Solved Need help with -Giving player items

Hey, i was trying to make a plugin with a command that will give you an item. For example, i want to make a command /shockwavegive and then the player who does the command will get a diamond pick.

Im am not sure how to do this. Does anyone have a code or something that they could share with me to help please.

My code i have now :

public class ShockwaveGiveCommand implements CommandExecutor {

@Override
public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
if (label.equalsIgnoreCase("item")) {
Player player = (Player) sender;
PlayerInventory inventory = player.getInventory();
inventory.addItem(new ItemStack(Material.DIAMOND_PICKAXE));
return true;
}
return false;
}
}
No errors occure in the software im using. But when i go ingame and do /shockwavegive is doesnt give me it. It just says this in chat.

I was working on the plugin and this is what happens now ^ stated in post now @timtower
I am new to making plugins and i dont really know much about it.

 

What do you mean? as i said, im new to all this developing and making my own plugin. Would you be able to tell me what part of the code i need to change to make it work. Thanks

 

Can anyone else help me? Or even give me a link to someone who has a tread on how to make a basic plugin or a YouTube channel that has tutorials. Thanks

 

Learn Java first as Tim said. You can't run before you can walk - You can do plugin development before you know Java.

 

I know spoon feeding isn't welcomed here, but I'll try my best not to.
First, you gotta check if the sender is a player. If so, create an inventory, not a player inventory, and refer it to sender.getInventory().
Then create an itemstack using ItemStack (name) = new ItemStack(Material.<material name>);
Now, add the itemstack to the inventory.
