Solved Executing code when left clicking item

Hello,
How do i execute a code when left clicking an item?
And if you click it removes an item until its 1 and then it removes it.
Thanks for reading

Use the PlayerInteractEvent:

Code:

            if((e.getAction() == Action.LEFT_CLICK_AIR || e.getAction() == Action.LEFT_CLICK_BLOCK) && p.getItemInHand().getType() == Material.YOUR_ITEM)
            {
                //do ydkxakdasdflpad
            }

Are there any values needed like you use in a command?

Code:java

Player player = (Player) sender;

i mean like this

 

Player p = e.getPlayer();

 

nelson2tm

Code:java

@EventHandler
public void click(PlayerInteractEvent e) {   
Player p = e.getPlayer();
if((e.getAction() == Action.LEFT_CLICK_AIR || e.getAction() == Action.LEFT_CLICK_BLOCK) && p.getItemInHand().getType() == Material.YOUR_ITEM)
            {
                if(p.getItemInHand().getAmount() > 1)
p.getItemInHand().setAmount(p.getItemInHand().getAmount() - 1);
else
p.setItemInHand(null);
 
            }
    }

Coded out of scratch so i didn't tested it but should work

 

Jalau And is it possible to make it so, that it does only work with the lore/description (for example): "I like pizza"? and how do i do this?

Code:java

if(p.getItemInHand().hasItemMeta() && p.getItemInHand().getItemMeta().hasLore) {
ArrayList<String> lore = p.getItemInHand().getItemMeta().getLore();
for(String s : lore)
if(s.contains("I like pizza") {
//Your stuff here, if the lore does contains this line two times and you want it to get only executed once add a "break;" at the end of this brackets
}
}

Learn Bukkit & Java, before asking for every problem.
Give us the error code and we might help you....

 

mickedplay What one do you mean? the one from eclipse or the one from the bukkit server console?

 

nelson2tm console

 

he only has an error from eclipse, he cant run this on a server yet

try adding "implements listener" to the "public class thrower" part

 

You forgot to register the events and implement the listener.

Code:java

 
public class Name extends JavaPlugin implements Listener {
 
public void onEnable() {
getLogger().info("Enabled");
getServer().getPluginManager().registerEvents(this, this);
}
 

 

This didn't fix my error :d
the errors on eclipse are:
@EventHandler: EventHandler cannot be resolved to a type
LEFT_CLICK_AIR: LEFT_CLICK_AIR cannot be resolved or is not a field
LEFT_CLICK_BLOCK: LEFT_CLICK_BLOCK cannot be resolved or is not a field

 

Import eventhandler and action

 

Thanks for your help everyone who helped my!
