## **Enhancements Overview**
1. **Goals:**
- **Definition:** Two `Goal` objects are created representing the left and right goals.
- **Visualization:** Goals are visualized as rectangles on the left and right edges of the screen.
- **Scoring:** When the ball enters a goal area, the opposing team’s score is incremented.
2. **Score Display:**
- **Tracking:** A `score` dictionary keeps track of the scores for the left and right teams.
- **Rendering:** The scores are displayed at the top center of the screen using Pygame's font rendering.
3. **Replay After a Goal:**
- **Triggering Replay:** When a goal is detected, a replay is triggered.
- **Display Message:** A goal message is displayed on the screen for 2 seconds.
- **Reset Positions:** After the replay duration, the positions of the car and ball are reset to their initial states.
## **Detailed Additions and Functionality**
### 1. **Goal Class**
A new `Goal` class is introduced to represent the goal areas.
```python
class Goal:
def __init__(self, x, y, width, height, color, side):
"""
side: 'left' or 'right' to determine which team the goal belongs to
"""
self.rect = pygame.Rect(x, y, width, height)
self.color = color
self.side = side # To assign score correctly
def draw(self, surface):
pygame.draw.rect(surface, self.color, self.rect, 2) # Draw as outline
```
### 2. **Score Tracking and Display**
- **Initialization:**
```python
self.score = {'left': 0, 'right': 0}
self.font = pygame.font.SysFont(None, 36)
```
- **Displaying Score:**
```python
def display_score(self):
# Render the score on the screen
score_text = f"Left: {self.score['left']} Right: {self.score['right']}"
text_surface = self.font.render(score_text, True, BLACK)
text_rect = text_surface.get_rect(center=(WIDTH / 2, 30))
SCREEN.blit(text_surface, text_rect)
```
### 3. **Goal Detection and Replay Mechanism**
- **Checking Goals:**
```python
def check_goal(self):
# Check if the ball has entered the left goal
if self.left_goal.rect.collidepoint(self.ball.pos):
self.score['right'] += 1 # Right team scores
self.trigger_replay(scoring_team='right')
# Check if the ball has entered the right goal
elif self.right_goal.rect.collidepoint(self.ball.pos):
self.score['left'] += 1 # Left team scores
self.trigger_replay(scoring_team='left')
```
- **Triggering Replay:**
```python
def trigger_replay(self, scoring_team):
self.replaying = True
self.replay_timer = pygame.time.get_ticks()
# Display goal message
goal_text = f"Goal for {'Right' if scoring_team == 'right' else 'Left'} Team!"
print(goal_text) # For console debugging
# You can expand this to show on the screen instead
self.show_goal_message(goal_text)
```
- **Displaying Goal Message:**
```python
def show_goal_message(self, text):
# Render the goal message in the center of the screen
message_font = pygame.font.SysFont(None, 72)
message_surface = message_font.render(text, True, BLUE)
message_rect = message_surface.get_rect(center=(WIDTH / 2, HEIGHT / 2))
SCREEN.blit(message_surface, message_rect)
pygame.display.flip()
# Pause for a moment to show the message
pygame.time.delay(2000) # 2 seconds
```
- **Resetting Positions After Replay:**
```python
def reset_positions(self):
# Reset car and ball positions
self.car.pos = pygame.math.Vector2(WIDTH / 2, HEIGHT / 2)
self.car.vel = pygame.math.Vector2(0, 0)
self.car.angle = 0
self.car.image, self.car.rect = rotate_image(self.car.original_image, self.car.angle)
self.car.rect.center = self.car.pos
self.ball.pos = pygame.math.Vector2(WIDTH / 2 + 150, HEIGHT / 2)
self.ball.vel = pygame.math.Vector2(-2, 0)
self.ball.rect.center = self.ball.pos
```
### 4. **Main Game Loop Adjustments**
The main game loop is updated to handle the replay state.
```python
def run(self):
running = True
while running:
CLOCK.tick(FPS)
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
if not self.replaying:
# Update game objects
self.car.update()
self.ball.update()
# Check collisions
self.check_collision()
# Check for goals
self.check_goal()
else:
# During replay, you might want to disable controls
current_time = pygame.time.get_ticks()
if current_time - self.replay_timer > 2000: # 2 seconds replay
self.replaying = False
self.reset_positions()
# Draw everything
SCREEN.fill(WHITE)
# Draw goals
self.left_goal.draw(SCREEN)
self.right_goal.draw(SCREEN)
# Draw objects
self.car.draw(SCREEN)
self.ball.draw(SCREEN)
# Draw the score
self.display_score()
# Update the display
pygame.display.flip()
pygame.quit()
sys.exit()
```
## **Additional Notes**
1. **Replay Mechanism:**
- The replay is a simple pause where the game waits for 2 seconds displaying a "Goal!" message. During this time, the game objects are not updated, effectively freezing the game to highlight the goal event.
- After the replay duration, the game resets the positions of the car and ball to their starting points.
2. **Score Display:**
- The scores for the left and right teams are displayed prominently at the top center of the screen, updating in real-time as goals are scored.
3. **Goal Visualization:**
- Goals are visualized as green (left) and red (right) rectangles on the respective sides of the screen's edges.
4. **Ball and Car Interaction:**
- The collision detection between the car and the ball remains unchanged, ensuring realistic interactions within the game.
