Setting timers in simple games (feat. the frame rule)
TL;DR
A simple timer system for games, inspired by Super Mario Bros., is implemented in Lua for quick game development. This approach allows for easy scheduling of future events with minimal code.
✦ Why It Matters
Implement this timer system in your next game jam project to streamline event scheduling.
Key Takeaways
- Use metatables in Lua for default timer values.
- Set timers easily with simple assignments like T.glow=60.
- Implement sound effects based on timer states.
- Understand the frame rule for optimizing game performance.
How It Works
Timers are managed using a Lua table with a metatable that defaults unset values to zero. In the _update function, all timers are decremented each frame, allowing for straightforward event scheduling.
This method is efficient and easy to implement, making it ideal for rapid game development.
