This script allows you to assign hp cost to skills. This means that you can make it so that a skill can hurt (or heal) the user when he casts it.
Features
- Allows skills to have an HP basic cost, as well as a percentage cost
- Very intuitive configuration; it is easy to set up
Instructions
See inside the header for instructions

#-----------------------------------------------------------------------------------------------------------------------
# For each skill to which you want to assign an hp_cost, set it up like so:
# when skill ID
# cost = <the amount of HP that you want to subtract from the user. If the number is
# negative, then the user of the skill will be healed by that amount>
# percent = <the percentage of max HP you wish to subtract from the user. If negative,
# then the user of the skill will be healed by that percentage>

# There are a couple of examples below. Feel free to delete them once you understand

EDIT: I guess not! XD It only works for the user. Oh well. Could come to use sometime.

And also, you aren't able to disable the skill easily if the hero doesn't have enough HP to cast it through events. It's a huge pain. With scripts, it simply doesn't allow you to use the skill if you don't have enough HP to do so.

Yea. but I wonder we can modify the script to do percent instead.

I couldnt get it working on there for some reason. If there is a patch to make it work, or if you know it doesn't work, please get back to me on this one.
Thanks a lot. Jesse
Ps. You have made all of my favourite work. (Not a big Yanfly fan, not saying Yanfly is bad, just an opinion)

EDIT::
I just downloaded and tested - it worked for me - the HP was reduced, though there was no damage popup.

I got an error when using this script. The error comes when I attempt to use the skill of a hero who does not have any skills yet.
line 61: NoMethodError occurred.
undefined method 'hp_cost' for nil:NilClass
Thanks a bunch!

I was attempting to make an attack that Drained his health and healed all the allies.
I made another attack that damaged all enemies and drained 10% of his Maximum HP, and it took way more than 10%. I've tried placing the script, above, below, all around and upside down in my list of scripts, and still doesn't seem to work. Any idea? I love this script and have a character in my RPG completely based around his skills functioning like this. I'm also not a complete newbie when it comes to editting scripts and customizing them a bit, so I do not think that is the issue. You placed a pretty easy to follow example in the script itself.

EDIT::
Alright, I did a quick and messy "fix" and it is now in the first post. It should fix the initial problem, which was that I was subtracting the HP every time the skill hit a target. So 3 targets meant 120% instead of 40%. However, I haven't tested the new fix so I might have screwed up with syntax or any other number of reasons it's dumb not to test things.
Also, now it really might not be compatible with Tankentai, as I directly alias a method in Scene_Battle, which may operate unexpectedly now. So test it out in a new project and see if everything is dandy before putting it in your main project. If I created an incompatibility or created a new error, just let me know and I will address the problem more fully once I have time.
