AISetClass(actor, ai);

When the ai file is set, is it based on the difficulty? For example, if I had "ai aifile=aistormie.ai" as a symbol, and I used "AISetClass(getSenderRef(), aifile)", would it give the sender "aistromie.ai2" on hard, or will it only give "aistormie.ai"?

[edit] I forgot. Shoot. While you're here, can you please tell me where Seifer's POV weapon cog is available?

Thanks.

From my experience of working with AI files, I believe that:

*.ai0 = easy
*.ai = medium
*.ai2 = hard

Ideally, you should provide all three for a custom level because the engine selects the appropriate AI file for the selected difficulty level (that the player chooses when starting JK). If however you only supply one AI file, no matter which difficulty level you choose, it will use and apply that one ai file as the default for that actor's AI class.

Hope this information helps [http://forums.massassi.net/html/biggrin.gif]

PS: I do love tweaking the AI files - it's not really apparent in JK but the advances in MotS AI (coupled with COG's advances - "AIGetAlignment()" and similar verbs) are fairly numerous and provide a lot more interactive possibilities - the first level of MotS, fighting alongside your companions, still being one of my favourite levels [http://forums.massassi.net/html/wink.gif] [http://forums.massassi.net/html/biggrin.gif]

Yeah, LJ, but I'm changing the AI after startup via cogverb ant the top of this page. I'm asking if that will give the actor the ai file basedon difficulty.

For example, the symbol value is "blah.ai" and the difficulty is easy. Even though the value specifies the ai file for medium diff., will the JK system give the actor "blah.ai0" instead because the difficulty is on easy? I hope you understand this question.

And I'll ask ruthven about the cog.

Why don't you just check the diff settings and apply the proper ai file manually?

I didn't see the GetDifficulty() verb before. I must've just overlooked it or something...

Arrrggghh! Just my luck.

I have this code, and the italicized parts don't seem to be working right (particularly concerned with disabling their ai for a moment so they can reload).

Just a cursory glance, but in the if statement body of your "fire" message, you have ISetMode (params) rather than AISetMode (params) [http://forums.massassi.net/html/wink.gif] - it could be something as trivial as this... [http://forums.massassi.net/html/tongue.gif]

I suspect that there's something more afoot with the cog script, but I can't test it at the moment... [http://forums.massassi.net/html/redface.gif]. If you try some print statements, what does it tell you the values of the parameters for your setThingUserData() verbs are?

Hope this (somewhat) helps [http://forums.massassi.net/html/biggrin.gif]

It always prints '-1' for the output statements that print the user data. I'm gonna try a slightly different approach to the output though: concatenation. I should learn those verbs and use it more often for these types of situations [http://forums.massassi.net/html/rolleyes.gif] .

ISetMode()? Oops. must've somehow deleted it accidentally when adding the [ i] and [ /i] tags. [http://forums.massassi.net/html/redface.gif] Because it's not ISetMode in the cog; it has the preceding 'A' (damnit how I wish that was the problem!).

[edit]
Updated code again. In the timer[id=0] code, it only sets the userdata of the reeyee to 32 once in a while (once in every 5-10 reloads), and I have explicitly stated in the command to set it to 32. Every other time it leaves the userdata unchanged [http://forums.massassi.net/html/confused.gif] . And in the "fire" message, it always gets '0.000000' for the userdata even when it was just set to 32 in the "timer" message WTF is up with all that?

I did find an error I made: I was setting (clearing) the 0x1000 ai mode flag at the same time I was clearing (setting) the 0x2000 flag. I should have been setting (clearing) them at the same time as each other. That has been fixed in the code, but it still is having no effect at the moment.
Note:
0x1000 -- Actor will not attack
0x2000 -- Actor's AI is disabled

I also made the cog change the ai of the reeyee to a dummy one that has params that make the actor never fire. The ai doesn't change. Seems very little of the stuff in this frigging cog works. [http://forums.massassi.net/html/mad.gif]
