The error is correct, the only constructor you have has 1 argument, which is a string. It is expecting you to call it like this:

Code: 
this.AddToBackPack( new SpikeHead("Billy Bob Thornton") ); //or whatever name you want to give the SpikeHead.

If you are expecting to add it with just this:

Code: 
new SpikeHead();

Then in the SpikeHead.cs script, you need to create a zero argument constructor. It might look something like this:

Code: 
        [Constructable]
        public SpikeHead()
            : this( "Billy Bob Thornton" )
        {
        }
 
Helpful Little Tip Thanks Lokai. Really like how u explain things have learned a lot from your post :)

The thing is that it is supposed to give the killer's (player) name of the mob.

public SpikeHead(string name)

// ~1_NAME~'s Head on a Spike
 
Anyone can point me somewhere to add the "killer's" name in front of the name like the cliloc: ~1_NAME~'s Head on a Spike


Thanks in advance for any help.
 
You might have to override the OnDeath method. Add something like this:


Code: 
PlayerMobile killer = this.FindMostRecentDamager;

if (killer != null) this.AddToBackPack( new SpikeHead(killer.Name) );
 
Got it to load and compile but it seems something getting in conflict cause when one Spike Head drop it crash the server, maybe you can help ?

Code: 
using System;

Thanks again for your help :)
 
So the server also crashes when you add the spikehead manually without it being dropped?

No but it doesn't either show any name on it. :(

I think I know. You are calling base.OnDeath(c) before dropping the spikehead. The base method is probably clearing the Combatant value. Try using a Try-Catch clause to prevent instability, and drop the spikehead BEFORE you call the base.OnDeath method.

What is a try-catch clause ? :) and thanks for your help.

Code: 
        public override void OnDeath(Container c)
        {
            if (Utility.RandomDouble() < 0.15)
               c.DropItem( new SpikeHead(Combatant.Name) );
            if (Utility.RandomDouble() < 0.25)
                c.DropItem(new MaulOfOrigin());

            base.OnDeath(c);
        }

Even like this it crash.

It look like the server try to double write name on it but i really dont know witch one to remove.

Try-Catch is basic safety net for unknown code problems.

Try { to do something here }
Catch( Exception e) { Print error defined by 'e' but don't crash }

Even like this it crash.
