请求帮助：实现按下上箭头时小立方体切换为高立方体功能

Hey there! I totally get how crucial this feature is for your game—nothing’s more frustrating than a core mechanic not landing when you’ve got a creative vision to execute. Since you mentioned you’ve already tried some approaches without luck, let’s narrow down the problem by covering a few key details:

• First off, what game engine or framework are you using? (Unity, Godot, Phaser, raw JavaScript/HTML5, or something else entirely?) Different tools handle input and object manipulation in totally different ways, so this is a big one.
• Can you share the code snippets you’ve written for handling the up arrow press and the cube switch? Wrap them in backticks so they’re easy to read—even if you think it’s “broken” or messy, seeing the actual implementation will help spot where things might be going wrong.
• When you test this, do you notice any odd behavior? For example: Does pressing the up arrow do nothing at all? Does the game register the key press but the cube doesn’t change? Or maybe it changes once but won’t switch back (if that’s part of your plan)?
• How are you defining the “small cube” vs “tall cube”? Are you swapping between two different prefabs, adjusting the cube’s scale property, or using some other method?

Once you share these details, we can dive into exactly why the switch isn’t working and get your game’s core mechanic up and running in no time.
