About The Game

Project Crescent Rise is a C++ and OpenGL project built from scratch without a traditional game engine. Its focus is procedural planet generation: each run can produce a different traversable world, while a built-in editor lets you adjust noise, color, quality, and other planet settings live during play.

The current build supports free movement, chat commands, enemy encounters, multiple weapons, JSON save/load for planet presets, and modular script-driven systems for rendering, gameplay, and interactions. The technical goal is to prove that a custom lightweight engine can deliver editable, explorable space environments with strong performance and clear extensibility.

Core Systems

Procedural planets. Each world is shaped through layered noise so terrain silhouettes, landforms, and traversal routes vary from run to run.
Live planet editor. In-game tools let the player adjust noise, color, quality, and other world settings without leaving the session.
JSON save and load. Planet setups can be stored, reloaded, and reused to support quick iteration and replayability.
Script-based architecture. Game objects use modular scripts, tags, and message passing so systems stay decoupled and easier to expand.
Traversal and combat. The current build supports movement, weapons, enemy encounters, and readable hit feedback during fights.
Rendering pipeline. The game uses a custom OpenGL stack for terrain shading, water, skybox rendering, particles, and model handling.
Command-driven tools. Chat commands expose actions like opening the editor, reconnecting, and controlling debug-style functionality.

Enemies

Shard

Ranged enemy that attacks from a distance and adds pressure while the player moves across the planet.
Built on the enemy state system, allowing it to switch between movement, attack, idle, and death behaviors.
Designed to create space-control threats so the player cannot stay still in open terrain for too long.

Slime

Melee enemy that becomes dangerous once it closes distance and prepares a short charge attack.
It briefly stops, turns red, and then lunges, giving attentive players a small reaction window to dodge.
After the charge it has a short recovery period, creating a punish window before it attacks again.

Current enemy renders are pulled directly from the latest provided PNG assets.
