Local testing using builds

An easy way to test your game locally is to simply create a build, and open several instances of it.

You can also connect the Editor alongside the builds, with the extra benefit of being able to inspect the hierarchy and the state of its GameObjects.

Pros

• Easy to distribute amongst team members and testers

• Well-understood workflow

• Can test with device-specific constraints (smartphones, consoles, ...)

Cons

• Not the shortest iteration time, as you need to continuously make builds

• Harder to debug on the builds (requires custom tooling on your side to do so)

Read Unity's documentation on how to make a game build.

Make sure you've read through Local Development and have started a Local Replication Server.

Requirements

Go to Project Settings > Player and:

• Enable Run in Background.

• Set to Always allowed.

• Disable Force Single Instance.

• (Optional) Set Fullscreen Mode to Windowed

• (Optional) Enable Resizable Window.

Testing Time

When the build is done, start two or more instances of the game. You can also test entering Play Mode at the same time.

• Click Connect in the connection dialogs on both instances. Now, try focusing on one and using WASD keys. You will see the box move on the other side as well.
