Project Setup

In the previous section, we created a simulation of falling boxes. Jitter includes several default shapes, such as capsules, cylinders, and spheres. These shapes can be transformed and/or combined, and they are already sufficient to represent many types of collidable entities.

In this section, we will add a custom convex shape to the simulation—specifically, the famous Utah teapot. We'll construct this shape from its visual representation by loading a teapot.obj file and using its vertices to create the convex shape.

Requirements​

Install the .NET 9.0 SDK.

Ensure that dotnet is correctly set up by executing the following command:

dotnet --version

Create a New Console Application and Add Jitter and Raylib​

First, create a new directory named "TeaDrop" and navigate into it:

mkdir TeaDrop && cd TeaDrop

Download and unzip the teapot.obj model.

wget https://github.com/notgiven688/jitterphysics2/raw/refs/heads/main/src/JitterDemo/assets/teapot.obj.zip
unzip teapot.obj.zip

Next, create a new console application in this directory and add Raylib-cs and Jitter2:

dotnet new console
dotnet add package Raylib-cs --version 6.1.1
dotnet add package Jitter2

Add the following code to TeaDrop.csproj to allow unsafe code, and to copy teapot.obj automatically to the output directory:

  <PropertyGroup>
    <AllowUnsafeBlocks>true</AllowUnsafeBlocks>
  </PropertyGroup>

  <ItemGroup>
    <None Update="teapot.obj">
      <CopyToOutputDirectory>Always</CopyToOutputDirectory>
    </None>
  </ItemGroup>

You have completed the setup. If you now execute the following command:

dotnet run

Your console should display: "Hello, World!".
