Target Core: Prime Numbers and Lowest/Highest Attributes

[DietAmbrosia]

Hello all! I am making a class based off the Arithmetician class from Final Fantasy Tactics. I had a couple questions regarding target conditions:

1) What tags would allow a skill to target any unit with a level that is a prime number? (i.e., 2, 3, 5, 7, 11, 13, 17, 19, 23, etc).

2) I suspect this one is more challenging... I want to create the following spells:

- Warp: Increases the Agility of the unit(s) with lowest Agility by 25%.
- Dilate: Decreases the Agility of the unit(s) with the highest Agility by 25%.

How would I create a condition that hits the target(s) with the lowest parameters for a specific stat, if at all possible?

I guess an inefficient way would be to simply list all the prime levels outright, up to your game's level cap. Not the most elegant solution, but at least it'd work.

I think it'd be quicker (more "efficient") to list all primes below max level, rather than applying the Sieve every time you use the skill.

Link to Yanfly's Target Core plugin, for reference:

Target Core (YEP) - Yanfly.moe Wiki

www.yanfly.moe

Suggested <Custom Target Eval> notetags, based on the example on that page (untested):

1. Target all alive opponents with prime-numbered level (assuming max level is 99):
   

   var primes = [2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,97];
   foes.aliveMembers().forEach(function(m) {
     if (primes.contains(m.level)) {
       targets.push(m);
     }
   });

   Note that if you want actors to use this skill, you'll need some kind of plugin to add levels to enemies.
   
   
2. Target lowest-AGI alive ally:
   

   var v = 10000;      // min value tracker
   var x = friends.aliveMembers().reduce(function(a, c, n) {
     if (c.agi < v) {  // new min value?
       v = c.agi;      // update min value
       return n;       // store current index
     }
     return a;         // retain index
   }, 0);  // start with index 0
   targets.push(friends.aliveMembers()[x]);

   Target highest-AGI alive opponent:
   

   var v = -1;         // max value tracker
   var x = foes.aliveMembers().reduce(function(a, c, n) {
     if (c.agi > v) {  // new max value?
       v = c.agi;      // update max value
       return n;       // store current index
     }
     return a;         // retain index
   }, 0);  // start with index 0
   targets.push(foes.aliveMembers()[x]);

Hope those work as planned and/or give you enough to work with to figure things out~

In case you're interested, here's a link to some technical info on that "reduce" thing I've used:

Array.prototype.reduce()

The reduce() method executes a reducer function (that you provide) on each element of the array, resulting in single output value.

Thank you so much! These all appear to be working. Do you know if there is a way to make it cycle through all the targets on the battlefield, instead of just friends. or foes. ? I tried using battlers. and members. but didn't have any luck.

Instead of just friends or foes you could try friends.concat(foes) (or vice-versa), e.g.

var primes = [2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,97];
foes.concat(friends).aliveMembers().forEach(function(m) {
  if (primes.contains(m.level)) {
    targets.push(m);
  }
});

concat just merges arrays, details here~

Array.prototype.concat()

The concat() method is used to merge two or more arrays. This method does not change the existing arrays, but instead returns a new array.
