Skill Requirement System 1.1 Options

[icecold49]

I have to say that this is one solid script here. Very nice. Yes, this will definitely come useful in my game. Thanks Queen.

I was wondering how you can make this work with Fomar0153 Blue mage script, after implimenting this script which works fine, my characters no longer learn any skills from enemies.

[Queex]

We both change Scene_Battle.execute_action_skill for different reasons. I'm not entirely up to speed with aliases yet.

Try this and let me know if it fixes it:

Hmm. I don't know about that. I don't get an error my end. Are you using any other scripts that affect Scene_Battle at all? That line is taken unaltered from the default code so I have no idea why it may cause a syntax error.

Erg! That could be it! I am using DerVVulfman's battlebacks script and Lomexi's Battle Theme adjuster... (@_@)!

..I will take a look at it later when I have more time--unless anyone already knows what the conflict might be.

[Queex]

I'm using battlebacks (before this script) without problems. Try moving scripts to after main until the problem goes away.

[aevonhaldy]

Well, I tried taking out my scripts ONE BY ONE until I was left with just TagNote and the Skill Req script, but still the syntax error on the last line. (!)

Finally, I just added "end, end" to the end... and it SEEMS to work (so far so good).

CODE

display_animation(targets, skill.animation_id)
end
end

I have yet to do much with the actual notes, so we shall see... Anyway, thanks for your helpful demeanor! (And I'll be back if I have more problems that I can't fix on my own! But here's hoping I wont have any!)

Regards,
AEVH

[Queex]

Actually- that shouldn't be the last line. I think you may not have copied all of it. Double check that and see if it works.

[aevonhaldy]

Actually- that shouldn't be the last line. I think you may not have copied all of it. Double check that and see if it works.

Hm, yeah, that was one of the first things I checked when I got the script because I thought the end looked funny. --But I can't seem to get the code box to scroll down any further than that line. I often have trouble with code boxes though...maybe because I'm in Internet Explorer....

I don't suppose I could trouble you to post the full code as a TXT file download?

[Queex]

Done- check the original post. That version is the semi-experimental one posted earlier attempting to use an alias, so if there are still problems I'll revert it to the older version.

I intend to upgrade this at some point, after revising TagNote to handle multiple tags of the same type properly.

[aevonhaldy]

Thanks Queex,

You are awesome. I look forward to any upgrades, etc., because this is a really useful script. Thanks for making it.

[Dark Koji]

Yo there!

I noticed that if I set <weapon_type x> to a specified skill, the skill will only work when the "x" weapon is equipped to the character's first weapon slot.

This means that when I shift the same weapon over to the character's shield slot (secondary weapon in this case, since he is allowed to wield two weapons), the skill will still remain disabled - not recognizing the presence of "x" weapon in place.

Any tips on how can I overcome this problem?

[Queex]

I'll fix the script. Tonight, probably. Should be fairly trivial.

Edit: Done. As always, if there are any problems with it let me know. I've cleaned it up a little, too.

Tested it, and it works! Both when equipped with only the weapon on the off-hand, and with two weapons~ Great job as always, Queex!

Oh and, I would like to point out that there is a small bug with <item_consume x>.
You still have to state 'n', as in <item_consume x n> in order for the item to be consumed.

The problem is nothing big, though just wanna let you know it won't be assumed as 1, without an 'n' stated. >_<

[Queex]

Umm, it seems to work for me. As ever, check both it and TagNote are the latest version, other scripts, etc. etc. I'll look into it if the problem persists.

[luciddose]

wow that totally works - thank you, dont know what you did but it works like a charm. You rock! Mucho Kudos!

[Queex]

Bump for newer version.

Now uses the revised TagNote script, has a couple of fixes and includes a facility to make sure required items appear in the inventory when testing battles.

[yuukimaru]

hey is there a way to make one of the requirements being that the actor is under a certain state? like a light arts/dark arts set up if anyone has played FFXI >.>

[hjorverdr]

sorry, i'm having problems with the status on the skills
for example, if a skill causes atk up, there's an error. it is in line 196. i don't know anything about scripting, but i guess that the error is in all this part:

#consume items required
skill_needs = get_tag(skill.note,"item_consume")
if skill_needs != nil
num_items = get_additional_tag(skill.note,"item_consume",2)
if num_items==nil
num_items=1
end
$game_party.lose_item($data_items[skill_needs.to_i],num_items.to_i,true)
end
end
end

even so, it's a great job, man

[thinkabout]

This script looks solid.
I'll look forward <gold_exceed p> and <party_member_present p>

[Queex]

I've been side-tracked by other time sinks recently- most notably getting my car past the MOT- so it might be a while before I make any substantial revisions- although thinkabout's suggestions are definitely good choices for inclusion.

As for hjorverdr's problem, I can't see any way that status effects could interfere. Can you verify that the problem isn't present for a skill with identical requirements but no status effect, and that you're using the latest version in the zip file?
