Weapon casting a random skill (Yanfly Ace Weapon Attack Replacement)

[Aslanemperor 49]

Hey!  I'm not sure how often Yanfly checks their scripts page for questions, so I'm posting this here as well to see if someone knows the answer.  I'm wondering if there's a way to have the script choose a skill within a range instead of a single skill.  This is for my wizard character, who is using something like the Caster weapon from Outlaw Star.  Anyway, hopefully someone has a clue on this topic.

This will do a range 10, 15. Working on having it as a list. 1, 2, 3, 4 etc.

Added list option

updated script

[Aslanemperor 49]

So, I'm completely untrained when it comes to code.  Where do I add this in?  Honestly, I was hoping it would be as easy as a damage formula, maybe a single line of code.  Is this the only way to get that effect?

[roninator2 258]

As with all scripts they go in the script editor.

You can't expect to have a modification to a script function without putting in some code.

Damage formulas can not make changes to the skill used in that manner. As the name says, it's the damage formula, not skill selection formula.

You said you wanted a range. How did you expect to have that work? I'm asking because maybe you have an idea that is possible.

I've almost got the list selection working.

One thing I've noticed though is that you will not be able to attack unless you have enough tp for the skill. So having a random selection will sometimes cause the actor to not act or not allow you to select attack.

[Aslanemperor 49]

I kinda figured it would go into the script editor.  I was more wondering if it should be by itself, or is this an edit to the Yanfly script I'm asking about.  I kinda hoped that maybe there was some bit of shorthand the same way as when I have my character talking I can use "/N[001]" to make the speech editor understand I want to list the player's chosen name in that spot.  Wishful thinking, I guess.

 

Currently, the Yanfly script works so that you simply put "<attack skill: ###>" and whatever number you put in becomes the number for the attack.  I was hoping that someone knew a way to make that be a range of skills instead of just one specific one.

TP wouldn't be an issue with what I was thinking of.  I was thinking of a range between skill number slots because I tend to keep my skills very orderly.  I wanted to make it so that the player could equip different versions of the gun and how strong the spell cast would be somewhat random when using the gun.  I don't want to make it to complex and I don't want to work outside the Yanfly script if I can help it.  This is only my second game, and I'm trying to take things slow getting used to scripts.

The code I posted previously and now the finished product will do just that.

The choice of TP swap and MP swap is an option.

Yes. require yanfly's script.

It's your choice to use as little or as much as you want for the note tags.

[Aslanemperor 49]

Nice!  the edit makes things much clearer, thanks!  I think this solves my issue!
