Solved BlockState to config?

hey guys!
Iam doing a plugin for myself but I stuck at one point.
When I try to save a BlockState List to a config. I can convert it to a string but not the other way round.
My plugin:
- When I do a command the player gets into a kind of edit mode. Every placed block is saved to an array.
- When the player uses another command I want those blocks spawned on his location.

How do I get this work?

Any help?
Thank you very much!!!

 

create the list

Code:

List<Location> blockLocations = new ArrayList<Location>();

get blocks

Code:

Block b1 = world.getBlockAt(100, 100, 100);
Block b2 = world.getBlockAt(1000, 1000, 1000);

adding the blocklocations to the list

Code:

blockLocations.add(b1.getLocation());
blockLocations.add(b2.getLocation());

saving block locations into the config:

Code:

this.getConfig().set("BlockLocations", blockLocations);
this.saveConfig();

get the location of the block again:

Code:

Location l = (Location) this.getConfig().getList("BlockLocations").get(0);

i hope thats want you ment and i hope it helped

greetings

 

Why can't you convert the other way?

 

Code:

public String serializeLoc(Location l){
    return l.getWorld().getName()+","+l.getBlockX()+","+l.getBlockY()+","+l.getBlockZ();
}
public Location deserializeLoc(String s){
    String[] st = s.split(",");
    return new Location(Bukkit.getWorld(st[0]), Integer.parseInt(st[1]), Integer.parseInt(st[2]), Integer.parseInt(st[3]));
}

to save the location just do this :

Code:

getConfig().set("path", serializeLoc(location));

to get a location from the config :

Code:

Location location = deserializeLoc("path");

 

yes thats also a method to do but he said he already got a list so i think this is an easier way to to

Code:

this.getConfig().set("BlockLocations", blockLocations);
this.saveConfig();

cause else he has to add everything with a for loop

 

first off all thank you all four your answers!

Yes I allready tried that but then it gives me an error, because its not able to save a BlockList like this.
Thats my Array:

Code:

public List<BlockState> blocklist = new ArrayList<BlockState>();

And thats what I tried:

Code:

    @EventHandler
    public void onBlockBreak(BlockBreakEvent event){

    blocklist.add(event.getBlock().getState());
     
    }
    

And of course I saved it with saveConfig();
the same way as you said.

@sn1cko

sorry It doesnt allows me to load the saved blocks!
Error:
ENDLESS nullpointer exception

EDIT by Timtower: merged posts

 

why dont you save the Location of the Block or the Block itself ?

 

Location is not ConfigurationSerializable.

 

i see but you could save world,x,y,z and create a new Location onEnable()

i think that should work

try to save the cordinates and the world and also the material
and if you need it you can build your own block ^^

 

The class I use: https://github.com/CodeLanx/Codelan...codelanx/codelanxlib/serialize/SLocation.java

Allows making Locations serializable via:

Code:java

Location loc = /*...*/;
getConfig().set("example", new SLocation(loc));
SLocation fromConf = getConfig().get("example");
loc = fromConf.toLocation();

 

This..... I like.

 

Thanks all! Helped me alot!
