Pygame-Linked-List-Visualizer

"Pygame Linked List Visualizer" - This project presents an example of an animated linked list created using the Pygame library. Each node is represented as a circle, and the connections between the nodes are shown with colored lines. Additionally, this animation moves the node list according to the mouse position and offers customization options for the growth rate, position, and connections of the nodes.

Requirements

• Python 3
• Pygame

Installation

1. Install Python 3 on your computer.
2. Download or clone the project to your computer.
3. Open the terminal or command prompt and navigate to the project directory.
4. Run the pip install -r requirements.txt command to install the required libraries.
5. Launch the program by running the main.py file.

Usage

This project uses the LinkedList class to provide visual representation of the linked list. The AnimatedList class extends the LinkedList class to make the linked list animated. Additionally, it is possible to customize the appearance of the linked list by adjusting growth rate and position modification functions.

File Description:

Value	Description
main.py	This file is the main file where the process of creating the animated graphic takes place.
constants.py	This file is a file where constants are defined. These constants include various values used in the process of creating the graphic.
linked_list.py	This file is a file where the linked list data structure is defined. This data structure is used in the process of creating the graphic.
animated_list.py	This file is a file where the class for creating an animated graphic using the linked list data structure is defined.

Customization:

The following options are available to change the connections and positions of the nodes:

Value	Description
growth_rate_function	Takes a function to determine the growth rate of the nodes. By default, the x/50 function is used. (In the recursive function, as each node is updated, the growth rate is taken as an input and is used to determine the actual growth rate of the node by calling the growth rate function.)
pos_modifier_function	Takes a function to determine the position of the nodes. By default, the math.cos(z)*50 and math.sin(z)*50 functions are used. (It provides extra movement to the node by taking the node position and other data and adding the data returned from a specially defined function to it, thus allowing for customized movement.)
draw_links	Determines whether the connections should be drawn or not. By default, it is set to True.
draw_nodes	Determines whether the nodes should be drawn or not. By default, it is set to True.

Customization Details

To customize this project, you can follow these steps:

• Change the constants in the constants.py file. For example, you can change the growth rate of the nodes GROWTH_RATE or change the NODE_FILL constant to draw nodes instead of filling them.
• Customize the growth rate, position, and connections of the nodes by modifying the init function of the AnimatedList class. For example, you can change the growth_rate_function and pos_modifier_function functions to adjust the position and growth rate of the nodes.
• Customize the movement of the nodes by modifying the animation_update function of the AnimatedList class. This function allows the connections of the nodes to be drawn and their positions to be updated.
