Creating C# Application

A Unigine-based application can be implemented by means of C# only, without using UnigineScript. This article describes how to create a new Unigine-based C# application in Visual Studio on Windows platform.

Implementation by using the C# language is very similar to C++. Read the Creating C++ Application article to get basic principles.

It is very easy to start your own C# project by using UNIGINE SDK Browser:

1. Open the UNIGINE SDK Browser.
2. Go to the Projects tab and click CREATE NEW.

   

3. Specify the following parameters:

   

   • Project name — specify the name of your project.
   • Location — specify the path to your project folder.
   • SDK — choose the Unigine SDK.
   • API+IDE — choose either of two C# options. Choose C# (.NET Core) to start working with the C# API with the Component System available.
   • Architecture — specify the architecture of your target platform.
   • Precision — specify the precision. In this example we will use double precision.
   Notice

   Read more about these parameters in this article.
4. Click the Create New Project button. The project will appear in the projects list.

   

You can run your project by clicking the Run button.

In this section we will add logic to the empty C# application project.

The following example shows how to rotate the material ball that was created by default in your project.

1. In the UNIGINE SDK Browser, choose your C# project and click the Edit Code button.

   

   Visual Studio will be opened.
2. In Visual Studio, write the following code in your project's AppWorldLogic.cs file.
   Source code (C#)

   using System;
   using System.Collections.Generic;
   using System.Linq;
   using System.Text;
   
   using Unigine;
   
   namespace UnigineApp
   {
   
   	class AppWorldLogic : WorldLogic
   	{
   		// define pointer to node
   		Node node;
   
   		public AppWorldLogic()
   		{
   		}
   
   		public override bool Init()
   		{
   			// find the material ball node by its name
   			node = Engine.editor.GetNodeByName("material_ball");
   			return true;
   		}
   
   		public override bool Shutdown()
   		{
   			return true;
   		}
   
   		public override bool Destroy()
   		{
   			node.clearPtr();
   			return true;
   		}
   
   		public override bool Update()
   		{
   			// set the transformation to the node
   			double angle = Engine.ifps * 90.0f;
   			node.Transform = node.Transform * MathLib.RotateZ(angle);
   			return true;
   		}
   
   		public override bool Render()
   		{
   			return true;
   		}
   
   		public override bool Flush()
   		{
   			return true;
   		}
   
   		public override bool Save(Stream stream)
   		{
   			return true;
   		}
   
   		public override bool Restore(Stream stream)
   		{
   			return true;
   		}
   	}
   }

3. Build your project by clicking Build -> Build Solution in Visual Studio.

   

4. Start your project by clicking Debug -> Start in a proper mode in Visual Studio.
