While block is in world change it to another after x amount of time

[tal124]

Hello, I've seen mods like blood alchemy turn liquid blood into blocks and AE2 turn Certus seeds into full formed pure Certus quartz, I was wondering how I would go about setting it so that once my block (Copper ore) is set down in the world for long enough that it will turn into oxidized copper ore (just as a way to see if I can) I have no idea where to start with this kind of code and it may come in handy later if I wish to start an actual project of my own

and would it also be possible to speed up the process when next to another block or liquid like water?

Look at how Minecraft handles farmland turning wet when next to water and how crops grow.

I've found it and I've looked it over but I'm not too sure which section is referring to a change in block type back to dirt, and I see the "turnToDirt" parameter and I don't fully understand it

I've been putting some of the code into my own, but I'm not sure how this will actively switch my own block
