Item based skills patch

I need help developing a patch or modification that would allow some of my characters to have item based skills. Examples of these skills would be:

Throw - throw shurikens, stars, etc

Quiver - shoot from a selection of arrows

Use - use items only an alchemist can use (like final fantasy X)

These skills would immediately be usable when the items are in the inventory. When the item is not in the inventory, the skill is invisible.

I see two ways of doing this, and I need help either way (or any other suggested ways)

1. Use Yanfly's Skill Cost Requirements script. This is fine, except I need a way to make the skill visible when item is in inventory, and invisible when item is missing.

2. Use a battle command that shows a list of items of a certain type. Instead of using skills, use the items themselves. This would eliminate the need to hide skills when unusable, but has the challenge of making subset items, and only displaying items of that subset. For instance, "Quiver" only shows <arrow> type items, while "Throw" only shows <star> type items..

I would appreciate any help and guidance on such a system. Thanks for your time.

An easy alternative would require the items to be equipped - make that shuriken add the throw skill that it is the cost of, and the skill will only be available as long as the shuriken is equipped.


Everything else is a lot more difficult, but it can be done - for example by having a common event check party inventory after each shop and learn or unlearn skills depending on that.

Thanks for the idea, Andar. I'd like to be able to see a menu list of options to throw.

I think I may have found an answer using the first option I listed. I will need to test though.

Hide Menu Skills

Theoretically I should be able to hide skills based off of custom eval scripts, such as if an item is present in inventory.

Update - I have confirmed the Yanfly Hide Menu Skills will hide the skills on the condition that the item is depleted. As long as all skills are initially learned by default, this system works.
