Python Keyboard Jump Game using PyGame

The python keyboard jump game is a fun game that helps in increasing the typing speed of the player. In this game, random words are displayed and the player has to type the word correctly before the word disappears and if the word is misspelled the player loses the game, otherwise the score is incremented.

We will use pygame to develop this game. It is a python module with sound and graphics libraries for developing video games. Let’s check the pre-requisites.

Project Prerequisites

We just need pygame for this project, Command to install:

pip install pygame

Explanation:

• GenerateWord: In this function, we are choosing a random word from wordList using the random module. And after that, we are storing it in currWord and reinitializing playerWord.
• PutText: In this function, we are simply blitting the word on the pygame window.
• displayScreen: In this function, we are displaying the initial screen (when the game is not started) and then it waits until the player presses the enter key to start the game. It is also responsible for displaying the final score and game over message.

Python Keyboard Jump Game Output

Summary

We have successfully Python Keyboard Jump Game using Pygame. You can change the background image, fonts, character, speed, or any other values to make it more interesting.

Happy Coding !!!
