Using Items instead of JP on specific note tag

Hi all,

So I've been playing with Yanflys Skill Learn and Job Point Plugins to create Stat Upgrades with increasing costs, however I do not want to use job points to buy the stat upgrades. I want to purchase the stat upgrade skills using an item and I want the item to increase by one each time the skill is bought, just like the following note tag does with job points. I just want it to use items.

<Custom Learn JP Cost>

// Set the param ID of the stat you wish to adjust.

var id = 0;

// Default the user's upgrade parameter times to empty.

user._upgradeParam = user._upgradeParam || [];

user._upgradeParam[id] = user._upgradeParam[id] || 0;

// Adjust the cost of

cost = user._upgradeParam[id] * 1;

</Custom Learn JP Cost>

I'm not sure everything that needs altered in this note tag but know this should be feasible. The item I'm wanting to use is a soul shard and it's ID is 42.

You can find Yanfly's video for Stats with Increasing Costs here at [embedded media]

Thanks in advance for any help I receive.

That notetag merely changes the JP cost. It's not designed for item costs
However, it is possible to do so using the <Learn Require Eval>, <Learn Cost Eval> and <Learn Custom Text> notetags
I'm still learning javascript, but here's the gist of what you should do:

1. In <Learn Require Eval> notetag, check whether the item is present and enough. Something along the lines of
var cost = user._upgradeParam[id] + 1;
value = $gameParty.numItems($dataItems[42]) >= cost;
Where cost is the item cost of said upgrade

2. Add a line in <Learn Cost Eval> to consume the item, just before the line where it said user._upgradeParam[id] += 1. Something along the lines of
var cost = user._upgradeParam[id] + 1;
$gameParty.loseItem($dataItems[42], cost);

3. Add <Learn Custom Text> notetag to inform the player about the item cost.

@mmgfrcs Thanks!

I knew it should be possible. Unfortunately I've already got everything working using events. It is nice to know that if my eventing fails I can always attempt this method though.
