Optional Game Creator 2 Integration

Overview

Environment System is a lightweight Unity module for handling time of day, weather, skyboxes, and storm effects in a reusable workflow. It works as a standalone system and also includes optional Game Creator 2 integration through ready-to-use instructions, conditions, and triggers.

Positioning

Standalone environment system for Unity with optional Game Creator 2 integration.

Suitable for:

• projects that need a simple day/night cycle

• projects that need weather presets and ambient changes

• projects that want a quick demo-ready setup

• Game Creator 2 projects that want visual scripting integration

Features

• Day/Night cycle with automatic time progression

• Sun rotation and light intensity control

• Ambient light and fog updates based on time

• Weather system with configurable weather types

• Weather presets for fog, ambient color, VFX, and audio

• Optional storm lightning controller

• Smooth weather transitions

• Standalone runtime system with optional Game Creator 2 instructions, conditions, and triggers

• Demo scene helpers and simple auto-generated demo UI

Installation

Place the module folder inside your Unity project:

Assets/Plugins/rezus13/EnvironmentSystem/

Requirements:

• Unity

• Game Creator 2 only if you want to use the included GC2 integration

Setup

1. Create a new GameObject in your scene.

2. Add the EnvironmentSystem component.

3. Configure the Time Of Day and Weather manager settings in the inspector.

4. Assign a directional Light as the sun if you want day/night lighting control.

5. Create one or more WeatherPreset assets and assign them to the Weather Manager.

6. Optionally assign weather VFX and loop audio through the preset and manager settings.

7. Optionally add LightningController for storm flash effects.

8. Optionally use EnvironmentDemoSetup and EnvironmentDemoUI for a quick test scene setup.

9. Use the included Game Creator 2 instructions, conditions, and triggers in your visual scripting logic.
