[SOLVED]If a block is powered by redstone...

I know I need to use the isPowered() method, but can someone give me a code snippet of what I would use to see if a block is powered by redstone, and then do X.

So:
If Block A powered by redstone
Do X action.

Im not sure how to do this exactly... please help.

Code:

        Block block = event.getPlayer().getLocation().getBlock(); // probably air
        if (block.isBlockPowered()){
            block.setTypeId(50);
        }

This will just set the block the player is in to a torch if powered, this is probably difficult to do though. Just for an example.

 

@LaLa thanks for that example. I was looking more into something like if a lapis block is powered, spawn a mob, for example. The example you gave is only for the block they are on, correct?

 

No, it's the block that their legs are in

 

Correct.
Same thing to check if it's not powered, but add == false

Code:

if (block.isBlockPowered() == false){}

 

if you're using booleans in a conditional, you can use the NOT operator !

Code:

if (!block.isBlockPowered()){}

 

This is a tough one for ideal practicality. There is an event for redstone change at which point you can check for lapis lazuli or whatever, but it is only called when redstone wire or other redstone driven blocks change their powered state. You have to check around the wire for a lapis block, then check its power state with block.isBlockPowered(). What I ended up doing was creating a scheduled task to run through my blocks to test for power, but that is not all that feasible for lapis lazuli blocks because you dont have a Collection of them all stored. Does anyone else have a better solution?
