Implement RH_SV_SendResources hook

[ShadowsAdi]

Useful to create a custom resource list when requested by a client or to allow multiple download url setup.

Example:

/* Sublime AMXX Editor v4.2 */

#include <amxmodx>
#include <reapi>
#include <geoip>

new g_pCvar
new g_szCvar[64]

public plugin_init()
{
	RegisterHookChain(RH_SV_SendResources, "RH_SV_SendResources_Pre")
	RegisterHookChain(RH_SV_SendResources, "RH_SV_SendResources_Post", 1)
}

public plugin_precache()
{
	server_cmd("exec server.cfg")
	server_exec()

	g_pCvar = get_cvar_pointer("sv_downloadurl")
	get_pcvar_string(g_pCvar, g_szCvar, charsmax(g_szCvar))
}

public RH_SV_SendResources_Post()
{
	RequestFrame("SV_SendResFrame")
}

public SV_SendResFrame()
{
	new szCvar[64]
	set_pcvar_string(g_pCvar, g_szCvar)
	get_pcvar_string(g_pCvar, szCvar, charsmax(szCvar))
}

public RH_SV_SendResources_Pre()
{
	new szIP[18], szRez[3], szCvar[64]
	rh_get_net_from(szIP, charsmax(szIP))

	geoip_code2_ex(szIP, szRez)

	if(equali(szRez, "RO"))
	{
		set_pcvar_string(g_pCvar, "test.com")
		get_pcvar_string(g_pCvar, szCvar, charsmax(szCvar))
	}
}
