.

There is also no automatic conversion from 0.xx to 1.xx.

cas_reload_speed_multi

cas_reload_speed_multi[/code]

Controls reload speed.

[code]
1.35 = 35% faster
1.20 = 20% faster
1.00 = original speed
0.85 = 15% slower

is_open_bolt

Optional compatibility property:

1 = open bolt
0 = closed bolt

Open-Bolt Config

The mechanism generates:

left4dead2/ems/custom_accessory_system/magazine_open_bolt.txt

Example:

weapon_smg=1
weapon_smg_silenced=1
weapon_smg_mp5=0
weapon_rifle=0
weapon_rifle_ak47=0
weapon_rifle_m60=1

1 = open bolt
0 = closed bolt

By default, SMG, Silenced SMG, and M60 are treated as open-bolt weapons.

Other listed weapons are closed-bolt unless changed in the config.

Magazine Accessory Example

A compatible Data Pack can provide:

cas_ammo_capacity 1.50 key_op multi
cas_reload_speed_multi 0.90 key_op multi

This gives:

• 150% magazine capacity
• 90% reload speed

A quick extended magazine may use:

cas_ammo_capacity 1.30 key_op multi
cas_reload_speed_multi 1.20 key_op multi

Multiplier Stacking

Because magazine capacity uses [code]key_op multi[/code], compatible capacity modifiers can stack through CAS Core.

Example:

1.50 × 1.20 = 1.80

The final capacity becomes 180% of the original magazine size.

Weapon Notes

This mechanism is mainly intended for magazine-fed firearms.

Shotguns use shell-by-shell reload behavior and are not handled as normal detachable-magazine weapons.

Pistols use additional capacity handling where required.

Compatibility Notes

• Conflicts with the Normal Magazine Mechanism
• Do not enable both magazine mechanisms
• Requires CAS Core
• Does not add magazine accessories by itself
• cas_ammo_capacity uses strict multiplier semantics
• 0.50 means 50% capacity, not +50%
• 1.50 means +50% capacity
• Values above 2.00 remain normal multipliers
• New accessories should use key_op multi

Technical Notes

• Does not use EntFire timers
• Uses a lightweight thinker only while reload processing is pending
• Does not manually control viewmodel playback
• Does not modify m_flTimeWeaponIdle
• Does not modify m_flNextSecondaryAttack

Summary

CAS Core provides the framework.
