Godot – files in C# in Godot game engine.

Today I tested a new source code with the Godot game engine. The source code recognizes the drag and drop operation for text and image files.

Godot – start with C# in Godot game engine.

You can use easy with the C# with Godot game engine. First, use this web pages to install all you need to run it with Visual Code and Godot game engine: Godot: https://godotengine.org/download/windows .NET Core: https://dotnet.microsoft.com/download .NET Framework 4.7.2: https://dotnet.microsoft.com/download VS-Code: https://code.visualstudio.com After all of these install open the Visual Code and from Extension market… Read More »

Godot – moon shader.

This is a simple tutorial is about how to create a shader moon in time. Into your Godot project add a Sprite to Node2D. Add a New CanvasItemMaterial and then select Convert to ShaderMaterial to the Sprite. Open this shader and fill with this shader source code:
