I have a method in my SM extension that I would like executed on the PlayerDeath event. I would like to return multiple values, a bool a string and an int, to my SM plugin from this call. Would this be a Forward or a Native?

I’m having a little difficulty with the structure for my extension. I’m using the example from the SDK. I seem to have some disconnect about whether the plugin calls the extension or the extension calls the plugin. Can someone give me an example of what should be in extension.h, extension.cpp, sample.inc, and sample.sp for the above to work?

Wrong section...

[Ajaxx]

My apologies, thanks for pointing this out. Which section do you suggest is the appropriate home for a post like this? SourceMod/General?

[WildCard65]

Scripting section under sourcemod possibly or some other one.

The MM:S C++ Coding forum is probably the best place for extension help. I'll move it there now.

Anyways, natives are functions that your extension can implement that can be called by plugins. Forwards are for calling plugin functions from the extension.

More info on these can be found at https://wiki.alliedmods.net/Writing_Extensions

I have a native that I'm trying to call from my plugin. The plugin is failing with

Load error: Native "OnPlayerDeath" was not found

I feel like I'm missing something simple. Can someone point me in the right direction please?


ultra.sp:

#include <sourcemod>
#include <ultra>
 
public Plugin:myinfo =
{
	name = "",
	author = "Ajaxx",
	description = "SourceMod Plugin",
	version = "1.0",
	url = ""
};
 
public OnPluginStart()
{
	HookEvent("player_death", Event_PlayerDeath)
}

public Event_PlayerDeath(Handle:event, const String:name[], bool:dontBroadcast)
{
	new String:weapon[64]
	GetEventString(event, "weapon", weapon, sizeof(weapon))

	new victim_id = GetEventInt(event, "userid")
	new attacker_id = GetEventInt(event, "attacker")
 
	new victim = GetClientOfUserId(victim_id)
	new attacker = GetClientOfUserId(attacker_id)

	new String:message[6];
	new result = OnPlayerDeath(message);
 
	if(result)
	{
		PrintToChat(attacker, message);
	}
}

ultra.inc:

native bool:OnPlayerDeath(String:text[]);

extension.cpp:

#include "extension.h"

Ultra g_Ultra;

SMEXT_LINK(&g_Ultra);

cell_t Native_OnPlayerDeath(IPluginContext *pContext, const cell_t *params)
{
	char* text;
	pContext->LocalToString(params[1], &text);

	text = "Stuff";

	return true;
}

const sp_nativeinfo_t ultra_natives[] =
{
	{ "OnPlayerDeath", Native_OnPlayerDeath },
	{ NULL, NULL },
};

void Ultra::SDK_OnAllLoaded()
{
	sharesys->AddNatives(myself, ultra_natives);
}

Have you verified with "sm exts list" that the extension is getting loaded?

For it to automatically get loaded when a plugin that uses it is loaded, you'll need to add the Extension struct to your inc file. Example from SDKTools:

public Extension:__ext_sdktools = 
{
    name = "SDKTools",
    file = "sdktools.ext",
#if defined AUTOLOAD_EXTENSIONS
    autoload = 1,
#else
    autoload = 0,
#endif
#if defined REQUIRE_EXTENSIONS
    required = 1,
#else
    required = 0,
#endif
};

That said, you can post-hook events directly in extensions pretty easily by adding an event listener with the IGameEventsManager2 interface in the sdk.

I added the struct, thanks for that. When I list the extensions “sm exts list” I get:

<FAILED > file “ultra.ext.dll”: Extension version is too new to load (7, max is 5)

It seems like a pretty straight forward message, but I can’t figure it out. In smsdk_config.h SMEXT_CONF_VERSION = "1.0.0.0". I’m using SourceMod version 1.5.3 and MetaMod version 1.10.1. Where is this version mismatch coming from?

You're getting that because you're compiling against sourcemod_central and then trying to run it on SourceMod 1.5.x. SourceMod uses a newer extension version in SourceMod 1.6 (which is what Central is).

The fix is to compile it against releases/sourcemod-1.5 instead.

That was exactly it, thank you.
