[C#] Enigma.D3

I'm afraid it won't work as I will get all items from

engine.SnoGroupsByCode[(int)groupId].x10_Container

which in case of SnoGroupId.Scene contains also other types of SNO definitions like animations and conditions. So casting will misinterpret data (i mean i.e. animation SNO will be "reinterpret_casted" to scene SNO).

Seems I was wrong, they didn't remove group ID, they just joined 2 fields so it's now a byte on offset 7. SnoHelper is updated. I've also added the SnoHeader to all SNO types.

I just updated BuffManager so you can use that to tell if you have a certain buff or not, but it must be visible in the UI to work. Keep in mind some buffs might not be the same power SNO ID as the actual skill. I also updated UXIcon so that can be used to tell if a skill is disabled (not having enough resources, warping, cinematic, CCed etc.). Regarding skill casts there might be something in PlayerInput, but you will have to try to figure that one out yourself.

Thanks again. Everything I wanted is working now except one thing. I'm still clueless on how to detect if a spell is being cast, so after looking at other stuff in this thread I figured the best alternative I can accomplish is to check if I'm in melee range of an enemy. Because then I'm most likely spamming spells anyway. The problem is that the method only works about 95% of the time. A few random mobs aren't detected. Doesn't seem to be any clear pattern. I've had the method return true only to return false on the same kind of mob later on. Even when I remove checks for ActorType and TeamId I can't find the missing acds. Any ideas?

private static bool EnemyClose(ActorCommonData Player)
{
    float Dist;
    float ClosestDist = -1;
    float DeltaX;
    float DeltaY;
    float DeltaZ;
    ExpandableContainer<Actor> actors = Engine.Current.ObjectManager.x928_RActors;

    for (short i = 0; i < actors.x10C_Count; i++)
    {
        Actor currentActor = actors[i];
        ActorCommonData acd = ActorCommonDataHelper.GetAcd(currentActor.x088_AcdId);

        //if (acd != null)
            //Console.WriteLine(acd.x190_TeamId + "\t" + acd.x184_ActorType + "\t" + acd.x004_Name);

        if (acd != null && acd.x184_ActorType == ActorType.Monster && acd.x190_TeamId == 10)
        {
            DeltaX = acd.x0D0_WorldPosX - Player.x0D0_WorldPosX;
            DeltaY = acd.x0D4_WorldPosY - Player.x0D4_WorldPosY;
            DeltaZ = acd.x0D8_WorldPosZ - Player.x0D8_WorldPosZ;
            Dist = (float)Math.Sqrt(DeltaX * DeltaX + DeltaY * DeltaY + DeltaZ * DeltaZ);
    
            if (Dist < ClosestDist || ClosestDist == -1)
            {
                ClosestDist = Dist;
     
                if (ClosestDist <= 15)
                {
                    return true;
                }
            }
        }
    }

    //Console.WriteLine(ClosestDist);
    return false;
}

Great job, now as I can obtain Sno.Scene data, I noticed some bug. I extract NavCells using following code:

            Enigma.D3.Sno.Scene.NavCell[] nav_cells = sno_scene.x180_NavZoneDefinition.x08_NavCells;

            if (nav_cells == null)
                return;

            foreach (Enigma.D3.Sno.Scene.NavCell nav_cell in nav_cells)
            {
                // skip not walkable
                if ((nav_cell.x18 & 1) == 0)
                    continue;

                float min_x = nav_cell.x00_Vector3D.x00_X;
                float min_y = nav_cell.x00_Vector3D.x04_Y;
                float min_z = nav_cell.x00_Vector3D.x08_Z;

                float max_x = nav_cell.x0C_Vector3D.x00_X;
                float max_y = nav_cell.x0C_Vector3D.x04_Y;
                float max_z = nav_cell.x0C_Vector3D.x08_Z;

                cells.Add(new Nav.Cell(min_x, min_y, min_z, max_x, max_y, max_z));
            }

After transition to 2.1 I have missing cells. It looks like NavCells from end of the array (cells are defined in NavCells array "row by row") have invalid AABB coordinates (almost zero) thus are invisible. For example in 166 element array cells from 154 up are invalid. There is some pattern here as you can clearly see on attached screenshot, any ideas? Maybe those 166 are not all cells, maybe array has more elements actually?

You should use the EnumerateX methods on the helpers instead, they're better at handling collection changes (also better performance), and you could try calling TakeSnapshot() on each item to read all at once, so you don't have D3 modify stuff between reading the various properties. Also a good idea to check ID for non -1 after snapshot, -1 meaning a "disposed" item.

Should be fixed now, my bad.

[CrEEzz]

Just to let you know. Everything works like a charm now. Thanks a lot for support. Meanwhile how can I get item attributes. Suppose those are somewhere in game balance but I can't figure it out.

Edit: Intelligence/Strength/Dexterity/Vitality can be read from attributes IntelligenceItem/StrengthItem/... but critical chance and other are not there

[bastiflew]

just a small piece of code for checking if a power is ready or is active :

        public static bool IsPowerReady(this ActorCommonData acd, SnoPower power)
        {
            return acd.GetAttributeValue(AttributeId.PowerCooldown, (int) power) <= 0;
        }

        public static bool IsPowerActive(this ActorCommonData acd, SnoPower power)
        {
            for (var i = (int) AttributeId.BuffIconCount0; i <= (int) AttributeId.BuffIconCount31; i++)
            {
                var active = acd.GetAttributeValue((AttributeId) i, (int) power);
                if (active > 0)
                    return true;
            }
            return false;
        }

Usage :

var akaratActive = ActorCommonDataHelper.GetLocalAcd().IsPowerActive(SnoPower.X1_Crusader_AkaratsChampion);

So anyone can help me with getting item attributes?

So anyone can help me with getting item attributes?

Crit C is Attrib.CritPercentBonusCapped (read it as float). Dunno what else you need

[bastiflew]

Every infos you need are in attributes, except the item level, or item type.

[CrEEzz]

I feel really lame now xD and what about displayed item info so I can check if its mystical Wand of Woh ?

@Dolphe: I need CHD, sockets num, elemental damage, resource reduction, cooldown reduction, attack speed.

[enigma32]

Maybe you can play with EnumerateAttributes in https://subversion.assembla.com/svn/...ibuteHelper.cs to figure out what attributes are interesting based on items you already have with those properties. Here is part of an attribute dump method I have:

Func<string> debugAttribDumpTest = () =>{
    var acd = ActorCommonData.Local;
    var attribDescriptors = Engine.Current.AttributeDescriptors;
    var q = acd.EnumerateAttributes().Select(a => new { Id = a.x04_Key & 0xFFF, Mod = a.x04_Key >> 24, Value = a.x08_Value, Descriptor = attribDescriptors.Single(d => d.x00_Id == (a.x04_Key & 0xFFF)) });
    return string.Join(Environment.NewLine, q.Select(a => string.Join("\t",
        a.Id,
        a.Mod == 0xFFFFF ? "-1" : a.Mod.ToString(),
        "0x" + a.Mod.ToString("X8").Substring(3),
        a.Descriptor.x1C_Name,
        a.Descriptor.x10_DataType == 1 ? a.Value.Int32 : a.Value.Single
    )));
};

Thanks guys. I still need:
1. item name (localized)
2. item type (amu/ring/belt/boots/...)

[bastiflew]

1. You can extract Items.stl from file, and extract localized names.
Or from memory with SNO, but I don't know exactly how to get the stringlist link.
2. Item type can be readed from GameBalance, I don't know exactly how to read that with Enigma's framework.
