Meseport
A mod for Minetest
When used with the "default" mod, this mod allows you to teleport by means of Mese and Gold structures. You punch a gold block that's next to Mese to teleport 100 meters in the direction that the Mese is located relative to the gold block. Each additional Mese added in a straight line adds an additional 100 meters. You can also add Mese to multiple sides in such a way to go in diagonal directions! However, Mese on opposing sides cancel each other. Thanks to oscar14 for the Gold-Mese-Transport idea!
If the default mod is not installed, another mod will need to use meseport's API to set what nodes it uses.
API
meseport.register_actionblock(node_name) - A method that sets a particular node type to trigger a meseport teleport when punched. When the default mod is installed it will automatically be called with meseport.register_actionblock("default:goldblock").
meseport.nodepowers - A table that determines how far an adjacent node of a particular type will send the puncher. For example, when the default mod is installed this table will be:
{
["default:mese"] = 100
}
