I need help with the Material API

I'm very new to programming, and I no it's not great to jump into things you don't know. But I thought I would give it a try. Right now I'm trying to learn how to use the Material API. I have everything imported , but I was wondering how do I actually make a new item?

 

@WasabiLoverMake a new item or ItemStack? The first is impossible.

To make a new item stack do

Code:

ItemStack itemstack = new ItemStack(Material.NAME);

Thanks i'll try that!

Here is what I have so far...

package me.WasabiLover.Plugin;


import me.cybermaxke.materialapi.material.CustomMaterial;
import org.bukkit.Material;
import org.bukkit.event.Listener;
import org.bukkit.event.block.BlockBreakEvent;
import org.bukkit.event.block.BlockDamageEvent;
import org.bukkit.event.block.BlockPlaceEvent;
import org.bukkit.event.entity.EntityDamageByEntityEvent;
import org.bukkit.event.player.PlayerInteractEntityEvent;
import org.bukkit.event.player.PlayerInteractEvent;
import org.bukkit.event.player.PlayerItemHeldEvent;

public class MyCustomMaterial extends CustomMaterial implements Listener{
public MyCustomMaterial(String id, Material material) {
super(id, material);
}
public void onHit(EntityDamageByEntityEvent event) { }
public void onInteract(PlayerInteractEvent event) { }
public void onInteractEntity(PlayerInteractEntityEvent event) { }
public void onBlockPlaced(BlockPlaceEvent event) { }
public void onBlockBreak(BlockBreakEvent event) { }
public void onBlockDamage(BlockDamageEvent event) { }
public void onBlockInteract(PlayerInteractEvent event) { }
public void onHold(PlayerItemHeldEvent event) { }

}
My question is how do I make this new Item possible to get in game?

@xxMOxMOxx Sorry I know my questions are not very straight forward. Ok so I've used the ItemStack itemstack = new ItemStack(Material.NAME); how should I make a new Id?

That's a lot of Events to handle for a first time programmer. Looks as if you're trying to make a logger of some sort. Anyways, don't give up. It is usually best to learn some Java then go to plugins but I'm sure you'll do just fine

 

Thanks I think I may have gotten it. I guess I'll have to launch my server and see

If you could use some additional help just add me on Skype: retrocraft.mc

first of all can you use the [.CODE][/.CODE] without the . so that we can see it more clearly

Is this better? Sorry also new to the forums. I think I have the plugin working but do I need to install the Material API, if so how would I go about doing that?

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

 

WasabiLover It sounds like you are missing a library or another plugin. Where does
import me.cybermaxke.materialapi.material.CustomMaterial;

come from? Is it another plugin?

 

It comes from the Bukkit MaterialAPI

 

It sounds like you didn't install that on your server.

Edit: also, even though you call it "Bukkit", note that it isn't official. Bukkit does not use package me.cybermaxke

 

I have read over your post and it says your new to java and the bukkit api, i would highly recommend not doing this as my friends decided to do this since they couldnt be botherd and wanted to be able to help me or do what i can do but as the had no previous java knowledge it has took them twice as long to get the basics than it did for me. I would recommend watching these tutorials.

For detailed tutorials which most people most likely learn from is:
http://www.youtube.com/user/thenewboston

He has Beginner:http://www.youtube.com/playlist?list=PLFE2CE09D83EE3E28
And Intermediate: http://www.youtube.com/playlist?list=PL27BCE863B6A864E3&feature=playlist-comment

 

Thats odd because I found a link from the forums. It comes from this link:
https://forums.bukkit.org/threads/materialapi-create-new-items-and-blocks.123851/
And I believe I've installed it properly

Thanks, I've already watched several tutorials but I never found anything quite like what I'm currently trying to do.

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

 

Another way you could try is looking through the resources section of the bukkit forums. Im sure iv saw 1 or 2 Material Api Tutorials but i dont have the time too look
http://forums.bukkit.org/forums/resources.60/

 

Thanks! I'll try them out.

 

WasabiLover From what I understand, you need to have MaterialManager in your plugins folder. http://dev.bukkit.org/bukkit-plugins/mater/
Notice there are 2 downloads, the MaterialAPI and MaterialManager.

 

Ok i'll try that thanks.
