Don't know how to go further.

Dear,
This is my code at the moment this piece off code will check when the player run the command logtowood1 of they have a log in theire inventory. I they have it will run a specifiq spiece of code. (now it will send the message found) I want it to remove 1 logg from theire inventory and replace it to wood planks. How can I do this?

Code:java

 
package me.rubenio1.test;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.Material;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.HumanEntity;
import org.bukkit.entity.Player;
import org.bukkit.event.Listener;
import org.bukkit.inventory.Inventory;
import org.bukkit.inventory.ItemStack;
public class Test extends JavaPlugin {
 public void onEnable() {
 getCommand("logtowood1").setExecutor(new EventsClass());
 }
 public void onDisable() {
 }
 public class EventsClass implements Listener, CommandExecutor {
 public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
 if(sender instanceof Player) {
 if (cmd.getName().equalsIgnoreCase("logtowood1")) {
  Inventory i = ((HumanEntity) sender).getInventory();
  for(ItemStack inven : i.getContents()){
    if (inven == null) {
    continue;
   }
  if(inven.getType().equals(Material.LOG)){
  sender.sendMessage("found");
  }
  } 
 }
 }
 return true;
 }
 }
}

I think something like this should work:

Code:Java

sender.getInventory().removeItem(inven);

 

inside the if(has log...) {}

Code:java

sender.getInventory().remove(inven.getType()); //dont know how many logs there will be removed
for (ItemStack is : sender.getInventory().addItem(new ItemStack(Material.OAK_PLANKS)).values()) {
    sender.getWorld().dropItem(sender.getLocation(), is);//this is for when the player doesn't have space left, so it will be droped
}

The addItem will return a HashMap of the items that could not be added

 

Thnx, Does anyone know how to specify an amount on the code of @The_Spaceman (for the amount of wood that will be removed)

 

The itemstack you've checked is an itemstack with the material log. You can remove 1 of the amout value, and when that is 1 remove the itemstack. Or you can check how many will re removed by just testing of how many there will be removed…

 

But is it also possible to give them 4 planks back and another question, can you specify the type of logg. Because now you only have logg and logg_2 with auto correction on eclipse.

 

add more items:

Code:

new ItemStack(Material.YOUR_MATERIAL, 4)

the 4 is the amount of items

if you program with Bukkit 1.13:
they replaced it all. so now you have OAK_PLANKS and ACACIA_LOG, etc...
in lower than 1.13:

Code:

new ItemStack(Material.LOG, 1 /*amount of items*/, 2 /*damage value*/)

I say you have to update your server to 1.13 because everything else is going to be outdated soon...

I hope this will help you.

 

Then I can do that but the pl is needed for 1.12.2 is that possible?
(the error when doing the command in 1.12.2: https://pastebin.com/QRdVuM7N)

Found it, thnx

One last question: Is it possible to specify a type of wood in the detection: if(inven.getType().equals(Material.LOG)){
@The_Spaceman

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

 

If you want to check what type of log it is, you need to check the damagevalues...
'.getDurability()'

 

Where do I need to place it? (tried many places in the invent.getType)

 

Code:Java

if (/*your itemstack*/.getDurability() == /*number here*/) {

 

https://gyazo.com/6e526a1b59b2b15420d4168d28e5fb93
It says that you must change it to getMaxDurability. (look link)

 

Like this?
if(inven.getType().equals(Material.LOG)){
if(inven.getDurability() == (2)){

 

Code:Java

 
  if(inven.getType().equals(Material.LOG)){
    if(inven.getDurability() == (2)){
    ((HumanEntity) sender).getInventory().remove(inven.getType()); //don't know how many logs there will be removed
    for (ItemStack is : ((HumanEntity) sender).getInventory().addItem(new ItemStack(Material.LOG, 1 /*amount of items*/, (short) 2 /*damage value*/)).values()) {
    ((Entity) sender).getWorld().dropItem(((Entity) sender).getLocation(), is);//this is for when the player doesn't have space left, so it will be droped
    }
  }
    if(inven.getDurability() == (1)){
    ((HumanEntity) sender).getInventory().remove(inven.getType()); //don't know how many logs there will be removed
    for (ItemStack is : ((HumanEntity) sender).getInventory().addItem(new ItemStack(Material.LOG, 1 /*amount of items*/, (short) 1 /*damage value*/)).values()) {
    ((Entity) sender).getWorld().dropItem(((Entity) sender).getLocation(), is);//this is for when the player doesn't have space left, so it will be droped
    }
  }
  }
 

If I do this is just doesn't response @timtower

 

what do you mean by print it? @timtower

 

if(inven.getDurability() == (1)){
Bukkit.getLogger().info("1");
I have done this but nothing is comming thru in the console

 

Found it, normal wood 1 dur. 0.
But how can you specify how much wood theire will be removed.
((HumanEntity) sender).getInventory().remove(inven.getType());
or better how can you let It go if you have 2 oak loggs and 3 pruce loggs (example <-) that you also get 2 oak planks and 3 spruce loggs back?

 

((HumanEntity) sender).getInventory().remove.inv.ItemStack(Material.WOOD, 1 /*amount of items*/, (short) 1 /*damage value*/);
somethinh like this doesn't work

 

And how can you make it remove 1 wood? I can't find it

 

But how do you use it. This doesn't work: ((HumanEntity) sender).getInventory().remove(inven.getType(), 1);

 

I tried a lot off things but I just can't find it / don't get wat you mean. (with the itemstack)
