Description:


This tutorial allows you to make a fully funtional clock and calendar in RPG maker MV. (Works also in MZ) This system, includes:
  1. A fully functional 24 hour clock, with hours and minutes.
  2. A fully functional 365 day calendar, with days, months and years, starting at the date of your choice.
  3. Day/night cycles.
  4. Inside and outside lightning according to day/night
  5. Events that only arrive during day or night or even certain hours, like
    • breakfast, dinner, lunch
    • nightly monsters
    • merchants that close late at night
  6. Seasonal maps
  7. In game holidays
  8. Buffs/debuffs for being fed/hungry*, for being hydrated/thirsty* and for being rested/tired*
  9. Skipping time by sleeping
  10. And much more.



How does it work:

This tutorial is written inside events and common events in an example project. This means you have to download the project (only 4 Mb) and open it in MV. Now you can check the events and common events to see how I did what.

Everything I did in those events and common events, I explained in comment notes.

Screenshots explain this a lot better than words. The green text in me explaining the system:

Start a test run first to see how things go in practice, or start reading the events right away. Either way, make sure you read common event #2 before you read the other events. I've named that "ClockCore" and is the whole engine that makes the system.



Events only
The entire system is made with purely events. No coding is used. However, the project does have a tiny little plugin delivered with it. It is made (by me) to trigger a common event on map transfers. I use this to trigger the clockcore after every transfer in my own projects. I disabled the plugin for this project, to show how everything can be done with only events.

Suggestions are welcome
I will keep improving this project over time, so if you have any suggestions for examples what to do with the time system, feel free to leave a comment.
