I want to add a creature to area, but there's no AI script... how can I do it?

[Lord-Jyssev]

hmmm you could do it in dltcep...

[CamDawg]

You mean the area doesn't have a script that you can add the creature spawn? If so, then:

COPY_EXISTING ~arXXXX.are~ ~override~ // the area file
  WRITE_ASCII 0x94 ~arXXXX~ // the name of the new area script
  BUT_ONLY_IF_IT_CHANGES

Areas are stored in save games, so you'll need to have a new game or a game where you haven't visited the area yet to see the effects of the new script.

Thanks. B)

Edit: Anyone knows what is the number of Irenicus' sound file - "Quiet, dog!" (or something like that)?

Oh, great and wise modders... I have other simple question. :^^:

How can I remove creature marked as "SKELDED.CRE" from AR0602... pernamently?

ActionOverride("creaturename",DestroySelf())
I am not sure what the deathvariable of the "SKELDED.CRE" is, though.


What exactly does " BUT_ONLY_IF_IT_CHANGES"? Is this to make sure no already existing area script will be overwritten?

From WeiDU ReadMe:
"True only if the file is actually changed by patching actions. Unlike all other when clauses, this one is evaluated just before the result would be written out to the disk."

[jastey]

That means it would override another already existing different area script name? No way of checking whether there is one already?

[CamDawg]

The convention for area scripts is that they use the same name as the area, i.e. ar1000.are uses ar1000.bcs. If a mod uses something else it's really the modder's fault for causing incompatibilities. You could check and confirm that either the area script is correct or set to none, but it adds a lot of overhead for no gain.

BUT_ONLY_IF_IT_CHANGES is there out of habit.

[jastey]

True, I only had problems to understand the BUT_ONLY_IF_IT_CHANGES command. I think I got it now, thank you!

[CamDawg]

It is also possible to remove a creature from an area using WeiDU patching. If the creature is listed in the .are file you can find out the offsets and DELETE BYTES which will remove the creature that way. Don't forget to modify the offsets that occur after the creature to take account of the bytes you deleted tho. In fact you may be able to simply wipe the bytes clean, but I'm sure some ubermodder will tell me that will corrupt the area or something

You could delete, but it would probably be easier to just set the creature to have no appearance times.

Another way to address this problem, since requiring players to start a new game in order to see mod content isn't always popular, is to place the spawn code in a script that will run, then immediately move the resulting CRE to the proper area. We use this trick to get Keto into the Five Flagons (which doesn't have an area script in its non-stronghold state.) We spawn her in the Bridge District script, then immediately bounce her into the bar. Players don't notice.

Thanks. If you wanna why I asked about it check this demo (it's really twice beta version).

The script was added to AR1203 (Firkraag's lair).

That's what I put in it:

IF
	Global("Dragonslayers","GLOBAL",0)
        Dead("firkra02")
THEN
	RESPONSE #100
  SetGlobal("Dragonslayers","GLOBAL",1)
  CreateCreature("Slayer1",[968.946],13)
  CreateCreature("Slayer2",[898.945],13)
  CreateCreature("Slayer3",[876.1005],13)
END

But the game crash when Firkraag is killed. Something amiss, but what?

Example for Kido:

IF
 Global("KidoExists","AR0510",0)
THEN
 RESPONSE #100
 SetGlobal("KidoExists","AR0510",1)
 CreateCreature("Kido",[757.924],13)
END

You have no area coded, so the game chrashes as it doesn't know where to put the creatures

[hlidskialf]

Actually area globals are no different than regular Global or Local triggers. What's most likely the problem is a bad cre file. Try CLUAConsoling them in one at a time. If they appear and work fine, then you know it's something else.

Edit: For understanding variables try this section of IESDP.

Yep. Slayer2 crashed the game. I do not know why yet. He appers to be fine. If anybody could only look at his cre file...
