RMMV Target Core / Chain Lightning (tips & tricks) (Resolved)

[Jay19]

Hello,
I've been stuck for hours on a formula embedded in a script using a plugin from Yanfly
I'm not familiar with scripts and I'm having a hard time configuring it the way I want, even if I think I'm close.
This is a tips & tricks (Chain Lightning), used so that an attack on a single target can reverberate on another target with reduced damage.
Here I want to use it for an equivalent in care.
My problem: the reverb should only hit one of my 4 heroes, but I'm using another plugin that allows me to summon creatures. Those creatures are therefore "friendly targets" but I don't want to include them.

The part of the formula that interests me seems to be this:

var members = allies.aliveMembers();

I would like to be able to specify that the allies who can be targeted are the members of groups 1, 2, 3 and 4.
Is it possible ?
Thanks to those who will help me.

Here's a link to the Tips & Tricks article, for ease of reference:

I've moved this thread to JavaScript/Plugin Support. Thank you.

(You originally posted this in Plugin Releases, which is for sharing plugins you have created.)

Edit: maybe try this?

---

var members = allies.aliveMembers().slice(0, 4);

---

I.e. only look at the first 4 alive members. Technical details here:

Array.prototype.slice() - JavaScript | MDN

The slice() method returns a shallow copy of a portion of an array into a new array object selected from start to end (end not included) where start and end represent the index of items in that array. The original array will not be modified.

caethyril's suggestion will probably take care of you - if that doesn't work, you should say which plugin you're using for summoning more actors and link to it.

Merci beaucoup. Je regarde ça chaque fois que j'ai un moment, je suis au travail en ce moment.
Désolé d'avoir posté au mauvais endroit.

I just tried your formula. She could have been very good, but unfortunately there is a problem. If one of my 4 characters is knocked out, then the next summon in order is included in the formula allies.aliveMembers().slice(0, 4)
Is there another solution than the term "slice"? I'm thinking something like "actorID" for example.
I think we are close to the solution.


Edit : The full formula is:

<Custom Target Eval>
// Adds the selected target to the target list.
targets.push(target);
// Grab the group of alive foes as candidates.
var members = allies.aliveMembers();
// Remove the target from the group of candidates.
members.splice(members.indexOf(target), 1);
// This is the number of extra targets to select with Chain Lightning.
var extraTargets = 2;
// Loop the extra targets.
while (extraTargets--) {
// Grab a random Allies from the alive foes.
var member = members[Math.floor(Math.random() * members.length)];
// Check to see if the member exists.
if (member) {
// Add the member to the group of targets.
targets.push(member);
// Remove the member as a viable candidate.
members.splice(members.indexOf(member), 1);
}
}
</Custom Target Eval>

Hello. I haven't tested this but you can try the following:

var members = allies.aliveMembers().filter(m => m.actorId() <= 4);

i.e. only look at the alive party members whose actor IDs are 4 or less.

Array.prototype.filter() - JavaScript | MDN

The filter() method creates a shallow copy of a portion of a given array, filtered down to just the elements from the given array that pass the test implemented by the provided function.

EDIT:

Spoiler: Notes

• The code will FAIL if you use this skill on enemies. You need to modify the filter() method conditions for that.
• That's a strange skill you're creating since Chain Lightning is normally meant for enemies rather than allies: you're using allies rather than foes. But this is your thread and you can create whatever skill you like.

Thank you for your reply. This matches the idea I had, but unfortunately it doesn't work (syntax error).
In my opinion, the solution should not be very different from what you propose to me.
I also thought we could go through a status effect that would now only be on my heroes, but I don't know if that makes it any easier.

Edit :
The solution was found in private message by Anastasius.
If anyone is interested, the correct code was:
var members = allies.aliveMembers().filter(function(m) {return m.actorId() <= 4});
Topic can be closed, thanks again Anastasius, and thanks to those who tried to help me.

Anastasius's original response used ES6 syntax, which is supported in the latest versions of RMMV. Since you needed the ES5 code, I guess you're using an older version. If that's not deliberate, you may want to consider updating:
