DayNight2D Getting Started

Install

1. Place DayNight2D in your project’s Plugins folder.
2. Enable the plugin in Unreal.
3. Restart the editor if Unreal asks.

Create Time Settings

1. Create a DayNightTimeSettings data asset.
2. Configure RealSecondsPerGameMinute.
3. Set the starting minute, hour, day, month, and year.
4. Configure calendar length and day phase start hours.

Use The Time Subsystem

DayNight2D uses UDayNightTimeSubsystem as the global source of truth.

Blueprints can read:

• Current time and date.
• Weekday, month, season, year, day phase.
• Total minutes, hours, and days passed.
• Pause state through save/replication state.

Blueprints can control:

• Pause and resume.
• Time speed.
• Set time/date.
• Advance minutes, hours, and days.
• Skip to morning or a target hour.

First Blueprint Test

1. In a Blueprint, get the world subsystem DayNightTimeSubsystem.
2. Bind to OnHourChanged.
3. Print GetFormattedDateTime.
4. Call SetTimeSpeed to accelerate the test.
5. Confirm output advances without per-frame Blueprint tick.
