This is a compilation of examples, explanations, and answers for commonly asked questions / issues.
The Countdown
Code:
#include <amxmodx>
#define TASKID 1996
#define SECONDS 10
new iSeconds
public plugin_init()
{
register_plugin( "Countdown Example", "1.0", "Wrecked" )
register_logevent( "LogEventRoundStart", 2, "1=Round_Start" )
}
public LogEventRoundStart()
{
if( task_exists( TASKID ) )
remove_task( TASKID )
iSeconds = SECONDS
set_task( 1.0, "TaskShowCountdown", TASKID, _, _, "a", SECONDS )
}
public TaskShowCountdown()
{
set_hudmessage( 120, 120, 120, 0.50, 0.50, 0, 0.1, 0.8, 0.1, 0.1, -1 )
show_hudmessage( 0, "Seconds Remaining: %i", iSeconds-- )
}
Detecting Kill/Headshot Streaks
Code:
#include <amxmodx>
new Headshots[33]
new Kills[33]
public plugin_init()
{
register_plugin( "How To Keep Kill Counts", "1.0", "Wrecked" )
register_event( "DeathMsg", "EventDeathMsg", "a" )
register_logevent( "LogEventRoundStart", 2, "1=Round_Start" )
}
public EventDeathMsg()
{
new killer = read_data( 1 )
new victim = read_data( 2 )
Headshots[victim] = 0
Kills[victim] = 0
Kills[killer]++
if( read_data( 3 ) ) // headshot
Headshots[killer]++
// Kills holds kills of each player
// Headshots holds headshots
}
public LogEventRoundStart()
{
arrayset( Headshots, 0, 33 )
arrayset( Kills, 0, 33 )
}
Once Every x Rounds
Code:
#include <amxmodx>
#define ROUND_INTERVAL 4
new iRound
public plugin_init()
{
register_plugin( "Do Something Every X Rounds", "1.0", "Wrecked" )
register_logevent( "LogEventRoundStart", 2, "1=Round_Start" )
}
public LogEventRoundStart()
{
if( ( ++iRound % ROUND_INTERVAL ) == 1 )
// do whatever you need to do here
}
Blocking Weapon Pickup
Code:
#include <amxmodx>
#include <hamsandwich>
public plugin_init()
{
register_plugin( "Block Weapon Pickup", "1.0", "Wrecked" )
RegisterHam( Ham_Touch, "weaponbox", "HamTouchPre", 0 )
RegisterHam( Ham_Touch, "armoury_entity", "HamTouchPre", 0 )
}
public HamTouchPre( weapon )
return HAM_SUPERCEDE; // blocks function call
Properly Removing Buyzones (by Exolent[jNr])
Code:
#include < amxmodx >
#include < engine >
#include < fakemeta >
new const info_map_parameters[ ] = "info_map_parameters";
new g_hSpawn;
public plugin_precache( ) {
new iEntity = create_entity( info_map_parameters );
DispatchKeyValue( iEntity, "buying", "3" );
DispatchSpawn( iEntity );
g_hSpawn = register_forward( FM_Spawn, "FwdSpawn" );
}
public FwdSpawn( iEntity ) {
static szClassname[ 32 ];
entity_get_string( iEntity, EV_SZ_classname, szClassname, 31 );
if( equal( szClassname, info_map_parameters ) ) {
remove_entity( iEntity );
return FMRES_SUPERCEDE;
}
return FMRES_IGNORED;
}
public plugin_init( ) {
if( g_hSpawn > 0 ) {
unregister_forward( FM_Spawn, g_hSpawn );
}
}
Properly Removing an Entity at Plugin Start (by Alucard^)
Code:
#include <amxmodx>
#include <fakemeta>
new const g_RemoveEntity[] = "classname_here";
public plugin_precache()
{
register_plugin("Fine", "and", "you?");
// Remember to do this in plugin_precache, if you
// do this in plugin_init( ) this will not work!
register_forward(FM_Spawn, "HookFmSpawn");
}
public HookFmSpawn(iEntity)
{
if(!pev_valid(iEntity) )
return FMRES_IGNORED;
static szClassName[32];
pev(iEntity, pev_classname, szClassName, 31);
if(equali(szClassName, g_RemoveEntity) )
{
engfunc(EngFunc_RemoveEntity, iEntity);
return FMRES_SUPERCEDE;
}
return FMRES_IGNORED;
}
What is the proper way to respawn someone?
Well, there are two methods that are correct and efficient.
Code:
// GOOD, hamsandwich
ExecuteHamB( Ham_CS_RoundRespawn, playerindex )
// GOOD, fakemeta
set_pev( playerindex, pev_deadflag, DEAD_RESPAWNABLE )
// BAD, fun
// This is usable, but requires a fix that really isn't worth it.
spawn( playerindex )
// BAD, cstrike
cs_user_spawn( playerindex )
What module should I use for my large plugin? Fakemeta or engine?
You should use whatever module gets the job done. The actual efficiency impact between including either is very trivial. Don't be hesitant to include both if you need both to get what you need done properly.
I've compiled my plugin and the loose indentation warning has come up. What is this and how can I fix it?
This warning shows up whenever you indent your lines with spaces AND tabs. Conform to using one style; I personally use tabs because they're much easier.
How do I dynamically add values into my menu title / items?
Code:
menufunc()
{
new info[128]
formatex( info, 127, "Welcome to the Point Shop^nYour Points: %i", iVariableForPoints[id] )
new menu = menu_create( info, "HandlerFunction" )
// rest of menu code
}
If you have any issues that you feel people too commonly ask, please post the issue/question in a post or PM and I'll consider adding it to the list. This is the list that I thought up that people commonly ask.
