Debugger panel

Many of Godot's debugging tools, including the debugger, can be found in the debugger panel at the bottom of the screen. Click on Debugger to open it.

The debugger panel is split into several tabs, each focusing on a specific task.

Debugger

The Debugger tab opens automatically when the GDScript compiler reaches a breakpoint in your code.

It gives you a stack trace, information about the state of the object, and buttons to control the program's execution.

You can use the buttons in the top-right corner to:

  • Skip all breakpoints. That way, you can save breakpoints for future debugging sessions.

  • Copy the current error message.

  • Step Into the code. This button takes you to the next line of code, and if it's a function, it steps line-by-line through the function.

  • Step Over the code. This button goes to the next line of code, but it doesn't step line-by-line through functions.

  • Break. This button pauses the game's execution.

  • Continue. This button resumes the game after a breakpoint or pause.

Warning

Breakpoints won't break on code if it's running in a thread. This is a current limitation of the GDScript debugger.

Errors

This is where error and warning messages are printed while running the game.

You can disable specific warnings in Project Settings > Debug > GDScript.

Profiler

The profiler is used to see what code is running while your project is in use, and how that effects performance. A detailed explanation of how to use it can be found here.

Network Profiler

The Network Profiler contains a list of all the nodes that communicate over the multiplayer API and, for each one, some counters on the amount of incoming and outgoing network interactions. It also features a bandwidth meter that displays the total bandwidth usage at any given moment.

Monitors

The monitors are graphs of several aspects of the game while its running such as FPS, memory usage, how many nodes are in a scene and more. All monitors keep track of stats automatically, so even if one monitor isn't open while the game is running, you can open it later and see how the values changed.

Video RAM

The Video RAM tab shows the video RAM usage of the game while it is running. It provides a list of every resource using video RAM by resource path, the type of resource it is, what format it is in, and how much Video RAM that resource is using. There is also a total video RAM usage number at the top right of the panel.

Misc

The Misc tab contains tools to identify the control nodes you are clicking at runtime:

  • Clicked Control tells you where the clicked node is in the scene tree.

  • Clicked Control Type tells you the type of the node you clicked is.
