Cu aceste functii puteti sa testati care functie/nativa e mai eficienta/rapida, multumesc lui black rose, exemplu+functia in sine mai jos:
Code: Select all
#include <amxmodx>
#include <fun>
#include <fakemeta>
#define debug_start() tickcount()
#define debug_stop(%0) ( %0 = tickcount() - %0 )
#define debug_loop() for( new x; x < 1000000; x++ )
#define TimerSeconds(%0) ( %0 / 1000 % 60 )
#define TimerMilliseconds(%0) ( %0 % 1000 )
stock TimerConvert( timer, sztimer[], maxchars=0 )
{
formatex( sztimer, maxchars, "%02d seconds, %03d miliseconds.", TimerSeconds(timer) , TimerMilliseconds(timer) );
}
new gTest1, gTest2;
public plugin_init( )
{
register_clcmd( "say /test" , "test" );
register_clcmd( "say /test2", "test2" );
register_clcmd( "say /result", "res" );
}
public test( id )
{
new iTimer = debug_start();
debug_loop()
{
set_user_health( id, 250 );
}
debug_stop(iTimer );
gTest1 = iTimer;
return PLUGIN_HANDLED;
}
public test2( id )
{
new iTimer = debug_start();
debug_loop()
{
set_pev( id, pev_health, 250.0 );
}
debug_stop(iTimer );
gTest2 = iTimer;
return PLUGIN_HANDLED;
}
public res( id )
{
new szTimer1[40];
TimerConvert( gTest1, szTimer1, charsmax(szTimer1) );
new szTimer2[40];
TimerConvert( gTest2, szTimer2, charsmax(szTimer2) );
client_print( id, print_chat, "Fun set_user_health run in: %s", szTimer1 );
client_print( id, print_chat, "FakeMeta set_pev pev_heath run in: %s", szTimer2 );
client_print( id, print_chat, "%s is much faster!", gTest1 > gTest2 ? "Fakemeta" : "Fun" );
return PLUGIN_HANDLED;
}
Rezultat:
Code: Select all
Fun set_user_health run in: 00 seconds, 202 miliseconds.
FakeMeta set_pev pev_heath run in: 00 seconds, 390 miliseconds.
Fun is much faster!

what, format este mai rapid ca formatex

Nu conteaza functia care o folosesc ca sa formatez stockul avand in vedere ca oricum o sa scoti stock-ul pentru un plugin adevarat, folosesti stock-ul doar ca compari functii/metode intre ele.

nu ma refeream la stockul tau, am inlocuit set_user_health( id, 250 ); si set_pev( id, pev_health, 250.0 ); cu formatex si format si format este mai rapid decat formatex

1. Totul e facut de Black Rose de pe aliedmods nu de catre mine.
2. Ca sa popuplam mai bine topicul, ai putea sa arati cum ai facut asta si OutPut-ul ? Chiar daca pot sa fac si eu asta e pentru activiteate :P

cum nici functia random nu e un random ci un pseudo-random, asa si functia lui
in teorie pare totul ok, nu ?
ei bine uite ca ai uitat ce se intampla in spate : procesorul poate sa efectueze mai multe operatii deodata in timpul in care dai functia aia
tu ce zici ?

Lux0r, teoretic :P acele functii nu sunt chemate daca el nu foloseste copy-back-ul, nu ?
Oricum optez pentru formatex().

o alta metoda ar fi asta:
Code: Select all
#include <amxmodx>
#include <debug>
#include <fun>
#include <fakemeta>
new fun, fm, total, times;
const maxtimes = 5;
public plugin_init()
{
register_clcmd( "test", "ptest" );
}
public ptest(id)
{
new iStart1 = debug_cur_tick();
debug_loop_fortick()
{
set_user_health(id, 250 );
}
debug_stop_tick(iStart1);
new iStart2 = debug_cur_tick();
debug_loop_fortick()
{
set_pev( id, pev_health, 250.0 );
}
debug_stop_tick(iStart2);
if( debug_compare_ticks(iStart1, iStart2) == 1 )
{
fun++;
}
else
{
fm++;
}
if( total < 100 )
{
total++;
ptest(id);
}
else
{
debug_log( 5, "%s is faster(Fun: %i , Fm: %i, Total native calls: %i)!", fun > fm ? "set_user_health()" : "set_pev(id, pev_health, ... )", fun, fm, total );
fm = 0;
fun = 0;
total = 0;
times++;
if( times < maxtimes )
set_task( 3.0, "ptest", id );
}
return PLUGIN_HANDLED;
}
Output:
Code: Select all
[DEBUG, SysTime: 1498256736, Map: fy_snow, Players: 1] set_user_health() is faster(Fun: 58 , Fm: 43, Total native calls: 100)!
[DEBUG, SysTime: 1498256743, Map: fy_snow, Players: 1] set_user_health() is faster(Fun: 63 , Fm: 38, Total native calls: 100)!
[DEBUG, SysTime: 1498256751, Map: fy_snow, Players: 1] set_user_health() is faster(Fun: 65 , Fm: 36, Total native calls: 100)!
[DEBUG, SysTime: 1498256758, Map: fy_snow, Players: 1] set_user_health() is faster(Fun: 64 , Fm: 37, Total native calls: 100)!
[DEBUG, SysTime: 1498256766, Map: fy_snow, Players: 1] set_user_health() is faster(Fun: 55 , Fm: 46, Total native calls: 100)!
