Variable Element Resistance and Damage

Hello!

Would anyone be able to help me with a script that would allow element rates given by a state be tied to a variable?

For example, perhaps there'd be the notetag <ElementRateVariable Fire 20>, that would make the afflicted actor's Element Rate for the Fire element equal to [Variable 20]%.

I hope this actually makes sense. Let me know if there's anything you'd like me to try and explain better.

Thank you!

Edit: After a bit more thought, I realized I was over-complicating this, and cleaned up the request.

 

This should be easy enough to do. Does that variable's element rate overwrite the base element rate, or do they multiply together? E.g. if I had an item that changed Fire to 20% and a state with a variable that said it was 50%, the total element rate would be 10%.

 

Assuming I'm understanding how elemental rates work right, having it multiply instead of overwrite would probably allow it to play nice alongside other element rates.

 

Having an element rate tied to a global variable seems like a mess to me.
Just so that we understand, could you give an example of how you intend to use this script?
I may be able to whip something up after work, if someone else hasn't already by then.

 

You can try this; I haven't tested it yet:

This script makes it so that element rates can be tied to a game variable set
via notetags in the item's note field.

You can use notetags in the following note fields:
  Actor
  Class
  Weapon
  Armour
  State
  Enemy

<ElementRateVariable x y>
  where x is the ID of the element and y is the ID of the variable
    OR
  where x is the name of the element and y is the ID of the variable
 
<ElementRateVariable 3 20>
  would set element 3 to be the value of game variable 20
 
<ElementRateVariable Ice 3>
  would set the element called Ice in the database to be the value of
  game variable 3

 
Variables should be set to an integer, e.g. 20 for 20%, 100 for 100%, 5 for 5%

NOTE: You will need to set your variables to the correct amounts at the start,
or else you may have issues with elements not working or returning zero values,
(because the automatic value for variables is 0).

    else
      result = objects_element_rate_vars(item.damage.element_id)
    end
    return rate * result
  end
 
end

 

Thank you for taking on my request

The script doesn't crash on startup, however upon attacking, I get the following error:

Game_Variables:19:in `[]': no implicit conversion from nil to integer, TypeError

In my test, I had a state given to an enemy, with the tag <ElementRateVariable Ice 30>, with variable 30 being 200 for double damage.

Also Rinobi, I'll be sure to edit a more in-depth explanation of what exactly I'm trying to use it for later. Afraid I only had about 10 minutes to test it out before having to go.

Should work this time.

 

Everything seems to be working great now! Thank you!

Seriously though, you've really helped me out with a lot of different features now. Thank you so much!
