3D Survival Horror Game Design

Create a detailed design document and implementation plan for a 3D survival horror video game developed for PC using Three.js and WebGL. The game is played in first person and takes place inside a maze environment defined by the following matrix representation, where: - 1 = Wall - 0 = Walkable space - 2 = Exit - 3 = Entry "12111111111111111111", "10100010001000100011", "10001000100010001011", "11111111111111111001", "10000000000001111101", "10111011111101000001", "10010010000101111101", "10111110110000010001", "10000010100101011011", "11011110111101000011", "11000010111101111011", "11011010100101000001", "10001000001101111101", "10111110100001001001", "10000010111111011101", "10111110000000000001", "10011111111111111111", "11010001000100010001", "11000100010001000101", "11111111111111111131" Include in your design: - How to render and navigate the maze defined by the matrix in a first-person perspective using Three.js and WebGL. - Player mechanics for movement and interactions within the maze. - Implementation of a hostile shadowy entity characterized as follows: - Completely shadowy appearance - Two distinct white pupils - Behavior: stalks the player only from behind, never appearing directly in front or to the sides. Provide a clear methodology for detecting and handling the entity's position relative to the player, ensuring it follows consistently from behind without surpassing the player. Outline game mechanics such as survival elements, player health, objectives, and how the player can find and reach the exit. Discuss any optimization techniques needed for smooth rendering and gameplay performance. # Steps 1. Parse the maze matrix to generate the maze geometry, mapping walls and walkable spaces accurately. 2. Implement the first-person camera and controls to allow player navigation through the walkable paths. 3. Develop the shadowy entity's AI to track the player's position and move along the maze but strictly from behind. 4. Create visual effects to render the shadowy figure with the specified appearance. 5. Integrate collision detection to prevent the player from walking through walls. 6. Define game state logic to manage player survival, entry point at '3', and successful exit upon reaching '2'. 7. Test and optimize rendering loops, input responsiveness, and entity behavior. # Output Format Deliver a comprehensive, structured design and technical implementation plan in markdown format, including code snippets or pseudocode where appropriate to demonstrate key implementation points. # Notes - Assume Three.js and WebGL are the primary libraries used. - The maze matrix must be interpreted precisely to reflect the game environment. - The shadowy entity's stalking behavior from behind the player is a critical gameplay mechanic. - The output should be suitable for a game developer to start implementation based on the provided design.
