1.21.0 How to get neighboring redstone components to update when a block's output strength changes?

[Tiny Desk Engineer]

I'm making a block that constantly outputs a variable signal strength that can be changed by the player, with the output strength being stored in property, the same one redstone wires use. But while I've gotten it to emit the desired signal strength when placed, if a player changes the strength afterwards, while the block itself changes state as expected, the neighboring components don't update and keep the signal strength, only updating by other means. I've tried various things to get the neighboring blocks to be updated, taken from the code of various vanilla redstone component blocks, but nothing has worked so far. How am I supposed to make this work properly?

Nevermind, RedstoneWireBlock.java had what I needed.

Surprised I didn't try looking there until now.
