So since enum structs are treated as an array, when using array fields they are treated as 2 dimensional arrays, and thus wouldn't correctly work with ArrayLists? The section outlining using them with ArrayLists could be updated, as this part makes it seem like my snippet should work.

The exception is when interacting with opaque data structures like ArrayList. For example, this is considered valid:

Re: Enum Structs Available This Holiday Season

You never gave blocksize to the ArrayList constructor.

While I can't say I know how Pawn internally treats 2-dimensional arrays, in this case you're storing an array reference nside another array.

It helps if you know arrays are a reference type. When I say that, I mean when you do this:

PHP Code:


		
			
int players[MAXPLAYERS+1];

you're actually creating an array with a length of MAXPLAYERS+1, then storing the memory address of the start of that array in players

Thank you, after setting the blocksize to sizeof(f), it worked perfectly.

Re: Enum Structs Available This Holiday Season

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

Re: Enum Structs Available This Holiday Season

methodmaps != classes

While 'enum structs' can hold multiple values because they are arrays, methodmaps can only hold one.

If you want to store something *in* methodmaps use StringMap's (or any other list). StringMap's are more readable. Example:

PHP Code:


		
			
methodmap Player < StringMap
{
    public Player(int id)
    {
        StringMap map = new StringMap();
        
        map.SetValue("id", id);
        map.SetValue("userid", GetClientUserId(id));
        map.SetValue("money", 100);
        
        return view_as<Player>(map);
    }
    
    property int Userid
    {
        public get() {
            int i;
            this.GetValue("userid", i);
            return i;
        }
    }
    
    property int Id
    {
        public get() {
            int i;
            this.GetValue("id", i);
            return i;
        }
    }
    
    property int Money
    {
        public get() {
            int i;
            this.GetValue("money", i);
            return i;
        }
        public set(int i) {
            this.SetValue("money", i);
        }
    }
    
    public bool IsValid()
    {
        return (GetClientOfUserId(this.Userid) > 0);
    }
    
    public bool InGame()
    {
        return (IsClientInGame(this.Id));
    }
}

public void OnClientPutInServer(int client)
{
    Player player = new Player(client);
    
    CreateTimer(30.0, SetPlayerMoneyTimer, player);
}

public Action SetPlayerMoneyTimer(Handle timer, Player player)
{
    if(!player.IsValid() || !player.InGame())
        return;
    
    player.Money = 2500;
    
    delete player;
}

if you remove the sugar it will look like this (decompiled):

PHP Code:


		
			
Player:Player.Player(id)
{
    new StringMap:map = StringMap.StringMap();
    StringMap.SetValue(map, "id", id, true);
    StringMap.SetValue(map, "userid", GetClientUserId(id), true);
    StringMap.SetValue(map, "money", any:100, true);
    return map;
}

Player.Userid.get(Player:this)
{
    new i;
    StringMap.GetValue(this, "userid", i);
    return i;
}

Player.Id.get(Player:this)
{
    new i;
    StringMap.GetValue(this, "id", i);
    return i;
}

void:Player.Money.set(Player:this, i)
{
    StringMap.SetValue(this, "money", i, true);
    return void:0;
}

bool:Player.IsValid(Player:this)
{
    return GetClientOfUserId(Player.Userid.get(this)) > 0;
}

bool:Player.InGame(Player:this)
{
    return IsClientInGame(Player.Id.get(this));
}

public void:OnClientPutInServer(client)
{
    new Player:player = Player.Player(client);
    CreateTimer(30.0, SetPlayerMoneyTimer, player, 0);
    return void:0;
}

public Action:SetPlayerMoneyTimer(Handle:timer, Player:player)
{
    new var1;
    if (!Player.IsValid(player) || !Player.InGame(player))
    {
        return Action:0;
    }
    Player.Money.set(player, 2500);
    CloseHandle(player);
    player = MissingTAG:0;
    return Action:0;
}

Re: Enum Structs Available This Holiday Season

New-style enum structs having a "methodmap" built-in is meant to solve the problem of methodmaps not having storage - what is lacking?

Hi Folks,

As of PR #934, SourceMod 1.10 has support for enum structs. This is some long-overdue syntactic sugar that makes SourcePawn feel more like a real language. Enum Structs are internally implemented as arrays, but the syntax is a lot nicer than before and we've fixed a lot of the corner cases and rough edges around using them. You can also have enum struct methods now.

You can read more about enum structs either in the Transitional Syntax Docs, or in the commit message.

If you're too impatient to read that, I'll just copy and paste the sample code from the doc:

PHP Code:


		
			
enum struct Rectangle {

  int x;

  int y;

  int width;

  int height;

 

  int Area() {

    return this.width * this.height;

  }

};

 

void DoStuff(const Rectangle r) {

  PrintToServer("%d, %d, %d, %d", r.x, r.y, r.width, r.height);

}

I love you man.. this is what we needed. Thanks bro!

Re: Enum Structs Available This Holiday Season

I can't help but notice when I try to include an enum struct in a native definition that the compiler tells me that I can't do this:

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.
