Stop assuming that entities have a predefined index. Index will vary.

Please explain properly what are you trying to do. Giving a weapon like give_item or give a weapon from the ground?

It doesn't realy matter, i'm trying to make an example using okapi_call() by calling a function to learn, that's all. Can you provide any example ?

Example with TouchItem, as i say in function reference when id touch the entity then the function Respawn() will be called, i want to use okapi_call() to Call ItemTouch for Id, like that Id is realy touching the an item and happen what is suppose to happen when is touching that item.

Now should i press View deleted comment¤ so i can fully take revenge

I don't have time to explain why it does not work, maybe later. Items are contained in an armoury_entity, so the proper function to call is CArmoury::Touch. Find and play with that function.
ItemTouch does not work as you think.

Ok, so here we go.

In order to understand why it's crashing you need to understand what the game does and what happens.
As you have already discovered, ItemTouch is not called for weapons, only for items(such as item_assaultsuit).

Items are contained in an armoury_entity, they are not a stand alone entity(what you see on the ground is an armoury_entity, not an item_assaultsuit). When you touch an armoury_entity CArmoury::Touch is called and based on m_iType offset the proper weapon/item is given to player by calling GiveNamedItem. GiveNamedItem creates the item and force touch with the player. That's the moment when ItemTouch is called.

The flow is like that:
CArmoury::Touch -> GiveNamedItem -> DispatchTouch -> ItemTouch.

So 2 touch events happen:
Firstly, a player touch an armoury_entity, then the new item that was created touch the player. ItemTouch handles the second touch and you tried to use it to handle the first touch.

It crashes because you were providing an invalid entity index, because the item was not yet created and you were passing it's index to ItemTouch.

Now, about what you tried to do:
CArmoury::Touch is basically Ham_Touch with an armoury_entity index, so okapi is not really needed for that. If you still want to use okapi(and you should only for learning, not for using in a plugin that you plan to release, always go with ham if you can) then find CArmoury::Touch.

Edit:Works!!! (map: fy_snow)

PHP Code:

#include <amxmodx> 
#include <okapi> 

new const Symb[] = "?ArmouryTouch@CArmoury@@QAEXPAVCBaseEntity@@@Z" 
new okapi_func:test; 

public plugin_init() 
{ 
    new Handle = okapi_mod_get_symbol_ptr( Symb ); 
    test = okapi_build_method( Handle, arg_void, arg_cbase, arg_cbase ); 

    register_clcmd( "say /test", "testp" ); 
} 

public testp(id) 
{ 
    okapi_call( test, 100, id ); 
}
