I know how to use SetParent and SetParentAttachment in plugins,but i find that there are no attachment point like righthand or RHand in L4D2 common infected and i readlly want to attach something in there hand XD.

So is it possible to use bone as a attachment point in plugins?
I have used Model Viewer to find attachment and bone and i find something like that

PHP Code:

    $attachment "RArm" "ValveBiped.Bip01_R_Finger0" 0.00 -0.00 0.00 rotate -0 0 0 


In developer it said this code shold write in .qc file but i actually have nothing about it.
Very thanks for any help.

You can attach to a "poor" model a fake invisible overlay having desired attachment point, than attach a goal entity to that point.

Example how I did it in one of private plugins:

PHP Code:

bool ParentOverlay(int witch) // adds additional layer since witch itself does not have attachment point on spine
{
    // prevent double overlay
    if ( IsValidEntRef(g_iOverlay[witch]) )
        return true;
    
    int entity = CreateEntityByName("prop_dynamic_ornament");
    if( entity != -1 )
    {
        MoveType mt = GetEntityMoveType(witch);
        SetEntityMoveType(witch, MOVETYPE_NONE);
        DispatchKeyValue(entity, "spawnflags", "256");
        DispatchKeyValue(entity, "solid", "0");
        DispatchKeyValue(entity, "rendermode", "1");
        DispatchKeyValue(entity, "renderfx", "6");
        DispatchKeyValue(entity, "renderamt", "0");
        DispatchKeyValue(entity, "rendercolor", "255 255 255");
        DispatchKeyValue(entity, "disablereceiveshadows", "1");
        DispatchKeyValue(entity, "model", "models/survivors/survivor_teenangst.mdl");
        DispatchSpawn(entity);
        ActivateEntity(entity);
        SetVariantString("!activator");
        AcceptEntityInput(entity, "SetParent", witch);
        SetVariantString("!activator");
        AcceptEntityInput(entity, "SetAttached", witch);
        AcceptEntityInput(entity, "TurnOn");
        SetEntityMoveType(witch, mt);
        g_iOverlay[witch] = EntIndexToEntRef(entity);
        return true;
    }
    return false;
} 


PHP Code:

    int overlay = g_iOverlay[witch];
    
    SetEntProp(weapon, Prop_Data, "m_CollisionGroup", COLLISION_GROUP_DEBRIS);
    SetVariantString("!activator");
    AcceptEntityInput(weapon, "SetParent", overlay);
    //...
    sAttach = "medkit";
    SetVariantString(sAttach);
    AcceptEntityInput(weapon, "SetParentAttachment");
    TeleportEntity(weapon, pos, ang, NULL_VECTOR);
    SetEntPropEnt(weapon, Prop_Send, "m_hOwnerEntity", witch);

i think i need read more document to understand those code,
but anyway,thanks for your help.

I don't think you can find somewhere complete document explaining that stuff. Info is very fragmented. Most things you can found on valve wiki.
Ask, I can answer more or less if I have time.

emmmmmmm,
i haven't test those code yet, maybe i will get some mistakes under.

1.attach an invisible entity(prop_dynamic_ornament) to the main entity.
2.set the invisible entity model with the attachment you want.
3.let your true target attaches to the invisible entity.

Is that right?(ignore other thing like collision or color)

Actually i am afraid that the invisible entity attachmentpoint will be close to the main entity attachmentpoint i want?

For example,i am sure tank has the hand attachmentpoint.
I attach an invisble entity with tank model to the infected first,and then attach a melee to the tank's hand.
It will look like the melee is in the infected hand and will follow the infeted hand bone to move?

Althoght i get an attachmentpoint,it will be useless if it isn't the position i want or don't follow the main entity bone to move,i think.

[Dragokas]

All correct.
It will follow attachment point, not the specific bone.
You may need to adjust accurately the position offset and angle (relative to attachment point) for each weapon in above code in this line:

PHP Code:

TeleportEntity(weapon, pos, ang, NULL_VECTOR); 


To make it accuratelty, personally I wrote menu interface, a bit similar to what is done in Silver's Hats plugin.
It looks so:

Great help! I will try it later.
Perhaps it will be a large project because there are more than ten kinds of Infected in L4D2().
If i need to change every attachment position of every infected awhhhh.

Yeah,i understand what is prop_dynamic_ornament.
It will let the attachment entity move like using the main entity bone.

Something like the first image.

I get my target,but it seem to be trouble to adjust the pos and ang awhhh.

[Dragokas]

Please, don't quote all and every post. It is very hard to read.
And yeah, it is very hard process of adjusting. That's why I proposed to make a menu interface.
You freeze the client, than working with correction of position / angles. It's not fast.
