You can delay an event with a given time. The time however is not exact, particularly if sent to an object far away from the player and when there is a lot of activity happening such as battle. The proccessing of the delayed event is an AI update, and the game gets around to those when it has time. Using the area as the target object helps minimize this.

The code looks something like this:

//I like to declare my event types as constants. Keeps it easy to read. Using the custom event type
//prevents conflicts with other events. Idealy, this should be done in an include file.
const int EVENT_TYPE_MY_DELAYED_EVENT = EVENT_TYPE_CUSTOM_EVENT_1;

...
float fDelay = 5.0;//delay in seconds
event evNew = Event(EVENT_TYPE_MY_DELAYED_EVENT);
object oTarget = GetArea(GetHero());//Could be any target object.
DelayEvent(fDelay, oTarget, evNew);

If you want to pass more detail along with the event, you can set any number of paramaters on the event:

float fDelay = 5.0;//delay in seconds
event evNew = Event(EVENT_TYPE_MY_DELAYED_EVENT);
evNew = SetEventInteger(evNew, 0, 100);//Adding value 100 to index 0
object oTarget = GetArea(GetHero());//Could be any target object.
DelayEvent(fDelay, oTarget, evNew);

Within the taget objects script, you'll need to catch that event and do something with it:

const int EVENT_TYPE_MY_DELAYED_EVENT = EVENT_TYPE_CUSTOM_EVENT_1;

void main()
{
event ev = GetCurrentEvent();
int nEventType = GetEventType(ev);
int nEventHandled = FALSE;

switch(nEventType)
{
case EVENT_TYPE_MY_DELAYED_EVENT:
{
int nValue = GetEventInteger(ev,0);//nValue will be 100, the number we passed in.
//do stuff
break;
}

}
if (!nEventHandled)
{
HandleEvent(ev, RESOURCE_SCRIPT_AREA_CORE);
}
}

If you want a heartbeat, you can delay the same event back to OBJECT_SELF within that script.

Outside of a script, use const datatype variablename = value;



in this case, I had:

const int EVENT_TYPE_MY_DELAYED_EVENT = EVENT_TYPE_CUSTOM_EVENT_1;



My best guess is you don't have any include files above that line, so the custom event 1 constant isn't defined. Try including utility_h at the top and try compiling again.

[_L_o_B_o_]

Try EVENT_TYPE_CUSTOM_EVENT_01

[DavidSims]

It's in events_h, which is included by utility_h.



Could you post the code? My guess is you're doing something else wrong.

The reason your script didn't work until you specified the script is that you are delaying the event on the player, but trying to get the module to pick up the event. Using the player as the object means the event will get routed to player_core.nss unless you specify an override script. It also means that OBJECT_SELF will be the player in the module script when that event runs, which might cause some weirdness if you aren't careful.

It would generally be beter to use a combination of EVENT_TYPE_HANDLE_CUSTOM_AI and EVENT_TYPE_DAMAGED to do what you are attempting.
Make sure to #include "cai_h" and then call CAI_SetCustomAI to something like CAI_DAMAGED under EVENT_TYPE_DAMAGED. Then under CAI_DAMAGED add the retaliate command and  call CAI_SetCustomAI with CAI_IDLE.
