How to create Buttons in a game using PyGame?
Pygame is a Python library that can be used specifically to design and build games. Pygame only supports 2D games that are build using different shapes/images called sprites. Pygame is not particularly best for designing games as it is very complex to use and lacks a proper GUI like unity gaming engine but it definitely builds logic for further larger projects.
Before initializing pygame library we need to install it. This library can be installed into the system by using pip tool that is provided by Python for its library installation. Pygame can be installed by writing these lines into the terminal.
pip install pygame
Creating interactable buttons using pygame
A game must have interactable buttons that can control different events in the game to make the game more controlled and to add a proper GUI in it. These can be created in pygame by creating a rectangle onto the screen and then superimposing the indicating text on it. For this, we will be using various functions like
screen.blit() etc. To add more liveliness to it we can change the color of the button as the mouse has hovered on it.
This can be done by using a function that updates the x and y position of the mouse pointer and storing it as a tuple in a variable. Then we can set the boundaries of the rectangle into respective variables and check if the mouse is in those boundaries if so the color of the block will be changed to lighter shade to indicate that the button is interactable.
Below is the implementation.
