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
