Passing a forward function 2 or more arguments!

Obbin · **Author**

Taken from Hawk552's Plugin API tutorial:

Code:

#include <amxmodx>

new Float:g_flDelay

public plugin_init()
{
    register_plugin("API Test - Core","1.0","Hawk552")
    
    g_flDelay = random_float(0.1,0.5)
    set_task(g_flDelay,"fnDoForward")
}

public fnDoForward()
{
    new iForward = CreateMultiForward("plugin_init_delay",ET_IGNORE,FP_FLOAT),iReturn
    if(iForward < 0)
        return log_amx("Forward could not be created.")
    
    if(!ExecuteForward(iForward,iReturn,g_flDelay))
        return log_amx("Could not execute forward.")
        
    return DestroyForward(iForward)
}

Code:

#include <amxmodx>

public plugin_init()
    register_plugin("API Test - Attachment","1.0","Hawk552")
    
public plugin_init_delay(Float:flDelay)
    log_amx("Forward executed %f seconds after plugin_init.",flDelay)

Now I want to pass plugin_init_delay another argument like this:
plugin_init_delay(Float:flDelay, iRand)

How do I do that?

Code:

You need to create the arguments in CreateMultiForward.
CreateMultiForward("plugin_init_delay",ET_IGNORE,FP_FLOAT, FP_CELL)

Then you need to add the extra arugument when executing. I'm not sure what you wanted  the extra argument for but that what you need to do ..
if(!ExecuteForward(iForward,iReturn,g_flDelay, iRand))

Thanks!
Now I have another problem:

Code:

//Natives added by Obbin
new iForward = CreateMultiForward("entity_touch",ET_STOP,FP_CELL), iReturn


/*
public pfn_touch( ptr, ptd )
{

    if( !ExecuteForward( iForward, iReturn, ptr, ptd ) )
    {
        log_amx( "Could not execute forward." )
    }

    if( !iReturn )
        return PLUGIN_CONTINUE

    return iReturn
}
*/

This dows just throw 2 "symbol is never used" warnings

Code:

//Natives added by Obbin
new iForward = CreateMultiForward("entity_touch",ET_STOP,FP_CELL), iReturn //ERROR IS HERE



public pfn_touch( ptr, ptd )
{

    if( !ExecuteForward( iForward, iReturn, ptr, ptd ) )
    {
        log_amx( "Could not execute forward." )
    }

    if( !iReturn )
        return PLUGIN_CONTINUE

    return iReturn
}

However this throws out "error 008: must be a constant expression; assumed zero" (on the line starting with "new iForward")

What is wrong?

If your going to execute a forward with two arguments. You need to make sure CreateMultiForward was setup for two arguments, etc

Code:

// One Argument
CreateMultiForward("entity_touch",ET_STOP,FP_CELL)

// Two Arguments
CreateMultiForward("entity_touch",ET_STOP,FP_CELL, FP_CELL)

// Three Arguments
CreateMultiForward("entity_touch",ET_STOP,FP_CELL, FP_CELL, FP_CELL)

Also where is new located? iForward = CreateMultiForward("entity_touch",ET_STOP,FP_ CELL), iReturn //ERROR IS HERE

Isn't it there?
I might have edited it but my short-time memory is like it is xP

EDIT: Hmm, i'm still getting it :S

Code:

new iForward = CreateMultiForward("entity_touch", ET_STOP, FP_CELL, FP_CELL)
new iReturn = 163 //Yes, I know this is just stupid, I'll deal with it later



public pfn_touch( ptr, ptd )
{

    if( !ExecuteForward( iForward, iReturn, ptr, ptd ) )
    {
        log_amx( "Could not execute forward." )
    }

    if( !iReturn )
        return PLUGIN_CONTINUE

    return iReturn
}

Code:

new iForward = CreateMultiForward("entity_touch",ET_STOP,FP_CELL), iReturn //ERROR IS HERE

^--- Did you put that into plugin_init() or as a global variable?

If you did that exactly in global then that why your getting that error..
You need to do new iForward as a global.

Global.

teame06 · 09-02-2006 , 16:38 Re: Passing a forward function 2 or more arguments!

Code:

new iForward

public plugin_init()
{
     iForward = CreateMultiForward("entity_touch",ET_STOP,FP_CELL)
}

That what your suppose to do .. You can't use a native in a global like that.

Hmm, but it needs to be called on startup, can I use plugin_init in an include file AND in the sma?
It needs to be called at startup and it needs to be in a inc.

Ok, Now i'm really confused on what you are trying to do with Dynamic Forwards. I would attach your source cause you just confused the hell out of me trying to put this into include.
