Custom skill damage calculation formulaVersion: 1.0ßAuthor: Lettuce and YOU!Date: May 14, 2008***Not suitable for those who do not know basic scripting syntax***
Version History
Planned Future Versions
- Version 1.1 will have custom formula for normal attack (though if you study this version, attack formula can easily be changed X_X)
Description
Let you fully customize how skill damages are calculated
Screenshots
Can't post a screenshot for something like this >.<;
Instructions
This is how you do it:
1. Set the base damage of the skill you want to use custom formula with to 9999
2. Set the variance value to something different than others, this will be
used as a reference to the custom formula.
Sorry, typo, should say 9999 in the script comment x_x;;
Example
when 1 #Skill with 9999 base damage AND 1 as variance value will use this formula instead of default one
damage = ( user.spi**2 ) #damage is user's spi squared (50 spi = 2500 damage)
@ignore_def = true #this ignores target's defence
@ignore_guard = true #this ignores guarding mode of target (normally guarding reduce damage by 50%)
**INFO** basic math operator
+ Add
- Subtract
* Multiply
/ Divide
% Modulus; give you the left over value after division (5 % 2
gives you 1 because 5 can be divided by 2 twice with 1 as a
remainder)
** Powering : 5**3 = 5 cubed = 5 x 5 x 5 = 125
Math.exp(x) Exponential : Math.exp(5) = e^5 = 148~
Math.sqrt(x)Square root : Math.sqrt(100) = root(100) = 10
rand(x) Returns random number between 0 and x
.floor Round down number
.ceil Round up number
**Multiplication and division are processed before addition and subtraction!
You can overide this by putting a bracket around addition or subtraction ;P
5*3+2 = 17
5*(3+2) = 15
Lets look at what sort of things you can use:
**user is the one using the skill, self is the target. If the monster is using
the skill, user.hp returns monster's hp and self.agi, return player's agi
user.hp self.hp
user.mp self.mp
user.maxhp self.maxhp
user.maxmp self.maxmp
user.atk self.atk
user.spi self.spi
user.def self.def
user.agi self.agi
user.hit self.hit
user.eva self.eva
and more o.o
Something to be careful of:
- You can use user.level and self.level BUT ONLY if you put
"if user.level != nil" OR "if self.level != nil"
because Monsters DOES NOT HAVE LEVEL! you'll get error if you don't
put that line in there. Same goes for critical
IMPORTANT!!
** total damage MUST be stored in "damage" variable.
** These variables gives you extra control
@varience - value used to derive variance, if you @no_variance is false
@no_variance - set to true if you want fixed value
@is_heal - allows damage to be less than 0. It can still be above 0 and hurt the target though
@ignore_def - ignores target's defense
@ignore_element - ignores element, no bonus or reduction
@ignore_guard - ignore guarding mode, no damage reduction
CUSTOMIZATION BEGINS AT LINE 102!

? This idea was first brought to us by someone on creationasylum AGES ago ?
? So if you're that person, please contact me and I'll add your name ^_^ ?

This script lets you create your own damage calculation formula for skills
The default formula takes the base damage and add 400% of user's ATK and
subtract 200% of target's def. Then apply element, skill variance and guard
status
But here you can make a completely custom formula. :D!
INSTRUCTION
This is how you do it:
1. Set the base damage of the skill you want to use custom formula with to 9999
2. Set the variance value to something different than others, this will be
used as a reference to the custom formula.
Example
when 1 #Skill with 9999 base damage AND 1 as variance value will use this formula instead of default one
damage = ( user.spi**2 ) #damage is user's spi squared (50 spi = 2500 damage)
@ignore_def = true #this ignores target's defence
@ignore_guard = true #this ignores guarding mode of target (normally guarding reduce damage by 50%)
