LogoutBouncing Yellow Ball in Rotating Square Animation
This video demonstrates how to use the Bouncing Yellow Ball in Rotating Square Animation template.
import pygame
import sys
import math
# Pygame initialization
pygame.init()
WIDTH, HEIGHT = 800, 600
screen = pygame.display.set_mode((WIDTH, HEIGHT))
clock = pygame.time.Clock()
# Square parameters
square_center = (WIDTH // 2, HEIGHT // 2)
half_side = 200 # half the length of one side
angle = 0 # initial rotation angle (in radians)
rotation_speed = math.radians(0.5) # slow rotation speed
# Ball parameters
ball_radius = 10
ball_color = (255, 255, 0) # yellow
ball_pos = [WIDTH // 2, HEIGHT // 2]
ball_speed = [3, 2] # initial velocity
def rotate_point(point, center, theta):
"""Rotate a point around a center by theta radians."""Frequently Asked Questions
Include it in a subscription-based animation template library Q3: What industries would benefit most from this type of animation?
Several industries can leverage this animation effectively: - Education sector for physics and mathematics visualization - Gaming industry for puzzle game mechanics - Digital advertising for eye-catching displays - Software development for UI/UX elements - Scientific visualization for particle behavior demonstrations
Q4: How can I modify the ball's speed and behavior in the animation?
A: You can adjust the ball's behavior by modifying the ball parameters in the code. Here's an example:
```python
Increase speed
ball_speed = [6, 4] # Double the original speed
Change ball size and color
ball_radius = 15 # Larger ball ball_color = (255, 0, 0) # Red color
Add acceleration
def update_ball(): ball_speed[1] += 0.1 # Add gravity ball_pos[0] += ball_speed[0] ball_pos[1] += ball_speed[1] ```
Q5: How can I add multiple balls to the animation?
A: You can create multiple balls by using a list of ball objects. Here's an example modification:
```python
Create a Ball class
class Ball: def init(self, x, y, speed_x, speed_y): self.pos = [x, y] self.speed = [speed_x, speed_y] self.radius = 10 self.color = (255, 255, 0)
Initialize multiple balls
balls = [ Ball(WIDTH//2, HEIGHT//2, 3, 2), Ball(WIDTH//2, HEIGHT//2, -2, 3), Ball(WIDTH//2, HEIGHT//2, 2, -2) ]
Update and draw all balls in the main loop
for ball in balls: # Update position and handle collisions # Draw each ball pygame.draw.circle(screen, ball.color, (int(ball.pos[0]), int(ball.pos[1])), ball.radius) ```

Bouncing Yellow Ball in Rotating Square Animation
This template creates an interactive animation featuring a yellow ball bouncing within a rotating square. The animation demonstrates smooth collision detection and continuous motion.
Getting Started
- Click "Start with this Template" to begin using this template in the Lazy Builder interface
Test the Animation
- Click the "Test" button to launch the animation
- A dedicated display link will be provided through the Lazy CLI
- Click the provided link to view the animation in your browser
Using the Animation
When you open the animation, you'll see:
- A white square that slowly rotates in the center of the screen
- A yellow ball that moves and bounces within the boundaries of the rotating square
- The ball will automatically bounce off the square's edges, maintaining continuous motion
- The animation runs continuously until you close the browser window
The animation demonstrates: * Smooth rotation of the square * Accurate collision detection between the ball and the square's boundaries * Continuous ball movement with proper velocity changes after collisions * Coordinate system transformations to handle collisions in a rotating reference frame
This is a self-contained animation that runs automatically and doesn't require any additional setup or integration steps.
