@davekov5
Can you please paste your code? There is an error in class "Main.java" at line 57. But if you don't show what's in there, I cannot help you

 

@Erumeldor

if (e.getItem().getItemMeta().getDisplayName() == null) {
return;
}

@Erumeldor
@EventHandler
public void onInteract(PlayerInteractEvent e) {
Player p = e.getPlayer();

if (e.getItem().getItemMeta().getDisplayName() == null) {
return;
}


if ((e.getAction() == Action.RIGHT_CLICK_AIR) && (e.getItem().getType() == Material.STAINED_CLAY)
&&(e.getItem().getItemMeta().getDisplayName().equals(ChatColor.translateAlternateColorCodes('&', "&aasd")))) {
if(e.getPlayer().isOnGround()){

p.sendMessage("u are on the ground");

} else {

p.sendMessage("u are not on the ground");

}
}
}

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

@davekov5
Change "&aasd" to "§" here;

Code:

ChatColor.translateAlternateColorCodes('&', "&aasd")))) {

Aren't you able to use replaceAll("&", "§") instead?

 

@yPedx
NO. Do not add paragraph symbols. There have been many threads discussing this. If you want to add color to text, use Chatcolors. If you want the chatcolors or strings to be configurable, then you would use TransleateColorCodes.

@davekov5
The item can be null. You have to null check item before getting the item meta, and you have to check if the item has item meta before getting the display name. That is most likely what is causing the problem.

 

@davekov5 Don't know if this awnser's you're question but you don't need a curly bracket for returning something. Simply just return it like so:

Code:

if (e.getItem().getItemMeta().hasDisplayName() == null) return;

Also, from what zombie said, you're checking the if the item by using a get method, and that's not going to go well for you. I updated the code, didn't notice it to be honest, but you should fix that as well.

 

@Ragnarok_
Don't null check the string, as it would be a blank string if the display name dis not exist. Instead, use hasDisplayName()

 

Thanks i will try it
