🌌 Hollow Knight Movement recreated in Godot 🗡️

⚠️ Disclaimer

To Team Cherry, the creators of Hollow Knight and Silksong: I sincerely apologize for using any extracted sprites or assets from Hollow Knight in this project. 🙏 This is purely a coding exercise to replicate the game's movement mechanics as a learning experience. I am not an artist and have no intention of claiming or redistributing your incredible work. This project is for educational purposes only, and I deeply respect your work. 💖

🌟 Overview

This project is a recreation of the player movement mechanics from Hollow Knight, a critically acclaimed 2D Metroidvania game, built using the Godot Engine (4.x). 🎮 The goal is to emulate the smooth, precise, and responsive movement of the Knight (and inspired by Hornet from Silksong), including features like 8-way movement, jumping, dashing, wall sliding, and wall jumping. This is a coding-focused project to study 2D platformer mechanics, with a focus on achieving the tight, fluid feel of Hollow Knight. 🐞

✨ Features

• 8-Way Movement 🏃: Smooth horizontal movement with input-based direction. (As of the first upload it just goes left/right w/Jump & slide mechanics)
• Jumping 🦗: Precise, snappy jumps with a Hollow Knight-like arc (tuned with gravity ~2000 pixels/s² and jump velocity ~-600).
• Dashing 💨: A quick burst of speed in the facing direction, with a lock on vertical movement.
• Wall Sliding 🧗: Slow descent when holding toward a wall while falling.
• Wall Jumping 🦘: Dynamic leaps off walls with directional pushback.
• Sprite Flipping 🔄: The player sprite flips horizontally based on movement direction.
• Animation System 🎥: State-based animations using AnimatedSprite2D for idle, run, jump (rise/fall), dash, wall slide, and wall jump.
• Camera System 📷: A Hollow Knight-style camera with smooth tracking, room-based limits, and dynamic zoom.

🛠️ Technical Details

• Engine: Godot 4.x (GDScript) 🚀
• Nodes:
  • CharacterBody2D for physics-based movement.
  • AnimatedSprite2D for frame-based animations from sprite sheets.
  • Camera2D for smooth player tracking and room transitions.
• Physics ⚖️:
  • Gravity: ~2000 pixels/s² to match Hollow Knight's snappy fall (approximated from Unity's ~-30 to -40).
  • Jump Height: Tuned to cover ~2-3 sprite heights, similar to the Knight.
• Animation 🎞️:
  • Uses a state machine (enum) to switch between animations (e.g., idle, run, jump_rise, dash).
  • Animations are driven by a sprite sheet (12 FPS for a 12-frame animation lasts 1.0 second, as calculated).
  • Sprite flipping via flip_h for directional facing.
