[Archive]C# Scripts

I have completed the writing of almost all the C# scripts we need. Specifically:

1. Press the L key to summon candy rain, and the candy will bounce slightly after landing

2. Press the J key to switch between dusk and night, and all lighting systems will change at the same time

3. Collectible items will temporarily change the player's speed after collecting (there are some minor bugs at present, still testing)

As long as the model is completed, these functions can be used directly
