[SAMURAI16]

Today we will discuss about touch stuff.
We will talk about:
1. Touch with natives
2. Forwards touch
3. Block touch operation
4. Fake touch

So, let's start


1. Touch with natives
Engine way:

PHP Code:

#include <amxmodx>
#include <amxmisc>
#include <engine>


public plugin_init() {
    register_plugin("Touch Test","0.1","SAMURAI");
    
    // now registers a touch action to a function. 
    register_touch("touched","toucher","hook_touch"); 
}


public hook_touch(touched,toucher)
{
    if(is_user_admin(toucher) && is_user_bot(touched))    
    {
        client_print(0,print_chat,"kbooom")
    }
    
} 


touched = Who are touched by Toucher
toucher = Who touch

If you want to filter touched / toucher
An example :
Only running hook_touch if a player touch something..

PHP Code:

register_touch("player","*","hook_touch"); 


2. Forwards touch:
Engine way:

PHP Code:

#include <amxmodx>
#include <amxmisc>
#include <engine>


public plugin_init() {
    register_plugin("Touch test","0.1","SAMURAI");
    
    
}

// Called when two entities touch/collide. 
public pfn_touch(ptr,ptd)
{
    new classname[32]
    entity_get_string(ptr,EV_SZ_classname,classname,31) 

    
    if ( equal(classname, "hostage_entity") ) 
    {
        client_print(0,print_chat,"damn touched");
        // and other stuff
    }
} 


Fakemeta way:

PHP Code:

#include <amxmodx>
#include <fakemeta>

public plugin_init() {
    register_plugin("Touch Test","0.1","SAMURAI");
    
    register_forward(FM_Touch,"hook_touch");
}

public hook_touch(ptr,ptd)
{
    new classname[32]
    pev(ptr,pev_classname,classname,31)
    
    
    if ( equal(classname, "hostage_entity") ) 
    {
        client_print(0,print_chat,"damn touched");
        // and other stuff
    }
    
} 


3. Block touch operation:
On Engine:
To block touch use return PLUGIN_HANDLED;

On Fakemeta:
use return FMRES_SUPERCEDE;

4. Fake Touch:
This will simulates two entities colliding/touching.
Engine:

PHP Code:

fake_touch(Touched,Toucher) 


Fakemeta:

PHP Code:

dllfunc(DLLFunc_Touch, touched, toucher)

I don't think I've ever seen anything as general as this, but for a list, it's nice.

[flyeni6]

so this is basically if 2 players touch?

[SAMURAI16]

2 players touch, one player and one entity or 2 entityes

[flyeni6]

oohhh lol im such a newb.

good tutorial

[VEN]

register_touch("touched","toucher","hook_touch");

You should mention that for 1st and 2nd parameter an actual classname should be specified.

this is for entity's touching . which players are a class of entitys .

A little thing to add to the tutorial,that you can filter toucher/touched in register_touch.

Example:Only running hook_touch if a player touch something

register_touch("player","*","hook_touch");

One question,
why doesn't this work?

#include <amxmodx>
#include <fun>
#include <engine>

public plugin_init() {
    register_plugin("Nadepassing", "1.00", "MaTTe");
    register_touch("player", "hegrenade", "hegrenade_touch");
}

public hegrenade_touch(touched, toucher) {
    new model[99]
    entity_get_string(toucher, EV_SZ_model, model, 99);
    new owner = entity_get_edict(toucher, EV_ENT_owner);
    
    new touchedname[32], ownername[32];
    get_user_name(touched, touchedname, 31);
    get_user_name(owner, ownername, 31);
    
    if(equal(model, "w_hegrenade.mdl")) {
        client_print(0, print_chat, "%s passed the grenade to %s", ownername, touchedname);
        remove_entity(toucher);
        give_item(touched, "weapon_hegrenade");
    }   
}
