    Hello again Bukkit!

    Today I'm wondering how I'd set a chest's name/title when placing a block at a location.

    My plugin is a loot chest plugin, and I'd like to make it so that if the chest's name is "Loot Chest" then to execute some code.

    When I place a chest with the name Loot Chest, it'll store the chest's world, location, and direction it's facing in the config.yml. Then when the server starts up it'll place those chests at the specified locations. Right now I have it set so that when you open any chest it'll create a virtual inventory with the correct name, though I'd like to make it so that it'll only happen for certain chests.

    I do know how to get a chests name though, so checking for the name won't be a a problem, just setting it when the item is placed.

    Thank you in advance to anyone who may be able to help out with this.

    Here is my current code:

    @oceantheskatr Just has a method to get the title and none to change it. Just like the inventory.But you can instantiate an Inventory and define the name with the constructor via Bukkit.createInventory(). This just doesnt seem to be the case with a Chest. You can't instantiate is as there are no Classes which implement it. And you cant create it afaik with the Bukkit API. So i would conclude, that i have no idea, and didn't find anything to change it. You could try to store all lootChests in a file, create a for example HashSet (you may need a volatile or a synchronized, if two threads access the set at the same time) with the Location. Then check if the block.getLocation() from the OpenIvEvent is in that set, and react based on that. Saving could be done with a StringList, like you did.

    @I Al Istannen Alright thanks for the response! I think I'll try using those chest locations to decide whether or not to open the custom inventory. Do you think it would be possible to give the chest some sort of metadata when creating it? Then check to see if it has that metadata when opening it?

    @oceantheskatr Yes. The only problem is that metadata are not persistent. They get deleted when you reload or restart the server. Use block.setMetadata() and block.hasMetadata() and block.getMetadata() (you can get a description of the metadata methods here:

    Metadata types:

    I'd be adding it in the same area as where I place the chests, and where I respawn them after breaking :)

    @oceantheskatr So it would't be required to have them persistent. Then Metadata might be the better way. You don't have to worry about storing, reading or other things, so try it out :D

    Alright I'll be sure to!
