How do I get a declared block in command to use in event ?

I want to use a block that I stored in an ArrayList, when you run the command, i am not able to use the same block at the event ... How make?
ArrayListName.contaisKey (block); does not work!

Thanks.

 

You should instead store the location and then get the block at it.

 

ShadyPotato His answer is probably the way to go
??? For example is the block just a Dirt block or a specific instance of a dirt block?

 

ShadyPotato I'm a beginner, could explain better how to do this?

 

Could you explain how the user gets the block i.e. via command or event

 

agent6262 I saved it in an ArrayList, thus:

Code:java

ArrayList<Block> blockList = new ArrayList<Block>();
 
// When you run the command, I put this:
 
blockList.add(player.getLocation().getBlock());

 

What do you want to use the block for?

The line of code you are using to add the block at the players position returns the block where your legs are. With that being said if you are not partly "in" a block I DON'T THINK it will add any thing but i may be wrong.

I want to use the block at an event for when the player stepped on, a sequence of actions occur.

agent6262 I think I will yes, because when you enter the command, the block where the player is automatically stored in the ArrayList.

Regarding what agent6262 mentioned, it will add a block, but that block will in fact be the block containing the player's legs. Here's some code that will store a location and fix that at the same time:

Code:java

List<Location> locations = new ArrayList<Location>(); // as a global
 
locations.add(player.getLocation().subtract(0, 1, 0); // upon running the command

 

zDubsCrazy just did a little googling and found this see if it works

Code:java

player.getLocation().getBlock().getRelative(BlockFace.DOWN)

Ok, so I understand, but for me to use this location on my event?

Thanks for the help, now I understand better!

 

Depends what you want to do. If you want the block, just use Location#getBlock().
