5. Test Your Events and Functions Thoroughly

Before deploying your design, prepare sure all events and functions line as intended. Use stamp statements or debugging tools to scent down any issues.

Conclusion

Functions and events are the building blocks of Roblox scripting. Compact how they oeuvre will expropriate you beget more complex and interactive games.
