Detect when block receives redstone power

[neotardo]

I'm new to modding, and I'm working with Forge 1.16.3 in Eclipse. I made a custom block, and there's really not much to it, but I want to detect when the block receives redstone power. I've seen several old posts saying to check how vanilla blocks do this, or how the redstone diode works, but it's still pretty unclear how I would go about detecting redstone power. Would this be an event of some kind?

Your first thought when modding should always be:

"I wonder if any existing vanilla blocks have this feature. Maybe I should go look at their classes to see how they handle it..."

Hi

 

There are a few working examples of redstone in this tutorial project

Redstone power has a few different things to understand, in particular weak power and strong power.  The link above has more explanation.

 

Cheers
