When building games with Godot Engine, the editor provides most of what you need. But once projects grow beyond small prototypes, you start repeating the same patterns over and over:
-
writing the same controller logic
-
rebuilding the same debug tools
-
copying utility functions between projects
-
solving the same small problems again and again
Over time, most developers end up building a personal toolkit.
This series is mine.
Instead of keeping these scripts buried in old projects, I’m documenting them here so they can be reused, improved, and critiqued.

The Goal of This Series
The goal is simple:
Provide small, practical scripts that can be copied into a project and used immediately.
No plugins.
No dependency chains.
No framework to install.
Just scripts that solve common problems.
Each script is written to be:
-
Self-contained – minimal setup required
-
Configurable – exposed variables in the inspector
-
Readable – so developers can modify them easily
-
Reusable – drop them into different projects
Most of these scripts exist because I (and all other contributors) got tired of writing the same thing repeatedly.
What You’ll Find in This Toolkit
The scripts in this series are grouped loosely by purpose.
Controllers
Controllers are the first group in the series. They provide ready-to-use movement systems for common gameplay perspectives.
Examples currently available:
-
First Person Controller (FPC)
A simple character controller with mouse look, jumping, and acceleration. -
Third Person Controller (TPC)
A more complex system with orbit camera, spring arm collision, and smooth character rotation.
These scripts focus on being easy to understand and easy to modify, not on building a massive “universal controller framework.”
Debugging Tools
During development, you often need ways to inspect your world that normal gameplay doesn’t allow.
One example already included:
-
Debug Camera
A free-flying camera that lets you explore the scene during runtime.
Tools like this are extremely useful for:
-
inspecting level geometry
-
testing environments without a player controller
-
quickly navigating large scenes
Utility Scripts (Planned)
Future articles will expand the toolkit with additional helpers, including things like:
-
scene and node manipulation tools
-
reusable math helpers
-
debugging utilities
-
small quality-of-life scripts for development
These will appear gradually as they’re documented and cleaned up.
How Each Article Works
Every script in this series gets its own article.
Each article explains:
-
What the script does
-
How to use it in a project
-
How the code works internally
The explanations intentionally walk through the code (line by line wherever necessary) so that even developers new to scripting can follow what is happening.
If you just want the code, you can copy it directly.
If you want to modify it, the explanation should make that easier.
These Scripts Are Not Perfect
None of these scripts claim to be the “correct” or “best” implementation.
They are simply practical implementations that work well in real projects.
There are always trade-offs in game programming:
-
simplicity vs flexibility
-
performance vs readability
-
general systems vs specialized scripts
Different developers will make different decisions.
Because of that, critique is welcome.
If you see something that could be improved, simplified, or made more robust, that feedback is valuable.
Why Share Them?
Two reasons.
First, writing documentation forces code to become clearer.
Explaining a script often reveals places where it should be improved.
Second, many small tools never get shared because they seem too trivial. Yet those tiny tools are often the ones developers use the most.
A well-designed 20-line script can save hours of work.
What Comes Next
More scripts will be added over time.
Future additions will likely include:
-
additional controller types
-
camera systems
-
development utilities
-
reusable helper functions
As the toolkit grows, this page will act as the index for the entire series.
