How to use

As new project

The repo itself is a ready to use Godot project.

Just download it and import as new project.

Simple character with script for movement is included.

Add to existing project

• Select your main scene Node2D object
• Attach script to it
• Copy code from game.gd and paste it to your editor
• Create "light" texture. See example: Light.png
• Edit code as you want
• Add Sprite2D to scene. This will be your fog
• Disable "Centered" property under Offset tab on your fog object
• Select fog object, open Material, click new CanvasItemMaterial. Click on it, set Blend mode property to Multiply

By default, it requires CharacterBody2D object.

Check _process and _input functions if you want to adapt the code for your project.

⚠️ Warning

_process function is using a .get_input() method which is declared in player.gd example.
