[System.Serializable]
public class response_changeState :
npcResponse {
3. This class will have two members, an
npcState
enumeration and a refer-
ence to the
npcScript
class. When fired, the script will set the state on the
npcScript
reference to the value set in the local enumeration:
public npcScript.npcState newstate;
public npcScript npc;
4. As with classes that derive from
npcCondition
, we need to override the
abstract method provided in the base class. Instead of
eval()
, we will over-
ride
dispatch()
:
public override bool dispatch()
5. If this response class has an NPC reference, it will set the value of
newState
on to NPC through the
SetState()
setter method that
npcScript
imple-
ments:
if (npc != null)
{
npc.SetState (newstate);
rval = true;
}
return rval;
Congratulations! We now have all the pieces to finally develop an
npcDecisionMgr
class that can tell the NPC to patrol or face the play when close enough. While it's
true that we invest resources into developing a generic decision handling system,
let's see how this pays dividends when implementing the logic in the editor.
