Chrono API

By
Rolmi

A prerequisite API mod for controlling the flow of in-game time.

Chrono API

This mod was extracted from Deus Chrono-Machina to separate its reusable time-control engine from the original mod's gameplay content. It provides a clean foundation that other mods can use for time manipulation without requiring Deus Chrono-Machina itself.

Features

Set tick rates from 0.0001 to 100 TPS.
Pause and resume time globally or around an entity owner.
Create scoped and bounded time fields for arenas and special gameplay areas.
Whitelist entities so they can continue acting during a time pause.
Record loaded world history and rewind entities, blocks, items, projectiles, inventories, and supported player state.
Includes a Java API for addon developers and gameplay integrations.
Includes extension hooks for custom time-field rules, rewind protection, player state, and client visuals.
Includes client support for frozen entities, interpolation, rewind item trails, and rollback effects.
Provides the /chrono command tree for testing and server administration.

Java API example

import chrono_api.api.ChronoTime;
import net.minecraft.server.level.ServerPlayer;

public void useChronoApi(ServerPlayer player) {
    ChronoTime.setTickrate(8.0F, player);
    ChronoTime.pause(true, player);

    // Later, release this player's field.
    ChronoTime.clear(player);
}

public boolean rewind(ServerPlayer player) {
    return ChronoTime.rewind(
            player.serverLevel(),
            player.position(),
            5.0D,
            player
    );
}
