How to Run a Unity WebGL Build Locally

Unity is a popular game engine that can be used to create 2D and 3D games. It also has a built-in WebGL exporter, which allows you to export your games to the web. This means that you can create games that can be played in a web browser without having to install any software.

However, if you want to test your game locally before you publish it to the web, you will need to know how to run a Unity WebGL build locally. This is a relatively simple process, but there are a few things you need to know in order to do it successfully.

In this article, we will walk you through the process of running a Unity WebGL build locally. We will cover the following topics:

  • What is WebGL?
  • How to export a Unity game to WebGL
  • How to run a Unity WebGL build locally

By the end of this article, you will be able to run your Unity games locally in a web browser.

How To Run Unity Webgl Build Locally?

Unity WebGL Build is a way to export your Unity game to a web browser so that it can be played without having to install the Unity player. This is a great way to share your game with others, or to make it available on platforms that don’t support the Unity player, such as mobile devices and tablets.

In this tutorial, we will show you how to run a Unity WebGL build locally on your computer. This will allow you to test your game in a web browser without having to upload it to a server.

Requirements

To run a Unity WebGL build locally, you will need the following:

  • A Unity WebGL build
  • A web browser
  • A local server

Unity WebGL Build

The first step is to create a Unity WebGL build of your game. You can do this by following the instructions in the [Unity documentation](https://docs.unity3d.com/Manual/WebGLBuild.html).

Web Browser

Any web browser that supports WebGL should be able to run a Unity WebGL build. However, some browsers may have better performance than others. For best results, we recommend using a modern browser such as Chrome, Firefox, or Safari.

Local Server

A local server is a program that allows you to host files on your computer. This allows you to access your files from a web browser, even if your computer is not connected to the internet.

There are many different local server programs available, such as [Node.js](https://nodejs.org/) and [Apache](https://httpd.apache.org/). For this tutorial, we will use Node.js.

Steps

Once you have all of the required requirements, you can follow these steps to run a Unity WebGL build locally:

1. Install Node.js. You can download Node.js from the [Node.js website](https://nodejs.org/).
2. Install the http-server package. The http-server package is a Node.js module that allows you to host files on your computer. You can install it using the following command:

npm install http-server

3. Create a folder for your game. Create a folder on your computer where you will store your game files.
4. Copy your Unity WebGL build into the folder. Copy the `build` folder from your Unity project into the folder you created in the previous step.
5. Open a terminal window in the folder. Open a terminal window and navigate to the folder where you copied your Unity WebGL build.
6. Run the http-server command. To run the http-server command, type the following into the terminal window:

http-server

7. Open a web browser. Open a web browser and type the following address into the address bar:

localhost:8080

8. Your Unity WebGL build will be displayed in the web browser. You can now play your game!

In this tutorial, we showed you how to run a Unity WebGL build locally on your computer. This is a great way to test your game in a web browser without having to upload it to a server.

How To Run Unity Webgl Build Locally?

This tutorial will show you how to run a Unity WebGL build locally on your computer. This is useful for testing your game before you publish it to a website or app store.

Prerequisites

Before you can start, you will need the following:

  • A copy of the Unity Editor
  • A web browser that supports WebGL (Chrome, Firefox, Safari, Edge)
  • A computer with at least 4GB of RAM

Create a Unity WebGL build

1. Open the Unity Editor and create a new project.
2. Select the WebGL platform from the Build Settings window.
3. Click the Build button to create a WebGL build of your game.

The WebGL build will be saved in the Builds folder of your project.

Configure your web browser to allow local file access

In order to run a WebGL build locally, you need to configure your web browser to allow local file access.

To do this, open your web browser’s settings and find the Security or Privacy section.

In the Security or Privacy settings, look for a setting that allows you to enable local file access.

Once you have enabled local file access, you can open the WebGL build of your game in your web browser.

Run the WebGL build

To run the WebGL build of your game, open the Builds folder of your project and double-click on the index.html file.

Your game will open in your web browser.

This tutorial has shown you how to run a Unity WebGL build locally on your computer. This is useful for testing your game before you publish it to a website or app store.
