Project Summary: C/SDL2 Cinematic Game Template
Project Summary: C/SDL2 Cinematic Game Template with Screen Shake and Audio
# 🛠 Technical Stack
Language: C (C11 standard)
Libraries: SDL2, SDL2_ttf
Libraries: SDL2, SDL2_ttf, SDL2_mixer
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.
Game Loop: Implemented a professional Input → Update → 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.
Delta Time: Fixed time-step used for consistent updates; delta time passed to input handling (currently unused for movement but maintains architectural consistency).
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.
Typewriter Effect: A custom-built system that reveals two messages letter-by-letter.
Message 1: "Hello, human." (large font, 120pt)
Message 2: Multi-line Undertale-themed message about C being the best programming language (small font, 24pt)
Timing: Uses SDL_GetTicks() to trigger a new character reveal every ~333ms for message 1 and ~36ms for message 2 (after 3.5s delay).
Rendering: Uses SDL_ttf for high-quality text. The text is dynamically centered on the screen by calculating surface dimensions relative to window size, supporting multi-line strings.
Memory Safety: Implemented strict null-termination (\0) on text buffers to prevent memory leakage/artifacts.
3. Enhanced Effects & Features
Screen Shake: Triggered on each non-space character beep, providing visual feedback with decaying intensity.
Audio Feedback: Plays a beep sound effect (lowered pitch via mixer frequency) for each typed non-space character.
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).
Player Object: A Player struct exists with position and speed data; arrow key movement is implemented (invisible during intro sequence but functional in background).
4. Game Mechanics & State
Game State Struct: A centralized Game struct that manages loop status, timers, font pointers, audio resources, shake effect, and player data.
Message Transition: Automatically switches from message 1 to message 2 after 3.5 seconds of completing message 1.
Resource Management: Proper initialization and cleanup of SDL, TTF, mixer, fonts, and audio chunks.
# 📂 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.
assets/dialog-beep.wav: Sound effect for character typing.
# 🎯 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.
The game launches a black window, reveals a centered message with a cinematic typewriter animation (two sequences), includes screen shake and audio feedback for each typed character, and allows the user to exit via a timed Escape-key hold. Arrow keys move an invisible player character in the background. The codebase is cleaned, documented, and optimized for macOS.
