some useful, reusable godot 4 scripts i frequently refer to
Under the MIT License. Aimed for Godot 4.1.
This contains some useful scripts I used to modularize (is that a word?) attack data for various action based games.
AttackData.gd stores a copy of DamageData.gd and frame data information. DamageData.gd stores a damage (range), knockback, screenshake, and hitfreeze amounts. This is often used with the Events.gd singleton/design pattern also included in this repository.
Hitbox.gd (and Hitbox.tscn) is used to make a reusable scene that most things in your game can implement and have the same functionality. In the future I may update it with some other goodies.
An expansion of GDQuest's State Machine article, to include a version for the Player and for the Enemies. Relatively well commented but likely needs a small amount of adjusting per project.
A Camera2D extension that adds an easy method of doing screenshake. This should be used with the Events.gd singleton to make it seamless to activate across scripts.
A CharacterBody2D extension that relies on the Movement.gd and Stats.gd to make a sort of modular baseline for entities to extend from. Somewhat of an attempt at an ECS in Godot 4? Very useful.
A basic foundation for an Events singleton that has built-in methods/signals for screenshake and hitfreeze, for use with CameraWithShake.gd but can easily be extended.
A custom Node that stores movement information, such as speed, jump height, gravity, friction, acceleration, etc. Can be expanded easily and is recommended to be used with Character.gd.
A custom Node that stores statistical information specific for characters, such as health, knockback damping, etc. Can be expanded easily and is recommended to be used with Character.gd.
ex: I used this in a top-down arena shooter prototype to store and calculate damage upgrades and otherwise.
The state_machine folder of scripts is initially based off of GDQuest's State Machine article, then expanded to include a version for both the Player and Enemies. Should be easy to adjust.
The CameraJuice2D.gd is based off of this YouTube tutorial by TheShaggyDev.
