An easy way to disable all Debug Log functions in Unity is to simply turn off the Unity Logger. This works by setting the Log Enabled property of the Logger to false. This works in the Editor and in standalone builds of the project and prevents all debug messages from being called, saving performance and avoiding garbage.

Print is a built-in method that prints a message to the Console in Unity in almost the exact same way as Debug Log does. Like this: The only real difference is that print is a little easier to write however it doesn’t support an object context in the same way as Debug Log does.

While the basic method of using Debug Log displays a message in the Console, it’s also possible to provide a reference to an Object that the message may relate to. For example, you could pass in a reference to the game object that the script is attached to. Like this:

The Debug Class also provides two methods for displaying visual lines in the Unity Editor as the game runs, which can be useful for visually identifying direction vectors and even connections between objects.
