CVAR Pointers

CVAR pointers are a new method of getting/retrieving CVAR values. It is a much faster method than using the get/set_cvar functions. The difference is instead of passing a "cvar name", you pass the "cvar pointer", which is a direct memory access rather than a string lookup. In order to easily accomodate this, register_cvar now returns a CVAR pointer from the CVAR you created. You can also use get_cvar_pointer. Usage is mapped as such:

• get_cvar_flags -> get_pcvar_flags
• set_cvar_flags -> set_pcvar_flags
• get_cvar_string -> get_pcvar_string
• set_cvar_string -> NONE (not implemented)
• get_cvar_num -> get_pcvar_num
• set_cvar_num -> set_pcvar_num
• get_cvar_float -> get_pcvar_float

An example of old code might be:

#include <amxmodx>
 
public plugin_init()
{
   register_cvar("csdm_active", "1")
}
 
public pfn_touch()
{
   if (!get_cvar_num("csdm_active"))
      return PLUGIN_CONTINUE
}

To use CVAR pointers and optimize your code:

#include <amxmodx>
 
new g_csdm_active
 
public plugin_init()
{
   g_csdm_active = register_cvar("csdm_active", "1")
}
 
public pfn_touch()
{
   if (!get_pcvar_num(g_csdm_active))
      return PLUGIN_CONTINUE
}
