I'm realy confusing at using celltravtrie library, i have some questions:

- In my code i use TrieKeyExists native to check if exist an Key exist on the g_tBlock var, but i create g_tBlock using TravTrie, is giving me an warning with Tag Mismach, but working compile and working scan if key exist. I should let how is it or exist anoter native who replace that for TravTrie library?

- How to use Iterator to save key in trie when map changed? That's realy confuse for me.

* I realy wanna learn how to use TravTrie, seems realy useful and i wanna use on future, thanks

Here's the code:

#include <amxmodx>
#include <amxmisc>
#include <fakemeta>
#include <celltravtrie>

new const PLUGIN[]	= "Pick Up Manager",
	 VERSION[]	= "0.2",
	  AUTHOR[]	= "Craxor";

new TravTrie:g_tBlock;
new giTypeCvar;

public plugin_init( )
{
	register_plugin
	(
		.plugin_name = PLUGIN, 
		.version     = VERSION, 
		.author      = AUTHOR
	)

	g_tBlock = TravTrieCreate( );

	register_forward( FM_Touch, "WeaponTouchFwd" );

	register_concmd( "amx_pum_addkey" ,"addkey", ADMIN_BAN, " < Weapon key-name to block > ");
	register_concmd( "amx_pum_remkey" ,"remkey", ADMIN_BAN, " < Weapon key-name to block > ");

	giTypeCvar = register_cvar("pum_type", "1" );
}

public addkey( id, level, cid )
{
	if( !cmd_access( id, level, cid, 2 ) )
		return PLUGIN_HANDLED;

	new Arg1[16];
	read_argv( 1, Arg1, charsmax( Arg1 ) );

	new adder[64];
	formatex( adder, charsmax( adder ), "models/w_%s.mdl", Arg1 );

	TravTrieSetCell( g_tBlock, adder, 1 );
	return PLUGIN_HANDLED;
}

public remkey( id, level, cid )
{
	if( !cmd_access( id, level, cid, 2 ) )
		return PLUGIN_HANDLED;

	new Arg1[16];
	read_argv( 1, Arg1, charsmax( Arg1 ) );

	new adder[64];
	formatex( adder, charsmax( adder ), "models/w_%s.mdl", Arg1 );

	TravTrieDeleteKey( g_tBlock, adder );
	return PLUGIN_HANDLED;
}
 
public WeaponTouchFwd( Entity, Id )
{
	if ( !pev_valid( Entity ) || !pev_valid( Id ) || !is_user_alive( Id ) )
		return FMRES_IGNORED;

        new Model[32];
        pev(Entity, pev_model, Model, charsmax( Model ) );

	new iCvarValue = get_pcvar_num( giTypeCvar );

	if( TrieKeyExists( g_tBlock, Model ) )
	{
		switch( iCvarValue )
		{
			case 1: engfunc( EngFunc_RemoveEntity, Entity );
			case 2: return FMRES_SUPERCEDE;
			default: return FMRES_IGNORED;
		}
	}
	return FMRES_IGNORED;
}

You should just tag it:

PHP Code:

TrieKeyExists( Trie:g_tBlock, Model ) 


Or if you want it like a stock:

PHP Code:

stock bool:TravTrieKeyExists(TravTrie:HandleTravTrie, const Key[])
{
    return TrieKeyExists(Trie:HandleTravTrie,key)
} 


Also, given your code, you don't need TravTries, just use normal tries. You would use TravTrie when you want to iterate over all keys(see an example in Entities Resources Replacement). Also consider to replace FM_Touch with Ham_Touch/register_touch, depending on your needs. FM_Touch is bad because you get all kind of touch between entities, while with ham/engine you can filter by classname inside module and it's better.
Also, doing pev_valid(id) is dumb.

- How to use Iterator to save key in trie when map changed? That's realy confuse for me.

What? Trie is deleted on map change, if you want to save stuffs between maps you need files/vault/sql.

About tries ... Maybe i'm wrong but only TRIES are deleted on map change, that's why i'm using TravTrie for saving tries on map change( i know how to work with normal tries, i've problems only with TravTries ).


But i don't test yet your code ... after test i come back with an answer, anyway, thanks for making time to answer

You are indeed, wrong.

[klippy]

TravTries get released at mapchange too. TravTries are just a hack, they are just a data structure having both CellArrays and CellTries under the hood.

ok, thanks guys, i will use vaults for saving data on map change as hamlet(and addonzz) said.
