Peek into the AI for some battle insights.
More detailed violence
We can watch the NPCs take damage and eventually expire, but it’s not exactly super-clear where the damage is coming from. If we poke into the server code to see what’s going on:
DragonsSpine/GameObjects/GameLiving/NPC/AI/AI.cs GitLab
2641
Command.ParseCommand(npc, "poke" , npc.mostHated.Name);
DragonsSpine/GameObjects/GameLiving/NPC/AI/AI.cs GitLab
2647
Command.ParseCommand(npc, "shoot" , npc.mostHated.Name);
DragonsSpine/GameObjects/GameLiving/NPC/AI/AI.cs GitLab
2662
Command.ParseCommand(npc, "kick" , npc.mostHated.Name);
DragonsSpine/GameObjects/GameLiving/NPC/AI/AI.cs GitLab
2666
Command.ParseCommand(npc, "kill" , npc.mostHated.Name);
DragonsSpine/GameObjects/GameLiving/NPC/AI/AI.cs GitLab
2674
Command.ParseCommand(npc, "jumpkick" , npc.mostHated.Name + "/Ki Yah!/!" );
Ok, I think we see a pattern. If we know the NPC’s mostHated, we can be pretty sure that’s who the NPC is attacking. Luckily we’ve already added it to the LiveNPC table in the database, so it’s just a matter of
surfacing it.
Assets/DragonsSpine/DAL/DBNPC.cs GitLab
127
128
129
130
npc.hasMostHated = !(dr.IsNull(dtNPCs.Columns["mostHatedId" ]));
if (npc.hasMostHated) {
npc.mostHatedId = Convert.ToInt32(dr["mostHatedId" ]);
}
Assets/Managers/NpcManager.cs GitLab
129
130
npcScripts[npc.worldNpcID].hasMostHated = npc.hasMostHated;
npcScripts[npc.worldNpcID].mostHatedId = npc.mostHatedId;
Then we make an angry red arrow to point at the object of most hatred:
Wow what a hateful arrow.
We need a way to find the position of our foe:
Assets/Managers/NpcManager.cs GitLab
174
175
176
177
178
179
public Vector3 locateNpc(int npcId) {
if (npcScripts.ContainsKey(npcId))
return npcScripts[npcId].transform.position;
else
return Vector3.zero;
}
And now we can display our hatred:

// display hatred
if (hasMostHated) {
if (myHatred == null ) {
myHatred = Instantiate(hatredPrefab,
Vector3.zero,
Quaternion.identity) as Transform;
myHatred.parent = this .transform;
myHatred.localPosition = new Vector3(0f , 0f , 0.2f );
myHatredRend = myHatred.GetComponent<Renderer>();
}
hatedLocation = npcManager.locateNpc(mostHatedId);
Vector3 hatredDir = hatedLocation - transform.position;
hatredDir.z = 0f ;
hatredDir = hatredDir.normalized;
Quaternion qDir = new Quaternion();
qDir.SetLookRotation(hatredDir, new Vector3(0f , 0f , 1f ));
myHatred.rotation = qDir;
myHatred.localScale = new Vector3(0.3f , 1f , 1f );
myHatredRend.enabled = toBeSeen;
} else {
if (myHatred != null ) {
myHatredRend.enabled = false ;
}
}
Lots of hating going on in the temple today
Cohatred
That’s cool, but the Update method in NpcScript is getting crowded. Can’t we do this in
a cool, coroutine-ish way ?

And while we’re at it, we take advantage of the added efficiency to animate the arrows a bit.
Look how popular the priest is!
