Code:

error 135: cannot use enum struct type "MapChoices_GetMapData" in natives

Won't this limit their usefulness?

Also, the error is reporting the native name rather than the enum struct name.

Re: Enum Structs Available This Holiday Season

PHP Code:


		
			


#pragma semicolon 1

#pragma newdecls required



#include <sourcemod>



enum struct PlayerInfo

{

    char steam[65];

    char name[65];

    int time;

};



ArrayList g_Players;



public void OnPluginStart()

{

    g_Players = new ArrayList(sizeof(PlayerInfo));

    HookEvent("player_disconnect", Event_PlayerDisconnect);

    

    RegConsoleCmd("sm_lastpl", Command_Last);

}



public void Event_PlayerDisconnect(Event event, const char[] name, bool dontBroadcast) 

{

    PlayerInfo info;

    event.GetString("networkid", info.steam, sizeof(PlayerInfo::steam));

    

    if (StrEqual(info.steam, "BOT"))

    {

        return;

    }

    

    event.GetString("name", info.name, sizeof(PlayerInfo::name));

    info.time = GetTime();

    

    g_Players.PushArray(info);

    if (g_Players.Length > 10)

    {

        g_Players.Erase(0);

    }

}



public Action Command_Last(int client, int args)

{    

    for (int i = 0; i < g_Players.Length; i++)

    {

        PlayerInfo info;

        g_Players.GetArray(i, info);



        char time[65];

        FormatTimeDuration(time, sizeof(time), GetTime() - info.time);

        PrintToConsole(client, "[%02d] %s : %s : %s ago", i + 1, info.steam, info.name, time);

    }

    

    return Plugin_Handled;

}





int FormatTimeDuration(char[] buffer, int maxlen, int time)

{

    int hours = time / 3600;

    int minutes = (time / 60) % 60;



    if (hours > 0)

    {

        return Format(buffer, maxlen, "%dh %dm", hours, minutes);        

    }

    

    if (minutes > 0)

    {

        return Format(buffer, maxlen, "%dm", minutes);        

    }

    

    return Format(buffer, maxlen, "%ds", time % 60);        

}

Here's an example with structs and arraylists.
I don't know how sizeof of structs works, but if i have 3 members, calling g_Players = new ArrayList(3) it's wrong (only the first paramater - "steam" works fine), so g_Players = new ArrayList(sizeof(PlayerInfo)) it's the correct one.

BAILOPAN, great update, so handy, btw can we wait some update in methodmaps part ? We need some improvements there, something look like a clases with proper constructor and destructor or may be a posibility to create values inside a methodmap class, like in a new struct and use them only there

Enum structs are the near-term workaround for lack of instance-variables in methodmaps.

Re: Enum Structs Available This Holiday Season

I've made a very slight change to the enum struct syntax. The final closing brace (}) must now be followed by a newline. Semicolons are not allowed even with #pragma semicolon, to be consistent with most other close-brace scenarios.

That explains the error I just encountered with the latest build. The snippet in the original post should be updated to reflect the change.

Re: Enum Structs Available This Holiday Season

Hello,

Why this one is invalid ?
error 008: must be a constant expression; assumed zero

PHP Code:


		
			
enum struct Foo {
    int a;
    int b;
}

Foo bar[65];

public void OnPluginStart() {    
    Foo i = bar[0];
    i.a = 1;
    i.b = 2;
}

this is valid though: bar[0].a

used version 6421

For now, I think you can do Foo i; i = bar[0];. I checked that it compiled, but not that it worked as expected. Assignment here is handled differently than initialization and initialization only works with constants. We'll look into it further.

As the very first post says, this feature is merely syntactic sugar.
