RedstoneWire isPowered check

Im having a hard time checking if an redstone wire is on it's powered state.
When a redstone wire is powered over a certian block a certain thing will happen.
So if this is possible im forever thankful for ur help
i tried this but it aint working. Material.REDSTONE_WIRE.getData().isPowered();

 

I haven't played around with blocks but I think you should get exact block state (eg. By location) and then do the checks.

 

Of course it doesn't work, where can you see a reference to your block in that line?
You have to get the data from the block: block.getState().getData().isPowered() (or faster: block.getData() > 0)

 

It doesent work it just says that the method isPowered is undefined for materialdata.
Sorry for this but im kinda of an noob to coding redstone shit.

 

Ah I forgot that it has to be casted: ((RedstoneWire) block.getState().getData()).isPowered()

 

Casted from what? Im a so big noob at this. Ive never learned casting. sorry for my stupidness.

 

You have to cast the MaterialData to RedstoneWire to be able to use isPowered:

Code:

((RedstoneWire) block.getState().getData()).isPowered()

or you could simply use

Code:

block.getData() > 0

It's shorter and more efficient, though if you use this you should add a comment why you check the data.

 

I'm googling casting. Thank you very much for your help.
