[TUT] Edit Blocks on Sight by Command

First set up a HashMap for the items you can set
This is going to be a example hashmap of some items.
In this case I named it HashMapz

Code:

public class HashMapz {
	public static HashMap<String, Material> items = new HashMap<String, Material>();
	public static void setItems() {
items.put("bedrock", Material.BEDROCK);
items.put("bookshelf", Material.BOOKSHELF);

Now we are going to create the command:

Code:

if (cmdLabel.equalsIgnoreCase("edit") && args.length==1)){
Block target = p.getTargetBlock(null, 200);
			 if (target != null) {
				    Material type = HashMapz.items.get(args[0].toLowerCase());
				    if (type != null) {
				        target.setType(type);
				    } else {
				        p.sendMessage("Invalid block type!");
				    }
				    return true;		
			}
    

By the use of

Code:

if (type !=null){ 

You are also making sure if the user types nothing in or a item that is not on the hashmap it will send them that message of "Invalid Block Type!"

 

Instead of using setItems() once you could use

Code:java

static {
    items.put("bedrock", Material.BEDROCK);
}

aswell.

 

You can set the Distance to 120 as anything above will be set to 120 anyways: See here
