- Description:
- Hot Reload is a Unity package that allows you to instantly apply code changes without compiling. It works in PlayMode, EditMode, and On-Device, and is trusted by solo indie developers and massive studios alike. With Hot Reload, you can make changes to your C# code and see immediate updates to your game, without requiring a project reload. This means you can work more efficiently and save thousands of hours of development time.
Hot Reload supports a wide range of code edits, including changing the logic of a method, adding new methods, adding new fields, editing existing fields, and more. It also supports async/await, lambda functions, properties, and partial classes.
Hot Reload is a Unity Verified Solution and has been nominated for the Best Development Tool award in 2023. It is available for individuals and small teams, and Unity Pro/Enterprise companies with more than 10 employees require a Business license.
The setup process is easy: download and import the package, run it, and make changes to your code. Hot Reload is compatible with Windows, Linux, and Mac OS, and supports Unity versions 2019.4 to 2023 (alpha).
