"制作打地鼠游戏；制作打地鼠游戏，制作自定义鼠标指针，完成代码解释。"

e a Whack a Mole game using GameMaker as an exercise. We start by creating sprites of 32x32 pixels for the mole and the hammer. Then, we create objects for each of these sprites and an additional object called control. To make the game more interactive, we need to change the default mouse cursor to a custom one. We add an event in the control object and write a script to change the cursor sprite and make the Windows arrow disappear. The main objective of the game is to whack the moles that randomly appear on the screen using the hammer. The player earns points for each mole successfully whacked within a certain time limit. The game gets progressively harder as the moles appear faster and in different locations. This exercise allows us to practice creating sprites, objects, and events in GameMaker. It also helps us understand how to create interactive games and customize the user experience by changing the mouse cursor. The Whack a Mole game is a fun and engaging way to learn game development and improve our skills in using GameMaker.
