Implementation

Let's delve into the implementation details of the Highway View project, where we begin by including the necessary libraries and initializing OpenGL settings to kick off the core functionality.

To effectively manage the movement of cars, clouds, and other elements, we define several global variables:

float moveCar1 = 0.0f; // Position of Car 1

float moveCar2 = 800.0f; // Position of Car 2

float moveBusUp = 270.0f; // Vertical position of the bus

float move_cloud = 0.0f; // Cloud movement position

bool gameOver = false; // Game state variable

1. Creating the Main Road

The primary road in the simulation is a crucial feature, constructed using a simple polygon that outlines its shape. This foundational aspect allows for a realistic representation of the highway:

void DrawMainRoad(){
    glBegin(GL_POLYGON);
    glColor3f(0.2, 0.2, 0.2); // Dark gray color for the road
    glVertex2i(0, 200);       // Bottom left corner
    glVertex2i(800, 200);     // Bottom right corner
    glVertex2i(800, 400);     // Top right corner
    glVertex2i(0, 400);       // Top left corner
    glEnd();
}

In this function, the `DrawMainRoad` method defines the road using defined coordinates and colors, providing a solid ground for the animated elements above.

2. Drawing Road Dividers

To maintain visual order on the road, the system implements dashed lines to function as lane dividers:

void DrawDividers(){
    glColor3f(1, 1, 1); // White color for the dividers
    for(int i = 0; i < 800; i += 50){ // Creates dashed lines every 50 pixels
        glBegin(GL_POLYGON);
        glVertex2i(i, 295);
        glVertex2i(i + 30, 295);
        glVertex2i(i + 30, 305);
        glVertex2i(i, 305);
        glEnd();
    }
}

This function systematically creates white dashed lines in the middle of the road, enhancing the realism of the driving experience.

3. Drawing Trees and Grass Field

The simulation is further enhanced with lush green fields and artistically styled trees lining the highway:

void DrawGrassField(){
    glBegin(GL_POLYGON);
    glColor3f(0, 0.60, 0); // Bright green color for grass
    glVertex2i(0, 0);      // Bottom left corner of the grass field
    glVertex2i(800, 0);    // Bottom right corner of the grass field
    glVertex2i(800, 180);  // Top right corner
    glVertex2i(0, 180);    // Top left corner
    glEnd();
}

This function creates a vibrant green field, adding depth and a touch of nature to the environment.

4. Animating Clouds

Giving life to the sky above, the clouds are creatively animated using circular shapes that move seamlessly across the screen:

void DrawCloud(){
    glColor3f(255, 255, 255); // White color for clouds
    draw_circle(100 + move_cloud, 730, 33); // Main cloud body
    draw_circle(55 + move_cloud, 730, 23);  // Overlapping smaller cloud
    draw_circle(145 + move_cloud, 730, 23); // Overlapping smaller cloud
}

The clouds are created using circles that move fluidly across the sky, contributing to the overall dynamics of the highway view.

5. Moving Cars and Bus

Vehicle movement is accomplished by applying translation transformations to enable smooth motion across the highway:

void DrawCarOne(){
    glPushMatrix();
    glTranslatef(moveCar1, 0.0f, 0.0f); // Translate the car's position
    positionOfCarOne = 120 + moveCar1;  
    glBegin(GL_POLYGON);
    glColor3ub(204, 204, 0); // Color for the car
    DrawBodyOfCarOne(); // Custom function to draw car body
    glPopMatrix();
}

This function employs translation to adjust the car's position smoothly, reflecting realistic movements akin to what one would expect on a highway.

6. Keyboard Controls

User interaction is facilitated through keyboard controls, allowing for dynamic adjustments to vehicle movement:

void keyboard function(unsigned char key, int x, int y){
    if (key == 's') {
        moveCar1 += 5; // Move car 1 forward
        moveCar2 -= 5; // Move car 2 backward
    }
    else if (key == 'x') {
        moveCar1 -= 2; // Move car 1 backward
        moveCar2 += 2; // Move car 2 forward
    }
    else if (key == 'u' && (moveBusUp + 270) < 350) {
        moveBusUp += 1; // Move bus up
    }
    else if (key == 'd' && (moveBusUp + 270) > 245) {
        moveBusUp -= 1; // Move bus down
    }
    glutPostRedisplay(); // Request a redraw
}

With these controls, users can engage with the simulation actively, maneuvering the vehicles and shaping their own driving experience.

7. Continuous Animation with Timer

An animation timer is set up to ensure continuous movement of vehicles and clouds, giving the simulation a dynamic edge:

void update(int value){
    moveCar1 += 2; // Update car 1 position
    moveCar2 -= 2; // Update car 2 position
    if(moveCar2 < 0 && moveCar1 > 800){ // Reset cars after they exit screen
        moveCar1 = -200; // Reset car 1
        moveCar2 = 1000; // Reset car 2
    }
    move_cloud += 0.5; // Move cloud across the sky
    glutPostRedisplay(); // Request redraw
    glutTimerFunc(25, update, 0); // Set timer for continuous updates
}

This function guarantees that the simulation runs continuously, with vehicles and clouds updating regularly, ensuring a vibrant scene.
