This is the source code of most of my game, "The Creature of Chaos", in "library" form, licensed under LGPL v3. Contains classes and definitions designed to build a roguelike first-person shooter. Compatible with Godot 3.5.

You can check out the game utilizing this on Steam and Itch.io, as well as The "template" project

The project was designed with loading swappable "content pack" folders. Think Quake's mission packs or Doom's WADs. These are subfolders under the "content" directory. By design, classes from this library will try to load assets from there. Currently used path is defined in Base/System/_Globals.gd as content_pack_path. This also means that defining file paths for Base classes should be done in format relative to content_pack_path. For example, for MapGenerator to load floor material from file "Content/example/floor.tres" you need to set

• in _Globals.gd content_pack_path = "res://Content/example" and
• in MapGenerator floor_material_paths = ["/floor.tres"]

• KinematicActor: pushable kinematic node depending on external forces (getting pushed by damage, standing on platform, etc.). Common handling for Player and Enemies
• First-person player movement: running, walking, jumping, crouching, swimming, climbing ladders, mouse look, teleporting on command, and when the player falls out of the map
• PlayerResources: keeping track of player's variables, taking and giving resources, resource limits and upgrades, optional time-limit, and progress variable tracking

• HintBoard: a "tutorial" object, displaying hints in-game world

• Pause / Game Over Menu
• Difficulty selection and customization menu
• Options Menu: graphics settings (window / fullscreen display, resolution scale, vsync, antialiasing mode, sharpening strength, toggling dynamic shadows, toggling ambient occlusion, setting player's field-of-view), audio (master / music / sfx volume),
• Control customization menu allowing setting keybinding for most in-game functions
• Saving and loading: player's progress, player's settings, player's controls, player's "custom map" mode settings

• EnemyAI: customizable AI state machine script; movement depending on if player is in line-of-sight, 3 movement options (standing, wandering, chasing player), attacking using selected means (melee / projectiles / 'boomerangs'), playing sfx, spawning 'gibs', giving player resources on defeat
• KinematicEnemy: interface and base scene for moving enemies
