Intro To Ruby For Game Development

Build a simple whack a mole game in Ruby for game development, featuring a hammer, moving mouse, mole pop-ups, hit and miss feedback, a score, and a 100-second countdown.

Download mole and hammer images, save them in the project's images folder, create a whack a mole Ruby file, define the class with an 800 by 600 window, and show.

Set velocity x and velocity y to 5; update x and y in the update method to move the mole, and reverse velocity at screen bounds 0, 800, and 600.

draw and center a hammer sprite that follows the mouse, stays visible, and uses image assets and coordinates to build a basic whack-a-mole game in Ruby.

Detect left mouse clicks and determine if the hammer hits the mole within 60 pixels. Update the hit state and draw screen colors to signal hits or misses.

Set a 60-second countdown, manage the game state with a playing state, and draw the timer and a game over message when time runs out.

Finish implementing replay prompt for the whack a mole game by drawing a 'press space bar to play again' message after game over and reset time and score on restart.

Package your Ruby game into a Windows executable using the Ocra gem, by installing it and running a command from your game directory, naming the output file, and including images.
