How It Works
Getting started with Airplane Escape is easy! The game begins with your jet positioned at the center of the screen, ready for takeoff. Your mission is straightforward: dodge oncoming obstacles while climbing higher and higher. Let’s break down the controls:
Left Mouse Click: Moves the jet up (Ascend to the skies).
Releasing Left Click: Moves the jet down (Descend gracefully back down).
Right Mouse Click: Activate your speed boost and watch your jet flourish!
Keyboard 'P': Pauses and resumes the game.
ESC Key: Exit the game.
The main objective is to see how far you can fly without crashing into any obstacles. As you advance, the challenge grows, with obstacles appearing more frequently and game speed increasing to keep your adrenaline pumping.
Code Breakdown
Now, Let's dive into the code that brings Airplane Escape to life, transforming an intriguing concept into a thrilling gaming experience!
1. Game Initialization
Everything kicks off in the `main()` function, where we set up the OpenGL environment, laying the groundwork for your high-flying adventure. The code snippet initializes various parameters to create a user-friendly window titled "Airplane Escape!" and connects the crucial functions that will guide your play experience, ensuring everything feels seamless and engaging.
int main(int argc, char** argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH);
glutInitWindowSize(SCREENW, SCREENH);
glutInitWindowPosition(50, 50);
glutCreateWindow("Airplane Escape!");
init();
glutDisplayFunc(display);
glutReshapeFunc(myReshape);
glutMouseFunc(mouse);
glutKeyboardFunc(keyPressed);
glutMainLoop();
return 0;
}In this snippet, we establish the environment for all your aerial adventures—exciting, right?2. Jet Movement
Your jet isn’t just a static object; it reacts to your every command! With the `moveJetU()` and `moveJetD()` functions, players can perform ascents and descents with simple controls. When not paused, your jet glides smoothly upward or downward, enhancing the thrill of controlling your flight as you navigate through dynamic skies.
void moveJetU()
{
if (!pause) // Check if the game is not paused
{
plane_mvmt += 0.05; // Move the plane upward
glutPostRedisplay(); // Redraw the screen
}
}
void moveJetD()
{
if (!pause) // Check if the game is not paused
{
plane_mvmt -= 0.05; // Move the plane downward
glutPostRedisplay(); // Redraw the screen
}
}With just a flick of your mouse or a tap of your keys, the jet responds to your commands,allowing for smooth ascents and descents.3. Obstacle Generation
Every flight is a rush of unpredictability with obstacles popping up at random—be it a towering building or fluffy clouds. The `init()` function ingeniously seeds randomness, ensuring that no two play sessions are alike and forcing players to think on their feet as they react to the changing landscape.
void init()
{
srand(time(0)); // Seed the random number generator
int random = rand() % 2; // Generate a random number (0 or 1)
if (random == 0)
{
buildingBlock(); // Generate buildings as obstacles
}
else
{
CloudBlock(); // Generate clouds as obstacles
}}
This random generation keeps each playthrough fresh and exciting, as you never
know what obstacles are coming next!4. Boost Mechanism
What’s a challenge without the occasional burst of speed? When you activate the boost, your jet accelerates, zipping through the air at thrilling speeds. The carefully crafted boost mechanism ensures that the gameplay remains exhilarating while managing the pace to keep the excitement continuous.
if (booster > 0 && boost) // Check if boost is active and booster meter is available
{
b.block_x -= bspd + boost; // Increase speed
booster -= 0.02; // Decrease booster meter
}
else
{
b.block_x -= bspd; // Maintain normal speed
}5. Collision Detection
In this game, you're not just flying; you're maneuvering through a plethora of dangers! The `checkCollision()` function effectively keeps track of potential crashes between your jet and obstacles, helping maintain a suspenseful atmosphere where one wrong move could spell your doom.
bool checkCollision() { if (plane_x + plane_width > obstacle_x && plane_x < obstacle_x + obstacle_width && plane_y + plane_height > obstacle_y && plane_y < obstacle_y + obstacle_height) { return true; } return false; }
6. Score Calculation
As you conquer the skies, your survival translates into points! The `updateScore()` function embodies this addictive gameplay mechanic, rewarding players with points for staying alive, while ramping up the challenge by increasing speed every 50 points to keep the adrenaline flowing.
void updateScore() { score += 1; if (score % 50 == 0) { bspd += 0.02; // Increase game speed every 50 points } }
7. Game Over Logic
Every journey has its end, and when it comes to game over, the `gameOver()` function delivers a retro-style scoreboard that makes you reflect on your performance before you exit. The thrill of competing for a high score is rewarding, urging you to jump right back in and try for a better flight on your next attempt!
void gameOver() { cout << "Game Over! Your score: " << score << endl; exit(0); }
With these mechanics combined, Airplane Escape offers not just a game, but an exhilarating journey filled with challenges, surprises, and endless fun—each play is a chance to refine your skills and test your limits!
