stop specific player placing blocks/entities

Which event do I need to use, to check if specific players are placing something?

I tried the "BlockCanBuildEvent" but it doesn't tell me which player is trying to place it

please note, it should fire for everything placed, be that a block, tall grass/flower or whatever. (Anti build like)

 

what about BlockPlaceEvent ?

 

Use the BlockPlaceEvent and BlockBreakEvent. If you don't want them to be able to place the block, cancel the event. You'll have to use interact events for certain things like Paintings and Item Frames because they're considered Entities, not blocks.

 

Which interact events?
and thank you

 

PlayerInteractEvent

 

Here is how I'd do it.

Code:java

 
public final HashMap<Player, String> blacklist = new HashMap<Player, String>();
@EventHandler
    public void onBlockPlace(BlockPlaceEvent e){
        Player p = e.getPlayer();
        if(blacklist.containsKey(p)){
            e.setCancelled(true);
        }
    }

Then add people to the HashMap with:

Code:java

 
blacklist.put(p, null);
 

"p" is the player

 

Should never save the Player class, instead save their name.
HashMap(kinda useless and a waste) should be ArrayList and not be final.

Otherwise great job.


blm456 With my highly suggested changes:

Code:java

 
public ArrayList<String> blacklist = new ArrayList<String>();
@EventHandler
public void onBlockPlace(BlockPlaceEvent e){
Player p = e.getPlayer();
if(blacklist.contains(p.getName())){
e.setCancelled(true);
}
}

Then add people to the ArrayList with:

Code:java

 
blacklist.add(p.getName());
