client_buy Forward



.: Description :.


The plugin offers a forward that allow you to hook any buy attempt.



.: Forward :.

client_buy < player index > < item type >

Returns : PLUGIN_CONTINUE , PLUGIN_HANDLED


.: Item indexes :.

For weapons, index is the weapon type, so CSW_AK47 or CSW_MP5NAVY for example.
For vest and helmet, this is amxx defines : CSW_VEST and CSW_VESTHELM.
I had to introduce new indexes for the plugin, here they are :
  • CSW_DEFUSER : defusal kit
  • CSW_NVGS : nightvision
  • CSW_SHIELD : shield
  • CSW_PRIMAMMO : primary ammo
  • CSW_SECAMMO : secondary ammo

Since it's always interesting to show severals ways of something, I post just another way using Orpheu. No harcoding. Also, to piss Connor off.

PHP Code:
#include <amxmodx>
#include <orpheu>
#include <fakemeta>

enum
{
    
CSW_DEFUSER 33,
    
CSW_NVGS,
    
CSW_SHIELD,
    
CSW_PRIMAMMO,
    
CSW_SECAMMO
};

const 
BitsPistols = ( << CSW_GLOCK18 << CSW_USP << CSW_P228 << CSW_DEAGLE << CSW_ELITE << CSW_FIVESEVEN );

new const 
itemSlotToWeaponId[] = { -1CSW_VESTCSW_VESTHELMCSW_FLASHBANGCSW_HEGRENADECSW_SMOKEGRENADECSW_NVGSCSW_DEFUSERCSW_SHIELD };
new const 
ammoToWeaponId    [] = { CSW_PRIMAMMOCSW_SECAMMO };

const 
m_iId 43;

new 
HandleForwardBuy;

public 
plugin_natives()
{
    
register_library"cl_buy" );
}

public 
plugin_init()
{
    
register_plugin"Can Buy Item""1.0.0""Arkshine" );

    
OrpheuRegisterHookOrpheuGetFunction"CanBuyThis" ), "CanBuyThis" ); // Weapons
    
OrpheuRegisterHookOrpheuGetFunction"BuyItem" )   , "BuyItem"    ); // Items
    
OrpheuRegisterHookOrpheuGetFunction"BuyGunAmmo" ), "BuyGunAmmo" ); // Ammos
    
    
HandleForwardBuy CreateMultiForward"client_buy"ET_STOPFP_CELLFP_CELL );
}

public 
OrpheuHookReturn:CanBuyThis( const player, const weaponId )
{
    return 
CanBuyItemplayerweaponId );
}

public 
OrpheuHookReturn:BuyItem( const player, const slot )
{
    return 
CanBuyItemplayeritemSlotToWeaponIdslot ] );
}

public 
OrpheuHookReturn:BuyGunAmmo( const player, const item, const bool:displayMsg )
{
    return 
CanBuyItemplayerammoToWeaponId[ !( get_pdata_intitemm_iId) & BitsPistols ) ] );
}

OrpheuHookReturn:CanBuyItem( const player, const itemId )
{
    static 
pluginReturn;
    
ExecuteForwardHandleForwardBuypluginReturnplayeritemId );

    return ( 
pluginReturn != PLUGIN_CONTINUE ) ? OrpheuSupercede OrpheuIgnored;

Plugin not really tested. I won't develop more, it was just to see how it can be handled with orpheu. Feel free to Connor to do what he wants with it.

Signatures attached.

Isn't the right section. And if you do not understand, you don't need to show like that this forward is bad for you. (meant your smile, yes)
