Callback problems - joco96 - 28.08.2009

Hi!
I know there is another callback topic, but I have another problem. :/
I'm using this kind of callback:

Код:

cell
	amx_addr,
	amx_ret,
	* amx_physAddr;
int
	amx_idx;
if (!amx_FindPublic(pAMX, "SomeFunction", &amx_idx))
{
	amx_PushString(pAMX, &amx_addr, &amx_physAddr, SomeString, 0, 0);
	amx_Push(pAMX, SomeInt);
	amx_Exec(pAMX, &amx_ret, amx_idx);
	amx_Release(pAMX, amx_addr);
}

I call a function from Pawno like StartListening.
and then the function in the plugin saves the amx variable (pAMX = amx).
and then later if there is an incoming data it calls the callback with the same amx.
but I'm using this amx 2 times like 2 callbacks, can it be a problem?
And the callback doesn't works. I put a printf in the callback and it doesn't appears :/.

Please answer my questions, and give me a good callback example

.

Thanks!

1) No.
2) Your executing the callback if it cannot find the callback. Remove the !.

1) Ok
2) I know it calls it, but there is another problem...
When it calls the function the printf doesn't appear.
Like:
Plugin callback:

Код:

char 
	SomeString[256];
cell
	amx_addr,
	amx_ret,
	* amx_physAddr;
int
	amx_idx,
	SomeInt;
if (!amx_FindPublic(pAMX, "OnSomethingHappens", &amx_idx))
{
	amx_PushString(pAMX, &amx_addr, &amx_physAddr, SomeString, 0, 0);
	amx_Push(pAMX, SomeInt);

	amx_Exec(pAMX, &amx_ret, amx_idx);
	amx_Release(pAMX, amx_addr);
}

Pawno callback:

pawn Код:

public OnSomethingHappens(someint, somestring[]) {
    printf(somestring);
}

And then there are empty spaces in the server window.
Like:
"
Somebody joined the server.
<== Here is the printf. Nothing here
Somebody left the server.
"
And sometimes it getting crazy... It gets the last string, not the new :/.

So I don't know what's the problem...

You are not initializing the character array you are passing to amx_PushString or the integer you are passing to amx_Push:

Код:

char
	SomeString[256] = "string";
int
	SomeInt = 0;

Also, amx_FindPublic does return 0 on success, so that part of your code is correct.

Hi, again!
Now I can printf the variable(SomeString). But if I want to print it like this: printf("SomeString: %s", somestring);
I get this:
SomeString:
But If I print just the somestring var like this: printf(somestring);
I get the var's value :/.
So I don't know what's the problem...
Please help me

Usually if I use printf("Thestring: %s", var); and get "Thestring: " as output, it's because the "var" variable is empty.
Try using something like printf("TestString: %s", "Here it is!"); If that works, then your variable being passed is empty.

format(string, sizeof(string), "%s", somestring);
printf("SomeString: %s", string); // It works =)

Re: Callback problems - Tony_Montana - 10.11.2009

me too
i got a little probleme
i tried this in my plugin

Код:

	int clients = 2;
	if(amx_FindPublic(amx, "OnClientConnect", &clients) == AMX_ERR_NONE)
	{
		amx_Push(amx, clients);
		amx_Exec(amx, &amx_ret, clients);
		amx_Release(amx, amx_addr);
		
	}
	else
	{
		logprintf("there is a probleme");
	}
	return 1;

my function looks good
now this is my pawn code

pawn Код:

}

public OnRconCommand(cmd[])
{

    if(strcmp(cmd, "test", true) == 0)
    {
      Test();
        
      return 1;
    }
    return 1;
}

public OnClientConnect(clients)
{
    printf("%d clients", clients);
    if(clients == 1)
    {
      printf("the first client");
    }
    else if(clients == 2)
    {
      print("the second one");
    }
    
}

ok my function is Test()
and it calls the callback "OnClientConnect(clients)"
so clients must be 2 as you see here "int clients = 2;"
but it always print "22 clients" for me even if i change "int clients = 3;"
what is the probleme here ?
thx

Hi, I am trying to accomplish the same task. (push my data to a callback) the only examples I have found use "amx_FindPublic", would you kindly point to an alternative ?
