Ah, oops. I probably confused with something else.

The posted code doesn't work?

EDIT: Ah SetAnimation. The thing with this function is that because of optimization at compilation, function is split in two, and it's not really possible to hook that with Okapi. You can hook the original function, but this won't be called for all. Well, for this specific function you can probably use this module: https://forums.alliedmods.net/showpo...51&postcount=7

Posted code works like a charm seems like just for func call does not matter if it is split or not. I need it for SetAnimation for player. I have not seen any problems with that yet. Animations are send to player properly. Just one more question. Is it possible to get the ID of weaponmodel(p_model) of the weapon?

[Arkshine]

Yes, the posted code will work, but you won't get the all the original calls. I've explained more here https://forums.alliedmods.net/showpo...72&postcount=2.

About calling the function, yes, doesn't matter, if you use the original function address.

Search, it's done by the client. You can't change client's p_ model entvars, you'll need to create another one separately.

Do you have any piece of code for that please? I would like to get the muzzleflash origin using GetBonePosition or GetAttachment.

What do you want to do?

***waiting for Okapi update***

[HamletEagle]

I'm trying to hook CHostage::RePosition, this function reset the hostage to their previous position, no matter if they are killed/rescued/somewhere in the map. In the plugin I need to use okapi to hook a function that has vector as param, so I can't use orpheu, because using both okapi and orpheu doesn't seem resonable to me.

You can hook any function that uses a combination of these types:

We can't hook functions that have as arguments: CHostage *const this ? With orpheu it's easy, just need to pass a valid hostage index when calling the function.

Orpheu code which works:

{
	"name"    : "RePosition",
	"class"   : "CHostage",
	"library" : "mod",
	"identifiers" : 
	[
		{
			"os"    : "windows",
			"mod"   : "cstrike",
			"value" : [0x83,"*","*",0x56,0x8B,"*",0x57,0x33,"*",0x8B,"*","*",0x57,0x89,"*","*","*" ,0x89,"*","*","*",0x8B]
		},
		{
			"os"    : "linux",
			"mod"   : "cstrike",
			"value" : "_ZN8CHostage10RePositionEv"
		}
	]
}

PHP Code:

#include <amxmodx>
#include <orpheu>
#include <engine>
#include <fakemeta>

public OrpheuFunction:CHostage_RePosition

public plugin_init()
{
    CHostage_RePosition = OrpheuGetFunction("RePosition", "CHostage")
    register_clcmd("test", "test")
}

public test(id)
{
    new HostageEnt = -1
    while((HostageEnt = find_ent_by_class(HostageEnt, "hostage_entity")))
    {
        if(pev_valid(HostageEnt))
        {
            OrpheuCall(CHostage_RePosition, HostageEnt)
        }
    }
} 


Then, when trying to convert it to okapi I fail:

PHP Code:

#include <amxmodx>
#include <engine>
#include <fakemeta>
#include <okapi>

new okapi_func:CHostage_RePosition

public plugin_precache()
{
    register_clcmd("test", "test")
    
    new const CHostageRePositionSignature[] = {0x83,0xDEF,0xDEF,0x56,0x8B,0xDEF,0x57,0x33,0xDEF,0x8B,0xDEF,0xDEF,0x57,0x89,0xDEF,0xDEF,0xDEF ,0x89,0xDEF,0xDEF,0xDEF,0x8B}
    new const CHostageRePositionSymbol   [] = "_ZN8CHostage10RePositionEv"

    new OkapiHandle
    if
    (
        (OkapiHandle = okapi_mod_get_symbol_ptr(CHostageRePositionSymbol)) || 
        (OkapiHandle = okapi_mod_find_sig(CHostageRePositionSignature, sizeof CHostageRePositionSignature))
    )
    {
        CHostage_RePosition = okapi_build_function(OkapiHandle, arg_void)
    }
} 

public test(id)
{
    new HostageEnt = -1
    while((HostageEnt = find_ent_by_class(HostageEnt, "hostage_entity")))
    {
        if(pev_valid(HostageEnt))
        {
            okapi_call(CHostage_RePosition, HostageEnt)
        }
    }
} 


When using it like this it throw an error like: "expected 1 arg", which seems logical because on okapi_build_function I don't pass any args, but this is fine in orpheu, so I'm confused. The object from function header is refered in pawn as an entity index, right ?

I've also tried to add arg_int after arg_void(the function does not return anything) but this results in a crash. Sorry if I didn't explain well, but I'm pretty nervous right now.

[Arkshine]

RePosition is a member of CHostage class, so, you need to build the okapi function using okapi_build_method.
okapi_build_function is essentially for functions without class or static.
