In forge 1.20.1 how do I make a block that spreads to other blocks surrounding it?

[SlayerOfDragons]

I wanna make a corrupted block in my minecraft mod and I was wondering how I would do that with a playertickevent or detect if the block was placed and go from there? (This is forge 1.20.1)

Look at SpreadiingSnowDirtBlock.randomTick() and call Properties.randomTicks() when you register your block.

You can look at the code for skulk or snow or grass they all have feature that grow, you can also look at kaupenjoe's grey goo mod and look there
