Game Programming Basics

1. Introduction

Game programming is the process of creating a video game, which involves writing code that implements gameplay mechanics, graphics, sound, and other elements that make a game enjoyable.

2. Key Concepts

• Game Engine: Software framework designed for the development of video games.
• Game Loop: The core of a game that runs continuously during gameplay, handling updates and rendering.
• Event Handling: Managing player inputs and other events that affect the game state.
• Physics Simulation: Simulating real-world physics to enhance realism in the game.

3. Game Loop

The game loop is a crucial part of game programming. It keeps the game running and processes input, updates game state, and renders graphics.

Game Loop Structure

while (gameIsRunning) {
    processInput();  // Handle user input
    updateGame();    // Update game state
    renderGraphics(); // Render the graphics
}
            

4. Graphic Rendering

Rendering graphics involves drawing the game's visual elements on the screen. This is often done using a graphics library.

Basic Rendering Example

void renderGraphics() {
    clearScreen(); // Clear the screen
    drawSprite(player); // Draw the player sprite
    display(); // Show the rendered frame
}
            

5. Input Handling

Input handling is important for capturing player actions. It can include keyboard, mouse, or gamepad inputs.

Input Handling Example

void processInput() {
    if (isKeyPressed(KEY_UP)) {
        player.moveUp();
    }
    if (isKeyPressed(KEY_DOWN)) {
        player.moveDown();
    }
}
