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?
