[L4D/L4D2]WeaponHanding_API

[MYGO.pl]

Hello, WeaponHanding API is a group of hooks to scale handing speeds of weapons with a multiplier with forwards.

Little project i'v been working on for a while, hope you like.

Thanks:

Timocop: Using some code of your code.
Silvers: Helping with stupid moments and advice.
smlib: Thanks for smlib code and all contributors.
DHooks: Thanks Peace-Maker & Dr!fter
SM Dev team!

Convars These are for you,
I made some fixes and changes to weapon handling, by default all of turned off, besides deploy modifier animation speed which valve forgot implement in their code e.g. in vanilla single pistol DeployDuration is a "0.5" modifier which is 2x faster than the animation shows.

PHP Code:

---

// 1 = (match deploy speed animation to the "DeployDuration" keyvalue in weapon_*.txt) 0 = (ignore "DeployDuration" keyvalue in weapon_*.txt and matches deploy speed to animation speed) before being modified
// -
// Default: "1"
// Minimum: "0.000000"
// Maximum: "1.000000"
wh_deploy_animation_speed "1"

// 1 = (double pistol shoot at double speed of a single pistol 2~ shots persec slower than vanilla) 0 = (keeps vanilla cycle rate of 0.075) before being modified
// -
// Default: "0"
// Minimum: "0.000000"
// Maximum: "1.000000"
wh_double_pistol_cycle_rate "0"

// 1 = (use "survivor_incapacitated_cycle_time" for incap shooting cycle rate) 0 = (ignores the cvar and uses weapon_*.txt cycle rates) before being modified
// -
// Default: "1"
// Minimum: "0.000000"
// Maximum: "1.000000"
wh_use_incap_cycle_cvar "1"

// 1 = (use "survivor_incapacitated_reload_multiplier" for incap reloading cycle rate) 0 = (ignores the cvar and uses default reload cycle rates) before being modified
// -
// Default: "1"
// Minimum: "0.000000"
// Maximum: "1.000000"
wh_use_incap_reload_cycle_cvar "1"

WeaponHandling API has forwards for OnReloading, OnShooting, OnDeploy, OnMeleeSwing and OnThrowingThrowable, these are not proper forward names those are documented in the include file.

Little history:

I needed something that was direct(is not reliant on events, events are usually after game actions) for modifying weapon handling stats that can eliminate cross plugin issues without too much work.

One of the common issues with speeding up reloading is awful animation issues of double reload,
this is because of internal timer for the reload finish timer, OnReloadModifier is called twice for reload modifier which we can change with entprops, second OnReloadFinish we cannot,
not really looked into too much likely a countdown time.

This will not beable to correct animation issues caused by prediction errors, since this is all server sided and latency is a thing!

Include notes

Spoiler

1. I'v included some useful stocks for performance friendly string checking of weapon classnames in l4d1 & 2 to output enum value.

2. L4D1 Pills use speed is not functional, is different to L4D2, L4D1 pills use speed looks to be in CPainPills::PrimaryAttack
but I could not figure out how to read the countdown timer to change it, maybe someone else knows yes I used l4d2d_timers.inc and tried some stuff my self don't wanna read :(.

3. These forwards are likely not safe to do much to clients in e.g. change weapon, stagger them, kill them, ect,
this is due to where parts are hooked and the game expects that kind of stuff later in post think ect.

4. Weapon SG552 firerate while zooming is "0.13500001",
to detect if someone is zoomed with the weapon check the FOV entprops which is what this function does CTerrorGun::IsOwnerZoomed.

5. I tried to support l4d1 best I can, hope you like them :D
