class Weapon

Both coordinates are from objects in the decompiled scripts.

Native related to _0xECDC202B25E5CF48 p1 value. The only weapon hash used in the decompiled scripts is weapon_air_defence_gun. These two natives are used by the yacht script, decompiled scripts suggest it and the weapon hash used (valkyrie's rockets) are also used by yachts.

Returns the base/default ammo type of the specified ped's specified weapon.

Use GET_PED_AMMO_TYPE_FROM_WEAPON if you want current ammo type (like AMMO_MG_INCENDIARY/AMMO_MG_TRACER while using MkII magazines) and use this if you want base ammo type. (AMMO_MG)

Does the same as _SET_CAN_PED_SELECT_WEAPON except for all weapons.

Disables selecting the given weapon. Ped isn't forced to put the gun away. However you can't reselect the weapon if you holster then unholster. Weapon is also grayed out on the weapon wheel.

Enables/disables flashlight on ped's weapon.

NativeDB Introduced: v2060

Changes the weapon damage output by the given multiplier value. Does NOT need to be called every frame.

NativeDB Introduced: v2372

this returns if you can use the weapon while using a parachute  

Does NOT seem to work with HAS_PED_BEEN_DAMAGED_BY_WEAPON. Use CLEAR_ENTITY_LAST_WEAPON_DAMAGE and HAS_ENTITY_BEEN_DAMAGED_BY_WEAPON instead.

Create a weapon object that cannot be attached to a ped. If you want to create a weapon object that can be attached to a ped, use CREATE_OBJECT instead.

NativeDB Added Parameter 9: BOOL bRegisterAsNetworkObject
NativeDB Added Parameter 10: BOOL bScriptHostObject

Enables laser sight on any weapon.  
It doesn't work. Neither on tick nor OnKeyDown  

WEAPON::EXPLODE_PROJECTILES(PLAYER::PLAYER_PED_ID(), func_221(0x00000003), 0x00000001);  

WEAPON::GET_AMMO_IN_PED_WEAPON(PLAYER::PLAYER_PED_ID(), a_0)  
From decompiled scripts  
Returns total ammo in weapon  
GTALua Example :  
natives.WEAPON.GET_AMMO_IN_PED_WEAPON(plyPed, WeaponHash)  

The return value seems to indicate returns true if the hash of the weapon object weapon equals the weapon hash.  
p2 seems to be 1 most of the time; and is not implemented.

NativeDB Added Parameter 2: Any p1

gadgetHash - was always 0xFBAB5776 ("GADGET_PARACHUTE").  

p2 is mostly 1 in the scripts.  

Returns the current ammo type of the specified ped's specified weapon.

MkII magazines will change the return value, like Pistol MkII returning AMMO_PISTOL without any components and returning AMMO_PISTOL_TRACER after Tracer Rounds component is attached.

Use 0xF489B44DD5AF4BD9 if you always want AMMO_PISTOL.

Pass ped. Pass address of Vector3.  
The coord will be put into the Vector3.  
The return will determine whether there was a coord found or not.  

// Returns the size of the default weapon component clip.  
Use it like this:  
char cClipSize[32];  
Hash cur;  
if (WEAPON::GET_CURRENT_PED_WEAPON(playerPed, &cur, 1))  
{  
    if (WEAPON::IS_WEAPON_VALID(cur))  
    {  
        int iClipSize = WEAPON::GET_WEAPON_CLIP_SIZE(cur);  
        sprintf_s(cClipSize, "ClipSize: %.d", iClipSize);  
        vDrawString(cClipSize, 0.5f, 0.5f);  
    }  
}  

This native does not return damages of weapons from the melee and explosive group.

0=unknown (or incorrect weaponHash)  
1= no damage (flare,snowball, petrolcan)  
2=melee  
3=bullet  
4=force ragdoll fall  
5=explosive (RPG, Railgun, grenade)  
6=fire(molotov)  
8=fall(WEAPON_HELI_CRASH)  
10=electric  
11=barbed wire  
12=extinguisher  
13=gas  
14=water cannon(WEAPON_HIT_BY_WATER_CANNON)  

// members should be aligned to 8 bytes by default but it's best to use alignas here, just to be sure  
struct WeaponHudStatsData  
{  
	alignas(8) uint8_t hudDamage; // 0x0000  
	alignas(8) uint8_t hudSpeed; // 0x0008  
	alignas(8) uint8_t hudCapacity; // 0x0010  
	alignas(8) uint8_t hudAccuracy; // 0x0018  
	alignas(8) uint8_t hudRange; // 0x0020  
};  
Usage:  
WeaponHudStatsData data;  
if (GET_WEAPON_HUD_STATS(weaponHash, (Any*)&data))  
{  
    // uint8_t damagePercentage = data.hudDamage etc...  
}  

Drops the current weapon and returns the object  
Unknown behavior when unarmed.  

Gets and returns the hash of the group of the specified weapon (group names can be found/changed under "Group" in the weapons' meta file). Note that the group is not the same as the location on the weapon wheel.

Returns the model of any weapon.  
Can also take an ammo hash?  
sub_6663a(&l_115B, WEAPON::GET_WEAPONTYPE_MODEL(${ammo_rpg}));  

Gives a weapon to PED with a delay, example:
WEAPON::GIVE_DELAYED_WEAPON_TO_PED(PED::PLAYER_PED_ID(), MISC::GET_HASH_KEY("WEAPON_PISTOL"), 1000, false)

addonHash:
(use WEAPON::GET_WEAPON_COMPONENT_TYPE_MODEL() to get hash value)
${component_at_ar_flsh}, ${component_at_ar_supp}, ${component_at_pi_flsh}, ${component_at_scope_large}, ${component_at_ar_supp_02}

It determines what weapons caused damage:
If you want to define only a specific weapon, second parameter=weapon hash code, third parameter=0
If you want to define any melee weapon, second parameter=0, third parameter=1.
If you want to identify any weapon (firearms, melee, rockets, etc.), second parameter=0, third parameter=2.

It determines what weapons caused damage:  
If you want to define only a specific weapon, second parameter=weapon hash code, third parameter=0  
If you want to define any melee weapon, second parameter=0, third parameter=1.  
If you want to identify any weapon (firearms, melee, rockets, etc.), second parameter=0, third parameter=2.  

p2 should be FALSE, otherwise it seems to always return FALSE  
Bool does not check if the weapon is current equipped, unfortunately.  

Third Parameter = unsure, but pretty sure it is weapon hash  
--> get_hash_key("weapon_stickybomb")  
Fourth Parameter = unsure, almost always -1  

Hides the players weapon during a cutscene.  

Checks if the ped is currently equipped with a weapon matching a bit specified using a bitwise-or in typeFlags.

This native returns a true or false value.  
Ped ped = The ped whose weapon you want to check.  

Forces a ped to reload only if they are able to; if they have a full magazine, they will not reload.

Parameter p1 does not seem to be used or referenced in game binaries.\

 * **Note:** When called for networked entities, a `CRemoveAllWeaponsEvent` will be created per request.

If explode true, then removal is done through exploding the projectile. Basically the same as EXPLODE_PROJECTILES but without defining the owner ped.

This native removes a specified weapon from your selected ped.  
Weapon Hashes: pastebin.com/0wwDZgkF  
Example:  
C#:  
Function.Call(Hash.REMOVE_WEAPON_FROM_PED, Game.Player.Character, 0x99B507EA);  
C++:  
WEAPON::REMOVE_WEAPON_FROM_PED(PLAYER::PLAYER_PED_ID(), 0x99B507EA);  
The code above removes the knife from the player.  

Nearly every instance of p1 I found was 31. Nearly every instance of p2 I found was 0.  
REQUEST_WEAPON_ASSET(iLocal_1888, 31, 26);  

NativeDB Added Parameter 4: BOOL p3

Has 5 parameters since latest patches.  

p1/gadgetHash was always 0xFBAB5776 ("GADGET_PARACHUTE").  
p2 is always true.  

Returns handle of the projectile.

Changes the selected ped aiming animation style, you can find the list of animations below.

These are stored in the weaponanimations.meta file located in Grand Theft Auto V\update\update.rpf\common\data\ai\weaponanimations.meta.

For Lua, it's best if you send the animation using compile-time jenkins hashes to avoid overhead. An example is shown down below.
