Project Summary: C/SDL2 Cinematic Game Template

🛠 Technical Stack

Language: C (C11 standard) Libraries: SDL2, SDL2_ttf OS: macOS (Homebrew environment) Build System: Makefile using sdl2-config for cross-platform header/library paths.

🚀 Current Implementation

1. Core Architecture Game Loop: Implemented a professional Input \rightarrow Update \rightarrow Render cycle. FPS Locking: Locked at 60 FPS using a dynamic frame-capper (SDL_Delay based on frame start/end timestamps) to ensure CPU efficiency and consistent timing. Delta Time: Implemented time-based calculations instead of frame-based ones to ensure gameplay speed is identical regardless of hardware performance.
2. Cinematic Text System Typewriter Effect: A custom-built system that reveals a message ("Hello, human.") letter-by-letter. Timing: Uses SDL_GetTicks() to trigger a new character reveal every 150ms. Rendering: Uses SDL_ttf for high-quality text. The text is dynamically centered on the screen by calculating the surface dimensions relative to the window size. Memory Safety: Implemented strict null-termination (\0) on the text buffer to prevent memory leakage/artifacts.
3. Game Mechanics & State Game State Struct: A centralized Game struct that manages the loop status, timers, font pointers, and player data. Hold-to-Quit: A safety exit mechanism where the user must hold the Escape key for exactly 1000ms (1 second) to terminate the program. Player Object: A Player struct exists with position and speed data (currently invisible but fully functional in the background).

📂 Project Structure

Makefile: Handles compilation and linking of SDL2 libraries. src/main.c: The entire game logic, fully documented with header and inline comments. assets/font.ttf: External TrueType font used for rendering.

🎯 Current Status

The game currently launches a black window, reveals a centered message with a cinematic typewriter animation, and allows the user to exit via a timed Escape-key hold. The codebase is cleaned, documented, and optimized for macOS.
