Hello (and sorry for not replying earlier. I’m currently away from home, so I can’t check back quite as often)!

I’ll try explain it in a way that translates well. My answer also depends on whether you are able to write JavaScript plugins.

This “Core” here takes care of loading, running and displaying animations, but it doesn’t know when to start or shorten animations. At least one “Layer” is needed, which triggers animations based on the flow of battle.
(I broke this into multiple parts to make it more affordable, as for many games, just one or two Layers are needed.)

If you’d like to use a premade Layer (without writing JavaScript), I recommend Occasional Battler Flipbooks in most cases. This Layer allows you to have attack, damage, miss, evade and K.O. animations, among others. It can’t distinguish different attacks or damage types, however. It also can’t use contextual parameters like the damage amount. Please check the video on the page to see if this fits your use-case.

To also (or only) add frame-based entrance and idle animations, I recommend Battler Entrance Flipbooks. This Layer starts a single animation along with the battle and can also delay the start of battle until after the entrance animations.

Layers stack, so if you use both, then “occasional” animations can interrupt the idle animation, which then resumes once the “occasional” animation is over. You can see an example of this in the video for Battler Flipbook Sound Effect Events, which is an “Add-In” that adds sound effects to any Layer. You can keep using the default sound effect system too, of course.

I can’t offer translations for the help text, since I can’t afford a professional translation. Machine translation usually doesn’t work well with this kind of technical text.
However, if it would be helpful, I could try to machine-translate the parameters and their descriptions starting around the end of next week. I would be very thankful if you could point out errors, in that case.

If you know how to write your own plugins in JavaScript, you could also create your own Layer plugin instead of using one of mine.

Layers usually have one parameter where rules are entered, like this:

@base TS_Battler_Flipbooks_Core

@param rules
@text Rules...
@desc Animation rules for actors and enemies. The first full match is used.
@type struct<FlipbooksRule>[]
@default []

(The parameter definition of FlipbooksRule and nested structs is included in Battler Flipbooks Core’s source code and must be copied into each Layer.
Most Layers change it somewhat since they have additional conditions or effects.)

Then, in JavaScript, you can parse the parameters and instantiate the runtime like this:

'use strict';

const core = TS_Battler_Flipbooks_Core;

const parameters = PluginManager.parameters(NAME_OF_THE_LAYER_PLUGIN);
core.decodeParameters(parameters);

class MyRule extends core.FlipbooksRule {
    // Custom conditions can be added here.
}

// Hydrate rules from decoded parameter objects:
parameters.rules = parameters.rules.map(dpo => new MyRule(dpo));

// Using a derived runtime with its own name improves error messages:
class MyRuntime extends core.FlipbooksRuntime { }

// Create the runtime instance:
const runtime = new MyRuntime({
    rules: parameters.rules,

    // Other options. I normally have these in parameters, but this are okay defaults:
    enableHomeOverride: false, // Use `true` to use "Home override..." function!

    // These make the Layer work better with some other plugins:
    compatibilityTweaks: true,
    spriteSizeTweak: true,
    spriteSizeTweakUsePoseForPointer: true,
    spriteActorUpdateAppearTweak: true,
    spriteActorUpdateDisappearTweak: true,
});

Then, you can apply the rules at any time (normally in a hook) by calling runtime.apply(battler, {}), which will start applicable animations.

This here is (roughly) what runs the animations in Battler Entrance Flipbooks:

const api = window.MyPlugin = {
    ...core.makeHook(() => api, BattleManager, function setup() {
        const result = api.oldSetup.apply(this, arguments);

        for (const battler of BattleManager.allBattleMembers()) {
            runtime.applyRules(battler, {}); // <- You can pass named parameters here.
        }

        return result;
    }),
};

core.makeHook is a helper function I use to let other plugins easily change my hooks. You can hook an engine function plainly instead like this:

const oldSetup = BattleManager.setup;
BattleManager.setup = function () {
    const result = api.oldSetup.apply(this, arguments);

    for (const battler of BattleManager.allBattleMembers()) {
        runtime.applyRules(battler, {}); // <- You can pass named parameters here.
    }

    return result;
};

(This is quite minimal, but enough to run idle animations. I can make a starter project for layers around the end of next week and upload it here under a permissive license.)
