BLWarps is a Sponge plugin for easily setting locations for players to warp to.

Note: In the following commands, square brackets ([]) indicate optional arguments, and angle brackets (<>) indicate required arguments.

• /warp set <warp name> [x] [y] [z]
• Create a new warp with name warp name and optional coordinates (x, y, z).
• /warp <warp name>
• Warp to the warp with name warp name.
• /warp delete <warp name>
• Delete the warp with name warp name.
• /warp list
• List all of the currently active warps.
• Only the warps that the CommandSource has permission to use will be displayed to them
• /warp info <warp name>
• Displays information about the specified warp

• /warp group add <warp name> <group name>
• Add the warp with name warp name to the group group name.
• /warp group remove <warp name> <group name>
• Remove the warp with name warp name from the group group name
• /warp group removeall <group name>
• Remove all warps from the group with name group name
• /warp group info <group name>
• Displays information about the specified warp group

• /warp region set <region name> <warp name> <corner1> <corner1>
• Create a new warp region with name region name, linked warp with name warp name and corners corner1 and corner2
• /warp region delete <region name>
• Delete the warp region with name region name.
• /warp region list
• List all of the currently active warp regions.
• /warp region info <region name>
• Displays information about the warp region with name region name

A warp region is an area in a world in which a player will be warped to any arbitrary warp if they enter the region. Currently, there is no support for WorldGuard regions, but it is a planned feature. See the Warp Region Commands section above for instructions.

Warp signs can be created for any previously established warp. To do this, simply place a sign anywhere in the world, and write the following text on each line:

1. [Warp]
2. <warp name>
3. Doesn't matter
4. Doesn't matter

If you have correctly placed the sign, the text on the sign will be colored and reformatted. To use the sign to warp, simply right click on the sign.

Permissions can be required for either individual warps, or warp groups, as shown below:

• blwarps.warp.<warp name>
• blwarps.warp.group.<group name>
• blwarps.warp.* (wildcard --> warp to anywhere)

Regardless of the storage solution, each warp has 5 properties:

• name - the name of the warp
• world - the name of the world that contains the warp
• x - the x coordinate of the warp (stored as a double)
• y - the y coordinate of the warp (stored as a double)
• z - the z coordinate of the warp (stored as a double)

And optional properties:

• groups - the groups of which the warp belongs to

For flat file storage, warps are stored as JSON (serialized using Jackson) in the config/BLWarps/warps.json file. A sample warps.json file would be similar to the following:

[ {
    "name" : "warp1",
    "world" : "world",
    "x" : 40.3,
    "y" : 41.0,
    "z" : 72.07,
    "groups" : [ "group", "group2" ]
}, {
    "name" : "warp2",
    "world" : "DIM-1",
    "x" : 7.63,
    "y" : 64.0,
    "z" : 11.79
} ]

Any JDBC-compatible database is a valid option for storing warps. The JDBC connection URL must be specified in the sql.connection-url. By default, the Warps will be stored in the warps table. Currently, the name of the table cannot be changed. BLWarps uses JDBI for executing queries and mapping results to a Warp object.

For REST-based storage, HTTP requests are sent using the Jersey Client to the URI specified by the rest-uri field in the configuration. Currently, only basic authentication is available, which uses the rest.username and rest.password credentials (by default, they are root and pass, respectively). The plugin will send the following requests, and will expect the application/json media type as part of the response:

• GET when loading warps - must receive a List of Warps
• POST when saving a new warp
• DELETE when deleting a warp. The warp's name will be a path parameter.
• Ex: http://localhost:8080/warps/deletethiswarp
• PUT when updating a warp (adding/removing groups)

BLWarps uses Maven as a dependency manager and build tool. To build the plugin from source, make sure Maven is installed, and run mvn clean install. The newly built plugin will be in target/bl-warps-{version}.jar. For developing, run the Maven build once, then add the target/generated-sources/java-templates directory as a source folder (see graphic below for how to do this in Eclipse).
