g[s]et_cvar and g[s]et_pcvar

in general which is better to use?

i know that as of 1.80 g[s]et_pcvar has all the functions as g[s]et_cvar so this should not be a factor

g[s]et_pcvar is a pointer for cvars and is much faster!

Re: g[s]et_cvar and g[s]et_pcvar

yes i know it is faster but for that speed you are sacrificing memory, or at least that is what ive read.

okay lets put it this way.
i kno that if u use it for multiple functions then pcvar is the way to go but is it better than using cvar with 1 function?

which example is better?:

PHP Code:


		
			
new test_pcvar

public plugin_init()
{
    register_plugin("test", "", "")
    test_pcvar = register_cvar("amx_test_cvar", "1")
}

public client_putinserver(id)
{
    if (get_pcvar_num(test_pcvar))
        client_print(0, print_chat, "test")
}

PHP Code:


		
			
public plugin_init()
{
    register_plugin("test", "", "")
    register_cvar("amx_test_cvar", "1")
}

public client_putinserver(id)
{
    if (get_cvar_num("amx_test_cvar"))
        client_print(0, print_chat, "test")
}

The first one.

if you really wanted to optimize it, you could just do:

Code:

public plugin_init()

{

    register_plugin("test", "", "")

}



public client_putinserver(id)

{

    static test_pcvar;

    if( !test_pcvar )

        test_pcvar = register_cvar("amx_test_cvar", "1")

    if (get_pcvar_num(test_pcvar))

        client_print(0, print_chat, "test")

}

        client_print(0, print_chat, "test")

}

thats not better.

memory usage to his pcvar example: identical
performance: worst. you check everytime in client_putinserver if the cvar is registered which will cost performance(not much, but it costs performance).

I've said this before and I'll say it again:
You should allways optimize for speed rather than memory consumption.

Re: g[s]et_cvar and g[s]et_pcvar

does the speed much that much of a difference?
