Demo Level

A pre-built example level is included with the plugin, that lets you explore and test the time system in action before integrating it into your own project.

Blueprint

World Time Engine UWorldSubsystem

The core of the plugin — a Unreal World Subsystem accessible from Blueprints that manages the global in-game time. It serves as the central hub all other time-related nodes connect to.

Time Info

A collection of read-only Blueprint nodes for querying the current state of time — including the time of day, time expressed in total seconds, whether time is paused, and the current flow speed.

Current Time of the Day

Full Current Time

Full Current Time in Seconds

Is Paused

Get Time Flow Speed

Time settings

Nodes for configuring how time behaves in your world, such as setting the ammount of seconds/minutes/hours your world has and adjusting how fast time flows relative to real time.

Flow Speed

Time manipulation

These nodes let you actively change time at runtime — pause it, jump to a specific moment, add or subtract time, or alter how fast it passes.

Pause Time

Set Time

Add to Time

Subtract from Time

Change Time Flow Speed

Time Events

Blueprint events that fire automatically when time changes — either when the time value is modified (set/add/subtract) or when the flow speed is altered.

Time modification Event

Time Flow Speed changed Event

Timer Trigger

A component that fires an event after a specified in-game duration has elapsed, using the plugin’s time system rather than real-world time — so it respects pausing and speed changes.

Point in Time Trigger

A component that fires an event when the in-game clock reaches a specific moment in time, allowing you to schedule world events with precision.
