Radius2d

Radius2D is an experimental Physics Engine implementation. It uses Raylib for rendering and Keyboard Input purposes. It was once written in C++, but now have been changed into C# for having better Object-Oriented approach and more sophisticated Vector Calculations. It currently is in the early-development stages. As it now have been shifted into C#, it use Raylib_cs which basically is a C# wrapper for Raylib.

How To Install

To use this, you need the .NET SDK, if you don't have you can download from here.

Install the MIJGames.Radius2D Nuget Package.

Examples

• Cloth Simulation
• Soft Body Simulation

How to Use

You need to include Radius2D and Raylib_cs in your Program.cs file.

using Raylib_cs;
using Radius2D;

Now you need to initialize the Physics Layer

var Layer = new PhysicsLayer();

You can now add Circles, Lines and Springs in the Lists of your Physics Layer,

// Adding Circles in the Physics Layer
for (int i = 0; i < 10; i++)
{
    int posX = Raylib.GetRandomValue(0, 1920);
    int posY = Raylib.GetRandomValue(0, 1080);

    var Circ = new Circle(posX, posY, 0, 0, 15, 20, 1.0f, Color.WHITE);

    Layer.circles.Add(Circ);
}

// Adding Lines in the Physics Layer
var line01 = new Line(Width, 0, 0, 0);
Layer.lines.Add(line01);
var line02 = new Line(0, 0, 0, Height);
Layer.lines.Add(line02);
var line03 = new Line(Width, 0, Width, Height);
Layer.lines.Add(line03);
var line04 = new Line(0, Height, Width, Height);
Layer.lines.Add(line04);

// Adding Springs in the Physics Layer
var link01 = new Spring(Layer.circles[0], Layer.circles[1], 70.0f, 20, 10);
Layer.springs.Add(link01);
var link02 = new Spring(Layer.circles[1], Layer.circles[2], 70.0f, 20, 10);
Layer.springs.Add(link02);
var link03 = new Spring(Layer.circles[2], Layer.circles[0], 70.0f, 20, 10);
Layer.springs.Add(link03);

Now you just need to Update the Physics in the Main Loop

Layer.Update(deltaTime);

And Draw it in Rendering section of the Main Loop,

Layer.Draw();

This is pretty much it, You can have a look at the Examples. There are currently only two examples, Soft Body Simulation in Examples/SoftBodySimulation and Cloth Simulation in Examples/ClothSimulation.

if any kind of help regarding this is needed, you can just mail me.
