In Unity, there are two primary rendering components: The Mesh Filter, which stores the mesh data of a model, and the Mesh Renderer, which combines the mesh data with materials to render the object in the scene. Finally, a UV Map maps a material to an object, specifying how textures wrap around the shape. So a mesh’s data also includes its normals, which are vectors that determine which way a particular triangle is facing, and thus how light bounces off of it.

The invisible lines that connect these vertices form triangles, which define the basic shape of the object.īut in addition to the shape, the engine needs to know how to draw the surface of the object. A mesh is like a net of points, or vertices. The shape of a 3D object is defined by its mesh. Time to start with the basic vocabulary of 3D rendering.

You can download the latest version of Unity here. You need to have at least Unity 2019.1.3 installed. If you need to brush up on these topics, check out Introduction to Unity UI and Introduction to Unity Scripting first. To use the encoding settings as configured for your operating system, specify the Encoding.Default property for the encoding parameter.Note: This tutorial is intended for users who are familiar with the Unity editor and have some experience with C# programming. The file handle is guaranteed to be closed by this method, even if exceptions are raised. How to: Read and Write to a Newly Created Data Fileįile.WriteAllText(path, createText, Encoding.UTF8) įile.AppendAllText(path, appendText, Encoding.UTF8) įile.WriteAllText(path, createText, Encoding.UTF8)įile.AppendAllText(path, appendText, Encoding.UTF8).Use the ReadAllText(String, Encoding) method overload when reading files that might contain imported text, because unrecognized characters may not be read correctly. Encoding formats UTF-8 and UTF-32 (both big-endian and little-endian) can be detected. This method attempts to automatically detect the encoding of a file based on the presence of byte order marks. This method opens a file, reads all the text in the file, and returns it as a string. ' This text is always added, making the file longer over timeĭim appendText As String = "This is extra text" + Environment.NewLineĭim readText As String = File.ReadAllText(path) ' This text is added only once to the file.ĭim createText As String = "Hello and Welcome" + Environment.NewLine String readText = File.ReadAllText(path) ĭim path As String = "c:\temp\MyTest.txt" String appendText = "This is extra text" + Environment.NewLine This text is always added, making the file longer over time String createText = "Hello and Welcome" + Environment.NewLine String path = This text is added only once to the file. In this example a file is created, if it doesn't already exist, and text is added to it.

The following code example demonstrates the use of the ReadAllText method to display the contents of a file. The caller does not have the required permission.
