Spigot plugin which allows displaying PlaceholderAPI placeholders on signs.
To register a sign as a dynamic placeholder display look at it and type /sph add <text>. This will put <text> on the sign and replace all placeholders. To split text into multiple lines use | character. For example this command: /sph add | Score: | %some_score% will add a sign with Score: text on the second line and the %some_score% placeholder on the third line.
To unregister a sign look at it and type /sph del or simply break it.
To reload the plugin use /sph reload. It's only needed if you edit the config.yml file manually. Please don't do that though, it may cause errors if you make a mistake.
To change the update interval of signs use /sph interval <number>, where the number is amount of ticks between each update.
To change the range around players in which the signs are updated use /sph range <number> where the number is a radius in blocks.
